RV Awning Care: Cleaning, Repair, and Storm-Proofing

Our RV awning cost $1,800 to replace. I know this because I destroyed the original one by leaving it extended during what I thought would be a brief afternoon rainstorm at a campground in the Ozarks. The rain was not the problem. The wind that came with it was. A gust caught the awning like a sail, ripped the fabric from both arms, bent one support arm into a pretzel, and dented the side of our RV where the arm impacted. Insurance covered the replacement, but our deductible plus the body work came to nearly $2,500. All because I was too lazy to retract the awning when clouds rolled in.

That expensive lesson turned me into an awning maintenance evangelist. A little regular care keeps your awning functional and attractive for years. Knowing when to retract it keeps it from becoming a $2,000 kite. Here is everything Emily and I have learned about RV awning care, from routine cleaning to emergency repairs. And if you are thinking that this level of maintenance vigilance applies to your whole RV, you are right, our winterization guide covers a similar comprehensive approach for seasonal changes.

Understanding Your Awning Type

RV awnings come in two main fabric types, and the care routine differs depending on which you have.

Vinyl Awnings

Vinyl awnings are the most common type on older RVs and many mid-range models. They are made from laminated vinyl fabric that is waterproof, durable, and relatively inexpensive to replace. Vinyl awnings feel slightly stiff and have a smooth, almost plastic-like surface. They shed water well and are easy to wipe clean.

The downsides of vinyl are that it degrades faster in UV light, tends to develop chalky oxidation on the surface over time, and is more susceptible to mold and mildew on the underside because moisture cannot breathe through the material. Vinyl awnings typically last 5 to 8 years with good care.

Acrylic (Woven) Awnings

Acrylic awnings are woven fabric with a water-resistant treatment rather than a solid waterproof membrane. They are lighter, more flexible, and better at resisting UV degradation. Acrylic fabric breathes, which means moisture can evaporate through the material rather than getting trapped underneath and breeding mold. Higher-end RVs and aftermarket replacement awnings often use acrylic.

The tradeoff is that acrylic is not fully waterproof. In heavy rain, water will seep through eventually. Acrylic awnings are designed for shade and light rain, not for sheltering under during downpours. They also cost more to replace. With proper care, acrylic awnings last 8 to 15 years.

Routine Cleaning: Monthly During Camping Season

Cleaning your awning every month during the season prevents stains from setting, removes mold before it spreads, and keeps the fabric looking good. The process takes about 30 minutes and requires nothing more than a bucket, a soft brush, a hose, and the right cleaning solution.

Cleaning Vinyl Awnings

Extend the awning fully. Mix a quarter cup of dish soap (Dawn works well) with a gallon of warm water. For stubborn stains or mildew, add half a cup of white vinegar. Apply the solution to the top and bottom of the fabric with a soft-bristle brush or a long-handled car wash brush. Scrub gently in a back-and-forth motion along the length of the awning, not across the seams.

Rinse thoroughly with a hose. Do not use a pressure washer, which can delaminate vinyl fabric and damage seams. After rinsing, let the awning dry completely in the extended position before retracting. This is the most important step. Rolling up a wet vinyl awning is an invitation for mold, which brings us to one of the most common RV maintenance mistakes.

Cleaning Acrylic Awnings

Acrylic fabric requires gentler treatment. Use a dedicated awning cleaner or a very mild soap solution (one tablespoon of dish soap per gallon of water). Avoid bleach, which breaks down acrylic fibers over time, and avoid petroleum-based solvents, which damage the water-resistant treatment.

Brush the dry awning first to remove loose dirt and debris. Apply the cleaning solution and let it soak for 10 to 15 minutes. Scrub gently with a soft brush, rinse thoroughly, and let it dry completely before retracting. For serious mold on acrylic, a diluted solution of one cup of bleach per gallon of water can be used sparingly, but rinse extremely well and reapply a water repellent treatment afterward because bleach strips the factory DWR coating.

Dealing with Mold and Mildew

Mold shows up as black or green spots on the fabric, usually on the underside where moisture gets trapped. Once established, mold stains can be very difficult to remove completely. Prevention is much easier than treatment.

The number one cause of awning mold is retracting the awning while it is still wet. After rain, extend the awning at a slight angle to let water run off, wait for the fabric to dry completely (this can take an hour or two in humid conditions), and then retract. If you must retract a wet awning because you are breaking camp, extend it to dry at your next stop as soon as possible. Do not leave a wet awning rolled up for days, it will mold guaranteed.

For existing mold, a commercial awning mold remover works better than home remedies. Products like Mold Armor RV Awning Cleaner or Star Brite Awning Cleaner are formulated for the job. Apply, let it work for 15 minutes, scrub with a soft brush, and rinse. Multiple treatments may be needed for heavy growth. This same kind of proactive cleaning applies to your water system as well, our water system guide covers preventing bacterial growth in tanks.

Fabric Repairs: Fixing Tears and Holes

Small tears and holes do not mean you need a new awning. Vinyl and acrylic fabrics can both be patched effectively if you catch damage early before it spreads.

Patching Vinyl Awnings

For small holes and tears under 4 inches, use a vinyl repair patch kit. Clean the area around the damage with rubbing alcohol and let it dry. Cut a patch from the repair material at least one inch larger than the tear in all directions. Round the corners of the patch to prevent peeling. Apply vinyl cement to both the patch and the damaged area, wait until the cement is tacky (usually one to two minutes), and press the patch firmly into place. Apply pressure with a roller or the back of a spoon, working from the center outward to eliminate air bubbles.

For best results, apply a patch to both the top and bottom of the awning to create a sandwich repair. This distributes stress and prevents the patch from peeling when the awning flexes in wind. Let the cement cure for 24 hours before retracting the awning.

Patching Acrylic Awnings

Acrylic fabric patches differently because it is a woven material. For small tears, use awning repair tape as a temporary fix. For a permanent repair, sew a matching acrylic patch over the tear using heavy-duty UV-resistant thread and a leather needle. Apply seam sealer over the stitching to maintain water resistance. If you are not handy with a needle, an awning repair shop can do this for $50 to $100, which is a fraction of the replacement cost.

When to Replace Instead of Repair

Replace the fabric when tears are longer than 12 inches, when the fabric has become thin and brittle from UV degradation (you can see light through it when you hold it up to the sun), when mold has permanently stained large areas that cleaning cannot remove, or when the fabric has stretched and sags significantly even when properly tensioned. Replacement fabric for most standard RV awnings costs $200 to $500 for the material, plus $200 to $400 for professional installation. It is a fraction of replacing the entire awning assembly.

Mechanical Maintenance: Arms, Springs, and Hardware

The fabric gets all the attention, but the mechanical components of your awning are equally important. A poorly maintained mechanism is harder to operate, more likely to fail, and more dangerous when it does fail.

Lubricate Moving Parts

Every six months, lubricate the pivot points on the awning arms, the roller tube bearings, and the rafter locking mechanisms. Use a silicone-based spray lubricant, not WD-40 (which is a solvent, not a long-term lubricant). Spray each pivot point and work the mechanism back and forth several times to distribute the lubricant. This prevents squeaking, reduces the force needed to extend and retract the awning, and prevents corrosion on aluminum components.

Check Arm Tension and Alignment

The awning arms should hold the fabric taut when extended. If the fabric sags in the middle, the arm spring tension may need adjustment. Most awning arms have an adjustment screw or bolt that increases or decreases spring tension. Consult your awning manual for the specific adjustment procedure because over-tightening can break the spring or damage the arm.

Also check that both arms extend to the same height and angle. If one arm is shorter or angled differently than the other, the awning fabric will be unevenly stressed, which accelerates wear and increases the risk of tearing in wind.

Inspect the Roller Tube

The roller tube is the round tube that the fabric wraps around when retracted. Check it for bends, dents, and corrosion. A bent roller tube will not wrap the fabric evenly, creating loose spots that catch wind and tight spots that stress the fabric. Minor bends can sometimes be straightened by a professional, but a significantly damaged roller tube needs replacement.

Wind Protection: Lessons from Our $2,500 Mistake

Wind is the number one destroyer of RV awnings. A fully extended awning is essentially a large sail, and even moderate wind creates enormous force on the fabric and arms. Our rule after the Ozark incident is simple and non-negotiable.

Retract the awning when wind exceeds 20 mph. No exceptions. If you are not sure about the wind speed, use a weather app or a cheap handheld anemometer ($15 online). If branches are swaying significantly or you can feel the wind pushing against you while standing, it is time to retract.

Never leave the awning extended when you leave the campsite. Weather changes fast. That sunny morning can become a windy afternoon in an hour. We retract our awning every time we leave for a hike, a trip to town, or even a walk to the campground bathhouse. The two minutes it takes to retract the awning is nothing compared to the cost and hassle of dealing with wind damage.

Tilt the awning in rain. When rain is expected, lower one end of the awning so water runs off to one side rather than pooling in the center. Water pooling on the fabric adds enormous weight very quickly, a 10-foot by 8-foot awning with just one inch of standing water holds over 300 pounds. That weight either collapses the awning, rips the fabric, or bends the arms.

Upgrading Your Awning

If your awning is aging or you want better features, here are the upgrades worth considering:

LED light strips: Adhesive LED strips that mount in the awning roller channel provide beautiful ambient lighting under your awning at night. They run on 12V DC and draw minimal power. We installed ours in about 30 minutes and they have transformed our evening campsite experience.

Awning mat or carpet: A dedicated outdoor mat under the awning defines your living space, keeps dirt out of the RV, and is more comfortable underfoot than bare ground. RV awning mats are breathable so they do not trap moisture and kill grass.

Wind sensor (for automatic awnings): If you have an electric retractable awning, a wind sensor automatically retracts the awning when wind exceeds a preset speed. This is the best insurance against wind damage and costs $100 to $200 installed. Worth every cent if you ever forget to retract manually.

Screen room attachment: A screen room that attaches to the awning creates an enclosed bug-free outdoor living space. This extends your usable space significantly and is especially valuable in areas with mosquitoes or flies. Screen rooms range from $100 to $400 depending on size and quality. Pair it with the screen-free family activities we recommend and you have a comfortable outdoor gathering area for the whole family.

Seasonal Awning Care Checklist

Spring (start of season): Extend the awning and inspect the fabric for winter damage, mold, or pest damage (mice sometimes nest in rolled-up awnings). Clean the fabric and lubricate all mechanical components. Check arm tension and alignment. Verify all mounting hardware is tight.

Monthly during use: Clean the fabric, check for new tears or wear, and inspect the seams. Make sure the retraction mechanism works smoothly. Watch for signs of UV degradation on the fabric (fading, brittleness, chalking on vinyl).

Fall (end of season): Do a thorough cleaning and make sure the fabric is completely dry before retracting for storage. Lubricate all moving parts. Apply a UV protectant spray to both sides of the fabric. If your RV will be stored outdoors, consider whether an awning cover or protective wrap is warranted for your climate.

Your awning is one of the most used and most abused components on your RV. Give it a little regular attention, respect the wind limits, and it will provide years of comfortable shade and shelter. Ignore it, and you will learn the same expensive lesson we did in the Ozarks. Trust us, the maintenance is the better option.
