For more stubborn cases: Soak the fabric for approximately twenty minutes in a solution of no more than 1/2 cup (4 oz.) of a non-chlorine bleach and 1/4 cup (2 oz.) natural soap per galon of water at approximately 100° F. Rinse thoroughly in cold water to remove all of the soap.
Note: Excessive soaking in non-chlorine bleach can deteriorate sewing threads, this method of cleaning may remove part of the water repellency and the fabric should receive an application of an air-curing fluorocarbon water repellent treatment, such as 303 HiTech Fabric Guard, if water repellency is a factor.
Our fabric is made from 100% solution dyed acrylic fiber which is thermoplastic, do not subject to excessive heat. When fabric is stored, it should be cleaned, allowed to air dry, and stored in a dry, well ventilated area.
