If your carpet is subjected to constant wear and tear, it can become dull and colorless over time. Vanish Carpet and Upholstery Care Foam is designed primarily to treat stains and dirt build-up in carpets, especially in high-traffic areas of your home, such as hallways, stairs and entryways. The foam is easy to use and works deep into your carpet, removing dirt and stains and leaving the carpet clean and smelling fresh. Important: Do not use Vanish Carpet and Upholstery Care Foam with wet hands. Always check the color fastness on an inconspicuous area of the carpet first.
