Many articles of outdoor clothing and equipment aren't suitable for machine washings. G-Wash Spray Cleaner is a gentle, yet effective cleaner that removes dirt, oils and airborne contaminants without stripping durable water repellency (DWR) from technical clothing and equipment. G-Wash Spray Cleaner is a fast and effective way of cleaning products like down jackets, sleeping bag shells, backpacks and bulky items that may not be recommended for washing by traditional methods.
