Granite itself is approximately 95% stain resistant but, we recommend using a food grade, silicone impregnator on all natural stone products. Some stones require multiple coats. This will insure lasting life and beauty. We also offer a polish that contains sealer for a long-lasting seal and shine. Unsealed, granite can absorb stains such as oil, which can ultimately cause dark spots or discoloration. Oil Stain remover can be used to get stains out of natural stone.
Aluminum and some black rubber appliance feet can leave a mark on stark white quartz. They will clean off with the proper products. Quartz does not require any maintenance as it is 99.9% non-porous.
