Quartz Countertop Stain

Can quartz countertops stain? Ask most homeowners and they’ll likely say, "Nope. quartz is non-porous." The reality is that stains in quartz countertops can and do occur. Especially white quartz countertops. Why? How? What can you do about it? All is answered below...

collage of quartz countertop stains - text overlay - learn the real story about quartz countertop stains

Stains in quartz countertops are different than stains in granite. That's the first point to understand at the outset.

Most homeowners are expecting quartz to be stain-proof which is why a stain is usually a big, head-spinning surprise.

Let’s take a look at why and how that is and the best tips for preventing and removing stains in quartz countertops.

Why Does a Quartz Countertop Stain?

You’ll learn exactly why and how a quartz countertop stains just below, but first a bit of background so you understand why consumers are confused about it all.

Quartz countertops are a man-made product referred to as “engineered stone” made by blending crushed quartz and various resins, polymers, and pigments. The resulting product is truly an excellent countertop material and a top choice for kitchen countertops.

But no material is perfect. All have faults. As a consumer buying countertops, you want to clearly know all the pros & cons upfront. Not as a surprise later after you’ve spent all that money.

So, a quartz countertop is made with real stone and has properties similar to granite but the resins and other man-made elements create unique properties that are different than granite. Some good, some bad.

The resins are what help make quartz countertops non-porous (good), but the resins are also what can be damaged by cleaners, chemicals, and heat (bad).

Quartz countertop manufacturers (Silestone, Cambria, Caesarsone, Zodiaq-Corian and others) all emphasize the "non-porous" nature of their product. And that’s fine. It’s true. But they let the consumer decide what that means.

BTW... quartz vs quartzite... these are not the same.

Here’s how that usually goes…

You read that granite is porous and must be sealed to prevent stains. This is generally true (but some granites are naturally stain-resistant and don't need sealing).

Then you read that quartz is non-porous and doesn’t need sealing. Hmmm….

The natural assumption is that “non-porous” means that quartz countertops cannot be stained. After all, how can it be stained if nothing can absorb.... right?

Most people get hung up thinking it’s impossible to stain quartz counters and none of the manufacturers do much to clarify.

In their defense, no quartz brand states their surface is "stain-proof". All clearly state that quartz is "stain-resistant".

The concept is a little misleading, but it's not false.

In truth, nothing will absorb.

So, how does a quartz countertop stain if nothing will absorb?

If we define "stain" as any discolored spot, then quartz will stain, but it doesn’t happen in the same way as a granite stain. The result is the same.... a stain, a spot, whatever... it looks crummy.

The mechanism of how a quartz countertop stains is different....

  • A traditional stain occurs when some substance absorbs creating a dark spot.

  • Quartz countertop stains occur due to a chemical reaction with the resins used to make the countertop.

  • A cleaner, chemical, food or drink discolors the resin.

  • The "stain" is usually a lighter white spot that appears bleached out (similar to marble etching)

  • Nothing absorbs

  • "Non-porosity" has nothing to do with it

Some foods and drinks (especially tea) can result in a traditional-looking dark stain.

Still, the mechanism is likely similar. Nothing is absorbing or very minimal. The tea is likely affecting or reacting with the resin used to bind the quartz together fixing the stain on the surface.

But typically, a quartz chemical stain is white due to bleaching of the resin.

White quartz countertops are
most vulnerable to stains from food. However, all quartz colors can be damaged by chemicals or cleaners.

Quartz Countertop Stain Removal Tips

With a granite stain applying a poultice usually removes it. This technique doesn’t work for quartz countertop stains. Nothing absorbs so there is nothing to draw out. It’s not a "stain" in the traditional sense, but more like chemical damage or a bleach mark.

Quartz Stain Removal Options:

  • Bar Keeper’s Friend is our favorite. It can remove many quartz countertop stains. Scrub with a nylon pad or brush. It doesn't always work since sometimes the discoloration is permanent.

    Note: quartz is highly scratch-resistant, but in rare cases, abrasives can dull quartz. Test first.

    Or try the non-abrasive Bon Ami (which may be less effective).

  • Glass Cleaner and a non-abrasive nylon scrub pad. This can sometimes work for mild surface stains.

  • Magic Eraser. Be careful and test first. It may work but also may cause further damage and dulling of the surface as it contains abrasives.

  • Diluted bleach (8 parts water / 1 part bleach) can work for some spots (WARNING: see below for additional info before using bleach).

  • Acetone (see more info below) can work for removing ink stains and gummy things on the surface.

Again, remember that the bleached-out stains where the resin is damaged from a chemical are likely permanent, and the above methods will not fix the spot or remove the stain. You can try but don’t hold out too much hope.

The above methods may work to remove surface stains from foods or other substances that have not damaged the resin. These are the darker spots or stains of the same color as the offending substance.

How to Remove Water Stains

Water stains are a different breed. These are from hard water buildup and leave a dull gray film.

Don't use CLR or Lime-Away as these are too acidic and will damage the resins and stain.

Regular cleaning methods won't work.

Use a hard water cleaner safe for quartz to remove hard water stains.

It’s also great as a regular shower cleaner to remove soap scum.

Proper Cleaning & Care of Quartz Countertops

Here's some good advice on choosing an everyday quartz countertop cleaner...

To avoid damage it's best to use cleaning products made for granite & quartz countertops. Too many common cleaners can permanently discolor quartz.

Since quartz counters are 93% quartz (a mineral in granite) it is safest to use products made for granite and stone. It won’t damage the resins.

Learn more about cleaning and polishing quartz countertops.

Most quartz manufacturers have the same basic care and cleaning recommendations.

Quartz Countertop Maintenance Advice:

Do NOT use...
  • Caustic soda, paint strippers, degreasers, oven-cleaners, are any high pH product.

  • Acids like hydrofluoric acid, CLR, Lime-Away or any low pH cleaner.

  • Abrasive cleaners or pads. Ironic since quartz shouldn't scratch. Note that an abrasive cleaner may be needed to remove a stain but can dull some brands of quartz. Test first.

Use with caution...
  • Bleach: Do not use bleach for regular cleaning. It can be diluted to clean a specific spot, but don't leave on the surface. Rinse well.

  • Acetone: Avoid prolonged contact of acetone on quartz countertops. Use only to remove a spot (like nail polish). Rinse well.

Sealing Quartz Countertops

Sealing won't prevent stains on quartz. It's a non-porous countertop material so the sealer can't absorb and isn't effective.

Also, some sealers may discolor the surface or create a haze.


All considered quartz is a great kitchen countertop. Very durable. So, quartz countertop stains are pretty rare but do happen.

Unfortunately, the resin gets damaged so quartz stains are often permanent.

All we can do is learn the weaknesses, take precautions, use proper care methods and cleaning products to avoid quartz countertop stains.

Sticky Residue on New Quartz Countertops
by: Anonymous

We just had quartz countertops installed, and I was doing the first clean with soap and water.

Left behind were small patches of glue residue. Like streaks of silicone. Mostly at the edges of the counters.

I got some of it off with goo be gone and persistent rubbing with a sponge.

I don’t know what else to do. I run my hand over my brand-new counters and feel this leftover stuck on stuff. I am so upset. Any suggestions?

==== Countertop Specialty comment:

First, you need to be careful what products you use on quartz countertops. Many cleaners and chemicals will bleach out the resins and dyes leaving permanent discoloration.

So, you shouldn't "just try something" like Goo Gone. Luckily it did not do any damage.

A solvent like acetone usually will remove sticky residues. Although, I believe Goo Gone is a solvent.

The problem is that some quartz countertops are sensitive to solvents which could cause discoloring.

Usually, if you use the solvent quickly, don't let it sit on the surface long, and then wash the area with soap and water using a solvent won't cause any problems.

So, since Goo Gone worked to remove some of the residue or at least improved the problem and you did not notice any discoloration from using it, then I'd continue using it.

But again, use it only for quick application and then wipe off and clean the area.

You could try acetone instead. It will evaporate quickly, but you still want to minimize contact time and wash the area.

And you should test it in an inconspicuous area first.

Also, contact the quartz countertop manufacturer for suggestions and the installer. It may not be their fault as the slab could have had these marks prior to installation, but likely it was something the installers did so make them deal with it.

Install Granite vs. Quartz?
by: Jay

So after reading all these questions about quartz staining and discoloration, wouldn't it make sense then to install granite instead?

I am about to change my 30-year-old countertops to quartz and now thinking granite would be more durable. What do you think? Thanks.

==== Countertop Specialty comment:

Engineered quartz is an excellent countertop surface and more durable than most other countertop materials.

However, in our opinion, granite countertops are better when all is considered.

Granite and quartz are at the top of the heap when it comes to durability, but no countertop is perfect. All have their strengths and weaknesses.

So, it is important to learn the proper cleaning and maintenance requirements for any surface to avoid damage.

Proponents of quartz countertops make a big deal about having to seal granite. But sealing granite is easy and many colors of granite don't even need sealing.

Darker granite colors are very dense, have a natural low-absorbency rate, and are basically stain-proof.

But without re-hashing all the pros and cons of granite vs. quartz suffice it to say that quartz countertops and granite have very similar levels of performance and durability.

But granite can take heat much better, will never get scratched or dulled from abrasives (while quartz definitely can) and most granite stains can be removed.

And the final important difference in durability...

As you learned from this article, quartz can be permanently damaged (sometimes rather easily) where damage to granite can almost always be repaired.

But again, the key is learning how to properly maintain the surface. Some materials will require a bit more care than others, but all require some level of proper maintenance.

Many don't take the time to do so and learn the hard way.

Find out first what you need to do, can and can't do. What will or won't cause damage.

If you do this, you likely won't have any problems at all with quartz, granite, or any other surface. The vast majority of homeowners that install quartz love it and don't have any problems.

Still, personally, I'd install granite over quartz because it does have the edge in overall durability and repairability.

How to match the color of quartz countertop slabs
by: Anonymous

Once a quartz countertop is installed, if you notice a slight difference in the color of the slabs, particularly at the seam, can this be repaired?

Is there a way to blend the two colors?

===== Countertop Specialty comment:

There is no way to change the color of a quartz countertop. So, no you cannot blend the colors of two slightly different slabs at the seam.

The color is baked into the product which is made of ground quartz set in a synthetic resin. And since quartz countertops are non-porous there isn't a way to dye or change the color.

You can change the color of natural stone like granite countertops. Well, you can make it darker by applying a color-enhancing sealer.

You can also dye granite and marble to change the color. This is very rarely done except with black granite countertops.

Black granite is dyed quite often, although, this is a fraudulent practice done by unscrupulous quarries selling slabs.

Dyeing black granite is done to make a grayish slab more black. But the dye used can cause maintenance issues that are not discovered until the granite is already installed.

It's a real problem in the industry but hard to detect.

But when it comes to quartz... no you cannot dye it or apply a color-enhancing sealer to change the color or match slabs that are slightly different colors.

Since quartz is man-made the color and pattern of slabs are very consistent and it is rare to have two slabs installed that are a different color.

However, there still can be slight variation in the color of quartz slabs so it is possible.

But usually, the fabricator will (or should) notice this difference and order a new set of slabs that are perfectly color-matched.

Old Candle Wick Stain on White Quartz
by: Lexy

While unpacking candles after moving, it seems that an old wick broke off one of them. When we picked it up, it disintegrated and left a gray stain on our white quartz countertop.

Regular dish soap and water didn't work and vinegar didn't help either. Any tips?

==== Countertop Specialty comment:

All the tips for cleaning stains on white quartz countertops and all quartz surfaces are indicated in detail in the article above.

The fact that it was a candle wick doesn't really change anything. You seem to have a surface stain so follow the advice and product recommendations provided above and you'll likely get the stain out.

Just first test any product you choose to use as some can leave slight dullness on some (but not all) quartz surfaces.

White quartz backsplash discolored within a month behind our oven
by: Kemanuel

Our white quartz in our new home has huge discoloration up the backsplash behind our oven.

Wondering what is best to get this out? Have tried soap and water to no avail?

Has this somehow been heat damaged? We always run the fan when the oven is on, however, I suspect my husband may have preheated the oven without the fan on.

Still rather disappointing that this should happen from using my oven.

==== Countertop Specialty comment:

Quartz countertops and surfaces can take a lot of heat, but excessive heat (like hot pans straight off the cooktop, or countertop appliances) can cause discoloration.

So, yes... it could be heat-damaged.

Also, white quartz is the most susceptible to staining and discoloration.

It could be repeated exposure to heat from the oven. It could be dirty exhaust from the oven.

Is there a pattern? Is it worse in one area vs. another.

Also, it depends on the "type" of discoloration. Is it a darker spot like a stain or a substance on the surface or more of a bleached out spot?

The first option to try is Bar Keeper’s Friend. This product has had the most success removing food stains and substances on quartz.

But test it first since it can scratch or dull some quartz surfaces.

You may also consider using Soft Scrub Oxi. It is less abrasive and many have reported success with this product. Again, be sure to test first.

Dulling from Bar Keeper's Friend on Silestone Quartz
by: Anonymous


I used Bar Keeper's Friend stain remover to remover on ring stains on my Silestone quartz countertop. In the past, it has not caused dulling but this time it unfortunately has.

Any thoughts on how to remedy this?

Thank you

==== Countertop Specialty comment:

as noted in this article above Bar Keeper's Friend can be very effective at removing surface stains on quartz countertops.

However, also noted, is that it is abrasive and on some quartz brands it may scratch and dull the surface so you should always test first.

Okay... but you've used BKF successfully before on this same Silestone quartz countertop without any dulling or scratching.

Unfortunately, I don't have a good answer for why it has scratched the surface now when it never did in the past.

Perhaps you used a different sponge... maybe more abrasive. Perhaps you used more product and scrubbed for a longer period or more vigorously.

Hard to say.

Repairing quartz countertops that have dull spots or scratches is possible in some cases.

Again, there are so many brands of quartz surfaces and even though all follow the same basic formula the end products tend to perform differently. Thus, some may scratch where others don't. Some may be repaired easily while others not so.

Your best option is to try to repolish the dulled areas using the Granite Polishing Kit".

Obviously, this kit is made for use on granite. Granite can always be repolished. However, due to the resins in quartz sometimes repolishing is not that successful.

But when the quartz surface is dull, you have 3 options:

1. Live with it
2. Replace it
3. Try to repolish it.

If you choose to use the product above be sure to test it out first on an inconspicuous area to see how the product works on the Silestone and make sure you'll get the results you want.

Residue or dull spot after removing ring stain
by: Anonymous

I had cup rings on my countertops that I could see only when I got down to eye level. I read to try baking soda and water and I used a magic eraser in a circular motion.

The rings came out, but I can see at eye level an area of where I cleaned. I went over with soap and water after and still there..... how do I get it out?

Thank you!!

==== Countertop Specialty comment:

The baking soda and water likely didn't do anything. This is a commonly recommended mixture that can work on surface stains as it forms a mildly abrasive cleaner.

Also, just FYI... it is suggested as a poultice recipe to remove stains in granite and other natural stone. It does not work for that. A chemical reagent other than water must be used to pull out a stain.

But quartz countertops are a man-made surface so spots and stains occur in a different manner than in granite. Likewise, the procedure to remove spots and stains in quartz counters is different.

What has likely occurred is that the Magic Eraser has removed the ring but has also scratched the quartz leaving a dull area that may look like a residue but is actually damage to the resin which binds the quartz minerals used to make the countertop.

As noted in the article above, a Magic Eraser can work really well to remove some surface stains and spots.

However, it can also scratch some quartz countertops leaving a slight dull area and should be used carefully.

All quartz countertops are made using basically the same procedure and recipe.

However, the quality of the finished product can vary a lot as the specific types of resins, materials, and procedures used differ from manufacturer to manufacturer. And many sort of "no-name" quartz countertops have appeared on the market in recent years.

This is why we advise to always test the use of a Magic Eraser or Bar Keeper's Friend or any product you intend to use on quartz. Quartz countertops can be damaged so it's prudent to be cautious.

Unfortunately, if you damage the resin (either with chemicals that discolor it or by using abrasives that scratch it) that damage is often permanent.

This Granite Polishing Kit can work in some cases to re-polish quartz dull areas. It will not polish out discolored or bleached out stains and spots from chemical damage.

And again, some methods work great on some quartz countertops but not as well or at all on others. There is no way to know ahead of time what will or won't work or may damage yours.

Here we are providing the best possible options for repairing damage to quartz counters, but always with the caveat that these methods will not always work in every case. Just the nature of quartz countertops coming from 20+ different manufacturers.

Also, one option is to simply learn to live with the damage.

So, if you choose to try a cleaning method, or use the Granite Polishing Kit, then first test it in a more hidden or covered area of the countertop.

Lysol and magazine = Silestone countertop stain
by: Holly

Lysol spray to disinfect Silestone counters. A magazine was left lying on the still-damp surface. And voila, a huge ink stain!

Tried everything, alcohol, hairspray, vinegar, baking soda with unbleached flour, bar keepers friend, and goo gone.

I got most out, but there's still a faint stain. Am I out of luck?

==== Countertop Specialty comment:

You may have removed as much of the ink stain as possible, but you might as well continue with repeated cleanings if you do not see any collateral damage from the cleaners.

Some cleaners will damage the resin used to make quartz countertops. Damage could include discoloration (lighter or bleached-out areas) or dullness from abrasive cleaners or pads.

Such damage is not common with Silestone countertops as Silestone makes a high-quality quartz countertop, but other brands of quartz can be inferior and get damaged much easier.

I'd stick with Bar Keeper’s Friend. It is the most consistently successful at removing quartz countertop stains.

Alcohol works well to remove ink stains too. So you may rotate cleanings with BKF and alcohol.

You could also try pure acetone. This is a solvent like alcohol, but Silestone warns against using acetone, so use it with caution and very limited surface contact.

Be very careful using solvents on quartz countertops. Most quartz countertops do not react well to solvents. The key is not letting any solvent remain on the surface for long.

Apply alcohol (or acetone) to a cloth (not directly to the quartz surface) and rub the stain vigorously for 15 seconds.

Then immediately and thoroughly wash and rinse the area with soap and water or a quality Quartz Countertop Cleaner.

Granite and marble cleaners are also the safest to use on quartz countertops. Get a Countertop Specialty coupon code to save on your order.

Experimenting with cleaners is risky on quartz and any countertop material.

Bleach, oven cleaners, drain cleaners, solvents, CLR, and Lime-Away can damage the surface.

Even acidic substances like fruit juice can cause lime etching on quartz if a spill is left to sit on the surface.

We've provided detailed guidelines in this article, but you should always test any product in a more hidden area first to ensure it will not damage the surface before using it for full-scale stain removal, etc.

LG countertops came with ring marks
by: C

We installed beautiful LG Soprano countertops and when the sun came in the window the next day, I noticed some large ring marks on the surface. I could not clean off so I called the fabricator.

He said they look like suction cup marks from the manufacturer when they move slabs. He tried to buff/polish them but that left marks that didn't match the rest of the surface.

LG did approve a claim for mfg defect and the fabricator will install for free. However, I will have to pay the plumber again for all of his work for sink/dishwasher and they may not be able to salvage my new big expensive sink.

This doesn't seem fair, but my bigger concern is going through the pain and expense to replace and I end up with circle marks again.

How often does this happen? How does this happen to a hard surface like quartz? No one can explain this to me. Also, can the entire surface just be buffed/polished on-site to get rid of marks? I don't know what to do. Thanks!

==== Countertop Specialty comment:

The suction cup marks are something we've heard about before from other readers. Why or how they occur is a bit of a mystery. It could be due to a type of coating on new quartz surfaces from some brands.

Yes, the mineral quartz is very hard and difficult to damage, but quartz countertops are also made with resins that are not hard and can react with other chemicals or be more easily damaged, discolored, stained, etc.

Ghost-like spots and marks or dullness can sometimes be polished out of a quartz countertop on-site, but discolorations, bleached out stains, and other damage are usually permanent on quartz countertops.

You can try Bar Keeper's Friend or acetone. BUT BUT BUT... test first in a small hidden area. Acetone can discolor some quartz and should not be allowed to dwell on the surface.

Apply it to a cloth and then rub the ghost rings quickly and immediately rinse and wash the area with hot soapy water.

Bar Keeper's Friend can often work wonders on quartz countertops, but again test it first.

We've seen different results on quartz from various manufacturers (not all are the same). Sometimes BKF can remove a stain, for instance, but it may cause a slight dull spot as it is abrasive and the resins may not handle that well.

Nail Polish Remover Stain on Quartz Kitchen Countertop
by: Anonymous

Before removing nail polish from my nails, I laid out a J-cloth on the counter. I think a small amount of polish remover seeped through to counter.

The shiny surface in small spot is gone. How to bring back shine there?

==== Countertop Specialty comment:

Likely you cannot get the shine back. Nail polish remover contains acetone which is a solvents can damage quartz countertops.

Quartz countertops can handle very short exposure to solvents which are helpful for some cleaning issues, but prolonged exposure will cause damage to the resins and dyes that are used to manufacture the countertops.

This is true of several different chemicals or cleaning products when used on quartz.

If you look closely you may see that the pieces of quartz are not damaged but the area surrounding the pieces of quartz is dull or discolored.

It's a long shot, but you may be able to repolish the area using a Granite Polishing Kit but this type of damage to quartz countertops is often permanent as the article above explains.

Using a Topical Stone Polish can improve the look and enhance the shine so it looks better, but it will not repair the dull spot.

Water Stains and Rings in Gray Quartz Countertops
by: Eileen8of9

We have a gray quartz counter which has rings on it.

Two look like they could be the size of a glass or a can.

The other two are rather large and we can't figure out what they can be from. We have tried Bar Keeper's Friend, alcohol, and vinegar.

Nothing is doing anything to eliminate the rings. Any advice?

==== Countertop Specialty comment:

Well, it depends if these are stains are from food or from some chemical damage.

Surface food stains can usually be removed using Bar Keeper’s Friend.

NOTE: Some brands of quartz WILL scratch and dull from abrasive cleaners so always test any cleaner first on quartz.

All quartz is supposed to be very scratch-resistant so a cleaner really should not dull the surface but different brands use different materials to make the quartz so scratches can happen with some brands.

Bar Keeper’s Friend soft cream is a less-abrasive option but may not be as effective removing quartz stains.

Food stains usually have a darker color.

Chemical damage "stains" have a bleached-out look or some type of discoloration. This type is permanent.

There could be one other reason and a third type of stain but it is pretty rare.

A third type quartz stain or spot may be due to a chemical film or glue-type residue remaining on the surface of the quartz countertop.

Many quartz countertop manufacturers apply plastic to the surface of the quartz slab to protect the surface during transport.

This film can leave a residue that may then react with foods and drinks to leave rings and spots that look more like ghost stains or somewhat like the clear etch mark rings or spots you get on marble.

Acetone may be effective in removing this type of residue and the ghost stains BUT USE CAUTION as some quartz countertops can be damaged by acetone and other solvents.

Use of acetone and solvents for cleaning can vary by brand of quartz countertop. Some can handle a quick cleaning using a solvent so long as the solvent does not remain on the surface and is thoroughly rinsed.

However, other brands may be damaged upon contact with acetone or solvents (along with many other types of chemicals as noted in the main article above.)

Check with your quartz countertop manufacturer for specifics.

Unfortunately, when Bar Keeper's Friend does not work to remove a spot or stain on quartz... it is usually due to chemical damage and is permanent.

But again, it could be some type of reaction with a left-over residue or chemical treatment on the quartz.

Is Bon Ami a good cleaner for quartz countertops?
by: R

We have a relatively new quartz counter but don't know the maker.

Recently a largish brown-outlined stain has appeared. I doubt we'd have spilled coffee without cleaning it up. I wonder if it could be water?

Scrubbing with elbow grease and the scruffy side of a sponge doesn't clean it. Dawn doesn't.

I was hesitant to use baking soda since it's abrasive.

So we tired Bon Ami. I am concerned that it might just scratch the finish even though it's not supposed to be that abrasive.

Is it ok to use the baking soda AND avoid abrading the finish? Or is one of your suggested materials preferable?

==== Countertop Specialty comment:

We've found that Bar Keeper’s Friend has the best success with removing stains in quartz countertops.

It is abrasive, but abrasive doesn't (should not) harm quartz countertops which are very hard and difficult to scratch like granite.

Bon Ami is not as abrasive as BKF, and like I said.... Bar Keeper's' Friend has proven to be the best for cleaning quartz stains.

Some stains or discolorations are permanent, but for any type of surface stain BKF is our best recommendation.

How To Seal a White Quartz Countertop?
by: Sonia

We recently installed white quartz countertops and right away we noticed everything stains them.

We use Vim and vinegar to get out stains as much as possible but sometimes it doesn't completely take the stain away as you can see a faint residue leftover.

Am I able to seal a quartz countertop?

Will this help protect them because right now they are so porous they pick up every little thing. Even leaning against the counter while I do dishes leaves scratches on the sides.

If I can seal, how do I do this? Can I do it myself or do I need to hire a pro? What products do you recommend to do this?

==== Countertop Specialty comment:

White quartz countertops have been very popular in recent years and quartz is an excellent countertop material, however, it does have some issues.

Quartz countertops are very stain-resistant but not stain-proof and white quartz countertops have proven to be the most susceptible to stains of all quartz colors.

It's hard to say exactly why this may be, but it must have something to do with a difference in the manufacturing technique needed to produce a white quartz surface vs. any other color or pattern of quartz countertop.

To answer your question about sealing quartz countertops...

No, you cannot seal quartz countertops. Or rather you could apply a sealer but it would not absorb into the countertop material as it must to work.

Also, it could potentially discolor the surface and/or leave a difficult-to-remove haze.

Another option would be to apply some type of permanent epoxy coating, but I would not recommend this as you trade one set of problems for another.

You'd then have an epoxy countertop to manage instead of a quartz countertops.

The best you can do is perfect your cleaning techniques to remove food stains, etc. I'd add one product to your arsenal though...

Bar Keeper’s Friend tends to have the most success removing quartz countertop stains. Try that.

Yellowing LG Quartz
by: Tomco

I would definitely call LG Corporate in Atlanta.

I speak with 19 years of experience and 100's of claims for two other brands.

I never worked for LG but IMO LG has always been a very professional stand up brand. Talk to the right people and you will get service.

Yellowing is not normal and a product that is 99.97% solid SHOULD BE IMPERVIOUS.

Nothing organic should stain it. If it stains there is a problem with the countertop material and the manufacturer needs to step up...

Be aware the warranty only covers the material not the removal or cost to have that material fabricated and installed...

That said L.G. should at minimum offer that after an LG company inspector inspects and finds that their product failed..

What I have found is most unhappy customer don't want to go through the pain and cost of having the tops replaced they just want the problem solved..

Normally when stains occur Bar Keeper’s Friend is going to handle them...

That your fabricator "polished" it tells me this was not a topical stain.

Again IMO breaking out polishing pads is a last resort effort. The fact that the area he polished is shinier than the rest of the material tells me he had to remove material from the surface.

That tells me the stain has penetrated into the material. That tells me the material is NOT 99.97% solid. IMO DEFECTIVE.

So what to do? Are you willing to shell out the money to have the countertop removed and fabricated?

If yes, ask then to supply the material. If not I'd try and negotiate an amount to at least make you feel they tried to make things right in a bad situation.

In small claims, I am pretty certain you would win but it's a hassle.

I again recommend that you communicate with LG in Atlanta where much of the material is made and get them to investigate the issue thoroughly. Hope they do you right...

Yellowing from wet kitchen towels
by: Anonymous

We had LG Viatera quartz installed in our kitchen about two years ago.

I noticed some yellowing right next to the kitchen sink.

LG sent their contractor to assess and repair. The contractor tried a few things including a hand polisher, but left without removing the yellowing spot. Instead, the polisher made it more shiny and visible.

LG said that it’s "abuse, or misuse" by having wet kitchen towels on the counter.

I never would have thought that water and wet kitchen towels in a kitchen would be considered "abuse and misuse".

We had Corian countertops for over 20 years and had absolutely no issues. I am super disappointed with quartz.

If anyone had any suggestions on how to remove the yellowing spit, please advise. Thank you.

remove sealer from quartz surface, mistakenly applied
by: Vida

Could you please tell me how to remove sealer from a quartz countertop?

The company applied it and I was left with water type marks all over.

They came back and used acetone and it removed some but not all, what do you recommend? Is there a product you sell I can buy to apply? Thank you, Vida

==== Countertop Specialty comment:

Well, using a solvent like acetone is the way to remove sealer residue on granite. BUT... using a solvent on quartz countertops can be risky. It can sometimes discolor the resin used to make the surface.

However, if acetone was used and no discoloration, then it's safe to continue using it. Just don't let it sit on the surface too long.

Pour some on, scrub, and then wipe clean using a granite countertop spray cleaner.

You may have to repeat this process several times.

Repeat....Disaster Silestone Quartz Countertops
by: Helen

I mentioned our messy white with color bits before and wondering if there is any way to have them redone. I absolutely hate them.

The dull darkening about 10 inches out on either side of the granite sink is ugly.

Home Depot rep has tried TWICE to fix them and failed.

Can’t afford on retirement $$ to replace them but is there some new method of covering them with epoxy or something similar? I’m bummed!!

==== Countertop Specialty comment:

Yeah, this situation is very unfortunate. Honestly, it's very hard to determine what the problem might be with the specs. Could be a manufacturing flaw.

Now with the darkening around the sink... again that is odd, but probably is chemical related. It may be that the glue used to secure the countertop has somehow stained the quartz.

This can happen with some granite and certain types of glue. I've never seen or heard of a case of glue stains with a quartz countertop but wouldn't rule it out particularly if the stain is more or less uniform around the sink.

The hole in this theory, though, is that glue was used to secure the entire countertop and these darkening is not seen anywhere else except around the sink.

Or it may have been a chemical used to clean up the glue after installing the sink and this chemical damaged the resin used to make the quartz countertop.

Usually, chemical stains in quartz are lighter in color... like a bleach mark, but any discoloring could be due to chemical exposure.

Possible Solutions

It is likely "possible" to cover the quartz with epoxy. Countertops are made with epoxy. But it's a messy job and you may not like the finished product either.

Re-polishing the quartz may be an option, but you need someone with experience and skill. Re-polishing quartz countertops is possible but not often done and not to many who do it.

Quartz Stains from Matches
by: Fred

We have white Quartz countertops with gray lines that run through them in our kitchen -- our designer convinced us to get them instead of marble and we've been very happy with them.

By mistake, I recently dropped the burned top of a match stick on the counters and it's created a blackish/gray stain. Wiping it away, only created more streaks so it's quite the mess.

Because of the gray streaks that run through the marble, it's not the worst of fates but it still riles me up every time I see it.

I want to get rid of it. What should I do? I've tried soapy water, window cleaner and Goo Gone. Nothing has worked. Ideas welcome.

==== Countertop Specialty comment:

It is possible that the match head burned the quartz surface and the spot is permanent.

But quartz can take heat pretty well so this is not likely.

Try scrubbing with Bar Keeper's Friend. It has the most success removing various spots on quartz that are not due to chemical bleaching.

by: Jenny

I use OxyClean to get wine and orange pepper stains off my white quartz countertops. So far it has gotten them all out with no ill effects.

I have a honed finish and it doesn't seem to cause any damage.

I make a paste with the powder and leave it on for a few minutes, scrub it a bit, then wipe it off and rinse.

It gets out the wine/pepper stains plus the coffee or tea film around the coffee maker that weren't as obvious.

I am always surprised how the paper towel turns slightly brown as it picks up the film I couldn't see. They sparkle white again. Try it. It may work for you.

It does stain
by: Anonymous

The Silestone countertop in my ensuite has a yellow stain under where the soap dish used to sit. I have tried everything suggested on this site as well as suggestions from the manufacturer.

My daughter in law has problems with her white Caesarstone. She has been able to get some of the stains out but is very sorry she went with quartz countertops.

I am in the process of building a new home and every place I have gone to look at granite people do their best to talk me into Quartz.

They act very surprised when I tell them mine has stained. I am told over and over that it is non-porous and shouldn't stain.

Well, sorry guys but it does! The granite in my kitchen is 15 years old and looks good as new.

Quartz for 15 years
by: Richard

We have had a Dark color Quartz countertop for 15 years with no regrets.

The manufacturer recommended greased lightning cleaner and that’s is all we’ve ever used. No chips no stains no dullness.

We’re remodeling soon to lighter colors but seriously after reading these stories "if it ain’t broke don’t fix it"!

Might be my motto. Sounds like lighter colors are problematic. As an aside our kitchen gets minimal natural lighting so perhaps that helped retain its color.

Bleach stains and quartz?
by: Tomco


You say you have a quartz countertop but you didn't mention the brand. Even then there is always the chance of bait and switch unless you are certain.

The best way to be certain (some brands have their name printed on the back side of the slab and you can see it from underneath ( if no sub top ) or when it is being installed).

If you never saw the brand name or don't know it call your installer. All legitimate brands have at minimum a 10 year warranty and then get a product representative out to inspect your countertop to confirm it is indeed their product and that it has failed.

I'm going out on a limb here but...I have been handling quartz warranty claims going on 19 years. Though not recommended, I have never had Clorox (or any brand of bleach for that matter) damage a quartz material we have sold (multiple brands) not saying it didn't but it leads me to believe either it wasn't bleach or you have an off brand product that is not real quartz.

I just recently inspected material installed in about 300 hotel bathrooms that was failing...it wasn't quartz...it was engineered marble sold as quartz...YIKES!

Based upon your claim I am going to test some brands with bleach and see if I can get them to discolor and report back ...I've tested with a lot of solutions but never bleach...

BTW how long was the material exposed to the bleach?

Clorox stain on quartz countertop
by: Mary Lou

My husband spilled some clorox on our new quartz countertop it discolored it. What can i do? Help!

==== Countertop Specialty comment:

Read the article above. Clorox bleach stains are usually permanent. The resins and pigments used in making quartz countertops get bleached out and there's no way to restore that color.

You can try using Bar Keeper's Friend, but I wouldn't get your hopes up.

Quartz countertops stain but most can be removed

Shadow rings all over Caesarstone countertops
by: Anonymous

I have 9 month old Caesarstone Raven and we have over a dozen ring marks from glasses already. They seem to be just under the surface and show up like darker shadows.

The installation company has tried several products to remove (abrasive stone products, acetone) and just ended up dulling the surface with ring marks still visible in certain light.

I'm thinking that wine and spirits are reacting with the resin and then it's permanent. However, we also have rings from a plastic hand soap bottle containing a gentle, green product, and lots of water spots around the sinks.

Any suggestions on how to remedy? I've thought of pouring wine on the whole counter and letting it sit!

I'm using my quartz counters the same way I used previous granite ones and after 10 years, the granite ones still looked brand new!

Very unhappy with quartz! It seems ridiculous that I have to treat them like I would fine wood furniture and have everyone use coasters or put on a table cloth to cover my island when entertaining.

==== Countertop Specialty comment:

Dark rings or spots are usually from food stains like tea or coffee. Try Bar Keeper's Friend.

Just because a product is "green" doesn't mean it cannot do damage. Vinegar is an eco-friendly green product but it is also acidic and can damage many materials like marble countertops for instance.

Soaps are generally not an issue, but there are so many who's to say one won't cause a problem with quartz countertops.

Acetone can be used sparingly as a quartz cleaner. But should not let it sit on the surface long, rinse really well, and only use when really needed.

Yes, rings could be permanent.

Water spots around the sink and faucet could be hard water stains. Use this Hard Water Remover which is safe on quartz counters.

Help - no shine
by: 10isslvr

I had a stain, and used Clorox bleach gel on it like I do everything. The stain is out, but now also the shine. Anyway to get that shine back? Thank you!

==== Countertop Specialty comment:

Why would you use bleach on "everything". Every material is different and bleach can damage many things including quartz countertops.

A very dilute solution of bleach can be used when really needed but should be avoided and cannot let it sit long on a quartz surface.

The dullness is likely permanent. Call a stone restoration pro in your area that has experience with quartz. May be able to repolish it, but likely not.

Silicone stains from installation?
by: Beth

Just had MSI matte finish dark countertops installed. There are dark wipe marks where the installers used acetone to wipe away the excess silicone for sealing the sink.

I’ve tried everything to get it off - Bar Keepers Friend, Simple Green, stone and tile cleaner, acetone...

I’m just sick about it! I was prepared to be cleaning fingerprints off of this surface - we were warned that the "suede" finish shows more of the greasy type marks, but this is from the install! Installer hasn’t been much help...

===== Countertop Specialty comment:

Solvents like acetone can sometimes discolor or cause problems with quartz countertops.

Usually, limited use of acetone is not a problem. In other words, using a little acetone to clean off some gunk and then immediately wiping the area clean won't cause any damage.

But if a lot of acetone is used and left to evaporate, then some quartz surfaces may not react well to that.

Not saying this is for sure what has happened but could be.

Or possibly silicone residue not completely wiped away.

And it 's the same with all surfaces. All countertop materials have specific care requirements including certain products or chemicals that should not be used on that material.

Streaks on New Quartz Countertops
by: Janet

I just installed quartz in my kitchen. It is beautiful but there are several marks and streaks that I can not remove especially when the sun comes in my kitchen.

The marks were there when the counter was installed. The contractors thought the the marks could be removed.

They tried but failed. They said these are natural
imbedded defects that sometime occur.

Bar Keeper friend and Mr. Clean sponge for the win!
by: Anonymous

I have Hanstone "marble" in my baths. My adult very messy kids share the upstairs bath that I rarely go into because, well they are kind of gross.

Today I cleaned said gross bath and found a BLUE stain on the countertop. I about lost it!

Thanks to the info here, I was successful in removing the spot and will not go to prison for murdering the boy who is about to turn 21 who was responsible. :D

I was very gentle to not remove the sheen and it worked with a couple applications.

I have no idea how long the stain has been there, so very grateful it was effective.

The funny thing is I just bought the bar keepers friend to remove hard water spots in this exact same manner from my chrome fixtures in my shower. Two problems solve with ease!!!

Do not purchase white quartz
by: Anonymous

I was really happy with my white countertops they looked amazing until you touch them. I have only had them for 3 months and I highly regret purchasing them.

Everything stains them, I have grayish-blackish marks everywhere and also brownish stains. I do not drag anything across the countertops to have these marks and I knew about the heat-stains so I have always used a hot pot pad when I place my coffee mug or even a plate with food.

I have to place silicon mats all over the countertops and make sure my pants do not brush the edges of the stone so it doesn't get scratched or stained. I think purchasing plain white quartz has been the biggest mistake I have made.

I'm so frustrated and unhappy since I love to cook an entertain. I think it was very shady of the salesperson not to warn me off this big issue since I could have chosen a different color since my budget was big.

Also, I have no kids and I'm extremely OCD, so if you are not very clean or a careful person DO NOT get WHITE.

Ugly dark brown wrktop
by: Someone

My dark brown quartz top looks terrible. The sink area is covered in pale stains which make it look filthy.

I live in a hard water area (London) and water does this.

If you don’t use you sink that’s fine. It also scorches very easily.

And the edges chip if you drop something on them.

Nothing removes hard water stains. I’ve trued everything. A very expensive mistake indeed. I have to live with it.

Oven Pride issue
by: Tomco

Definitely a very stong cleaner that contains chemicals that can etch quartz countertops... It is not stained it is etched... probably looks lighter / whiter and has lost it's shine... This is a very difficult fix if fixable at all..

It may be worth contacting Stone Forensics https://www.stoneforensics.com/ and seeing if they have a trained restoration guy in your area...

The guy that owns the company developed a system that provides the best results I've seen. It may be savable but only a pro that knows how to do this type of surface polishing can tell you if it is possible or not....

Sorry that you had this issue....Quartz is tough and most common household cleaners have no effect on it.

I have used Easy Off oven cleaner in the past to remove stubborn food stains ...but Easy Off doesn't have the harsh chemicals that Oven Pride has...This is the first I have heard of this product and I will make my customers and the industry aware of the issue...not good...

The only household product I warned people about not letting get on their quartz countertop was Paint Strippers because of the Methylene Chloride in them will etch like Oven Pride did to yours...

It usually isn't an instant thing if you wipe it up quickly and dilute with water but if it sits full strength for several minutes or more you are most likely going to have etch marks....

Love my Quartz countertops
by: Mary Kay

I purchased Summerhill Cambria Quartz countertops for my kitchen. I can't say enough about how beautiful and durable they are.

A friend did her kitchen at the same time and went to a big box store and has had nothing but problems.

As most people are aware, big box retailers are builder grade products; on the good/better/best scale, they are at the lower end, thus the deep discount pricing.

I would highly recommend Quartz based on my experience. Best advise I got, if you wouldn't put it on your face, don't put it on your Quartz...Same for cleaning.

Most common stains are easily removed

I have removed many stains on my granite top with just baking soda. Tougher stains come off with a mixture of baking soda and white vinegar or lemon.

Bad discolouration from turmeric gone
by: Antonia

I had some turmeric powder (bright yellow) that got onto my white, newly installed quartz countertop.

I didn't notice it at night but, during the day, it was bright yellow.

I wiped it with warm water and spread it over a foot-wide area. It stained and soap and granite cleaner would not remove it.

It looked awful. I then used the non-scratching "scouring" silver e-cloth with the Miracle O2 pet urine stain remover, which is apparently safe for every surface and has been great on my hardwood floors.

It literally vanished within a minute, leaving the surface as shiny and white as before. I went over it with soap and water again just to remove all traces of the solution.

Sharpie pen stain on white quartz
by: Cindy Hartley

So I recently had a gorgeous white, silver-flecked quartz countertop installed in my kitchen. Long story short, my nephew who's a grad student in biology was using a red permanent Sharpie pen to trace a pattern on shelf paper laid out on my new counter.

Ack!! We quickly saw there were thin red bits of lines on my counter.

We tried wiping with a soapy sponge, to no avail. Tears came to my eyes.

Then my science nerd nephew asked if I had rubbing alcohol, because this is a solvent for Sharpie marks.

Your readers are probably all gasping out there, but I was desperate and clueless. So we rubbed a stiff sponge dampened with alcohol on the stains.

We noticed slight fading of the stains, so we poured a little alcohol on the stains, let it set for a few seconds, vigorously rubbed again, and voila!

To my amazement, but not my nephew's, the stains came out 100%.

My counters were not scratched, dulled, or anything bad. They look perfect in any light, from any angle.

Tears again came to my eyes! I'm sure alcohol is a forbidden cleanser, but I'm just telling my story for anyone who has tried every approved cleanser for permanent marker stains without success. Alcohol might work for you, as a last, desperate resort.

==== Countertop Specialty comment:

Alcohol can be used sparingly to clean a specific stain but should not be allowed to sit long. Apply the alcohol, scrub, remove and clean with soapy hot water.

Cleaning stains from Quartz (Caesarstone)
by: skiking

After reading all of the comments and recommendations, this is what worked for me.

I have Caesarstone quartz countertops in my kitchen. I notice a circular ring stain on it this am.

I mixed a baking soda/ water paste solution and added about 6-8 drops of liquid dish soap.

I applied it heavily on the stain and then covered it with saran wrap and let it sit about 10 - 15 mins. I then removed the saran wrap and rubbed aggressively with a non-scratch sponge and it removed the stain.

Wiped clean with water, dried and polished with micro-fiber towel.

Just installed Quartz in Kitchen...
by: Tracy

We just installed Caesarstone quartz countertops in a medium gray.

We used brown paper and blue painters tape on the counter top to protect it while we grouted the backsplash.

After we took the paper and tape off, there's darker marks on the counter top where the tape was.

Can't get it to come off. Doesn't feel sticky at all, just darker in the area where the tape was.

Also looks like oily fingerprints and smudges on the counter top that won't come off either.

Pretty disappointed in quartz if this is how it's going to be!! Anybody else have this happen with tape?

Regarding... Silestone bought from Home Depot with strange marks showing up around sink
by: Tomco

Hi Helen

Your situation sounds strange and I am very surprised HD is not making sure your problem gets resolved. I am assuming you are dealing with the fabrication company that did the installation...

In the Home Depot network there are some fantastic companies that do their work and some not so fantastic companies.

The person that came to inspect the problems level of experience may also play into why your situation has not been resolved.

To be clear, I don't work for Home Depot or Silestone.

I actually import quartz from Asia so I am a competitor. That said I have the highest respect for both companies and Silestone, though not perfect, puts out an extremely high-quality product.

I've been involved in the manufacturing of quartz for over 15 years inspected 100's of claims and seen 1000's of quartz countertops installed.

With quartz countertops visual defects ( aside from chips, scratches and cracks) generally don't just appear after the fact, they are either there when it is manufactured or they are not.

In your case, something is discoloring after the fact and the first thing that comes to mind to me is that probably what you are seeing discolor is not the quartz but something topical on the quartz.

This happens with white quartz sometimes because when they are cleaning up they don't see the residual white glue or caulking.

I suspect either a very thin layer of the caulking they used when they installed the sink or the glue they used to seam the quartz was left where you are seeing the problem.

Try taking a window cleaning razor blade and with the blade horizontal to the material see if you can "shave" any residue off the problem area.

If any white residue comes up, that is your problem. If it's just quartz there, you won't get any residue and then you have a seriously strange and rare situation that I'd have to see to comment further on.

"If" the blade test comes up negative.... first get your facts together with pictures and go visit the HD store manager.

If he does not provide satisfaction, call corporate... Silestone does have a 15 year warranty against manufacturing defects and Home Depot has a strong customer service commitment....Good Luck!

Disaster countertop
by: Helen

We purchased new cabinets and highly recommended Silestone Quartz countertops from Home Depot.

I chose white with tiny specks of colors. We noticed a tan color begin to appear on the right side of the sink.

Someone was sent out TWICE to look at it and determined it was a flaw not stain. The company refused to belief it and refused to make it right.

It now appears on the other side of the sink as though the discoloration runs through where the sink was cut.

Never ever would we purchase this product again... we still have the ugly expensive countertop...and never again will we trust Home Depot.

Quartz breaks easily/Wouldn't buy again
by: Jennifer Goetz

I bought quartz because I was told that it is the hardest material out there and you don't have to seal it and basically it was maintenance free.

Within the first week, I dropped a glass bowl of chicken soup on the counter.

The bowl didn't break but it took a quarter inch gouge out of my top. The company came and after a 2nd try was able to fix it 90%.

Tonight I was putting a dish in the dishwasher and it hit the corner of the counter. The dish was fine, but the counter got a small chip.

I love to have people stay in my home and now I would be afraid to let them stay here without me for fear that they will do something to destroy my counters as they are SOOOOO delicate. I say, BRING BACK FORMICA!!!!!

18-Year Stone Restoration Technician
by: Jess

There's a DIY show called Deconstruction. One of the episodes was about most hard surfaces you can find. Granite out performs every other surface.

If you use the right sealer, it will never stain, get burnt, scratch, or etch. The only challenging stain granite can get is from oils soaking in.

In order of stain severity, this list will solve almost every problem: soapy water, a brand new razor blade, Magic Eraser, Bar Keepers Friend (0000 Steel Wool very lightly).

After 18 years of restoring all things stone, I've come across many types of man-made products. Granite is the best surface for kitchens hands down.

Oil Stain Removal Help!

My quartz countertop is so new. It's 2 months old. I have a stain on it from mink oil.

I was sitting at my peninsula oiling a leather jacket and accidently got some on my countertop.

I cleaned it up and noticed the next day that it had left a dark mark on my nearly black counter top. Any help would be greatly appreciated.

===== Countertop Specialty comment:

Well, it is difficult to truly stain quartz countertops, but various discolorations can occur.

Cleaning with Bar Keeper's Friend and a non-abrasive scrub pad is likely your best bet. This won't remove every blemish or spot on quartz, but it is typically the most successful.

How Quartz Stains
by: Mike

Quartz countertops, as a general rule, are 93% quartz particulate and 7 % resin which acts like a binder to hold the quartz particulate together.

Most stains are chemical burns that "etch" the resin or cause the resin to shrink/expand and thereby allowing the "stain" product to enter the space between the resin and quartz.

Heat also causes the same problem. However, most heat burns are essentially causing the resin to dull or look hazy.

Our Quartz Never Stained....
by: Anonymous

From a 16+ year industry person... A "stain" that can't be removed was always a turn-off. People worry they've made a mistake after spending lots of money.

We sold solid-surface (Corian-like) along with both granite & quartz countertops.

Oddly it was easier to sell solid surface. People wanted to know what could go wrong with each surface and whether or not there was an easy remedy to the problem and that's how most made their decision.

Solid surface scratched easily but if we shared that upfront and they knew the resurfacing process would ultimately remove any mishaps then they were OK with it.

All surfaces have their unique set of surprise issues, however, as long as the issues are solvable then it had the advantage.

We never had any of our quartz surface installations stain or scorch but I have heard of both happening... if there is no remedy than it's permanent damage in the mind of the homeowner.

Discoloration Around All Edges of Quartz Countertop
by: Anonymous

I had a beautiful natural white quartz with green striation. All the cut sides of the countertop (cooktop, sink, beveled areas) have turned grey.

The edge is slowing moving inward. I suspect I will soon have grey quartz. I mainly clean it with soap and water and occasionally with quartz cleaner. Anyone else with this problem? What is causing it

==== Countertop Specialty comment:

Typically, this type of stain presentation is caused by the adhesive used during installation.

Sometimes certain chemicals are used to help the glue dry faster, etc. These chemicals react with some types of stone.

This problem is most commonly seen with new granite installations and rarely with other surface materials. Of course, quartz countertops contain elements of natural stone so theoretically this problem can occur with quartz as well.

If this is what happened, then it is not a problem with the quartz, but with the method of installation.

Removal of these glue stains is difficult but possible with granite. Unfortunately, stains in quartz countertops can be permanent and the methods that can be used on granite do not apply to quartz since it could cause other damage to quartz.

Contact the manufacturer and installer.

Discolouration/damage to Quartz countertop
by: Anonymous

Help! We have moved into a brand new house with a brown Quartz countertop. Within a couple of months, there is discolouration of the Quartz around the sink and under the draining area.

The discolouration is like a pale speckling so the Quartz appears paler and more shiny/sparkly in these areas. The surface is still shiny so the discolouration seems to be under the surface.

We have been careful to wipe around the sink, although not religiously wiped under the draining rack, which is generally used for draining glasses only.

We are in a hard water area and the stains appeared at this time and although we now have a water softener installed, I couldn't be sure this has stopped additional staining.

We have tried 'Unika' granite and Quartz cleaner which came recommended from elsewhere but this made no difference.

Any help much appreciated.

==== Countertop Specialty comment:

That it appears "more" shiny is odd, but what you describe is almost certainly hard water buildup.

Hard water deposits are minerals left behind after water evaporates forming a whitish or yellowish film that can be crusty. Happens almost exclusively around sinks, faucets, and in showers.

Perhaps your water contains some mineral that is sparkly as well.

Cleaning can be difficult. Hard water films are tenacious and a regular cleaner won't touch it. You need a cleaner specifically for hard water, but one that is non-damaging to quartz. Most cleaners of this type (like CLR) are highly acidic.

You'll want to use this Hard Water / Soap Film cleaner made for use on marble, granite and quartz countertops.

Etched area on your dark quartz countertop
by: Tomco


Unfortunately it sounds like the harsh cleaner has etched the surface..

The sharpie will help make it less obvious but it will not shine like it did.

Generally it is taboo to try and surface polish any stone countertop because it is nearly impossible to match the factory finish. Most often you will be able to see that sheen is different.

That said in your dependent on where the undesirable damage has occurred it may be worth having a stone professional come out and polish out the etched area.

Understand, it will look much better but you will be able to tell it has been repaired. It will look better than the sharpie fix but it will not look brand new.

Any decent stone guy can make it look better than it is...how much better is contingent on that particular persons experience is with what we call surface polishing.

There is a gentleman named Fred Hueston who developed a method to get the most optimum end results. He and his counterparts teach fabricators how to do surface polishing. You could contact his company and see if there is a trained expert in your area...you'll pay more most likely but get the best end result.

Not sure what someone would charge but I'd be prepared to at minimum $200 maybe more. Once you find a person that will do it you can decide if you can live with the sharpie fix or want it fixed better.

OR...you could just get new tops. The quartz color development has made leaps and bounds in the last 10 years.

Some amazing new offerings have come up especially since Cambria introduced their "Natural looking Collection" of colors in 2011. Amazing options today...

Good Luck whatever you choose to do!

Bleached spots on dark quartz countertop?
by: Donna

We have a 11+ year old, dark blue/gray "engineered quartz" counter top. I can't remember the brand. Up until this point, we have had no real issues with it.

This weekend, our cleaning lady set a bottle of some (industrial quality) cleaning solvent on it and it apparently dripped. I thought it was just a residue, but when I went to remove it, there are now (obvious) white spots on the counter.

Is this a situation that can be remedied, or should I just invest in a navy blue Sharpie marker?! We have dulling, etc, but that isn't as bothersome to me as the bleached areas. Any advice is appreciated!

==== Countertop Specialty comment:

Yes, the white discolored spots are chemical damage to the quartz countertop. Some chemicals can affect the colored resins in the quartz resulting in the bleached spots.

While quartz countertops do not stain in the traditional sense (substance absorbing) like granite or natural stone might, they are sensitive to some cleaners, etc. and can be discolored or stained in this manner.

Typically, chemical damage stains to quartz countertops are permanent.

For this reason we recommend that quartz countertops should be cleaned with the same type of products used to clean granite & marble countertops.

Rust Stain out of Quartz
by: Rita

Our white quartz countertop ended up with a rust stain from one of my husband's tools.

Lime Away toilet gel got it out and did not harm the counter. It took several hours. I put it on with a Qtip and changed the solution three times to keep the solution fresh as it reacted with the rust.

==== Countertop Specialty comment:

Lime Away is a very harsh and potent chemical and typically should not be used on any natural stone or stone-based surfaces like quartz countertops, so always proceed with caution.

Glad it worked for you in this case, though.

Water mark?
by: semperflorens

My husband and I have had our white Quartz countertops for almost a year with no staining whatsoever.

Today, I left a glass of tepid water on the counter and came back to a grey ring that I cannot get rid of.

We have had countless weeping glasses of water, tea, coffee, soda, etc. on this counter without problem. Why this ring?? How do I get rid of it?

=== Countertop Specialty comment:

White is the quartz countertop color most sensitive to staining, etc. Granted, you've had no problems previously.

Your best bet is to try Bar Keeper's Friend. This is successful in many quartz stain cases, but sometimes discolorations and stains on quartz are permanent.

My poor quartz worktop
by: My poor Quartz worktop

In reply to the suggestion I use hard water stain remover, the stain us not superficial. The brown top has turned pale beneath the surface. It is definitely a chemical reaction.

It is all around the draining area and looks terrible. I have tried everything. It is beautifully shiny and polished but still pale.

Also, I should add that once a China dish fell out of the cupboard above and broke the edge of the counter! Not at all impressed. If it had been a cast iron pan I might have understood!

Get granite, wood or melamine. I'm stuck with this expensive top that never looks clean.

Black marks on white quartz
by: Sara P.

My husband and I just remodeled and decided on white quartz countertops in the kitchen. We ALMOST love them... except we are very frustrated by black scuff marks!

One specific example is black marks left from the little rubber "feet" on most small appliances (i.e. food processor, blender). We do not keep the small appliances on the counters, only bring them out when in use.

On the other hand, food and water stains have not been an issue (yay!).

I've used soapy water, non-abrasive scrub pads, bar keepers friend, and A LOT of elbow grease to try to remove these marks. Any other suggestions will be happily received. Thanks so much!

===== Countertop Specialty comment:

That's a bit of a mystery why they are occurring and why so difficult to remove. Would seem to be something right on the surface.

BKF is usually a good bet for cleaning tricky spots on quartz countertops.

Maybe consider replacing the black rubber feet with clear rubber feet. Or placing the appliances on some other tray or surface.

Not ideal but better than the black marks.

Water spots - discolouration
by: My poor Quartz worktop

I have had my dark brown Quartz worktop for four years and it now looks terrible around the sink area. I contacted the manufacturer who said (on seeing my attached photo), that they were water marks and so couldn't be erased.

This is on the routed drainer area! They said standing water would do that. Am I supposed to dry the dishes before I put them to drain? It was a very expensive purchase for me and I'm heartbroken over my scruffy looking worktop.

I'm at a loss as to what to do about it as the manufacturers are not interested. DO NOT USE QUARTZ IN HARD WATER AREAS LIKE LONDON!

==== Countertop Specialty comment:

Yes, most likely this is just hard water build-up which can be very difficult to remove, but not impossible. You just need the proper cleaner.

It may take a couple rounds of cleaning, but using this Hard Water Stain Remover should do the trick for you.

by: Quartz Surfaces

Well you learn something new every day.

Others have mentioned using a "Magic Eraser" to remove stains on quartz.

I have never used a magic eraser but assumed it was a chemical based cleaner...just found out after googling per the poster saying his top was dulled by one.....IT IS NOT! it is a melamine sandpaper. YIKES!

In my earlier post when I explain how to remove stains I mention using a "WHITE" "NON ABRASIVE" Scotch brite pad.

The red and green ones contain aluminum oxide and can dull your countertop surfaces.

Not sure what the abrasive is in the melamine sandpaper of the Magic Eraser but just knowing it is an abrasive and not a chemical I would never recommend it for cleaning a quartz material.

409, Bar Keepers Friend, and most gentle household cleaners should remove most stains.

===== Countertop Specialty comment:

Appreciate your insights Tomco. For a long time Magic Eraser seemed to work well in some (but not all cases) of stains on quartz countertops. Rarely if ever a report of damage.

However, in recent months we've received several reports of magic eraser causing spots or damage. Possibly a change in product chemicals / manufacturing.

In the past we've suggested to "try" a Magic Eraser... sometimes helpful, but we agree with you Tomco... should not use a Magic Eraser anymore on quartz countertops. Too risky.

Damage by Magic Eraser
by: Anonymous

Well I meant that the use of magic eraser left dull stain look in several spots on the quartz countertop.

Could it be the case (that magic eraser damaged the countertop)?

Maybe the glossy finish is damaged at these spots? If so can it be repaired?

==== Countertop Specialty comment:

Yes, it is possible that a Magic Eraser damaged the quartz surface.

Magic Eraser is abrasive and contains other chemicals. It has proven useful for removing some stains on quartz countertops, but should be used with caution.

Bar Keeper's Friend is a safer bet to try first.

Stains by Magic Eraser on Quartz Countertops
by: Anonymous


I have used the Magic Eraser on my white quartz countertop and it left big stains on it. Should it happen? How can it be repaired?

==== Countertop Specialty comment:

White quartz countertops are the most troublesome quartz color maintenance-wise. They stain the easiest and the most difficult to remove.

Quartz in general can be tricky once stained or discolored. Some solutions work in some cases and not in others.

Magic Eraser has worked well in the past on some stains in quartz countertops, but then products can change as well. It is abrasive so this may have caused a problem.

Bar Keeper's Friend is often helpful. Also, you may try Shout Stain Remover.

Also, always test in small inconspicuous area prior to using any chemical or product on quartz or any surface.

Problems with Quartz White Spot
by: Anonymous

We have had two different problems with our Dupont Zodiac quartz countertop purchased from Lowe's.

First, we have a white spot on our dark brown countertop where a toaster oven was sitting.

Neither Lowe's nor Dupont would repair it. The customer service person at Dupont said we should have had our toaster oven on a hot pad.

Next, we have another bad spot where battery acid leaked on the countertop.

We purchased this countertop from Lowe's because the sales person told us that the Dupont Zodiac was trouble free.

Sadly, we were misinformed. Also, we were surprised and angered that neither Lowe's nor Dupont stood behind their product.

===== Countertop Specialty comment:

Well, I'm sorry your countertop is damaged, but I agree with Dupont and Lowes a bit on this one. I don't think you were misinformed.

Quartz countertops are very durable and low-maintenance compared to most other countertop materials, but every single type of countertop material out there can be damaged.

When used under normal conditions, quartz countertops are rather "trouble free".... meaning care and cleaning is simple and easy.

To me "trouble-free" doesn't mean totally indestructible.

You spilled battery acid on the countertop!!

And you thought this wouldn't cause any damage? Battery acid will damage almost anything, so I'd agree... this was one is on you.

Remember, these are kitchen countertops. They are designed to be used as such. Not as garage work benches.

They can be damaged by some household chemicals, but when used as intended and cared for with reasonable caution, then very few have any maintenance problems with quartz countertops.

Quartz can stand up to heat reasonably well, but expecting it to stand up to long-term exposure to rather intense heat of a toaster oven is over-optimistic.

Granite is probably the only material that could take that, but even granite could crack from thermal shock in this scenario.

Also, I think it is reasonable for Dupont / Zodiac to expect that purchasers will take the time to learn the proper care and maintenance. Info is readily available on their website and others.

Quartz countertops - no regrets or disappointment!
by: Jan

I've had white quartz for three years with no issues. Love, love, love it!

My only challenge was having recently spilled hot peanut oil on it but followed suggestion in above post to try a magic eraser. Worked perfectly! Thank you!

Perhaps there are different qualities of quartz? Don't let the negative comments here scare you away from quartz. It's a beautiful, low maintenance option to granite especially if you are looking to contrast dark cabinetry.

==== CTS comment:

Agreed! Quartz surfaces are an excellent choice, although, basically all the same regardless of brand (except colors & patterns vary of course).

Quartz countertops are not perfect... but neither is any other countertop material.

So, yes... put such "negative" comments regarding problems with quartz and/or experiences of others into perspective.

Every type of material has potential weakness(es) that can be viewed as "negative". It isn't a reason not to buy. Every single typo of countertop material is susceptible to some problem that you need to guard against... that's all.

It's just important to be aware of the possible issues you may encounter as a consumer (which is why all comments are helpful) in order to weigh the pros and cons of each material type and choose which is best for you.

Buying quartz countertops vs. granite
by: Anonymous

I don't own a Quartz countertop yet, but will in a few months. I've been researching which countertop to get for a few years now.

This is the first website where I've seen a lot of negative comments on Quartz.

Makes me think Quartz is edging up or has gone beyond sales of Granite?

Maybe those complaining about Quartz are bogus complaints coming from competition. I've seen that happen with various products on different websites.

I will be ordering Cambria, just purchased the 12x12 pieces yesterday so I can choose a color.

Thanks to Tomco for stating the facts :)

Only complaints I have seen for Quartz were those that abused it by using bleach or other caustic products.

One person said she put bleach on her Quartz and let it sit a few hours and her stain keeps coming back, duh, I wouldn't let bleach sit on any surface for hours.

==== Countertop Specialty reply:

Thanks for your comments! And we also appreciate Tomco's thoughtful additions.

Read through this site you’ll note we consistently praise and recommend quartz countertops as a top choice for countertops… we don't have an agenda for either.

Our site is dedicated to the consumer, so we aim to tell the truth minus any marketing, which we all know can sometimes be a bit misleading.

The questions/complaints here are from real people with real experiences with quartz countertops.

You'll read similar questions/complaints for granite and marble too.

There is no conspiracy from "granite". Quartz is in competition with granite... not the other way around.

The profit model and existence of several companies depend on convincing the consumer to buy quartz instead of granite. Not the same for granite.

No company (or small group of companies) "makes" granite. It is quarried and fabricated all over the world and the same fabricators that install granite countertops usually will also install quartz countertops.

There aren’t concentrated interests in granite attempting to push back against quartz.

The opposite is true though. Quartz can only survive by marginalizing granite.

Statements such as… "granite stains easy and must be sealed every six months" really stretch the truth.

Many granite colors should be sealed, but it’s a rare granite that needs it every six months. Most need it every 3-6 YEARS… some 8-10… and many granites NEVER need sealing, are non-absorbent and virtually stain-proof.

Same deal with granite harboring bacteria… false. Several studies show both granite/quartz are basically identical.

You correctly assume that you shouldn’t use bleach on quartz, but many are surprised at spots or stains on quartz.

Why?.... because they thought it’s "stain-proof". Why? ...because marketing makes a big point out of quartz being non-porous, etc.

Again, quartz is a fantastic surface.... noting potential issues isn't an argument against it. No surface is perfect. It just helps you make an informed decision.

Annonymous postings from "pro experience"
by: Quartz Surfaces

Amazing how someone with 8 years of "experience" can put out such terrible misinformation.

Obviously all the people here who are happy with their Quartz countertops must be wrong ..they just don't know it...

Yes you should not put a hot pot on Quartz or for that matter granite..it's called thermal expansion and it can cause things to crack at their weakest point.

Placing a hot pot on a quartz or granite countertop momentarily will not normally scorch or make it flake but it is not recommended nor is it covered under warranty if you do.

No quartz is not mostly "epoxy" It is on average 93% aggregate which can be quartz, granite or recycled glass 7% polyester resin, pigments and binders.

Quartz is MUCH Harder than marble or limestone...Though many manufacturer's advertise it as as high as 6-7 in mohs hardness I generally can make it scratch between 5 and 6....marble is @ 3 in hardness..

Granites vary from as vulnerable to low 4 to as high as +6 ..to be clear the mineral in granite that makes it "hard" is quartz.

These are facts annonymous's comments are absolutely not...have no idea where he got his information but mine is from laboratories like SGS and extensive testing of many quartz countertop brands.

Rust stains on HanStone
by: Saltfever

July 16, 2013 I was deliberating on how to clean rust stains off our HanStone Quartz Countertops in our bathroom.

We have an Allen + Roth Brinkley Brushed Nickel Metal Towel Tree that we bought at Lowe's.

Well, it didn't take long for it to rust and of course, it got on our new counter tops. I had tried soap & water, a 50/50 vinegar mix of water and vinegar, and simple green.

I read one of the posts that suggested the Mr. Clean Magic Eraser. Did not work.

My next attempt was with another suggestion, Bar Keeper’s Friend, which I've used for years in my kitchen on almost everything. It worked like a charm.

By the way, we love our HanStone Countertops. We have them in our kitchen and both bathrooms.

Plus, in our kitchen, we had a stationary table made with part of a slab and have bar stools to sit on and I had low boy made and put HanStone on the top.

I think it's easy to clean. Easier than our stainless steel appliances!

Dark Hanstone quartz countertop and I like it
by: Anonymous

We did kitchen/bathroom renovations a few years ago and had Hanstone Quartz counter tops installed.

The pattern (Odessey) has multicolored flecks in it (tan,golden,white)and I don't see any marks or scratches in it despite the fact that I do use it everyday.

I am an avid baker and love to cook. I have never sat a hot pot/pan on it and use a glass board beside the stove.

The countertops are easy to clean with just soap and water. Any water marks around the taps are easily cleaned up with a Scotch Brite never scratch pad.

To keep the countertops looking shiny and new I use a stainless steel cleaner and polish- Weiman brand-that the installers used.

It comes in a spray or wipes. Give it a good buff with a soft cloth and they look perfect.

One thing I was told is to be careful of citrus juices as the acid in them can etch into the quartz countertops if it sits for a long time. We couldn't be happier with them.

Continued rebuttal to "pro experience"
by: Tomco

Continued from above...

Misinformation #3:
"quartz scratches very easily its about the same as marble or limestone nice to look at but dont touch."

Just not factual. Not sure what you are basing your opinion on but perhaps you are speaking of one of the engineered marbles some Breton manufacturers also make. They are made with marble so yes they have the same weakness's as marble.

Both granite and quartz can scratch and chip. Common sense and care is required for either to maintain their beauty.

Just like with a car, a kitchen top getting a lot of use over the years is apt to get a few dings. Accidents happen and you can't guarantee against that.

Quartz Surfacing, just like Granite countertops varies in hardness dependent on the composition. All quality quartz brands have an average of 93% aggregate, 7% resin, pigment and binders. The aggregate varies dependent on the color and effect the manufacturer is going for.

Quartz with recycled glass may test down in the low 5's mohs hardness area..( still MUCH harder than marble or limestone). Some with a higher contents of quartz can test in the high 6's getting close to 7 in Mohs hardness.

FYI Quartz is THE MINERAL in granite that makes granite hard. With out quartz, granite would be very vulnerable to scratching.

OK just wanted to set the record straight.

Rebuttal to comments from "pro experience"
by: Tomco

Sorry but some misinformation posted by "pro experience" that I feel needs to be clarified.

To be clear I have 30+ years in the K&B industry. 20 of that as a contractor doing tile, natural stone and solid surfaces. The last 12 very involved in the Quartz countertop industry.

The thread was started in regards to someone with quartz staining problem and for some reason keeps heading off into a granite vs quartz debate.

They are both great countertop surfaces with their own aesthetic values and detriments.

First misinformation:
"You can burn quartz so taking a hot pan or pot and putting it on top of it will cause it to discolor and blister."

Representing 2 different quartz brands for 10 plus years and handling the warranty claims for both. I never once had a claim in regards to a hot pot being placed on a quartz top and discoloring or blistering it. Not one!

Though definitely not recommended for granite or quartz (USE A TRIVET or Hot Pad), placing a hot pot on a quartz countertop momentarily is very unlikely to do harm..

Left for a longer period of time it can cause enough thermal expansion to cause the top to crack at it's weakest point.

Will a quartz countertop burn and blister?

Yes, if you take a torch to it being as it is 7% resin the resin will burn and blister. Solution...don't take a torch to your quartz or granite top.. ever heard of a "flamed" finish on granite?

Misinformation # 2:
On average it take less then a year of daily sunlight for the quartz countertop to change color but once again the lighter the color the quicker the change.

Some truth here, some misinformation.

Yes because Quartz is made with polyester resin over time exposed to direct sunlight "Darker" (not lighter) colors may have noticeable fading. This is one of the main reasons quartz manufacturers do not warranty quartz for exterior applications.

To be clear quartz has been used in many exterior applications, it's just not warrantied because it is known that in an exterior application where it is exposed to direct sunlight daily it will fade over time.

Obviously some kitchens have more direct sunlight than others but if fading does occur in an interior kitchen, it is subtle.

In over 10 years of handling warranty claims I only had one claim against fading. In that case it had been used in an exterior application.

See next post for further comments....

Hanstone quartz countertops
by: Anonymous

I built a new home and have Hanstone Tiffany Grey countertops. They are awful!!

Salesmen are salesmen and they won't tell you the cons until you call and complain. You have to do that research on your own.

I use the cleaner they gave me or Norwex rags to clean and buff the countertops to get the water drops/rings off. It's back breaking work.

I bought these countertops because they are supposed to be easy to take care of scratch/chip/heat resistant, but if any kind of direct sunlight hits the top you can see every water drop, smudge, fingerprint, and they are dull.

The only time they looked nice was the first week they were installed. Now, I just chipped the countertop with a hard PLASTIC water bottle.

It was full of water, I went to pour water into a glass and just hit the bottom of the plastic bottle against the edge of the counter and it chipped.

Of course, this isn't covered under the pointless warranty and they don't even know if they can fix it because it's one color as opposed to a variety of color like granite.

BUYER BEWARE! DO NOT BUY HANSTONE QUARTZ COUNTERTOPS. I know nothing about granite, but you're better off with laminate or anything else than quartz, particularly Hanstone. Tiffany Grey.

=== Countertop Specialty comment:

Very sorry to hear you've had such a crummy experience with Hanstone quartz countertops.

Quartz countertops certainly have maintenance issues that buyers need to be aware of (but are not often disclosed accurately in marketing), however, in general quartz is an excellent countertop material.

The unfortunate fact is that granite can almost always be repaired, but damage to quartz countertops is almost always permanent.

For your chip you can use Marble & Granite Repair Kit for Chips/Pits. The "gel" is for level surfaces and the "paste" for edges and vertical surfaces.

This thread is about quartz stains not Quartz vs. Granite
by: Tomco

Anonymously spouting off about the truth about quartz but failing to tell the "truth"

Frustrating to see such really bad / false information!

Both Quartz and Granite are great countertop material.

Each year over the last 6 years consumer reports has ran a battery of performance test on a variety of countertop materials and each year has concluded that quartz is #1 & granite is #2 in the best performing countertops category.

IMO they both are equally great "safe" choices. Choose for the look and color you are going for not the marketing hype.

They both have their little plus's and minus's but are hands down the best performing countertop surfaces available today.

A word of caution regarding the pure white quartz countertops. Not to steer you away from them if it's what you want but be aware, they require a lot more effort to keep looking clean and spot free.

==== Countertop Specialty comment:

Agreed.... lots of erroneous information out there regarding both granite and quartz countertops.

But as Tomco stated, you won't go wrong with either.

The testing Consumer Reports does is basically accurate regarding quartz and granite countertops except for the glaring omission of comparable repair options, which is where granite pulls ahead of quartz.

Granite can almost always be repaired, stains removed, surface restored, etc. Whereas damage to quartz usually cannot be repaired or restored and is permanent.

In our opinion that is THE major, relevant difference between granite and quartz countertops.

And the fact that granite has 2000+ color/pattern options and quartz around 100... but most people will be able to find something they like with either so this difference is of minor relevance comparatively speaking.

VIM, who knew
by: Anonymous

Had an oil stain from a cast iron pot left on my white quartz countertop for at least 24 hours (thought it was clean). After reading a few of these posts I decided to use vim and it got rid of every bit of stain.

Quartz Countertops - from pro experience
by: Anonymous

I have been in the granite trade for the last 8 years and all I really have to say about a quartz countertop is that it's a losing battle.

If it does stain VIM will take out most of the stains.

With that said, I'm gonna tell you the truth about quartz countertops and you can decide if you still like quartz.

Quartz countertops can stain. The lighter the color, the easier for staining.

You can burn quartz so taking a hot pan or pot and putting it on top of it will cause it to discolor and blister.

Also, which lots of people don't know, is that quartz is mostly epoxy holding it together and epoxy breaks down in UV light so over time quartz will change color.

On average it take less then a year of daily sunlight for the quartz countertop to change color and once again the lighter the color the quicker the change.

Also, quartz scratches very easily. It's about the same as marble or limestone. Nice to look at but don't touch.

I hope this helps you. And in case you were wondering, granite is way better. Seal it when needed and you wont have to worry about stains or germs.

And if someone feels like posting that granite gives off radiation keep this in mind... one year of exposure to it is equivalent to 2 hours in the sun. Food for thought.

Unexpected Quartz Stain
by: Anonymous

A battery operated intercom we use for our granddaughter when she sleeps over permanently stained our quartz counter.

Had a technician from the company that makes the quartz come to see the stain, and he said they could not fix it or honor the 10 year warranty.

He said the battery in the intercom was corroded and that was not covered under the warranty.

There is nothing on the company's website or their literature that mentions avoiding battery operated devices placed on the quartz.

Plus, there were no visible signs of corrosion on the outside of the device.

The good news is that we took the company to small claims court and won!!!!

White blotches on black quartz
by: Anonymous

I did not find an answer to my problem. I have these white blotches on my black quartz counter top. How can I repair it?

The people that I bought it from can't and won't help me. But they were quick to convince me to buy quartz instead of granite.

=== Countertop Specialty comment:

White blotches on quartz countertops are usually from chemical damage.

Quartz is an excellent surface, but the marketing message tends to gives consumers the idea that quartz cannot be damaged (stained, scratched, burnt).

It can be damaged by many types of fairly common chemicals. It's important to understand that no countertop surface is perfect. All can be damaged. All need particular maintenance.

Usually the damage is permanent. But I'd call the manufacturer of the quartz and see if they can advise.

White rings on quartz countertop

I don't think your white rings are water rings. Apparently, quartz countertops will scorch if high temp pans are placed on them.

I was told that quartz countertops were impervious to heat, but alas it is not.

Hanstone countertop
by: Sorana

It's been 2 years since I have a HanStone kitchen quartz countertop and I haven't noticed yet anything bad to it, as the others mentioned above.

Not a spot. Not even a scratch. Looks like it was installed yesterday.

But, I do not use harsh chemicals or put hot things on top. I only clean it with dish soap.

But I have to mention that mine is reddish-brown in color. I quess it's the right color to conceal any possible spots.

Now I was looking to change the vanity top with a quartz one, but reading your posts here made me think twice.

In the bathroom you have to use chemicals to clean the bowl, sink and the surfaces near to it. If the quartz gets stained or the resins are destroyed, I don't know if it will look good over the years.

Tomco & Don't do Quartz
by: Ryan

Yes, the lighter colored and especially white colors of quartz are the most problematic and I can understand people with these colors thinking quartz is crappy.

However, the vast majority of people who install quartz are very satisfied with it. All in all it is one of the best surfaces you can install in a kitchen.

Tomco states that it is nearly impossible to stain. True, quartz does not stain easy. The problem is that when it does stain, you really can't get it out.

Surface stains can be removed as Tomco suggests, but those aren't really stains, just substances tough to clean.

You don't have to seal quartz, but many granites you don't have to seal either despite what you read that all granite must be sealed.

And as Tomco states:

"The most common household items that stain natural stone e.g. vegetable oil, water, food coloring, balsamic vinegar, red wine will not permanently stain quartz."

Well pure clean water won't stain anything and the others won't permanently stain natural stone either.

But when they do stain natural stone you can remove the stain, which is not possible with most stains in quartz and that is the benefit of granite especially over quartz when there is a maintenance problem.

Otherwise quartz provides an excellent surface on par with granite.

Dont go quartz
by: Anonymous

Quartz stains. With everything. I've hd a quartz countertop for the last year and everything stains it.

A small drop from cups and bangs from pots has left my Quartz countertop with chips everywhere.

If you pay for white be prepared for the, as the manufacturers say, "natural back marks that cant be sanded out"

Biggest and most expensive mistake I've made was installing a quartz countertop. I also used the most expensive and reputable company and am very delicate with things myself.

As for cleaning, be careful.

As you clean even with what the manufactures say you can use the luster of the quartz goes and sometimes stains.

If you need to fix a chip. Don't bother, it'll never look the same.

My advice, purchase Granite. Even if it comes with marks on the stone, or gets stained, chipped and repaired, the surface of the granite, it's look, etc. is at least more forgiving.

As for calling about warranties for quartz countertop. Don't bother.

They just send out contracted losers who do a chop job and make things look worse. Then the guy with his big buddy will stand there telling you how it doesn't look bad at all and bully you into being convinced.

Quartz sucks no matter what company you buy it from.

Quartz and stain resistance
by: Tomco

Quartz countertop surfacing is 99.9% solid and nearly impossible to stain. Residue on the surface appearing as a stains is most often going to be topical.

Topical stains are removed easily with a white 3m scotch brite nonabrasive scrub pad and typical household cleaners like 409 or non abrasive cleansers like Bar Keeper’s Friend soft cream.

We do say "stain-resistant" not stain proof because there are few things (like black magic markers, bleach) that will permanently stain certain lighter quartz colors (pure white being the most vulnerable).

Quartz countertops never need to be sealed. Most granite countertops do.The most common household items that stain natural stone (e.g. vegetable oil, water, food coloring, balsamic vinegar, red wine) will not permanently stain quartz.
