Protects upholstery, draperies, clothing and fabrics from both oil- and water-based stains. This OMS-based formula is safe on the most delicate fabrics: cotton, rayon, acetate, suede, velour and silk. The exclusive blend of fluoro-chemical resins wonâ€™t change the feel of the fabric. Carpet Guard may be applied immediately after wet or dry cleaning on wet or dry fabrics. Furniture may be used as soon as itâ€™s dry.
