Swear to God. Just use cold and a good mild detergent. The Vinegar cleans all the sweat and grunge out. Cold keeps colors from bleeding. He recommends you take it to a laundry mat to do it for their commercial machines. You want the front loader where the door seals. Gentle regular wash. Take it home, lay it out and it will dry fast. When it's almost dry, it rubs the lotion on. When it's all dry, take a dry terry cloth and buff the whole thing out. Comes out beautiful!
