Bucas Rug Wash is ideal for use on waterproof, water repellent and breathable blankets and fabric. The chemicals in detergent can break down the composition of the fabric with each wash, stripping it of its waterproof coating. Bucas’ special phosphate-free formula helps maintain the integrity of your blankets and fabrics while disinfecting and cleaning. For a full guarantee on Bucas blankets, ONLY Bucas Rug Wash should be used. Bucas Rug Wash is not harmful to the environment.
