Stone Enhancers To maintain the beauty of your stone products, follow the guidelines below: Protect surfaces from scratching, staining and etching by keeping them free of debris or sharp objects. Wipe up spills immediately Avoid contact with chemicals, particularly acid-based materials Clean with pH neutral products or those especially formulated for use on stone, like the Foam Stone Polish we offer. It is not recommended that you use water-based solvent for dark granite because it will remove the polish from the surface. Remove stains with special absorbent poultices formulated for use on stone. After a period of use, apply a penetrating sealer to prevent contaminants from being absorbed into the stone. Renew the surface on polished granite (granite with a high gloss surface) by buffing with special stone polish powders or creams. Do not use granite polish on granite with a matte finish, which has been honed rather than polished. (Penetrating sealer may be used on both polished and honed granite.)
