Grosfillex commercial grade outdoor fabric when tested for fade resistance in compliance with ASTM G 53.96 standard, provide twice the recommended performance of the American Casual Furniture Fabrics Association (ACFFA). Grosfillex commercial outdoor fabrics are naturally stain resistant. To maintain their beauty and ensure long life, wipe up spills with an absorbent cloth as quickly as possible. Clean regularly with a warm water, mild soapy solution.  Rinse thoroughly with clear water to remove all soap and allow to air dry. The fabrics do not promote the growth of molds or mildew.  However, dirt or standing water will support these organisms.  Do not use pine oil cleaners.
