Can I heavy clean Sunbrella outdoor fabrics that have stubborn stains and mildew?
Sunbrella fabric does not promote mildew growth, however, mildew may grow on dirt and other foreign substances that are not removed from the fabric. To clean mildew, or other stubborn stains: • Prepare a solution of 8 ounces (1 cup) of bleach and 2 ounces (1/4 cup) of mild soap per gallon of clean water. • Spray on entire area and allow to soak into the fabric. • Scrub vigorously with a soft bristle brush, sponge, or clean towel. • Rinse thoroughly to remove all soap residue. • Allow fabric to air dry. If stain and/or mildew are severe, bleach quantities may be increased. For removable Sunbrella fabric umbrella and cushion covers, machine wash in cold water (less than 100°F/38°C). Depending on wash load size, use normal amounts of mild laundry soap and add 1 cup of bleach. Allow fabric to air dry.
