How to Clean RV Awning | Done Right in 6 Steps

An RV awning takes a beating from rain, tree sap, bird droppings, and UV rays. The wrong cleaning method can stain or damage the fabric; the right one keeps it looking new and extends its life by years. Here is the exact procedure that works for both vinyl and acrylic awnings, with the timing and tools you need.

What You Need to Clean an RV Awning

The supplies are simple. The table below covers the standard mix and stronger option for mold and mildew.

You also need a 5-gallon bucket, a soft-bristle brush, a garden hose with a low-pressure nozzle, a sturdy ladder, and optionally a spray bottle for spot-treating. If you are shopping for a dedicated product, see our tested roundup of the best cleaners for RV awnings for options that cut through grease and oxidation.

The 6-Step Cleaning Process

Follow these steps in order. Skipping the soak or drying step is the most common reason for a stiff, stained awning.

1. Extend and Pre-Rinse

Extend your awning fully. Spray both surfaces with plain water to remove loose dirt and prevent grit from grinding into the fabric when scrubbing.

2. Scrub With Your Cleaning Solution

Mix your chosen solution in the 5-gallon bucket. Dip a soft-bristle brush and scrub the entire awning in sections, paying extra attention to fold lines and the roller area. For sap or droppings, apply solution directly, let sit for 5 minutes, then scrub gently.

3. Roll the Awning and Let It Soak

Without rinsing, retract the awning so the soapy fabric rolls against itself. Let it sit for 5 minutes for a standard clean, or 30–60 minutes for stubborn stains, mold, or mildew. This penetrates the fabric and breaks down embedded dirt.

4. Re-Extend and Scrub Again

Extend the awning fully again. Scrub the entire surface one more time to lift dirt the soaking step released.

5. Rinse Thoroughly

Rinse both sides until the water runs completely clear. Pay attention to the underside to avoid soap residue that attracts dirt. If using a pressure washer, set it to the lowest PSI with a fan-shaped nozzle at least 12 inches from the fabric. Never use a concentrated jet—it can puncture the material.

6. Let It Air-Dry Completely Before Retracting

Let the awning dry in the sun before retracting. Retracting a wet awning traps moisture, leading to mildew, fabric rot, and a musty smell. On a sunny day, this takes 1–2 hours. When dry to the touch with normal color, you can safely roll it up.

What Not to Do

Never retract a wet awning. Never use bleach at full strength or mix it with ammonia. Never scrub with wire brushes or abrasive pads. Never apply heat (no hair dryers or heat guns). Never pry off roller end caps. Never use harsh cleaners like oven cleaner, acetone, or mineral spirits—they can dissolve the waterproof coating on vinyl awnings.

How Often Should You Clean It?

Hose off your awning once a month during camping season with plain water. Acrylic awnings like Sunbrella benefit from a commercial-grade fabric guard after cleaning. Vinyl awnings should get a surface protectant to shield them from UV fading.
