Our carpet foam cleaner contains glycerin and sodium cocamyl glycine. It can effectively remove stains, oil stains and odors on the carpet, and make the carpet look new. Its use method is very simple: 1. Spray the cleaner directly on the stain, making sure to cover the stained area. 2. Gently wipe with a damp towel and repeat until the stain is completely removed. 3. Wipe off excess water with a clean paper towel and allow the surface to dry naturally. The fine foam penetrates deep into the fibers to thoroughly clean dirt and protect the carpet material.
