Keeping your RV clean isn’t just about looking good on the road—it’s essential for preserving the vehicle’s finish, preventing long-term damage, and maintaining its value. Whether you’re prepping for a big trip or giving your rig some post-adventure TLC, here’s how to properly clean the exterior of your RV.
Why Cleaning Your RV Matters
Before diving into the process, it’s worth understanding why regular cleaning is a must:
-
Protects Paint and Decals: Dirt, bugs, bird droppings, and sap can erode paint and damage decals.
-
Prevents Oxidation: Regular washing prevents the buildup of grime that can lead to surface oxidation.
-
Spot Damage Early: Cleaning gives you the chance to inspect seals, seams, and accessories for cracks or leaks.
-
Improves Fuel Efficiency: A clean RV creates less drag than a dirty one, helping with mileage.
What You’ll Need
-
Long-handled soft-bristle brush or mop
-
Ladder (if needed for roof access)
-
RV-safe soap (non-abrasive and biodegradable)
-
Bucket and hose with spray nozzle
-
Microfiber cloths or towels
-
Wax or UV protectant (optional but recommended)
-
Bug remover (for stubborn residue)
-
Wheel and tire cleaner
Tip: Avoid household cleaners, as they may strip wax or damage seals.
Step-by-Step RV Cleaning Guide
1. Start with the Roof
Begin at the top so dirty water runs down the sides as you work. Use a ladder safely and avoid walking directly on the roof unless it’s rated for foot traffic.
-
Rinse the roof thoroughly.
-
Scrub using RV roof cleaner appropriate for your material (rubber, fiberglass, etc.).
-
Rinse again and inspect seals and vents while you’re up there.
2. Rinse the Entire Exterior
Give your RV a full rinse to remove loose debris and soften dried-on dirt.
-
Use a hose with a spray nozzle to reduce water use.
-
Avoid pressure washers unless your RV manufacturer approves them.
3. Wash Section by Section
Work from top to bottom, so you don’t re-soil clean areas.
-
Use a soft brush or sponge with RV-safe soap.
-
Rinse each section before the soap dries to avoid streaking.
4. Tackle Bugs and Tar
Use a designated bug and tar remover for the front cap, mirrors, and lower sides.
-
Let the product sit as directed before gently scrubbing.
-
Avoid scrubbing too hard—especially on decals.
5. Clean the Wheels
Use a separate brush for your tires and rims.
-
Apply wheel cleaner and scrub thoroughly.
-
Don’t forget the wheel wells.
6. Dry the RV
Water spots can ruin a clean finish, especially in direct sunlight.
-
Use microfiber cloths to dry the surface.
-
Work quickly to avoid spotting.
7. Apply Wax or Protectant (Optional)
Protect your RV’s finish and make future washes easier.
-
Use RV-specific wax or UV protectant.
-
Apply according to product instructions—some are spray-on, others require buffing.
Bonus Tips
-
Wash in the Shade: Direct sunlight can cause soap and water to dry too quickly, leaving streaks.
-
Use Deionized Water (if possible): Helps prevent water spots.
-
Schedule Routine Cleanings: A quick rinse every couple of weeks and a deep clean every few months is ideal.
Final Thoughts
Cleaning the exterior of your RV is more than just a cosmetic task—it’s a crucial part of responsible RV ownership. With the right tools and techniques, you’ll not only keep your rig looking sharp but also extend its life for many adventures to come.
