How to Clean and Maintain Natural Stone Surfaces

Stone countertops and floors act as the anchor of a home, providing a timeless, durable aesthetic that holds up for decades when treated with respect. Unlike synthetic materials, natural stone is porous; it breathes, absorbs, and reacts to its environment, making the choice of cleaning agents a critical factor in its longevity. Getting it 'done well' means moving away from aggressive chemicals that strip the stone's integrity and toward a routine of gentle, consistent care. This guide focuses on neutralizing the threats to your surface, ensuring that your granite, marble, or slate remains free of etching, staining, and dulling over the years.

Clear Everything First. Remove all appliances, decor, and debris from the stone surface. Use a soft microfiber cloth to wipe away loose dust or crumbs that could scratch the finish during the cleaning process.
Choose pH-Neutral Only. Spray a stone-specific, pH-neutral cleaner across the area or use a mild mixture of warm water and a drop of neutral dish soap. Avoid any products containing vinegar, lemon, or ammonia.
Lift, Don't Push Around. Use a clean, damp microfiber cloth to wipe the solution across the stone in long, overlapping strokes. Allow the cleaner to sit for about a minute if there is light residue, but do not let it dry on the surface.
Buff Dry Immediately. Immediately buff the stone dry with a separate, clean, dry microfiber cloth. Leaving water to air-dry on natural stone can cause mineral deposits or streaks to form.
Run the Water Bead Test. Place a small pool of water on the surface and wait ten minutes. If the water beads up, the sealant is intact; if the water darkens the stone, it has soaked in and the stone requires immediate resealing.
Seal Before It Hazes. If the water test failed, apply a stone-specific penetrating sealer according to the manufacturer's instructions. Wipe it on evenly, let it dwell for the recommended time, and buff away the excess before it hazes.
