Assemble all your equipment and supplies before you begin.
Regular RV awning maintenance is essential for extending its lifespan and preventing costly replacements, which can range from $500 to $2,000. A clean awning functions more effectively, improves comfort, and reduces risks from mold, mildew, or pests.
Identify the Awning Type
Different awning materials require different care. Common options include vinyl, acrylic, polyester, canvas, and various coated fabrics. Vinyl typically has a plastic-like shine, while acrylic feels textured and woven. Manufacturer tags or the RV manual usually identify the material. Your awning and slide toppers (if you have them) may be made from different fabrics so check both before heading out to purchase supplies.
Always test cleaners on a small section first before applying them to the full awning.
How to Clean Different RV Awning Materials

Do Use acrylic-safe cleaners; dry thoroughly; apply fabric waterproofing.
Don’t Avoid vinegar, bleach, high-pressure water, or storing damp.
Polyester
Do Use mild soap or diluted vinegar; test cleaners first.
Don’t Avoid harsh detergents, heavy scrubbing, or storing damp.
Canvas
Do Use canvas-specific cleaners; ensure complete drying.
Don’t Avoid bleach, strong detergents, or storing damp.

Wet, then wash the awning in sections so it stays wet when applying the cleaning agents.

A broom handle doesn't reach to the end of our awning so get an extendable handle if you're in the same situation

Lightly sprayed water beads and rolls off the awning so no waterproofing is required at this time.

Exercise extra caution on a wet roof while completely off cleaning agent and any debris that's been loosened. Now to do underneath

It's efficient to do clean slide toppers at the same time.
Optional Waterproofing
If water no longer beads on the fabric, apply a material-appropriate waterproofing spray. This is suitable for vinyl, acrylic, polyester, and canvas. Follow the manufacturer’s instructions and allow proper curing.
Stain Removal Tips
- Mold/Mildew: Use RV mold remover or diluted vinegar.
- Bird Droppings: Clean promptly with diluted dish soap or enzyme cleaner.
- Tree Sap: Use isopropyl alcohol or sap remover sparingly.
- Rust Stains: Apply diluted lemon juice/vinegar mix or CLR (vinyl only).
- Grime/Dirt: Use a baking soda paste.
- Pollen/Insects: Use mild detergent or insect cleaner.
Products and Methods to Avoid
- Magic Eraser: Abrasive; may strip coatings and cause discoloration.
- Armor All: Leaves residue that attracts dirt and degrades coatings.
- Harsh Degreasers/Bleach-Based Cleaners: Can damage fabrics (diluted bleach is acceptable only on vinyl).
- Pressure Washers, Wire Brushes, Undiluted Acids/Alkalis: Cause immediate or long-term damage.
Post-Cleaning Care and Maintenance
- Always dry completely before retracting to prevent mold growth.
- Apply UV protectants sparingly on vinyl or waterproofing sprays on fabric awnings every 6–12 months.
- Use awning covers during off-season storage.
- Inspect every three months for tears, stains, or loose fibers.
- Rinse after each trip and clean thoroughly before and after seasonal storage.
FAQs
Can I pressure wash my awning?
No. High pressure can damage seams and coatings.
Is cleaning worth it if the awning is stained?
Yes, as long as the fabric and seams are intact. Replace only if cracked or delaminated.
Do I need to clean both sides?
Yes, both sides should be cleaned. The underside will pickup dust and dirt which will act like sandpaper during motion, reducing the life of your awning. The cool, shaded underside is appreciated by you as well as insects and spiders. Apply protectant only to the top side.
Can I use bleach?
Only diluted bleach on vinyl; never on acrylic.
What’s the best awning cleaner?
It depends on the fabric. Camco works well for general cleaning, Star Brite for mold and mildew.
How do I remove water spots?
Rinse with vinegar after cleaning.
Conclusion
Proper cleaning and maintenance help extend the lifespan of an RV awning, maintain its appearance, and ensure it functions effectively. By choosing fabric-appropriate cleaners, avoiding damaging products, and applying regular care, an RV awning can remain a durable and reliable feature of any RV setup.
