@k_giannone- Ok, so I didn't wipe the counters off for a few days ( because I wasn't home) .....My older kids ate some chinese food and did a terrible job of cleaning up and I noticed a more prominent "greasy" coating on the counter in the area where they attempted to wipe it up. It was much more "spotty" than usual. I tried dawn dish liquid with a paper towel and noticed it looked streaked and spotty and terrible:( Then I tried the pledge I raved about. No luck. I began to panic, I tried windex with a paper towel and it still looked weird. Then I remembered I had used a microfiber cloth before. That did the trick! I had to "buff" out those areas to make them less spotty and less streaked. It took way more time than I would like......but it looks as good as knew now:) Try and buff yours out with a dry microfiber cloth.

Any marks on my quartz counter that have terrified me have come out with a light application of Barkeeper's Friend Soft Cleanser for Porcelain. Wet a cloth, put a little of the stuff on it, rub very lightly in circles on the mark (red wine, weird circular differences in reflectivity etc), then rinse with a lot of water, and it's perfect! We have had our quartz since 2017 and with this trick it is still completely like new. Note that we do not set the Barkeeper's Friend bottle on the counter, and the cloth we use for Barkeeper's Friend is different from any other cloth in the kitchen, because prolonged undiluted contact with the stuff could damage your counter, so be careful, apply judiciously and hopefully you'll have the same success we've had.

Well, I decided to just suck it up and live with what I have and try to be as careful as possible. My entire project dragged on for soooo long and I had multiple issues with my GC so I just wanted the entire thing to be over and done with! Fortunately, I have not had any additional chipping, but I'm sure at some point I will. My biggest complaint other than chipping is that I've discovered that my light colored quartz is easily scuffed/scratched if I rub against the face of the countertops with a belt buckle or zipper. The scratches are easily removed, but it is annoying. I don't think I would do quartz if I had to do over again. I am so sorry for your experience. Your situation sounds awful! Good luck!

there are a zillion versions of each approach available in the Photos section of this site -- just search for "quartz counter and quartz backsplash" or "quartz counter and tile backsplash" and start bookmarking the ones you like. eventually you'll get a sense of what fits your taste.
