With proper care any natural stone will hold its beauty for a lifetime. We recommend sealing all natural stone products before & after grouting, and at least 2-3 times a year depending on application. Always test sealers in a small area or spare piece of tile before applying to whole area. Chemically sensitive mild PH cleaners should be used when cleaning natural stone. Always avoid using harsh chemicals and acidic cleaners. Never use bleach or vinegar on natural stone products. Warm water and microfiber cloths are ideal when cleaning the surface. Do not use scrubbing pads as this may scratch the surface. Keeping the surface clean regularly will help prevent scratching from everyday grime.
