Once mildew appears on your canopy, there is not much that can be done to get rid of it. But you can prevent it from getting worse. Make sure to clean your tent well and it is completely dry before storing away. Most mildew begins when the fabric is stored away wet. Any damage caused by mildew is usually not covered under warranty.

To wash a canopy top, place top on the frame at lowest setting and rinse down with garden hose. Take a mild detergent and use a soft brush for soiled spots. Do not brush graphics. Allow the top to dry completely before storing.
