"Our natural granite and stone cleaner can be used daily to brighten and protect countertops, tables, and vanities, leaving behind a streak-free shine - and nothing more. Safe for high-end stone surfaces, including granite, marble, quartz, slate, concrete, travertine, terrazzo, limestone, Silestone, soapstone, and the Rosetta Stone (not recommended). Directions. Spray and wipe with a cloth. Stare at the sparkle a while. No rinsing required."
