Cleaning Your Mabu After every use, rinsing out the Mabu under water removes contaminants that can incubate bacteria and foul odors... NO more sour dish cloth smells haunting your kitchen sink! Any discoloration usually disappears with a short soak in detergent water...fresh and white again! Wring out and hang, or lay flat to dry in a well ventilated place. The Mabu stays soft, clean and white. For convenience your Mabu can be run through the washing machine but may shrink moderately and may wear faster.
