How to Clean and Protect Granite Countertops

Granite is a workhorse of the modern kitchen, prized for its durability and unique mineral patterns. Because it is a natural porous stone, it behaves differently than man-made surfaces like laminate or quartz. If you treat it like a cheap countertop, using harsh acidic cleaners or leaving spills to soak, you will eventually dull the finish and invite permanent stains into the rock itself. Done well, maintaining granite is a ritual of gentle care rather than aggressive scrubbing. When you seal it properly and keep the surface clear of acidic residues, the stone retains its deep, polished luster for decades. This process isn't about deep cleaning—it's about preserving the integrity of the stone's protective barrier so it stays food-safe and beautiful for the long haul.

  1. Clear the deck completely. Remove all items from the countertop surface to ensure you can reach every square inch. Use a dry microfiber cloth to wipe away loose dust or crumbs that could scratch the finish during the wet-cleaning phase.
  2. Gentle wash protects the seal. Mix warm water with a few drops of pH-neutral dish soap or a dedicated stone cleaner. Dip a soft microfiber cloth into the solution, wring it out until damp, and wipe the entire surface in overlapping circular motions.
  3. Dry immediately to prevent streaks. Immediately follow the wash with a clean, dry microfiber cloth. Buff the surface until all moisture is gone and the stone reflects light evenly.
  4. Test the water bead. Pour a tablespoon of water onto a high-traffic area of the counter and let it sit for 15 minutes. If the water beads up, the seal is intact; if it darkens the stone or disappears, it is time to re-seal.
  5. Reapply protection where needed. If the water test showed absorption, spray a granite-specific penetrating sealer onto the surface. Use a soft cloth to work the product into the stone, following the manufacturer's specific dwell-time instructions.
  6. Buff away excess sealer. After the recommended dwell time, use a clean, dry microfiber towel to buff away the excess sealer residue until the surface is clear. Allow the stone to cure for at least 24 hours before heavy use.
