In general, waterproof PVC or PU coated garments can be cleaned using mild soap and water with a soft brush, then hang to dry. Do not use bleach.
The best way to clean the waterproof breathable raingear is with a product called Techwash from NIKWAX. This product is designed to clean your raingear and also to revitalize the water repellency. After you have had your raingear for a period of time you will find that the water doesn't bead up like it did when it was new, NIKWAX products will bring that feature back. CAUTION: NEVER USE HIGH OR MEDIUM HEAT SETTING IN CLOTHES DRYER TO DRY YOUR GEAR, USE LOW HEAT OR AIR SETTINGS ONLY.
