Unlike commercial bath mats or dish racks, the Dorai Diomat cleans itself. It utilizes rapid drying that dissipates moisture and eliminates mold.
Similar to light colored towels or sheets, darker liquids or self tanners can cause some staining if absorbed into the mat. Lighter liquids will not typically stain your mat. In the event that your mat gets stained, it can be cleaned in two ways. For light stains or scuffs, use the included sanding tool to gently rub off any marks. For more extreme stains, small amounts of bleach or hydrogen peroxide will do the trick.
