Quartz Countertop Stain Removal Tips


Tea stains my quartz countertop.

I thought a quartz countertop stain was impossible since it's non-porous. True?

Should I apply a sealer?

The manufacturer told me to soak the stain with a soap and water solution and then clean it.

Some of the stains are not coming out. I bought quartz to avoid this very problem. What can I do? Joseph, (Dublin, Ireland)


I'll be honest with you... removing a quartz countertop stain can often be difficult. Quartz stains can be permanent in some cases, but I'll give you the best tips.

First, makers of quartz countertops like to tout their product as "non-porous," but they all hedge and claim the surface is stain-resistant and not stain-proof.

Straight from the HanStone website:

HanStone™ is a non-porous material that is highly resistant to stains, scratches and heat. However, it is not stain, scratch, or heat proof.

How Does a Quartz Countertop Stain?

The term "non-porous" would seem to indicate that it cannot be stained. After all, how can quartz be stained if nothing can absorb.... right?

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

In truth, nothing will absorb (or at least extremely difficult), but that doesn't mean that quartz cannot be stained if by "stain" we mean any abnormal or discolored spot.

The end result is basically the same.... a stain, a spot, whatever it looks crummy. It's just the mechanism that is different.

  • A traditional stain occurs when some substance absorbs into a material.

  • Quartz countertop stains usually occur due to chemical reaction with the resin. The chemical, food or drink discolors the resin. Nothing absorbs.

If you are setting tea cup on the countertop and spills are staining or rings are left behind, then the tea is likely affecting the resin used to bind the quartz together.

From the photo, we can see that the ring is tea-colored as well. This is usually what happens when a substance absorbs and stains the old-fashioned way.

So, possibly, it is just the tiniest bit porous or the tea is reacting and binding to the surface in some way that regular cleaning doesn't remove it. Typically, a quartz stain is white or lighter in color due to etching or bleaching of the resin.

Just FYI.... white quartz countertops are the most prone to stains, discolorations, what have you.

HanStone warns not to use any solvent on their quartz countertop. This may damage the resin and color pigments. Solvents are used all the time to clean granite and marble.

Most quartz manufacturers don't warn against all solvents, though. Mainly, just the more potent ones. Acetone is generally okay. But best to test it on a hidden area first.

Cleaning a Quartz Countertop Stain

Here's some good advice on choosing a regular, everyday cleaner for your quartz countertops....

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

Since quartz countertops are 93% quartz (a mineral in granite) it is safest to use products made for cleaning granite and natural stone on your quartz surfaces as well. Learn more about cleaning and polishing quartz countertops.

Now, as for removing a stain....

With a marble or granite stain, I'd suggest using a poultice with hydrogen peroxide or a solvent like acetone. However, this technique hasn't proved very successful for most quartz stains.

A poultice is used to remove stains on a porous surface and it is possible that the acetone could discolor the quartz. Not worth the risk.

Bar Keeper's Friend has proven successful at removing many quartz countertop stains. Use it by scrubbing with a non-abrasive, nylon pad (not the green or red scrubbies).

It doesn't work in every case since sometimes the discoloration is permanent. But, it won't cause any further damage.

Sealing Quartz Countertops

Sealing won't help in this case. Quartz is non-porous or only very slightly so and does not need sealing. A sealer must absorb to work, so it wouldn't have any effect on a quartz countertop and should not be applied.

It may be necessary to remove a sealer from a quartz surface when mistakenly applied.

All considered, quartz is an excellent kitchen countertop material and, in most cases, will stand up to normal use without any issues.

However, no surface is perfect. Every single countertop material available has both pros and cons. All can be damaged or stained in one way or another. It's helpful to recognize this so we are more mindful of how we use and maintain our countertops.

Still, unexpected things can occur. All we can do is learn the limits or weak points as best we can, take precautions, and use suitable cleaning products in order to avoid quartz countertop stains or damage.

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 keepers friend (available at Home Depot).

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.

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.

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.

Bottom line.... Quartz stains
by: Anonymous

It stains. That is the bottom line. I have tried the solutions given here (hydrogen peroxide, etc. they don't work). Get granite.

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.

I had a dark brown quartz countertop installed on my kitchen island that was absolutely beautiful and now after two years it has light-colored water rings clear across it that show really bad.

It looks terrible and I can't figure out how to get them off.

I've tried several stone cleaners. Not sure I would do quartz again!

White rings on quartz countertop
by: Anonymous

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.

I have some faint white rings and two distinct white rings on my dark countertop and have been told it's from scorching.

Dealer is coming to try dying the stains (though it's supposed to be nonporous as well).

I read your comments and tried the Magic Eraser, in 2 seconds, my wine stain was gone. I am relieved!

CAUTION using Magic Eraser. It has been known to dull the surface of quartz countertops. It can work.... glad it did in your case... but a bit of a gamble.

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.

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!!!!

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.

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.

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.

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.

It is recommended NOT to use this product or VIM as over time it WILL dull the surface.

OK once in a while if absolutely need to remove stubborn surface grime.

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....

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.

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.

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!

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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!

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.

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.

Pop Can Rings On Quartz Countertop

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.

Ring Stain From Hot Rubber Bowl
by: Anonymous

Question: I poured boiling water into a bowl with a rubber bottom. Now my quartz has dull rings where the bowl sat. Can I get the shine back?

=== Countertop Specialty comment:

Maybe, maybe not. The resin used to make the quartz countertop may be discolored and often this is permanent damage.

Try scrubbing with Bar Keeper's Friend. This works on some quartz countertop stains and spots, but not always so cross your fingers!

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.

Oil Stain Removal Help!
by: Anonymous

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.

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.

==== Countertop Specialty comment:

Thanks for your contribution Jess! I'd just note to be careful with the Magic Eraser. It can remove some stubborn spots on quartz countertops, but it has been known to cause damage to quartz in some cases as well. Cheers!

Goo Gone for Quartz Stain
by: GSS Khalsa

I have a white quartz counter top that was stained by a wet, red post-it note (go figure).

I tried the Goo Gone suggestion and it worked great with some elbow grease and a well worn, non-scratchy scrub sponge (the type designed for counters and such).

It took about 30 minutes of repeated applications and scrubbing, but it worked beautifully and did not harm the surface.

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!!!!!

Stain on Quartz Countertop from Bottle of Dishwashing Soap

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.

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!

Stainless steel cleaner on quartz countertop... will it stain?
by: Anonymous

A workman used stainless steel cleaner on my new quartz countertop. Is that safe?

Not sure why he did it but he just started wiping it and I was like no, but he had already did it.

Now I am seeing some changes in the color and it's a black countertop. How do I fix this?

==== Countertop Specialty comment:

Can't say for sure if this type of cleaner or the specific brand / product used would cause a problem or not, but various cleaners can discolor quartz countertops. So, it is possible.

Thanks for the solution!

Can't be as bad as Vetrazzo
by: Anonymous

People may be bashing Quartz but that is cause they didn't get recycled glass from Vetrazzo.

The countertop we had was beautiful but if you left anything there by mistake you had a major stain problem.

After we moved we bought Quartz for our new countertop.Most people bashing Quartz don't seem to have much experience with the alternatives which stain far worse.

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?

Works great!!!
by: LEW

409, and the Scotch Brite non-scratch scour pads works perfectly!!!! I let it soak for a couple of seconds, and the stains came right off!!!

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.

Oil stain on Dark Quartz
by: Anonymous

Today we placed a leaking lamp oil bottle on the counter not thinking oil would hurt the stone. When we picked up the bottle the dark quartz had an even darker ring on it. Is there any way to salvage the quartz?

=== Countertop Specialty comment:

Try Bar Keeper's Friend. The stain should be on the surface and can likely scrub away.

Baking soda
by: Anonymous

I have white quartz in my kitchen and I got about 3 rings from the tea pot. I read all the advices here but I decided to use baking soda.

Rings came off right away.

I sprinkled some water and then baking soda on those rings and then I used some paper towel and I gently scrubbed and the rings just disappeared. No scratches whatsoever.

Do the scrubbing in circular moves.

Bar Keepers Friend++
by: Anonymous

The maid/cleaners set a dripping can of something (cleaner?) on the quartz island top and left a real nice, round stain/etch mark!

Gentle action with a warm wet sponge and appears to have worked.

Quartz countertops...are quite nice. I suggest all the negatives written either wipe up your messes right away or just stop spilling. I'm just sayin'.

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.

Overpride oven cleaner stain
by: Anonymous

I was cleaning my oven with overpride and put the heavy duty plastic bag with the racks in my grey quartz worktop, thinking the bag was sealed and hard wearing, however the solution leaked and has stained my worktop.

Is there anything I can do to get rid of the stain?

Many thanks, Suzi

==== Countertop Specialty comment:

Over cleaner is typically a very harsh chemical and will damage many types of surfaces. Sorry to say that the stain or discoloration caused on your quartz countertops may be permanent.

But try cleaning with Bar Keeper's Friend.
