One of the best ways to keep Sunbrella® fabrics looking good is to brush off dirt before it becomes embedded in the fabrics and wipe up spills or clean up soon after a spill occurs. The quicker you clean spills, the easier they can be to remove.
Blot (don’t rub) liquid spills with a clean, dry cloth. For oil-based spills, apply an absorbent such as corn starch, then remove with a straight edge. Spray on a mild cleaning solution of soap (such as Dawn® or Woolite®) and water. Rinse the fabric thoroughly to remove all soap residue. Air dry.
For tougher stains, prepare a solution of 1/4 cup mild soap per gallon of lukewarm water. Use a soft bristle brush to clean, allowing the cleaning solution to soak into the fabric. Rinse thoroughly to remove all soap residue and allow fabric to air dry.
Sunbrella fabrics do not promote mildew growth, however, mildew may grow on dirt and other foreign substances if not removed from the fabric. To remove mold or mildew, prepare a solution of 1 cup of bleach and 1/4 cup mild soap per gallon of water. Spray on the entire area and allow to soak into the fabric for 15 minutes. Clean the entire surface area with a sponge, clean towel or very soft bristle brush. Rinse thoroughly to remove all soap residue. Air dry
