How To Remove Stains In Granite

How To Remove A Stain From Your Granite Countertops: A Demonstration By Great Lakes Granite & Marble

Since granite and other natural stones are porous, many experts recommend treating these countertops with a penetrating sealer. Even treated tops, though, may get stains occasionally. The good news is, there are few to no substances that cannot be removed using the proper cleaning agent and process. Follow these steps to create a poultice to remove stains from porous materials.

Ingredients Needed:

1. Wicking Chemical
2. Absorbent Base
3. Tape
4. Wax Paper
5. Stir Stick
6. Plastic Putty Knife

Wicking Chemical:
For Food Stains-Hydrogen Peroxide
Oil Stains- Dish Detergent
Biological Stains (mold, fungus, mildew)-Bleach

Absorbant Base:
Choose One- Flour, Dry Clay, Saw Dust, Paper Towel


Always tests the poultice on an inconspicuous spot on the counter top
before applying it to the stain.

1. Prepare the poultice. Mix your wicking chemical with your absorbent base. Stir the Ingredients. Your paste should be the
consistency of peanut butter.

2. Cover the stained area with the poultice.

3. Now place the wax paper over the poultice. Add the tape around the edges. Pat the poultice area to allow it adhere to the stone.

4. Now leave the poultice in place for 24 hours.

5. Now scrape the remains off the counter. Once the poultice is dry, its useful life is over. Next wipe the surface with a dry paper towel. If there’s a ring around the newly cleaned area, it’s residual moisture that should evaporate within a few days.

If you still see the stain, you may need to apply the poultice more than once to remove the stain.

Remember, there is not a stain that cannot be removed from your granite counter tops.

If you can not removed the stain with your poultice, call your stone fabricator.
