Clean stone surfaces with a neutral cleaner, stone soap, or a mild liquid dishwashing detergent and warm water. Similar to any item cleaned in your home, an excessive concentration of cleaner or soap may leave a film and cause streaks. Do thoroughly rinse and dry the surface with clean, clear water after washing. Do blot up spills immediately. Do protect floor surfaces with non-slip mats or area rugs and countertop surfaces with coasters, trivets, or placemats.
