Wipe the sponge holder with a damp cloth or sponge regularly to remove any dirt or grime. Avoid using abrasive cleaners or materials that could scratch the surface. After cleaning allow the sponge holder to air dry completely before placing it back in the sink area. This helps prevent mold and mildew growth.
While diatomite is highly absorbent, prolonged exposure to excessive moisture can degrade its quality over time. Try to keep the sponge holder as dry as possible when not in use.
Avoid using strong cleaning agents or solvents that could damage the sponge holder.
