Scotchgard protector is used on all types of carpet and upholstery. It is designed to form a barrier between dirt and your carpet and upholstery fibers.  It helps to keep stains from permanently staining the material.  It also suspends liquids and solids if they are spilled which gives you extra time on cleaning up the spills. When liquids are spilled onto carpet or upholstery they typically soak right into the material.  If the material has been scotchgarded then the liquid will actually bead up on the material instead of soaking directly into your carpet or upholstery.  Protect your investment and have your carpet and upholstery scotchgarded directly after it has been professionally cleaned.  It's worth it!
