EARTHWORM® Family-Safe Carpet & Upholstery Cleaner uses a formula of natural enzymes to penetrate and clean upholstery fabric and carpet fibers. It loosens and breaks down embedded dirt, food stains, pet waste and almost any other organic material. The result is a truly clean, odor-free couch, carpet or favorite chair. It does not leave any chemical residue. Only harmless nutrients and water are left behind.
