How To Revive A Dull Granite Countertop

If you have a dull granite countertop, you don't have to replace it. A polishing job will restore its natural shine, and save on the cost of replacement. Granite is commonly maintenance free, but acidic substances or soap scum can eventually damage the surface,

A novice DIY person should be able to polish the countertops. Here are tips to polish dull granite countertops.

Prepare to Work

For this project, you need:

  • work gloves
  • sponge
  • soft cloths
  • felt pad
  • small bowl
  • spray bottles
  • baking soda (optional)
  • mild liquid dish soap
  • rubbing alcohol (optional)
  • granite-safe polish
  • granite sealer

Wipe the surface with the granite cleaner and a soft sponge. If you prefer a natural cleaner, mix a small amount of liquid soap in warm water. Shake well, and spray the countertop. Let the cleaner stand a minute or two, then use a clean cloth or sponge to rinse.


For non-scratched surfaces that just look dull, rubbing alcohol is enough to restore the shine Combine a 50:50 ratio of rubbing alcohol and warm water in a spray bottle.

Mist single sections of the countertop with the solution, and use a cloth to rub it in the surface. Avoid using any cleaner with ammonia, citrus, or vinegar, because acid may strip the finish. Dry the area quickly with a clean cloth

For light surface etching, a polishing powder from a home and garden center may work. The substance works to remove stains and light scratches. Polishing powder may not be suitable to use on all granite surfaces, so consult your manual to ensure it is safe for your countertop.

Mix enough powder with water in a small bowl to form a paste. Work it in the surface using the felt pad in a circular motion. Rinse according to directions.

To make a natural cleaner, make a paste from a quarter teaspoon of baking soda and three cups of warm water. Stir lightly, then buff it with a cloth, then rinse using a fresh cloth moistened in warm water.


It is important to seal granite countertops to protect the finish, since granite is porous.Test the finish for proper sealing by pouring some water on it. Beading water indicates the surface doesn't need anymore work.

Apply sealer, if the water seeps in the surface. Spray the sealer on a hidden area to test reaction. Apply the sealer in small sections, and rub it with a cloth for five minutes, or until the countertop dries.

Allow the sealer to stand about thirty minutes, or follow instructions for the suggested time. Try the water test again, and apply another coat of sealer, if needed.
