Diatomaceous earth is a naturally occurring mineral valued for its fast-drying, highly absorbent properties. Free from harmful chemicals, its porous structure draws in moisture on contact and encourages rapid evaporation, reducing lingering dampness and creating an environment less conducive to mold, mildew, and odors. The result is a cleaner, drier surface that is easy to maintain.

Step 2

Use an abrasive sponge or cleaning brush to scrub the surface in small circular motions. Focus on any areas with visible buildup or discoloration. Rinse thoroughly with clean water, and repeat as needed until the surface looks refreshed and free of residue.

Step 3

Repeat the same cleaning process with the rubber bases. Scrub them using soap and water to remove any buildup or residue, then let them dry completely.

Step 4

For deeper stains, dampen the affected area and sand it lightly with a medium-grit sandpaper in a well-ventilated space. Wipe away dust and residue, then allow the stone to dry fully before using it again. This ensures it maintains its quick-drying, mold-resistant performance.
