Fabric protector is a treatment applied to textiles to help repel stains, dirt, and moisture. It creates a protective barrier on the surface of fabrics, making it easier to clean and maintain their appearance. Commonly used on upholstery, carpets, and clothing, fabric protectors can extend the life of these items by preventing damage from spills and wear. These products often contain chemicals that bond to the fibers of the fabric, such as Teflon or silicone. While fabric protectors can be effective, it's important to follow the manufacturer's instructions for application and reapplication to ensure optimal performance.
