All I've ever heard is bleach. I believe it works.

My quartz said not to use bleach on it. I would start with a non-abrasive cleaner like soft scrub. What have you tried? I have had my quartz almost a year and no stains. Have you tried soap and water with a lot of force?

agree with jhmarie - soap and water and what they used to call "elbow grease"

lol eageree - I had typed "elbow grease" and changed it because I didn't know if the younger generation would know what I meant:)

Are we telling our age?

Call the manufacturer and ask them what you should use as you don't want to use something that will make it worse or void the warranty. I would also ask them why the quartz took this color on.

Thanks for everyone's advice.

I used nnigrt's method, they came right off. Thank you, nnigrt! You saved my day!

i'm so glad! it took me 6 months of trying everything before i thought to try barkeepers friend and the marks on my floor budged!

I just got my brand new quartz countertops and they are gorgeous. Today I was cutting some flowers for a vase and the yellow one stained my counter top. I had laid out towel for easy clean up but afew yellow ones got on my counter top. I read how to remove stains from quartz and I took jhmarie's advise. I put a little dish soap (Dawn) and it came right off. I was so happy. Thank you jhmarie's.

I used “Magic Eraser” pad and dish soap. Worked really well, no hard scrubbing needed.

I'm putting quartz in my laundry room.
I always thought that it was stain proof. That's my reason for choosing quartz over granite.. plus I didn't want to have to be re-sealing the granite every few years. I thought it was in destructible. best material for counter tops???? Better than granite.. I think the soap stone is the best but super expensive. So I picked quartz, I'm not quite sure now.

Chacha53- Best material for countertops is Corian. After 18 yrs my white Corian in my Master bath still looks brand new. Have yet to read one complaint against Corian on houzz. Unfortunately, the marketing guru's have convinced the public that quartz is the "IT" product to have so Corian isn't as favorable.

We had corian for more than 20 years in our kitchen, and nothing is stain proof. We looked at the new patterns for corian and quartz, as picked the latter. You will have no regrets with either.

Oh, I always thought Corian was a brand name of quartz?

lanoway-Corian is a brand of solid surface material created by DuPont. Its primary use is as a countertop/benchtop surface, though it has many other applications. It is composed of acrylic polymer and alumina trihydrate (ATH), a material derived from bauxite ore. Corian is the original material of this type, created by DuPont scientists in 1967.[1] A number of direct solid surface competitors to Corian have emerged since the expiration of DuPont’s patent on solid surfaces.

Quartz is crushed quartz with a resin binder hence the name "quartz."

ChaCha, Quartz is fantastic and much better than the granite and easy to clean. BTW, the person posting the Bar Keepers Friend, my installer and the company said: no to that. Baking soda paste and a cloth should remove most anything.

As to Corian, oh wow, I've seen some real issues with it over time. If you travel you will see damaged sinks, counters etc. At least, that has been my experience.

Sandi- "Quartz is fantastic and much better than the granite." Just wondering what your experience has been with granite that makes it so much better than granite?

And as far as traveling, are you sure your experience hasn't been with a different material -perhaps a fiberglass material that could be confused for Corian?

Granite has to be "resealed?" every year or so vs no further effort on the quartz. I had not known before looking at solid surface countertops about the extra care granite requires and after comparing the two surfaces the quartz was the choice for me. As to the Corian, you may be right. But, I have seen some really bad Corian. It does scratch, stain and need marks buffed out. I do not like it nor would it be on my list to use. JMO. Thanks.

Yes, granite has to be resealed but it is an easy DIY and I haven't found it needed any extra care. I've owned 5 homes with granite and my current homes granite is 18 yrs old and hasn't needed to be resealed yet. My last house I didn't need to seal until the 15th yr. And I cook and bake a lot. I've had quartz in a guest bathroom that didn't get much use. I had issues with watermarks on that surface and it was a polished surface. I've also experienced Corian in 2 kitchens and 6 bathrooms including a shower. My 18 yr old bathrooms and shower Corian look like the day they were installed. My sister left dark hair dye on my white Corian and I didn't discover it for over an hour and it wiped (not scrubbed) right up with no staining. And if I do have scratches that I want out a buff will do that. Whereas Quartz is highly scratch resistant but still can get scratches and from my understanding can be quite difficult to remove. Though I do not have any experience with that so I don't know the level of "difficulty." Based on threads I've read on houzz, others are saying that they have experienced staining and chipping on their Quartz.

No surface is going to be perfect and your own experience is going to tell you whether you use a certain surface again. Like everything, even if you do a lot of research you just hope that it will perform like you believe it will.

Sandi- Enjoy your Quartz and I hope it meets your expectations to be maintenance free :)

Sandi:

Solid surface (Corian) does not practically stain. It scratches more easily than other surfaces, but, like stainless steel, it's easily and economically refinished.

Quartz has about the same heat resistance as solid surface, but while heat damaged solid surface is inconspicuously repaired, heat damaged quartz is replaced. Granite has more heat resistance than either, but a trivet should be used on all of them, making them essentially equal.

I've repaired countertops twenty years or so, so I kinda know what I'm talkin' about.

I moved into a new apartment with white quartz counters less than two weeks ago and so far anything that comes near them stains them, even when immediately wiped up. Makeup is the worst and the only thing I haven't been able to get out (why would you put counters in the bathroom if makeup can't touch them???) My lip gloss had a tiny bit coming up from under the cap. It rolled across the counter and left a huge pink dashed line across the entire thing. I've tried soap and warm water, peroxide, lemon juice, non-acetone nail polish remover, a baking soda and peroxide paste covered by plastic wrap, elbow grease, and so far nothing even fades the stain. I was also advised not to use bleach, but at this point, I don't want grey, shadowy stains from my eyeliner barely touching the counter and pink stains all over from my lip gloss barely touching it. Any other suggestions?

Brooke- Sorry to hear that you are also experiencing that Quartz isn't the stain free surface that the manufacturers are promoting. I don't know if you have seen this thread but if you haven't, you might glean some info from it that might be helpful.

"Any other suggestions?"

Yeah. It's called "Corian" and doesn't stain or etch.

Update: I used Bar Keeper’s Friend aka Savior in a Bottle, but the liquid one. It took a little elbow grease, but everything came out. Even the stains from moving in (my husband set EVERYTHING on the counter and assembled some small furniture without covering it, put the trash can on top of it, etc.). Surprisingly though, the makeup was the hardest to get out, and it only just barely touched the counter for a second.

Brooke Nelson:

Please look at the areas you've cleaned under low level light. With the lights on, get down to nearly countertop height and with your eyes, run the reflection(s) over the cleaned and uncleaned area and see if there is any change.

That’s why I was worried about using something like Barkeeper’s Friend or Ajax. I’ll have to check it like you said.

Brooke, how did the counter top fair using Bar Keepers Friend?

Peroxide (10%) from CVS/Walgreens. I also added a NatureMade Prenatal vitamin with DHA and iron (as a catalyst) and worked it in with a Mr. Clean Magic Eraser. Wiped that off. Poured more peroxide on it and left it for 5 min. Wiped that off. Repeated 3x. Looks pretty good. Oxyclean SoftScrub Gel also worked well (not as potent as the peroxide). I have White Quartz and I stained it with burnt Trader Joe's Orange Chicken. Someone recommended toothpaste, but I didn't try it. You really need a good oxidizing agent. Iron (Fe) will increase the bubbling and hasten the reaction. A tooth whitening strip from Crest might work or a whitening toothpaste (those have peroxide in them as well) for a spot clean.

Like the photos show, I too got charcoal grout on my new white quartz counter. I tried the Barkeepers Friend with some elbow grease and it worked perfectly! Thank you so much, ninigret.

Do NOT use Barkeepers Friend. It is acidic. I used it to take out a stain on my quartz countertop with just a rag, and it damaged the resin so now my black quartz has a lighter/cloudy area. I subsequently looked it up and saw that this is a known problem. There is no way to fix it, except PERHAPS professionally.

"There is no way to fix it, except PERHAPS professionally."

Yes, your pro should use the Quartz Renew kit from Gran Quartz.

my brand new white quartz counter also has black color stain from the backsplash tile grout. what product can I use?

Quartz Countertop Care by Keystone Granite, Inc (Oregon)

Caring for Your Quartz Countertops

Cleaning
1. Regular cleaning should be done with a mild soap or detergent and a soft cloth. Make sure the soap is non-bleach and non-abrasive.
2. Although stain resistant, Quartz countertops are not stain proof. Wipe up liquids as soon as possible. Quartz will resist stains for a short period of time, but all colored liquids should be cleaned up promptly.
3. A glass or surface cleaner, such as Windex, can be used for heavy or dried on stains. Use a non-abrasive sponge. For deep cleaning, spray a generous amount; leave on for ten minutes, then wipe away.
4. Scrape away grease, gum, and paint with a plastic putty knife or razor blade. Use a degreasing cleanser, formulated for Quartz countertops, to clean off grease. Rinse away immediately.
5. Remove ink or permanent markers carefully with an oil-based cleaner, like Goo Gone. Rinse with warm water immediately after the stain is removed.
6. Heavy, stuck on, hard to remove stains such as nail polish can be removed with a mixture of acetone, Ajax, and water. Dilute the Ajax to the point of minimal abrasiveness. Wipe away immediately.

Preventing Countertop Damage
1. Use hot pads or trivets for pans, crockpots, and electric skillets. Quartz can resist temperatures up to 300 degrees Fahrenheit, but it can be damaged by quick changes in temperature. Also known as “thermal shock.”
2. Avoid using knives directly on Quartz countertops. Quartz is very scratch resistant, but they can be damaged when forcefully hit with sharp objects. A cutting board is recommended.
3. Avoid cleaning with highly acidic or alkaline cleaners, such as nail polish remover, turpentine, oven cleaner, bleach, drain cleaners, dishwasher rinsing agents, etc. Clean immediately with a mild detergent and rinse, if they are spilled.
4. Avoid pressure or force on your countertops, such as dropping a heavy pot, as it can chip or crack the stone.

Acetone (nail polish remover) is an excellent engineered stone cleaner, just don't let it pool or trap it under the can. Wiped on and off immediately, it will do no harm. It hasn't in 25 years anyway.

I had granite countertops in our kitchen for 20 years (we moved then) and they did not have to be re-sealed ever. i asked the granite company because i heard that granite chipped and also had to be re-sealed but they said it depended on the quality of the granite. a good quality granite does not have to have any work done to it. They were right.
