Make a solution to remove stains on your Sunbrella.

• Shake or wipe off any loose dirt.
• Prepare a cleaning solution of 15 ml of mild detergent, such as Woolite or Dawn dishwashing liquid, per litre of lukewarm water (2 fl oz or 1/4 cup to the gallon).
• Use a sponge or a soft bristle brush to clean.
• Let it work for a few minutes. 
  Allow the cleaning solution to soak into the fabric.
• Rinse thoroughly to remove all detergent residues.
• Allow the fabric to dry naturally.
  Sunbrella dries very quickly in the open air. Machine drying is not necessary.
