RIT White-Wash is a chlorine-free bleach and whitener treatment for dingy white fabrics. The powder is made for whites only, including delicate and non-bleachable whites, and helps remove yellowing, discoloration and stains when used with detergent. It can be used by stovetop or washer methods according to RIT instructions. Do not use on coloured fabrics or whites with coloured trims or prints.
