Cap washer prepares billed hats for a good bath in the dishwasher! Renew cherished baseball and golf hats that are full of sweat stains or other blemishes. Just place a cap in the plastic frame, snap it shut, and insert on the top shelf of a dishwasher. Add soap or detergent for one wash cycle and the cap comes out fresh and ready for action, without being wrinkled or out of shape. Also great for visors or even wool caps.
