If it was like that on install I'd be asking for a replacement. But first, you can try cleaning it.

We have dark gray quartz now and it's impossible to clean. Everything shows, and everything marks it. Rings everywhere. Water doesn't clean it AT ALL. Soap and water is ok but not great, and requires paper towel dry otherwise the water marks show. The best is to use a product. I haven't bothered with anything other than method cleaning products as of yet because this is a rental, but in your case I would try getting some quartz cleaner first and see if that can help. Don't use baking soda/vinegar or barkeepers friend because then it will etch. It may be etched now, but you'll need something better than water to clean it anyway.

Thank you! I was told to keep cleaning it and it "should" get better, or I might have to go buy a product from Home Depot and try fixing it that way. I insisted they come out and properly complete what they started so they are now coming out. I am concerned that this indeed is not fixable and unsure why it even left the warehouse!

I am wondering if there is a way to seal this so that the problems you are incurring will not happen.......

Try some acetone on a paper towel please. Maybe some Tenaz Quartz Toner.

Problem with quartz is that industry is not telling the truth. Quartz is hardest material, harder than granite but the so called quartz slabs are not pure quartz, most of the quartz slabs has less than 60% quartz rest is all sort of industrial waste like granite/marble powder from quarry, glass and concrete and biggest culprit is the resin. Most manufacture states percentage of quartz vs resin by weight, this is just the marketing tactics, stone is heavier than plastic resin, if you look at volume most slab has 15-30% resin. Resin is biggest culprit when it comes to quartz staining and dull marks, resin is very soft material and it reacts with any household product like lemon juice, vinegar, wine, soap, tomato juice etc. and when you spill nay kind of acidic/alkaline on quartz it creates etch mark, which looks like stain but it is a chemical reaction with resin, which you cannot get out unless you re-polish surface by professional guy. Even regular use abrasive object like magic eraser, or scotchbrite will create a dull mark when you rub quartz countertop with it for cleaning, it is cutting though soft resin and destroying fine finish. Quartz need to be treated like a baby, it is good for display in galley but not for daily use in kitchen. Egypt pyramid has granite which has withstand 3000-4000 year of abuse but todays quartz cannot withstand normal use and tear of daily kitchen activity. I made mistake of installing quartz, but I will never go back to quartz natural stone/granite is best option for me.

What brand countertop do you have? I have Silestone, color charcoal soapstone, no issues from the day of installation to now (several years later). It cleans up great with dishsoap and water. I think you need to contact your installer again. Did you “sign off” on the paperwork with your countertop installer after installation?

That is the fabricators problem to fix. Hopefully you didn't pay yet so you have some leverage.

We have pental quartz and nothing we've put on it has stained it in the 4-5 years its been in our kitchen. I do think the name choice is unfortunate but it sure has been easy to live with.

What was the end result? Did you find out what caused it? And how did they fix it?

The company came back out and used a special cleaner and fixed the cloudiness problem. Although I must say that black countertops show every single water mark regardless. Not sure I would choose black again.

The company came back out and used a special cleaner on it. The film was from the fabrication. Although the black counter tops shows every single water mark. Not sure I would ever go with black again.....

Thanks so much for the reply! We may be dealing with something similar. We're waiting for them to come back out to take a look at it.

Do you know what is the cleaner they used? I am experienced the same.

We are experiencing the same problem! please share the product name.

The only solution to remove dull marks is to repolish the entire countertop using professionals who use a diamond grinder. Next time, avoid installing quartz. Regardless of the manufacturer, opt for natural stone like granite or quartzite instead.

HU:

That is not the only solution. Engineered stone is here to stay, no matter how much you and Patricia hate it. Check out some of the quartzite horror theads here, there are more than four, and get back to us please.

Hello, the fabricator never mentioned what they use and its been awhile. sorry I can't help. Try calling your fabricator since it was a film from their fabrication
