Diatomaceous earth, or grass of the sea, is a naturally occurring mineral that is made from the fossilized remains of tiny aquatic organisms. You can learn more about our instant-drying technology on the How it Works page.

Diatomaceous Earth is antimicrobial by its physical properties not through the use of any chemicals or toxins. In its raw state, the material attracts and binds bacteria and parasites, causing them to dry out and die.

When compressed into boards it still rapidly evaporates to help prevent mold but doesn't hold the same antimicrobial properties as the raw material.

In the event that your mat gets stained, it can be cleaned in two ways. For light stains or scuffs, use the included sand paper to gently rub off any marks. We recommend doing this in a well ventilated area. For more extreme stains, small amounts of bleach or hydrogen peroxide will do the trick.

Diatomaceous Earth is a white algae substance that is broken down into small pieces, so white spots occur naturally in the production process. Some larger pieces remain during this process. We hope you appreciate the natural substances and understand that some white algae pieces will remain visible on the dark surface.

Due to its porous nature, marble and other natural stones are sensitive and prone to discoloration or staining, especially when not sealed. We do not guarantee Dorai products like our quick-drying bath mats on these surfaces. For more information click here.

We're glad you asked, we hope this is the last bath mat you ever need to buy.

Dorai Bath Stones are meant to be durable, but on rare occasions, they can break with enough force or weight. To prevent this we advise always having the foam pad in place between the floor and the mat.
