Quartz Countertop Stain

QUESTION:

I have a HanStone quartz counter top. Tea stains it. The manufacturer has told me to leave a soap/water solution to seep in and then clean it.

But I thought quartz is non porous and should not stain. Is there a sealer I should use for quartz? Some of the stains are not coming out. I bought quartz to avoid this very problem. Please advise?

ANSWER:

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

Straight from HanStone website:

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

How they can legally get away with these contradictory statements is beyond me. It's unfortunate that they feel the need to be misleading, but they have to try to gain an edge somehow since granite has a long-established and better reputation.

You probably wish you knew this sooner, but there are some varieties of granite that are truly stain-proof. They are so dense that nothing gets absorbed, unless maybe a liquid was able to sit a few days without evaporating, which of course is near impossible.

If you are setting tea cup on the countertop and spills are staining, then the surface is obviously porous.

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.

Because of this, I'm a bit hesitant on making a recommendation about what you should do to clean it.

Cleaning The Stain

Typically in this situation with marble or granite I'd suggest using a poultice.

In your case, I don't have too much confidence that it would have any effect.

Sealing

I would call HanStone and ask them if a sealer will damage the surface. I doubt it will, but I'm not certain.

If not, then yes I'd apply one of these recommended marble & granite sealers. Follow the directions carefully and wipe the excess sealer off the surface before it dries.

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 get 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.

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 scrach... looks like it was installed yesterday, but I do not use harshy chemicals, not even put hot things on top, and I only clean it with dish soap, but I have to mention that mine is redish-brown in colour, I quess the right colour 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 before, in bathroom you have to use chemicals to clean the bowl, sink and the surfaces near to it, if the quartz gets stained or the resines are destroyed don't know if will look 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
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).

white bloches on black quartz
by: Anonymous

i did not find an answer to my problem. i have these white bloches 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 convience me to buy quartz instead of granite.

====ANSWER: White blotches on quartz countertops are usually from chemical damage. Quartz is an excellent surface, but unfortunately the marketing message gives consumers the impression that quartz cannot be damaged (stained, scratched, burnt) etc..... but it can be damaged by many types of fairly common chemicals.

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

Unexpected 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

Hello
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 its a losing battle. If it does stain vim will take out most of the stains.

With that said im gonna tell you the truth about quartz countertops and you can decide if you still like quartz.

Quartz countertops can stain the lighter the colour 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 discolour and blister.

Also which lots of people dont know is that quartz is mostly epoxy holding it together and epoxy breaks down in UV light so over time quartz will change colour. On average it take less then a year of daily sunlight for the quartz countertop to change colour but once again the lighter the colour the quicker the change.

Also quartz scratches very easily its about the same as marble or limestone nice to look at but dont 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

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.

==== ADMIN COMMENT: Agreed.... lots of erroneous information out there regarding both granite and quartz countertops. Mainly it comes from the quartz countertop manufacturers and then gets passed around.

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!!

Salesman are salesman 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.

====Admin 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 countertops are excellent countertop materials.

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.

Good Luck!

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 stuborn surface grim.

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 discolour 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?

Misinformatin # 2:
On average it take less then a year of daily sunlight for the quartz countertop to change colour but once again the lighter the colour 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 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 Counter tops. 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
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.
