What You’ll Need to Wash Your RV
Before you begin, gather these supplies and set up a safe work area. Like a chef who chops and preps ingredients before cooking, collecting the equipment and cleaners you need in advance will help you achieve a thorough, scratch-free clean.
Must-Have Cleaning Tools
Gather these tools and supplies before you begin washing your RV exterior:
A soft-bristle or telescoping wash brush
A microfiber mitt or sponge
A gentle hose nozzle with adjustable settings
A sturdy ladder for reaching the roof
Two buckets for washing and rinsing
A large microfiber towel or squeegee for drying
If your RV includes a retractable or slide-out awning, this is a great time to give it some attention, too. For more detailed care steps, see our full guide on how to clean RV awnings.
Best Cleaners for RV Exteriors
Select a cleaner made specifically for RVs or maintaining marine finishes. These products should lift dirt and grime without damaging the protective coatings on your vehicle. Avoid dish soaps and other household detergents that can dry out and strip wax.
Safety Tips & Gear to Use While Cleaning
Wear gloves and non-slip shoes to prevent falls and protect your hands. Avoid standing on wet surfaces, and always make sure your ladder is secure before climbing.
Step-by-Step Guide to Cleaning Your RV Exterior
Follow this process for a pro-level clean that will protect your vehicle and get it looking fresh.
Step 1: Prepare the Area & Park on Level Ground
Choose a shaded area and park on a flat surface. Close windows and doors tightly, and ensure all vents and compartments are sealed.
Step 2 Start With the Roof
Begin with the roof so debris and soap can rinse down the sides. Clean the top using a soft brush and an RV-safe cleaner. If you have aslide-out awning, clean and rinse it while you’re on the roof to prevent buildup. Be sure to use a cleaner that is appropriate for your awning fabric and thoroughly dry the awning before retracting. This will prevent mold and mildew from discoloring and damaging your awning.
Step 3: Rinse From Top to Bottom
Use a gentle, steady stream of water to remove loose dirt. Rinsing before scrubbing helps prevent scratches and swirl marks.
Step 4: Wash the Exterior in Small Sections
Work from the top down and focus on one panel at a time. Apply soap with a microfiber mitt or brush, then rinse before moving to the next section. This prevents water spots and get you a shiny, even finish.
Step 5: Clean Windows, Wheels, and Tires
Previously used sponges can collect dirt and debris that can scratch your windows and covers. Use a separate mitt or sponge for these areas to avoid unintended scuffing. Clean wheels last to avoid spreading brake dust or grease onto painted surfaces and glass.
Step 6: Adjust for Different RV Materials
Fiberglass, aluminum, and painted surfaces may need different products. Always follow manufacturer recommendations to maintain the finish.
Step 7: Dry Thoroughly to Prevent Water Spots
Dry with a soft towel or microfiber cloth to protect your paint and reduce streaking. For a flawless finish, use a clean, dry towel to gently wipe down windows and trim.
Waxing & Surface Protection After Washing
Once your RV is clean, protect the finish with a coat of wax or sealant. Waxing creates a smooth surface that resists dirt, UV rays, and water stains.
How Often Should You Wax an RV?
Most RVs benefit from waxing two to four times per year, depending on use frequency and storage location.
Best RV Waxes for Different Exterior Finishes
Fiberglass or Gel Coat: Use a high-quality RV or marine-grade wax.
Painted Aluminum: Synthetic waxes or polymer sealants offer lasting protection.
Matte Finishes: Use specialized matte protectants instead of traditional wax.
Always consult your vehicle manual or manufacturer before selecting a wax.
UV Protection and Finish Longevity Tips
Waxing regularly helps prevent fading and oxidation. For additional UV protection, considerSunblocker and Sideblocker accessories that reduce sun exposure while adding privacy and shade to your campsite.
How to Clean Your RV Awning Without Damaging It
Keep the awning on the frame. There is no need to remove the fabric to clean it. Do not use any oil-based cleaners or caustic, granulated or abrasive cleaners on your awning or any Carefree product. Use a mild soap and a soft brush for vinyl fabric or a stiff brush for acrylic fabric. Rinse thoroughly and let your awning dry completely before retracting. If you notice damage or wear while cleaning, it might be time to replace or upgrade your awning. Explore our complete collection ofprecision-engineered awnings for every RV.
Common Mistakes to Avoid When Washing an RV
When washing an RV exterior, even experienced owners can make errors that dull their finish or damage seals. Keep these tips in mind for the best results.
Avoid Using High-Pressure Washers
Excess pressure can force water behind seals and decals. Use a standard hose or low-pressure setting instead.
Don’t Use Abrasive Brushes or Harsh Cleaners
Scrubbing with the wrong tools can cause scratches and remove protective coatings. Stick with soft, non-abrasive tools.
Avoid Washing in Direct Sunlight
Washing in full sun can cause soap to dry quickly and leave streaks or spots. Aim for shade or cooler morning hours.
Never Skip Rinsing or Drying
Always rinse off all soap and dry thoroughly. Standing water can leave mineral deposits and damage surfaces over time.
Maintenance Between Washes
Consistent upkeep keeps your RV looking great and makes every wash easier.
Quick Clean-Up Tips After a Trip
After each trip, rinse away bugs and road grime with a damp cloth or mild cleaner. A quick rinse can prevent buildup and protect your paint.
