Abstract
The invention involves a method and compositions for cleaning all oily, natural or synthetic stains or residue from any stone surface, natural or man-made. The method comprises surrounding the stain with a container which is open at the bottom, pouring in a solvent material, covering the container with an airtight lid to prevent evaporation and allowing the solvent to remain on the stain for from 1 to 24 hours. Thereafter the lid is removed and an adsorbent powder is added to the container to the top of the absorbent liquid. The absorbent powder is allowed to stand for 1 to 24 hours and then the powder is removed and the surface being cleaned is allowed to air dry for 24 hours.
