Carpet protector is a product that is applied to carpets to protect them from dirt, dust, spills, and wear. It forms an invisible barrier on the carpet fibers that repels liquid, or helps it bead up so it can be easily wiped away. Carpet protector also helps limit the amount of staining that occurs due to spills and dirt. It helps keep carpets looking newer for longer by slowing the accumulation of dirt and dust. Most carpet protectors are clear, odorless, colorless, and non-toxic.
