Febreze cleans away odors trapped in fabrics; it's not a 'cover-up' product. Proprietary cleaning system goes to the source of odors and eliminates them. Spray directly on fabrics until slightly damp. As it dries, odors disappear. Patented binding technology locks on to odor molecules and traps them for good. A light, fresh scent is left behind to leave the treated area smelling fresh and clean. Safe for virtually all fabrics.
