how to remove oil stains on granite

Stain Removal - Oils, Grease, Wine and other food juices can penetrate unsealed granite and marble causing unsightly stains. We have Professional Grade products and techniques to solve the most difficult Stain Removal problem.

To help minimize food and oil stains, follow these directions:

  • mix liquid dish soap and warm water
  • saturate sponge or wash cloth in soap solution
  • cover stained area with sponge or cloth
  • keep stain covered for 30-minutes
  • scrub area with sponge or wash cloth
  • repeat as necessary
  • If stain remains, please see directions below and order Professional Stain Removing products listed below.

Many organic (food & oils) stains can be removed using our R155 Intensive Cleaner as discussed here.

Some Deeply Penetrated stains, particularly Oils, Grease, Wine, and Ink may require a Professional Grade Solvent Cleaner or Poultice Stain Removers. Please see below for more information on these Professional Grade cleaning products for all natural stone surfaces:

 

Step #1 Saturate Stain with HMK R155 Intensive Cleaner 

Mix a solution of R155 1:1 (1 Part HOT Water to 1 Part R155) 

Apply to Stain with a Sponge. Allow to dwell on surface for 15 minutes.

Rinse area with Clean Warm Water and allow to dry. 

If stain remains, use R155 as above, allow solution of R155 to dwell for 15 minutes.

Blot area dry with paper towels and immediately go to Step #2

 

 

Step #2 Cover area with  HMK R154 Stripper Stain Remover

Apply a generous coat of HMK® R154 undiluted onto the dry surface using a stiff brush, scrubbing brush or suitable pad and let soak in. Do not allow to dry. After 10 to 15 minutes, scrub the area again vigorously, applying more R154. Wait for 15 more minutes.

Wipe product off with paper towel and IMMEDIATELY clean the area thoroughly with HMK® R155 Intensive Cleaner, diluted about 1:4 with clean water. Remove the dirty liquid and rinse the area again with clean water. If patches remain untreated after drying, repeat the treatment as necessary.

Using R155 is necessary to Neutralize the Stripper-Stain Remover
and preparing surface for re-sealing and impregnating.

If Stain Persists, you will need to use a Stain Removing Poultice (see below)

How to Remove Extremely Deep Penetrated Stains in
Granite, Marble and All Natural Stone

We recommend using HMK R152 Stain Extracting Poultice

 

 Instructions:

Apply R152 onto the surface with a putty knife or spatula and work into the surface with a brush. 

Thereafter add more HMK® R152 to ensure that there is a layer of at least 1/4" (5mm) of poultice.  Allow to dry for 12 hours. 

Once completely dry brush off the hardened poultice or lightly scrape off using a plastic paint scraper or spatula. Do not be alarmed if stone beneath and surrounding Poultice remains darker for several hours or days. The moisture may cause it to appear darker, but once dry it will return to previous appearance.

After removing all the poultice scrub the area  with HMK® R155 Intensive Cleaner diluted about 1:10 with clean water, using a scrubbing brush, stiff brush or a white/tan pad. Remove the dirty liquid and rinse the area thoroughly with clean water.


For deeply penetrated tough stains a second or third treatment may be necessary.
