This may seem like a tedious and time-consuming task. However, doing these small steps often will make cleaning easier.
Every month, brush both sides of the awning fabric with a soft-bristled brush.
If you have trees around your awnings, be sure to trim them, as well as clean off any animal droppings, debris and sand from those overhanging trees as soon as possible.
When doing a deep clean, avoid using harsh rubbing as it can damage the surface of the fabric.
When dealing with stubborn stains, leave a warm wet sponge on the area for a short period until the area softens.
Clean your awning when it is less humid, especially at the coast. Humidity tends to encourage mould to appear.
Refrain from using solvents, alcohol or abrasive cleaning products. A light cleanser is sufficient enough to get rid of stains.
Be careful when using a power washer, rotary brush or steam cleaners. These might have long-lasting effects on the fabric of your awnings.
After cleaning, be sure to retract your awnings only after they are dry.
