How to Clean Granite Countertops Safely (Daily and Deep Clean)

Granite is durable, but it's a natural stone with tiny pores. The wrong cleaner can dull the surface or break down its sealer over time. The good news: caring for granite is simple when you use gentle products.

Daily Cleaning

• Mix a few drops of mild dish soap into a spray bottle of warm water.
• Spray the counter, wipe with a microfiber cloth, then dry with a second cloth.

Drying prevents water spots and keeps the surface shiny.

Disinfecting Granite

Use a disinfectant labeled safe for natural stone, or isopropyl alcohol diluted with water (about 1 part alcohol to 2 parts water). Spray, let it sit briefly, wipe and dry.

Removing Stains

• Oil-based stains (cooking oil, grease): Make a paste of baking soda and water, cover with plastic wrap, and leave overnight. Wipe off and rinse.
• Water-based stains (coffee, wine): Make a paste of baking soda and a little 3% hydrogen peroxide, apply the same way, and test first on a hidden area, as peroxide can lighten dark granite.

Test Your Sealer

Drop a little water on the counter. If it beads up, your sealer is working. If it soaks in and darkens the stone within a few minutes, it's time to reseal. Most granite needs resealing every 1–3 years.

What Never to Use on Granite

• Vinegar, lemon or other acids
• Bleach or ammonia
• Abrasive scrubbers or powders
• Many all-purpose cleaners not labeled stone-safe
