Bleaching polyester requires the use of an oxygen-based bleach. Fill a wash basin or washing machine with cool water and an oxygen-based bleach. Follow the package directions of the bleach to find out the necessary ratio of water to bleach. Submerge the fabric in the water, and let it soak overnight. The next day, drain all of the water. If the item is not bleached enough, repeat the process.
