Washing your wet-weather clothing and equipment with regular laundry detergent will compromise the durable water repellent (DWR) finish, causing the fabric to "wet out" in damp conditions. NIKWAX® Tech Wash® is the safe way to clean and refresh waterproof fabrics; it maintains the DWR finish and can even revitalize compromised fabrics. You should be able to use Tech Wash® 5-6 times before re-waterproofing.
