Spinster Sisters Diatomaceous Earth Soap Tray

Diatomaceous earth is a naturally porous, sedimentary rock material that acts like a sponge. It absorbs water from the surface of your soap bar almost instantly, wicking moisture away and allowing the bar to air-dry quickly rather than sitting in a puddle.

Because diatomaceous earth is highly absorbent and dries rapidly, it creates an environment where mold and mildew struggle to thrive. However, we recommend occasionally rinsing it with water and letting it air dry in a well-ventilated area to keep it clean and effective.

Yes, it works well with any standard soap bar, including body butter, face serum, and deodorant bars. The circular shape is versatile, though ensure your bar is roughly the same size or smaller than the tray for the best fit.

Very little. If you notice the absorption rate slowing down after several months of use, you can lightly sand the surface with a piece of fine-grit sandpaper to unclog the pores and restore its original performance.

The material has a slightly textured, stone-like feel. While it is generally safe for most surfaces, if you are concerned about scratching delicate countertops, we recommend placing a small felt pad or coaster underneath the tray.
