How to Clean a Granite Countertop: Step1

Blot up spills immediately, before they penetrate the surface.

Clean stone surfaces with a few drops of neutral cleaner, stone soap (available in hardware stores or from a stone dealer), or mild dishwashing liquid and warm water.

Use a soft, clean cloth to clean the granite. Rinse after washing with the soap solution and dry with a soft, clean cloth.

Remove a stain on granite, basing the method on the type of stain. Mix a cup of flour, 1-2 tablespoons of dishwashing liquid with water to make a thick paste. Put it on the stain, cover with plastic wrap, and let it sit overnight.

Scrape away the mixture with a wooden utensil and rinse. If the stain is oil-based (e.g. grease, oil, milk), use hydrogen peroxide in the paste instead of dishwashing liquid – or try ammonia on it.

Try a mixture of 12 percent hydrogen peroxide mixed with a couple drops

Use a lacquer thinner or acetone to remove ink or marker stains from darker stone. On light-colored granite, use hydrogen peroxide to these stains. This also works for wine stains

Mix molding plaster and pure bleach into a paste and spread over a wine, ink or other non-oil stain. Leave on for 30 minutes, then remove and rinse.

Paste a mix of molding plaster and water over an oil-based or fat-based stain. Mold it into a bird’s-nest shape and allow to stand for 3 hours. Remove and rinse.

Reseal the countertop every year or two years. Check with the installer for recommendations. Use a non-toxic sealer on food preparation areas.

Natural Stone Care Facts:

Stone is a material that is made of natural minerals that may react to chemicals that are not intended for stone care use. Stone is a common term that classifies: marble, granite, slate, limestone, terra cotta, and pavers. Understand that marble is made from calcium, just like your teeth and it needs to be cared for properly. Most mineral surfaces are porous and act like a sponge in the presence of moisture and fluids. Since most natural stones are by no means impervious to staining, a penetrating sealer should be applied for protection. However, even when sealed, some natural stones are still susceptible to staining. It is vital to maintain natural stone in accordance to stone care recommendations.

  • Natural Stone should be sealed with sealer at least once a year.
  • Always maintain stone with clean rayon mops, sponges, towels, or rags.
  • Replace old mops, towels and rags frequently because they lose their cleaning ability as they age.
  • Always remove loose debris from stone surfaces to prevent scratching.
  • Pick up spills immediately to prevent staining and etching.
  • Use coasters under drink glasses to help prevent glass rings from occurring.
  • Popular products that damage stone surfaces: Juices, shaving cream, alcoholic beverages, soda, perfume/cologne, nail polish remover, ketchup, mustard, vinegar, cooking oil, supermarket cleaning chemicals, dishwashing soap, hair perm chemicals, shampoos, and body soaps that contain EDTA, rock salt, sand, toothpaste, drain openers, toilet bowl cleaners, and any fluid that contains an acid or alkai.
