Step 1

Wet the stone surface and spray it with a mild, liquid-based soap to help loosen any buildup from water or pet use. Using an abrasive sponge or cleaning brush, scrub the surface in small circular motions to lift residue and refresh the stone’s natural texture. Rinse thoroughly with clean water, and repeat as needed until the surface looks clean and even.

Step 2

For stains or discoloration, dampen the area and lightly sand it with a medium-grit sandpaper in a well-ventilated space. This will smooth the surface and restore the stone’s quick-drying, odor-resistant qualities. Allow the stone to dry completely before using it again.
