Its secret is that unlike other detergents designed to leave brighteners, fragrances, and other residue behind, ZERO Residue Sport-Wash rinses completely. Nothing is left on your clothing to clog the pores of your fabric. Cotton, wool, and synthetic materials are 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.
