Granite Gold was created by stone care experts with more than 40 years of experience in the stone industry. Granite Gold products were developed to care for and protect any natural stone surface, including granite, marble, limestone, travertine, onyx and slate. Granite Gold can be used on any finish, including polish, honed, sandblasted, etc. Granite Gold is also safe for use on manufactured stone surfaces such as ceramic tile, porcelain tile, concrete, Corian, Silestone, Terrazzo and Formica. Granite Gold products will not damage polished nickel and/or chrome hardware and faucets.
