Gather the Right Cleaning Supplies Before You Start

Having the right supplies makes all the difference between a quick, effective cleaning and a frustrating afternoon of scrubbing. After cleaning hundreds of awnings over the years, I’ve learned that preparation prevents problems.

Essential Cleaning Products for RV Awnings

You’ll need a gentle RV-specific awning cleaner like 303 Fabric Cleaner or Simple Green Pro HD for most situations. Avoid household cleaners with bleach or harsh chemicals that can damage vinyl or fabric.

Keep a bottle of mildew remover like Star Brite Mildew Stain Remover for stubborn spots. For vinyl awnings, add a UV protectant like 303 Aerospace Protectant to prevent cracking and fading after cleaning.

Tools and Equipment You’ll Need

A telescoping pole with soft-bristled brush attachment saves your back and reaches high spots safely. Pack a spray bottle for applying cleaners and a garden hose with adjustable nozzle for rinsing.

You’ll also need microfiber cloths for detailed work and a sturdy step ladder for areas the pole can’t reach. Don’t forget a plastic tarp to protect your RV’s exterior from cleaning runoff.

Safety Gear and Protective Items

Wear safety glasses to protect your eyes from cleaning solution splashes and debris falling from the awning. Non-slip shoes are essential when working on wet surfaces around your RV.

Disposable gloves protect your hands from harsh cleaners and prevent skin irritation. Keep a first aid kit nearby since working overhead with cleaning solutions always carries some risk of accidents.

Remove Debris and Loose Dirt First

Before applying any cleaning products to your RV awning, you’ll need to clear away surface debris and loose dirt. This preliminary step prevents scratching during the washing process and ensures your cleaning solutions work more effectively.

Sweep Away Leaves and Large Particles

Use a soft-bristled broom or brush to gently sweep away leaves, twigs, and other debris from the awning fabric. Work from the center toward the edges to avoid pushing materials into the awning’s crevices. Don’t forget to clear debris from the awning’s support arms and roller tube area, as these spots often collect pine needles and small branches that can cause damage if left unattended.

Rinse with Low-Pressure Water

Spray the entire awning surface with low-pressure water from your garden hose, starting at the top and working downward. Keep the water pressure gentle to avoid forcing dirt deeper into the fabric weave or damaging the awning material. This initial rinse removes loose dirt and dust while preparing the surface for deeper cleaning with specialized RV awning cleaners.

Check for Stuck-On Materials

Inspect the awning carefully for bird droppings, tree sap, or other stubborn materials that won’t come off with water alone. Gently scrape off any hardened deposits using a plastic scraper or your fingernail, being careful not to tear the fabric. Mark these problem areas mentally so you can give them extra attention during the cleaning process with appropriate spot treatments.

Choose the Appropriate Cleaning Solution

Selecting the right cleaner makes the difference between maintaining your awning and accidentally damaging it. Different cleaning solutions work better for specific types of dirt and awning materials.

Mild Soap Solutions for Regular Cleaning

Mix one cup of mild dish soap with five gallons of warm water for basic maintenance cleaning. This gentle solution effectively removes everyday dirt and grime without harming your awning fabric. Dawn or similar grease-cutting dish soaps work exceptionally well for removing food spills and general camping residue. Apply with a soft brush and rinse thoroughly to prevent soap buildup.

Specialized RV Awning Cleaners

Commercial RV cleaners like Star Brite Awning Cleaner or Camco Pro-Strength remove stubborn stains more effectively than soap alone. These products contain enzymes specifically designed to break down mildew, tree sap, and UV-caused discoloration. Follow manufacturer dilution ratios precisely – typically one part cleaner to ten parts water. These specialized formulas work faster and require less scrubbing effort.

Avoid Harsh Chemicals and Bleach

Never use bleach, ammonia, or petroleum-based cleaners on your RV awning fabric. These chemicals break down the protective coatings and waterproof treatments, leading to premature fabric failure. Avoid pressure washer detergents containing degreasers or acidic compounds. Stick to pH-neutral cleaners to preserve your awning’s longevity and maintain its weather-resistant properties.

Use Proper Washing Techniques

Proper washing technique makes the difference between a clean awning and potential damage that’ll cost you hundreds in repairs. Following the right sequence and methods protects your investment while achieving better results.

Work from Top to Bottom

Start at the highest point of your awning and work systematically downward. This prevents dirty water from dripping onto areas you’ve already cleaned, eliminating the need to re-wash sections.

Use overlapping strokes as you move down each section. Gravity naturally pulls dirt and cleaning solution downward, so you’re working with physics rather than against it.

Keep your cleaning pattern consistent across the entire awning surface. This ensures even coverage and prevents streaking that can occur when you randomly jump between sections.

Apply Gentle Scrubbing Motions

Use circular motions with light pressure when scrubbing your awning fabric. Heavy scrubbing can damage the protective coating and weaken the material’s UV resistance over time.

Let your cleaning solution do most of the work by allowing it to sit for 2-3 minutes before scrubbing. This breaks down stubborn dirt and reduces the physical effort needed to clean effectively.

Choose soft-bristled brushes or microfiber cloths over abrasive materials. Hard brushes can create micro-tears in the fabric that become entry points for water and dirt in the future.

Focus on Problem Areas and Stains

Identify heavily soiled areas before you start the general cleaning process. These spots typically include the front edge where road grime accumulates and areas under tree branches.

Apply extra cleaning solution to stubborn stains and let it penetrate for 5-10 minutes. Mildew spots and bird droppings require this extended dwell time to break down completely.

Work problem areas with a dedicated brush or cloth that you won’t use on cleaner sections. This prevents spreading contaminants across your entire awning during the cleaning process.

Rinse Thoroughly and Remove All Soap Residue

Your RV awning’s longevity depends heavily on eliminating every trace of cleaning solution after washing. Soap residue attracts dirt faster and can break down the fabric’s protective coating over time.

Multiple Rinse Cycles for Complete Cleaning

Start with a thorough first rinse using clean water from top to bottom, working systematically across the entire awning surface. You’ll need at least two complete rinse cycles to ensure all cleaning solution is removed from the fabric.

Give special attention to areas where you applied extra cleaning solution for stubborn stains. These spots require additional rinsing time to prevent soap buildup that can cause premature fabric deterioration.

Check for Soap Buildup in Creases

Focus on fabric creases and fold lines where soap naturally accumulates during the washing process. These areas often retain cleaning solution even after your initial rinse cycles.

Use your spray nozzle to direct water specifically into these creases and seams. Run your hand along the fabric edges to feel for any slippery residue that indicates remaining soap buildup.

Ensure No Chemical Residue Remains

Test random sections of your awning by running clean water over them and watching how it beads or flows. Water should flow evenly without creating sudsy patches or leaving streaky marks behind.

Pay particular attention to areas where you used specialized cleaners or mildew removers. These concentrated solutions require extra rinse time to prevent chemical damage to your awning’s protective UV coating.

Allow Complete Drying Before Retracting

Never rush the drying process after washing your RV awning. Moisture trapped in a retracted awning creates the perfect environment for mold and mildew growth, which can permanently damage your awning fabric.

Extend Awning Fully for Air Circulation

Pull your awning out to its maximum extension to maximize airflow across both surfaces. This position allows wind to reach every section of the fabric and prevents moisture from collecting in the folds. Even a slight breeze will dramatically reduce drying time when your awning is fully extended, compared to partially retracted positions that trap humid air.

Check Both Sides for Moisture

Walk around your RV to inspect both the top and bottom surfaces of your awning fabric. The underside often retains moisture longer than the exposed top surface, especially in areas where water pools or drips collect. Press a dry cloth against suspicious spots to test for dampness, paying special attention to seams and corners where water typically accumulates.

Wait for Optimal Weather Conditions

Choose sunny, breezy days for awning washing whenever possible to speed up the drying process naturally. Avoid washing your awning before rain or in high humidity conditions that can extend drying time for hours. If you must wash during less-than-ideal weather, consider using fans or allowing extra time before retracting to prevent moisture-related damage.

Perform Regular Maintenance Inspections

You’ll catch problems early when you make inspection a habit rather than waiting for obvious damage. The best time to inspect is during your regular cleaning routine when you can examine every inch of the awning fabric and hardware.

Look for Signs of Wear and Damage

Examine the fabric surface for small tears, thinning areas, or color fading that indicate UV degradation. Run your hands along the awning edges where stress points develop first. Check for loose stitching in the hem and reinforcement areas.

Look for water stains or discoloration that might signal developing mold issues. Pay attention to areas where the fabric stretches over the roller mechanism, as these spots experience the most wear.

Check Hardware and Mounting Points

Inspect all mounting brackets, screws, and support arms for looseness or corrosion. Wiggle each support arm to feel for play in the joints. Test the extend/retract mechanism by operating it slowly while listening for unusual sounds.

Examine the roller tube for dents or bent sections that could cause uneven rolling. Check the tension adjustment mechanisms and spring assemblies for proper operation and visible wear.

Plan Seasonal Deep Cleaning Schedule

Schedule deep cleaning sessions at the beginning and end of each camping season to address accumulated damage. Mark your calendar for pre-storage cleaning in fall and pre-season inspection in spring when you can assess winter damage.

Plan monthly light cleanings during active use periods, especially after camping in dusty or pollen-heavy environments. Consider professional inspection every 2-3 years if you’re a full-time RVer putting heavy use on your awning system.

Conclusion

Taking care of your RV awning doesn’t have to be overwhelming when you follow these proven practices. Regular cleaning and maintenance will keep your awning looking great while preventing expensive damage from mold mildew and UV exposure.

Remember that consistency is key – establish a routine that works for your camping schedule and stick with it. Whether you’re dealing with light dust or stubborn stains the right approach and materials will always deliver better results than rushing through the process.

Your awning is a significant investment that enhances your outdoor experience. By implementing these best practices you’ll enjoy years of reliable shade and protection while maintaining your RV’s overall value and appearance.
