Instant carpet stain remover plus deodorizer leaves no sticky residue, so your carpet stays clean, fresh and soft. It is safe for all carpet types, including nylon and other synthetic carpets, as well as stain-resistant carpets. Special surfactants penetrate deep into the carpet fibers to break up and eliminate dirt, grease, odors and stains. Special polymers repel dirt and stains so next time it's easier to clean.
