This 100% Wool Dish Drying Mat is an all natural alternative to microfiber dish mats. It catches water drips as your dishes dry and keeps your dishes cushioned from your counter. Naturally antimicrobial, wool is capable of easily absorbing moisture and then evaporating it over time. To care for your mat, periodically lay it out in direct sunlight, turning it over to the opposite side after an hour. If full washing is needed, gently submerge in warm water with a tiny bit of soap.
