If you’ve been wondering how to clean awnings without damaging the fabric, you’re in the right place. A little care goes a long way and with the right technique, you can remove dirt, prevent mould, and help your awning look brand new for years.
You won’t need any fancy tools, just a dry day, a soft brush, a mild soap solution, and a little patience. Learning how to clean awnings properly not only keeps your outdoor space looking beautiful but also protects your investment through every season.
1. Prepare Before You Start: How to Clean Awnings Safely
Before you begin, check the forecast for a dry, still day. Cleaning in windy weather can blow debris back onto the wet fabric and undo your hard work.
Fully extend your awning and make sure the arms are locked in place so it can’t retract while you’re working. Move outdoor furniture and plants out of the way and give yourself room to reach the full surface.
A quick safety note: Never open your awning in windy or rainy weather. Strong gusts or downpours can damage the fabric and frame faster than you’d think. And while wind sensors are handy, don’t rely on them completely- it’s always best to retract your awning manually/with your remote when the weather turns.
2. Brush Away Loose Debris
Before you start learning how to clean your awning, always make sure your awning is locked in place.
Start with a soft-bristled brush or microfibre cloth to remove loose dirt, leaves, and dust. Focus on seams, folds, and the areas where the fabric meets the cassette.
Regular light brushing stops grit from wearing down the fabric and helps prevent tiny tears when the awning retracts.
3. Mix a Gentle Cleaning Solution
For best results, skip harsh chemicals.
Mix lukewarm water with a mild, detergent-free soap. Avoid bleach or anything too strong, as these can weaken waterproof coatings. Always test the solution on a small area first.
There are also many specific awning/waterproofing brands of detergent on the market that could help you, but we would always recommend testing a small area first.
4. Wipe, Rinse, and Dry
When deciding how to clean awnings most effectively, gentle soap and warm water will always beat harsh chemicals.
Dip a soft sponge or cloth into your soapy water and gently wipe the fabric from top to bottom. Work in small sections so dirty water doesn’t drip onto areas you’ve already cleaned.
Once you’ve finished, use a garden hose on a gentle spray setting to rinse away every trace of soap. Let the awning air-dry completely before retracting, this can take several hours on a cool day.
5. Reproof to Protect the Fabric
Deep cleaning can wash away the original waterproof layer. To keep your awning performing at its best, reproof every 2–3 years (or after any deep clean). Choose a fabric-safe reproofing spray and apply it once the material is fully dry.

💬 Common Awning Cleaning FAQs
Can I use a pressure washer?
It’s best not to. High pressure can damage the weave and seams. Stick to a soft hose spray.
Do I really need to reproof?
Yes, reproofing restores the fabric’s water resistance. Aim for every few years or after a major clean.
What’s the best weather for cleaning?
Dry, mild, and slightly overcast. Direct sun can dry soap too quickly, leaving streaks.
Can I clean an electric awning while it’s installed?
Yes, just protect the cassette and motor area from excess water. Wipe those parts by hand with a damp cloth.
