How to get grease stains out of slate tile

Updated April 17, 2017

Slate can make a beautiful accent to any kitchen. Often it is used as a material for backsplashes behind the sink and ovens. Of course, these can get a little dirty as we cook, clean and simply live. Acid-based cleaners used for other surfaces can damage the texture of the slate and ruin its finish. But with a simple acid-free degreaser and a sponge with a soft side and a scrubby side, you can make your slate look almost like new.

  1. Apply a small dot of Dawn dish detergent to your index finger, and apply the detergent to an inconspicuous area of your slate to test the safety of the product.

  2. Dampen a non-scratch scrub sponge with warm water, and apply about a tsp of soap to the sponge. Work the sponge to make the solution soapy.

  3. Use the scrubbing side of the sponge to work off the grease from the slate. Scrub in a circular motion for best results.

  4. Use a toothbrush to get into small spots and crevices that may be too small for the sponge to get to. Leave the soap on the surface of the slate for 5 to 10 minutes.

  5. Rinse the soap out of the sponge, and then soak the sponge with warm water. Wipe down the tile and remove all the soapy water from the surface of the slate.

  6. Tip

    You can use another brand of dish detergent, as long as it isn't abrasive or acidic.


    Using a rough material, such as steel wool, will damage the surface of your slate and leave scratching.
