Daily cleaning should consist of a soft white cloth and a neutral non abrasive cleaner. Buffing may be required periodically to clean any streaks. Once a week a good quality stone revitalizer should be applied to the surface to help avoid any staining. All GCA granite countertops come from the factory with a sealant applied to prevent wear. It is recommended that a stone impregnator sealant be applied to the surface every three years.
