Our counter top is Silestone quartz. I use any brand of all purpose cleaner, like Clorox GreenWorks, Method, Mrs. Meyers.

I too have Silestone and use Clorox wipes to clean my counter tops.

Try a microfiber cloth just slightly damp with water to remove the cloudiness.

I have Cambria quartz, typically use Method or just a little Dawn to do the daily cleaning but when I want them to really shine I use a little windex (vinegar based) with a microfiber cloth. Works beautifully.

I would recommend you contact the company who sold this to you as they will know what you should do. Unfortunately, you cannot use everything on quartz. Dish detergent like Dawn is something you could try.

Thank you for the suggestions. I did do soap and dawn with a sponge and didn’t seem to help. I do not have the contact for the company as I purchased this home and was not a renovation.

Can you contact a company such as Cambria and ask for some advice?

Try acetone on a paper towel please.
