I had a feeling it was Chinese. The Chinese use a different manufacturing method than the Breton Technology used by Cambria, Caesarstone, Silestone, and the other big manufacturers. When I bought my Pentalquartz, which is Breton-made in Vietnam, the warehouse manager told me that the owner of Pental, which is a big west coast granite company, went to China to see their manufacturing facility, and he wouldn't buy it. He said the resins are cured at lower temperatures for shorter time periods. So there's the cost-savings, but it's not as durable. I've read here of surface pitting with Chinese quartz. That's unheard of with Breton quartz. So now we see your water marks, which is ridiculous. I would have them take that junk out and buy a reliable brand of quartz myself. I'm saving your photo to show others what can happen when they buy Chinese. They never believe me that Chinese quartz can have problems. They just look at how pretty it is and how much money they save.

I have a kitchen table from Room & Board that has a white quartz top. It does occasionally stain with ink, pencil, colored pencil, etc. Normally I use a homemade cleaner with water, alcohol and blue dawn. It gets everything out for me. I did have one stain from the magnet on the back of my phone case which came in contact with water. I used bar keepers friend and it came right off. I am only left with a small mark that was on the table when it was delivered (we were out of the country and someone else received the table and didn’t say anything to the delivery men). It appears to be a small ink mark. We have been able to dull it slightly, but haven’t been successful at removing it. I will try the greased lightning suggested above, and maybe diluted bleach as a last resort.

April_Espinoza I had a sales tech come to my house last month. He had no answer for the countertop being how it is. I am getting a new one fabricated and installed on MSI expense, but I do have to repay a plumber for my sink/dishwasher hookup. You are correct, as time has gone on, the top is getting worse. You can see ring spots of every glass put on it, dull spots/smudges...I have no idea why it is like this. I'm leary on getting the new from them because I am wondering if thats just their product. I have never used a harsh cleaner or sponge. It will get worse as time goes on...im glad I contacted MSI bc they are backing the product

I have had Caesarstone for a couple of years now and I'll share some of the tips I learned from them and I've gotten over the years. -As much as you can, wipe up the spills. If you let it sit, you can soak it with warm water and dishwashing liquid. -Don't scrape hardened spills with razors or knives. Scrape them with a plastic ice pick. -Don't use abrasive liquids or solutions during cleaning. -Always use cutting boards and trivets whenever you're cutting vegetables or meat and when you need to remove a hot pot or hot pan. -Lastly, after cleaning the countertop, wipe down everything with a paper towel to prevent having watermarks. I hope these help!
