When it comes to window awnings, regular maintenance is crucial for keeping them looking and performing their best. Awning maintenance mainly consists of routine cleaning, which prevents dirt from becoming embedded in the fabric. In addition to regularity, however, it’s important to use correct procedures when cleaning an awning. 

After brushing off any loose dirt, apply a cleaning agent, which can range from a mild detergent or dish soap to a solution of vinegar or ammonia. Apply the solution with a sponge or soft bristle brush. If there are a lot of stains, add a little bleach or ammonia to the solution—it won’t hurt the acrylic fabric.

When cleaning an awning, it’s important to be careful of the stitch line, which sits on top of the fabric. The threading can break if you scrub it too vigorously, so either scrub gently or go around it. 

After scrubbing, allow the cleaning solution to sit and soak in the fabric for several minutes before rinsing. While a thorough rinsing is important, using a pressure washer is discouraged because it can be too harsh on the fabric. After cleaning, allow the awning to air dry completely before returning it to its place.
