Microfiber towels accumulate and contain wax and polish residues, grime, dust, and other deposits over time, which can reduce their effectiveness. You\'ll also notice that your towels aren\'t as absorbent or as soft as they once were. When washing your microfiber towels and cloths, add 2-4 ounces (wash separately from other fabrics). Spray the cleanser on the pad, let it soak in, and then rinse with warm water to clean it. (The sprayer is not included in the 35-ounce bottle.)
