You can clean it yourself or use the services of a reputable professional awning cleaner.

If you clean it yourself, it is important to follow these instructions:

1. If your awning is located in a commercial area, close off the area to customers and pedestrians.
2. Brush off all debris.
3. Clean from the bottom and work up.
4. Scrub the awning and valance with a soft bristled brush.
5. Cover all parts of the awning. Missed spots will show when dry.
6. Rinse the awning completely. Film left on the material will leave marks and a chalky residue.
7. Occasionally rinse your awning down with a garden hose and keep the underside of your awning clean by simply brushing with a clean household broom.
