If you have polyester clothes that have started to stain, there are a few things you can do to clean them. The first step is to remove as much of the stain as possible. If the stain is on a fabric surface, try using a liquid detergent and water. If the stain is on a garment, try using a cloth or sponge and mild soap. Be careful not to scrub too hard or you may damage the fabric. If the stain is on something else, like carpeting, use a cleaner specifically designed for polyester fabrics. Follow the instructions on the bottle. Once the stain has been removed, rinse the clothing with cold water and dry it off completely. ..
