Frequently Asked Questions

Q: What makes diatomaceous earth coasters better than regular coasters?

A: Diatomaceous earth coasters are made from natural diatomite stone, which has a highly porous structure that absorbs moisture 2–4 times faster than cork or fabric coasters. They dry almost instantly, resist odors and stains, and require no special cleaning products — just a light sand with the included sandpaper to renew absorbency.

Q: How do I clean and maintain my diatomite coasters?

A: Maintenance is simple — if the surface becomes less absorbent over time, lightly sand the coaster with the included sandpaper to open up the pores and restore its quick-dry performance. For everyday cleaning, wipe with a damp cloth and allow to air dry fully before next use.

Q: Are these coasters suitable for outdoor use?

A: Yes! These diatomaceous earth coasters are versatile enough for both indoor and outdoor settings. Use them on patios, garden tables, or poolside surfaces. Their silicone non-slip pads keep them stable on a variety of surfaces, and their stone aesthetic looks great anywhere.
