Shade Sails can become dirty over time. To clean your shade sail, disassemble and apply a mild detergent solution with a sponge or very soft bristle brush. For best results allow the solution to stand for 10 minutes before rinsing off your shade sail with water from a garden hose. We do not recommend the use of a high pressure water blaster to clean fabric. Do not use abrasive cleaners, or place your shade sail in your washing machine, clothes drier, or scrub it with a hard bristle brush or scouring pad.If you remove your shade sail for storage, ensure that it is completely dry and stored in a dry place. Preferably in a protective storage bag.
