To maintain your soapstone, use a damp cloth or sponge with cleanser for daily cleanings when needed.
Oiling will enhance the luster and the color of the stone, and restore the brand new look once again. Subsequent coats should be reapplied monthly.
Most all scratches will disappear with a direct dab of mineral oil. To permanently remove a deep scratch, apply medium pressure to a scratched area with 80 grit sandpaper. A sanding sponge is recommended. The deeper the scratch, the more sanding will be needed.
After the scratch has been sanded out, you will need to apply a light coat of mineral oil to the sanded area. The mineral oil application should be repeated 2-3 times over a 2-3 day period to match the coloration of the rest of the stone.
