Over time, microfiber towels collect and hold onto wax and polish residues, dirt, dust, and other deposits that can decrease their effectiveness. You'll also notice your towels won't absorb as well and aren't as soft as they used to be. Add 2-4 ounces when you launder your microfiber towels and cloths (wash separately from other fabrics). To clean pads, spray the cleaner on the pad, let it soak in, and then rinse with warm water. (35 ounce bottle does not include sprayer).
