“Our granite countertops are almost 2 years old. Our kitchen counter has an extended area that we use for eating. This area has darkened around the edges where our arms and hands rest on it during meals. What is the best way to lighten that area (remove oil stains) Thank you for your help”


Granite and other natural stone surfaces are absorbent. Some granite, particularly lighter colors, are more absorbent than darker colors, and over time they will get darker where we often touch it with our skin. The oils in our skin as well as lotions used may come in contact with the stone and darken it. This condition needs a Deep Cleaning.

We always recommend the least aggressive solution first, then graduate to more aggressive options as needed. Please see the following steps:

clean granite

Perform the Deep Cleaning using our HMK R155 Intensive Cleaner. Despite the name, it is a very safe cleaning product for all stone, but it does wonders. Mix a solution of 1-part R155 to 5-parts warm water. Soak a cloth in the solution and cover affected or stained area with the saturated cloth and allow to soak in for 15 minutes, re-soaking the  cloth every 5 minutes. After 15 minutes, scrub area with a scrub-pad, then rinse very well. Allow to dry, then observe effectiveness of the process. Repeat as needed.

For stubborn stains, or deeply imbedded stains, you may need to use a poultice to draw-out the stain. We suggest using our HMK R152 Stain Removing Poultice.

granite poulticeThis¬†poultice uses a chemical reaction in the paste to draw out the stains as it dries. I have found for best results perform the Deep Cleaning process first, then immediately apply a layer of the R152 paste, 1/4″ thick over stained area and cover with plastic wrap, taping down the edges. This process allows the poultice to dry much more slowly, to draw out the stains. It may take 2 days for the poultice to completely harden. Scrape off the poultice with a plastic spatula or puddy knife then immediately wash area with the R155 solution. Rinse very well (the R155 is very concentrated) and allow to completely dry. Observe results. Repeat if necessary.

These two products have been VERY effective at removing deeply imbedded stains in granite, marble, travertine, limestone and other natural stone surfaces.

remove ink from graniteFor non-organic stains like Ink, Dyes, Fingernail Polish, Mineral Oil, and other non-food oils, we suggest using the HMK R154 Stain Remover prior to using the Poultice.
