Can You Pressure Wash an RV Awning?

You just spent an exciting summer in your RV with your family, relaxing under the cool shade of your awning. As you’re breaking down to head home from your last camping trip of the season and you notice that your awning is caked with bugs, dirt, and spider webs from months of use.

Is it safe to clean it using a pressure washer? 

You can pressure wash an RV awning, but you have to be very careful not to damage it. Awnings can be easily damaged, but vinyl materials are especially vulnerable to the extreme power of a pressure washer. If you have a garden hose, consider that before reaching for your pressure washer. 

Of course, we all want to take good care of our awnings because our awnings take good care of us.

This article will explore how to wash your awning with a pressure washer, as well as other tips to keep it in the best possible shape.

Whether you’re a first-time camper or you have done it a hundred times, I hope you learn something from this article.  

Types of Awnings

The most popular types of awnings are acrylic and vinyl.

In particular, vinyl is a great choice for an awning because it is waterproof, fade and scratch-resistant, and blocks UV rays.

However, it attracts dirt and dust and is very susceptible to mold and mildew.

This just means you have to be diligent about caring for it. 

Acrylic is also a fine choice for your awning.

It is typically water-resistant and durable to wind, rain, and sun. However, its woven material makes it difficult to remove dirt and grime.

Cleaning Your RV Awning With a Pressure Washer

Pressure washers make so many tasks faster and more manageable, but their intense pressure can be tough on delicate surfaces.

As I said earlier, using a pressure washer to clean your RV awning is not ideal, but will work in a pinch.

However, please take care not to damage the awning materials with high pressure.

For this process, you will need many of the same materials with which you would wash a car.

To get started gather the following materials:  

  • A pressure washer with low PSI (pounds per square inch) and high GPM (gallons per minute)
  • Some sort of scrubbing brush (soft-bristled for vinyl and stiff-bristled for the acrylic to protect the material)
  • Use an RV awning cleaning solution such as the Thetford Premium RV Awning Cleaner. These RV awning-specific solutions are safe on all materials and keep your awning looking new for longer. In a pinch, you can use two parts water and one part dish soap as well.
  • A large bucket for the cleaning solution

Now that you have all of your materials, follow these simple steps to clean your awning:

  1. Brush off all of the excess dirt and dried leaves. Your awning likely accumulated some extra debris during its use, so make sure that is knocked off, to begin with. Your long-handled brush will make this simple. Don’t forget to use the appropriate brush for your awning materials. This Carrand Deluxe Soft Brush is perfect for vinyl awnings, and this Fuller Brush E-Z Scrubber with stiff bristles will be just right for an acrylic awning. 
  2. Wet the top and bottom of your awning. For this step, remember to use the lowest possible setting on your pressure washer. 
  3. Begin cleaning. Using your long-handled brush, begin gently scrubbing the cleaning solution into the awning. Let it sit for a few minutes, but don’t let it dry. Please note that acrylic surfaces are porous, which makes them a bit more difficult to clean. Keep this in mind as you scrub. 
  4. Rinse. Again, using your pressure washer on the lowest possible setting, rinse the cleaning solution out of the awning. It is best to go from the top down to ensure all of the cleaning solutions get out. 
  5. Allow it to dry completely. This step is vital. Ensuring it is completely dry will keep mold and mildew from growing while it is rolled up. 
  6. If desired, apply protectant following instructions on the package. Protectants will keep it looking newer longer and, most importantly, make the cleaning process easier next time.

As I said earlier, a pressure washer is not the ideal tool to clean your awning because of the high risk of damage to the material.

A safer option would be to use a garden hose instead.

While these are specific instructions for cleaning your awning with a pressure washer, you can use these steps as a guide, but substitute a garden hose for the pressure washer. 

How Frequently Should You Clean Your Awning? 

The answer to this question depends heavily on how frequently you use it.

If you are a seasonal user, once per year should do the trick. Typically, you want to do this at the end of your camping season as you begin to prepare your RV for winter.

It will have collected tons of dirt, bugs, and other grime over the summer.

Now, if you live in or use your RV year-round, you should plan on cleaning it a lot more often.

It should get a quick clean about every 2-3 months, but give it a thorough cleaning at least once or twice a year.

The important thing is to maintain a regular cleaning schedule based on your level of use. 

Additional Ways to Care for Your Awning

While your awning might not be your top priority in terms of RV maintenance, but perhaps it should be up there.

It can cost a fortune to repair or replace it, so it’s important that you properly maintain it.

Taking good care of your awning may ensure that it lasts the lifetime of your RV. 

One easy way to help maintain your awning is to avoid getting it dirty in the first place.

This may seem like an absurd suggestion, but carefully choosing where you park your RV could have a major impact on the lifespan of your awning.

If it’s parked under a sap tree, for example, that will make it particularly difficult to clean.

Vigorously scrubbing sap off of your awning, puts it at high risk of scratches, rips, and overall wear. 

There are a lot of great products that help maintain your awning.

Fabric protectants are widely available, affordable, easy to use, and extend the life of your awning.

If you have a vinyl awning, 303 Aerospace is an excellent choice. It provides superior UV protection, dust, and dirt repellant and will keep surfaces looking newer longer.

For both of these products, make sure to wait until your awning is completely dry before applying them. 


The overall message in this article is simply to take care of your awning.

They can be extremely expensive to repair or replace. Maintenance is relatively simple.

It is worth the time and energy to keep your awning a lifetime.

Taking proactive measures such as regular cleaning schedules to protect your awning will make cleaning day swift and easy. 

To wrap up, using a pressure washer to wash your RV awning is perfectly acceptable.

Just remember that some materials (especially vinyl) can be quite vulnerable to damage from such high water pressure.

However, using a regular garden hose will significantly reduce this risk, and it is just as simple.
