Enzyme Prespray is a powerful cleaning partner when used with other detergents that can not remove soils and stains on their own. This product works by breaking down the protein bond that causes soils and stains to adhere to carpet fibers. After bonds have been broken, soils and stains are removed effortlessly and quickly. Grease and oil based stains are no match for this quality product; Enzyme Prespray works immediately to digest grease and oilbinding soils. Enzyme Prespray is quick dissolving, fast acting, pH buffered, and simple to use.
