How to Clean and Maintain Natural Stone Countertops

Stone is the centerpiece of a hard-working kitchen, but granite and marble require a delicate touch to maintain their original luster. Unlike synthetic laminates, these natural materials are porous and chemically sensitive; improper cleaning agents like vinegar, lemon, or harsh ammonia-based sprays will dull the polish and cause permanent etching on contact. Mastering the care of your countertops is about creating a routine that avoids corrosive elements while building a protective barrier against everyday spills. When done well, your stone will resist water spots and oil absorption, aging gracefully and deepening in character rather than showing signs of neglect or abrasive scrubbing.

Clear the Countertop First. Remove all small appliances, cutting boards, and decorative items from the countertop. Wipe away loose crumbs and debris with a dry microfiber cloth to prevent scratching during the wet cleaning process.
Spray pH-Neutral Cleaner. Spray a stone-safe, pH-neutral cleaner directly onto the surface. Avoid anything containing citric acid, vinegar, or bleach, which react chemically with the minerals in the stone.
Wipe in Circular Motions. Use a clean, damp microfiber cloth to distribute the cleaner and lift surface grime. Apply light pressure, working in small sections to ensure consistent coverage.
Buff Immediately Dry. Immediately wipe the area with a dry, lint-free cloth to remove all moisture. Allowing stone to air dry often leaves behind mineral streaks or water spots.
Test Sealer Integrity. Place a small amount of water on the countertop and let it sit for 15 minutes. If the water beads up, the sealant is intact; if the stone darkens, the sealant has worn off and needs reapplication.
Reapply Stone Sealer. If the water test showed absorption, apply a stone-specific impregnating sealer following the manufacturer's instructions. Wipe on evenly with a soft cloth, let it sit for the recommended duration, and buff away all excess residue.
