Sport-Wash is safe for all washable fabrics, and yet powerful enough to remove odors and your toughest stains such as soil, blood, and grass. Its secret is that unlike other detergents designed to leave brighteners, fragrances, and other residue behind, Sport-Wash rinses completely. Nothing is left on your clothing to clog the pores of your fabric. Cotton, wool, and synthetic materials and left completely clean. Insulation like down, Thinsulate, and Hollofil fluff up for maximum warmth. And even difficult to clean sportswear materials such as Gore-Tex have their waterproofing and breathability restored.
