Are very picky what they like to be cleaned with. Don’t use CLR kitchen and bathroom cleaner on this type of countertop it will stain. Instead just use your Norwex cloth and then shine with the shining cloth. It sparkles. Or if you don’t have Norwex then use a foaming glass cleaner such as CRL “Sprayaway” glass cleaner. This product puts on a nice shine and smells nice too. We sell it so you can get it from us.
