How to Clean Mildew From an RV Awning

by Diane Dilov-Schultheis

Recreational vehicles (RVs) are a great means of traveling. You can take an RV just about anywhere you want to go. There is regular maintenance required to keep your RV looking its best. One of these chores is cleaning mildew from the awnings. Mildew is a common problem associated with awnings. It will just get worse if not properly cleaned off. It can be removed with a few items, a little effort and your time.

Gather your supplies. Decide if you want to use mildew cleaner or bleach. Either will work. If you use bleach, dilute it with water from a spray bottle.

Lower the RV awning enough to reach it easily. Use a ladder, if necessary. Spray it with the water hose.

Spray the mildew cleaner or the bleach on the awning. Use slow sweeps and start at the top. Cover it thoroughly.

Use a brush to spread the cleaner on the awning. If the awning is too high, use an extender handle on the brush or a ladder. Let it sit for at least 10 minutes.

Use the hose to rinse the cleaner off. Spray it from the top down. Repeat.

Repeat Step 3 through Step 5 on any areas of the awning needed. It may take more than one cleaning, depending on how much mildew is there.


  • check Remove anything located below the awning that could be affected by the mildew cleaner, bleach or water being used. Wear rubber gloves to protect your hands, if desired.


  • close Do not use pressure on the awning when you are brushing it. You do not want to tear the fabric. You can use a pressure cleaner or power washer, but it is not recommended. Using one could easily cause a tear in awning material.
