Are you sure those are scratches and not surface scuff marks from pots?

I am not sure. I tried to use the cleaner to scrub but they did not go away. They may be marks left by appliances but I don't know how to remove them!

Can you feel the scratches?

No I cannot feel them. They don't seem very deep.

No, don't use Barkeeper's Friend! The fabricator ruined my Caesarstone with it. I tried light pressure with Bon Ami on my seam and I can see dullness when the light hits that area. If there's no backlighting from a window or light fixture where the scratches are, you might be okay with either of those products, but I would only use them as a last resort.

I have taken off metal marks on the edge of my quartz with a tiny bit of CremaBryte glass cooktop cleaner on my fingertip.

I second mayflowers's recommendation. Use it sparingly and rub lightly.

I agree no to arkeeper's Friend and it has been my friend for many years when I did not have quartz countertops. Use Soft Scrub Liquid Gel with Bleach.

To echo others - that does look like scuff marks from pots. I get the same marks around my sink from scrubbing pots. Cerama Bryte and some elbow grease will get them out.

If you try the CeramaBryte, go easy. I discovered it on my own, thinking it polishes my glass cooktop without scratching it, so let's give it a try. It's not an approved cleanser so you might test it on the smallest mark first. If it doesn't come right out, don't scrub it because that could scratch it if there's any abrasive in CeramaBryte.

I have new LG Viatera quartz. I've found that Greased Lightning cleaner (an approved product for my brand) takes marks like yours up with no scrubbing effort.

I have found I don't care for CeramaBryte to clean the cooktop. Seems to leave greasy looking streaks on the cooktop.

Thanks for all your suggestions. I think I am also leaning to towards the theory that they are scruff marks from pots or an appliance (the Vitamix was stored in that area briefly).

I love bar keepers friend. However, since the countertop is so new and shiny I don't want to experiment with it too much and risk dulling it or damaging it in any way.

I already tried Soft Scrub Liquid Gel with Bleach + elbow grease which is the manufacturer recommendation, and it did not help. Granted I did not let the cleaner soak for over 2 minutes.

I contacted the fabricator and am waiting to hear back from them. Let me check with them about CeramaBryte and Greased Lightning cleaner.

You have to buff it well with clean paper towels. It's a pain.

Well, I don't like that idea, Mayflowers. I am too old to have uneeded pain and aggravation. Will have to see what else I can find.

All the creams are the same. I saw a spray at Home Depot that might be different. I can't remember the name but it might have been Range Meister cleaner that I saw on their website.

If those marks weren't there at installation and I were the warranty agent for Caesarstone, I'd rule them customer abuse. Black with contamination means they're fairly deep. I'd charge a lot to remove those and I'd only try after the customer agreed in writing that the tops were ruined.

@Joseph: They are not deep (I can barely feel them). The counters are just a few weeks old and were kept covered by rosin paper. We started using them mildly barely a week ago. Our kitchen is not even fully functional yet. I don't know what kind of abuse this constitutes. I was led to believe that Quartz can stand up to rigors of a functioning kitchen ....

Thanks, mayflowers. I will look into the Range Meister.

vishketan:

When you're a warranty agent, you have three choices. 1. Fabricator/Installer error, 2. Manufacturer defect, 3. Customer abuse. These lines can blur. An electrician can make these marks and it would probably fall under "Customer abuse". I don't mean that you specifically abused the tops.

@Joseph: Thanks for the clarification. Anyway I am waiting for my installer to come out and have a look.
