In manufacturing, most liquid cleaners start as blends of powders that are dissolved and liquified. Because they start as powders, they dry to powders to leave a dulling film. RX 101 is different. It is a highly concentrated complex of LIQUID surfactants that are completely free-rinsing. It's ideal for all cleaning, but especially for maintenance of "wet-look" floors where it is formulated to penetrate and lift heavy soil without etching the finish or leaving a film. With RX 101 you will use less product, less effort, do a better cleaning job and enjoy an extra bonus of eliminating unpleasant odors.
