Oil Stain on Black Granite

Oil Stains on Granite can be very frustrating to remove. On honed Black Granite it can be particularly difficult. Here are several options that can help to remove oil stains from all colors of granite. I always suggest starting with the least aggressive option, and graduate to more difficult and aggressive options.

The process below (Option 1) can also help with White Water Spots on Black Granite.

Option 1: Fresh Subtle Stains

Use a Professional Stone Cleaner like HMK R55 Intensive Cleaner.

1. Mix 1-Part R55 with 1-Part warm water in solution. Pour over stained granite and allow to dwell on surface for 15 minutes.

2. Scrub with medium stiffness scrub brush for 5 minutes. Soak up solution with a sponge and triple rinse using clean water.

3. Allow to dry for several hours. Repeat process if necessary.

This method is for fresh stains that have not penetrated deeply. This gentle method will not harm the granite, but if you have used a water based sealer, you should re-seal once stain has been removed.

Option 2: Deeper Stains That Have Been There for Some Time

You will need two products for this process; HMK R54 Stain Remover and HMK R55 Intensive Cleaner.

1. Pour R54 directly on Oil Stain, making sure entire stain is fully covered with cleaner. Allow to soak in for 10-15 minutes. Do not allow to dry on surface.

2. While waiting, mix a solution of R55 Intensive Cleaner as in Option 1 above.

3. Wipe up R54 Stain Remover with paper towels, and immediately follow by applying the R55 solution to area.

4. Scrub area vigorously with a sponge or scrub brush. Add more R55 solution to area to keep saturated. Allow to dwell on surface for 10 minutes. Do not allow solution to dry on surface. Add more R55 solution if needed.

5. Sponge up solution and rinse with clean water until no suds remain.

6. Rinse again with clean water. Allow to dry for several hours.

Observe to see if stain has been completely removed. If residual stain remains, repeat process again. If stain persists after two applications you will need to use a Stain Removing Poultice to draw out stains. See Option 3

Option 3 Poultice Extraction Method

For this process you will need two products; HMK R52 Stain Removing Poultice, and HMK R55 Intensive Cleaner. See Combo Pack

1. Mix solution of HMK R55 as in Option 1 and pour over stain.

2. Allow  R55 solution to dwell on surface for 15 minutes. Sponge up solution. No rinsing required at this point. Wipe dry with paper towels and immediately apply poultice.

3. Using  a plastic putty knife, apply R52 Poultice to completely cover stain, making sure that poultice is 1/4″ thick. Cut a piece of plastic wrap that is four times the size of the poultice and cover R52 Poultice and tape down edges of plastic with blue painters tape. Allow to dry overnight.

4. Remove dried poultice with plastic putty knife.

5. Apply solution of R55 and allow to dwell over area for 10-15 minutes.

6. Scrub area with scrub brush or sponge. Soak up solution completely.

7. Rinse, Rinse, and Rinse again with clean water. Allow to dry.

Observe to see if stain has been completely removed. If residual stain remains, repeat process again. If stain persists, contact Torin Dixon for additional options: 800-380-6881

These three options will take care of 95% of all stains that occur in granite. There are some stains that may be impossible to remove if they have penetrated the granite deeply, or have set for a long period of time. There are some instances where you do not know what the source of the stain is. These types of stains may require the use of color enhancing impregnators to blend in the dark stained areas with the light areas.

All granite should be Protected using Professional Grade Impregnators or Sealers.
