Cleaning and Caring for SunbrellaRegular maintenance is the best way to keep your Sunbrella fabrics looking good and delay deep, vigorous cleaning. Brush off dirt before it becomes embedded in the fabrics, and wipe up spills as soon as they occur. For light cleaning, use a mild soap and water solution and a sponge, allowing your cleaning solution to soak into the fabric. Rinse thoroughly to remove all soap residue and allow fabric to air dry. Sunbrella fabrics have been tested to provide up to 98% UV protection, depending on depth of color. Whites and lighter colored fabrics provide less protection than darker fabrics. This protective factor is inherent to the product and will not diminish through use or exposure to the sun. Sunbrella furniture and umbrella fabrics have been awarded the "Seal of Recommendation" by the Skin Cancer Foundation, an international organization dedicated to the prevention of skin cancer. Beautiful and protective fabric is the hallmark of Sunbrella.
