How to Clean RV Awnings

To clean RV awnings, follow a simple process. Extend the awning fully, remove loose dirt with a soft brush, prepare a mild soap and water solution, apply it with a soft brush or sponge, then retract and let it soak for 5 to 30 minutes. Extend again and rinse thoroughly using a garden hose. Allow the fabric to dry completely before retracting, and repeat the process if necessary. An RV awning is a retractable fabric cover mounted to the side of a recreational vehicle. It provides shade, shelter from rain, and helps reduce interior heat by blocking sunlight from windows and doors. The best way to clean an RV awning includes regular maintenance using a gentle awning cleaner and avoiding harsh chemicals that damage the fabric or waterproof coating.

An RV awning needs cleaning when dirt, tree sap, bird droppings, or mildew become visible or after exposure to damp environments.  Dust, leaves, insect residue, and mold caused by moisture are common contaminants. Regular cleaning prevents buildup that leads to stains, odors, or fabric breakdown. Maintaining a clean awning extends its lifespan, raises its appearance, and ensures proper function. Routine care preserves resale value and creates a pleasant shaded area during outdoor activities. RV awning cleaner and protectant are products for deep cleaning and long-term fabric protection. The technique is similar to how to clean camper awning and helps keep the awning in excellent condition during travel seasons.

1. Extend the awning fully

Extending the awning fully involves rolling it out to its maximum length to reveal the entire fabric surface, on top and underneath. The action is necessary for cleaning, as it exposes all areas where dirt, stains, mold, and mildew tend to collect. Full extension allows access to hidden sections that stay covered when the awning is rolled up. Inspection becomes easier when the entire awning is visible, helping identify worn areas or damage. The RV must remain parked on a stable surface to ensure safe extension. Clearance around the RV must be confirmed before beginning. Power awnings require the control panel, while manual models follow specific manufacturer instructions. Spotters help monitor the process for obstructions and ensure an even rollout. The awning arms must be secured and locked after full extension to maintain tension and prevent damage. Full extension ensures better cleaning coverage and helps preserve the awning fabric, reduce long-term wear, and maintain proper function.

2. Remove loose dirt and debris with a soft brush

Removing loose dirt and debris with a soft brush involves gently sweeping the surface using a soft-bristled brush or broom to clear away dust, leaves, and other loose particles. A soft brush with a long handle or extension is recommended for complete coverage without putting pressure on the awning material. Sweeping the top and underside, when accessible, helps avoid dirt buildup in hidden areas. Clean in sections using light, controlled motions to prevent damaging the fabric. Avoid using wire brushes or stiff bristles, which tear the awning or strip protective coatings. Performing the process on a dry, fully extended awning improves results and prevents smearing.

The initial cleaning stage prevents surface debris from turning into mud or causing abrasions during wet cleaning. It allows cleaning agents to penetrate the fabric more efficiently by removing obstructions. Regularly brushing off debris in dusty areas or under trees, helps avoid mold growth, staining, and fabric deterioration. The technique protects water-repellent coatings on acrylic awnings, contributing to longer material life. Brushing with slight agitation lifts particles lodged in grooves or weaves on textured surfaces. No cleaning solution is required when removing loose dirt and debris, making it a quick yet impactful step in maintaining the awning’s appearance and durability.

3. Prepare a mild soap and water cleaning solution

Preparing a mild soap and water cleaning solution is a crucial first step in maintaining RV awnings. The solution is made by mixing 1/4 cup of biodegradable liquid dish soap with one gallon of warm water in a bucket. It gently lifts dirt, pollen, and stains without damaging vinyl or acrylic fabrics. The soap works as a surfactant, breaking the bond between grime and fabric, while water rinses away loosened debris. Applying the mixture with a soft-bristle brush or sponge using circular motions ensures effective yet gentle cleaning. Letting the solution sit for five minutes on tough stains improves results by allowing deeper penetration.

Avoid harsh chemicals, abrasive tools, and cleaning in direct sunlight, which leads to residue buildup. Use RV-specific awning cleaners or gentle household alternatives like vinegar and baking soda for persistent stains. The step protects the awning’s structure and coating, extends its lifespan, and improves the outdoor experience. Routine cleaning with the solution reduces the risk of mold, damage, and costly repairs, making it an essential part of RV maintenance.

4. Apply the solution with a soft brush or sponge

Applying a cleaning solution with a soft brush or sponge helps loosen and lift embedded dirt, mold, mildew, and other contaminants that are difficult to remove with water alone. The soft bristles or sponge fibers reach into the textured surface of the awning fabric without causing damage. A proper cleaning solution, such as a mix of mild dish soap and water or a commercial RV awning cleaner, improves the process by effectively breaking down grime. Fully extending the awning provides access to both sides, ensuring complete coverage during cleaning.

Correct application involves dipping the brush or sponge into the cleaning solution and scrubbing the fabric with gentle, circular motions. Focus must be given to stained areas without applying excessive pressure. Best practices include using a soft brush for vinyl and a stiffer brush for acrylic, avoiding bleach or harsh chemicals, and cleaning the awning regularly. The step preserves fabric strength, prevents stains, and extends the overall life and functionality of the awning.

5. Retract the awning and let it soak for 5–30 minutes

Retracting the awning and allowing it to soak for 5–30 minutes increases the effectiveness of RV awning maintenance. Retracting the extended awning traps the cleaning solution between the fabric layers after applying it on both sides. The soaking period moistens the awning, allowing the solution to penetrate deeply and loosen dirt, sap, mildew, and other debris. The process treats persistent stains or mold that regular surface cleaning does not entirely remove. Letting the awning soak ensures even distribution of the cleaner, helping to break down the buildup that accumulates over time.

Properly executing the step requires selecting an appropriate cleaning solution, which includes mild dish soap, a commercial awning cleaner, or a diluted vinegar solution for mold spots. Apply the solution with a brush, mop, or sprayer, then roll up the awning gently, avoiding overly tight rolling to ensure complete contact. Allow it to soak for 5 to 30 minutes based on the severity of the stains, ensuring the fabric stays damp but not dry. Regular use of the method prevents long-term damage, extends the fabric’s lifespan, and helps maintain a clean, mildew-free surface.

6. Extend and rinse thoroughly with a garden hose

Extending and rinsing thoroughly with a garden hose means opening the RV awning completely and using a garden hose to remove dirt, debris, and leftover cleaning solution. Complete extension reveals all surfaces, making it possible to clean the top and underside of the fabric. A gentle spray setting on the hose avoids fabric damage while washing off loose particles effectively. Starting from the top and moving downward ensures proper flow of water and soap removal. Clean awning surfaces help preserve the material’s water-repellent qualities and prevent long-term staining.

Soft-bristle brushes and mild, bleach-free cleaners are recommended for the washing step before rinsing. Repeating the rinsing process helps lift embedded grime without harsh scrubbing. Gentle tools protect the fabric’s coating and structure while ensuring thorough cleaning. Proper rinsing keeps chemical residue from breaking down the fabric. The step extends the lifespan of the awning by maintaining its integrity, appearance, and resistance to environmental wear.

7. Allow the awning to dry completely before retracting

Allowing an RV awning to dry completely before retracting helps preserve the awning’s condition. Moisture left on the fabric becomes trapped once the awning is rolled up, creating an enclosed environment where mold and mildew thrive. Mold leads to fabric deterioration, foul odors, and stubborn stains. Damp conditions cause rust on the awning’s arms, springs, and other metal components. Fabric dry rot occurs over time if moisture remains, reducing the awning’s lifespan and effectiveness. The drying step protects the fabric and mechanical parts from damage and extends overall durability.

Proper drying begins by extending the awning in a sunny, breezy area. Sunlight and fresh air speed up moisture evaporation across the entire surface. Humid or cloudy weather requires extra drying time, sometimes lasting several days. Folds and creases must be checked, since they tend to trap moisture longer. A thorough rinse with clean water removes any remaining residue. Excess water is shaken off gently before the fabric is left to air dry. Early retraction due to sudden rain must be followed by reopening and drying the awning as soon as possible.

8. Repeat cleaning if necessary

Repeat cleaning if necessary to address any remaining dirt, mold, or mildew that persists after the initial wash. A visual inspection of both sides of the awning must follow the first cleaning. A second cleaning round becomes essential if stains or grime are still visible. A fresh solution, such as 1/4 cup of dish soap mixed with five gallons of water, must be applied directly to affected areas using a soft or medium-bristle brush. Scrubbing gently with circular motions helps loosen tough buildup without damaging the fabric. An effective method of removing mold and mildew from the underside of the window is to use a Magic Eraser sponge. Allowing the cleaning solution to sit by rolling up the awning for several minutes improves penetration, making it easier to remove embedded debris.

Repeating the cleaning process ensures a more thorough result for neglected or heavily soiled awnings. Stubborn stains, tree sap, or mildew require more than one attempt for complete removal. Proper rinsing with clean water after each cycle eliminates soap residue and prevents future buildup. Spot treatments are more efficient than re-cleaning the entire awning. Repeating the step helps preserve the material, extending its lifespan and avoiding damage that leads to expensive replacements. Regular and complete cleaning prevents odors and mold-related health concerns, while keeping the awning visually appealing and ready for use.
