Keeping your RV’s finish looking shiny and fresh isn’t rocket science, but it does take a little know-how and the right supplies. Road trips, random weather, dust, bugs, and tree sap can all leave your RV looking beat up over time. Regular cleaning not only makes your home on wheels look good, but it also protects the finish, keeps the resale value high, and helps you spot minor problems before they turn into major fixes.
Choosing the Right Cleaning Products for Your RV
Your RV’s surface isn’t usually the same as your daily driver. It could be fiberglass, gel coat, aluminum, painted metal, or a mix. Each surface has its own needs, so picking the right soap is really important. That store-bought car wash soap often works perfectly for newer RVs, especially those with a clear coat finish. It removes dirt without stripping protective waxes or making your finish look dull.
For older rigs or those with faded sides, RV-specific washes are the way to go. These are gentle on coatings, strong enough to wash away grime, and less likely to cause problems over time. Avoid using dish soap or household cleaners; they might strip off wax, speed up oxidation, or dull the shine. Popular brands like Thetford, Camco, and Meguiar’s make washes just for RVs. Looking for something easier on the environment? There’s options that are biodegradable too.
Some areas such as the roof or the bug-splattered front cap may need a specialty cleaner. Make sure to pick products marked safe for RV rubber or TPO roofs, and only use bug or tar removers that are made for gel coat or paint. If in doubt, read the label and go for gentle solutions to preserve your RV’s looks.
Supplies You Need for Washing Your RV
You don’t need a commercial garage full of tools, but the right basics make the job easier and help protect your finish:
- SoftBristle Brush on a Telescoping Handle: This helps you reach those high spots without risking a shaky ladder climb.
- Gentle Microfiber Wash Mitts and Towels: They grab onto dirt, rinse clean easily, and won’t scratch your finish.
- Buckets: Use a two-bucket system–one for soapy water, one for rinsing. This reduces the risk of grinding in grit.
- Garden Hose with Adjustable Nozzle: A pressure washer can be handy, but keep it on a low setting and use a wide spray for safety.
- Dedicated Roof Cleaner and Brush: Keeping the roof clean prevents grime from washing down onto freshly cleaned sides.
- Wheel and Tire Brush: Great for getting into metal seams and scrubbing off brake dust and stubborn road gunk.
A few extras like a step stool, detailing brushes for tight spots, and rubber gloves can really smooth the way.
Understanding Your RV’s Finish
Not all RVs are made from the same materials. Here’s a summary to help you look after your specific setup:
- Gel Coat (fiberglass): Looks glossy and slick when new. With age, it can get chalky. Use gentle soap, a soft brush, and add some polish from time to time.
- Painted Metal Siding: Common on many travel trailers and Class C RVs. Treat it similarly to your car’s paint, using mild cleaners and gentle tools.
- Aluminum: Especially on older models and Airstreams. Harsh chemicals can pit or stain aluminum easily, so stick with mild, metal-safe cleaners.
- Vinyl Decals: Only use cleaners marked as safe for decals. Always test any new product in a hidden spot first.
- Rubber or TPO Roofs: Go with cleaners made for RV rubber roofs. Avoid petroleum products, which can cause long-term damage to your roof membrane.
If you’re not sure about your RV’s finish, check the owner’s manual or ask your dealer before getting started. Knowing your surface goes a long way in keeping it looking sharp and avoiding costly repairs from harsh chemicals.
Step by Step Guide to Washing Your RV
Washing an RV can take a little longer than your car, but it’s worth the time. Here’s a routine that’s worked for me and plenty of fellow travelers:
- Pick a shaded area: This keeps the soap from drying too fast and helps prevent stubborn water spots.
- Rinse from top to bottom: Always start with the roof. Letting the dirt come down saves you from having to rewash the sides.
- Wash the roof: Use a dedicated roof cleaner for rubber or TPO tops, and gently scrub with a softbristle brush.
- Move down to the walls: Use your mitt or brush dipped in soapy water. Work on one section at a time and rinse before it dries.
- Tackle stubborn spots: Bugs and road tar need RVsafe removers. Spot treat where needed; avoid any product with abrasives.
- Clean windows and trim: Use a glass cleaner or vinegar and water mixture for windows. Wipe trim and chrome gently with a soft towel.
- Wheels come last: Since there’s plenty of brake dust and dirt here, save them for last to avoid splashing the cleaned sides.
- Dry it all off: Microfiber towels help prevent water spots and leave your RV with a streakfree finish.
Taking your time and working in sections makes each step more manageable. Plus, you’ll get a really good look at your rig and can catch anything that might need fixing down the road.
Things to Avoid When Washing Your RV
Some mistakes can be expensive or tough to undo. Here’s what I make sure to stay away from:
- Shooting pressure washers at seams and windows: High-pressure water pointed at seams or vents can force moisture behind panels, leading to leaks or mold.
- Using abrasive sponges and brushes: Even slight abrasiveness can leave scratches or swirl marks, especially on decals.
- Dish soap: It strips wax and can actually speed up fading.
- Letting soap dry on the surface: Dried soap is hard to remove and leaves visible spots.
- Washing in direct sunlight: Hot surfaces dry soap too fast and almost always streak the finish.
- Generic tire cleaners on RV rubber roofs: Many aren’t compatible and can wreck roof membranes surprisingly quickly.
Always err on the side of caution when picking cleaning tools and products for your RV. A little extra care goes a long way to keeping things in top shape.
Extra Shine: Using Wax, Sealant, or Polish
Once your RV is clean, an RV wax or sealant adds a layer of shine, protects your paint or gel coat, and makes washing easier next time. Here’s what to keep in mind:
- Liquid Spray Waxes: Quick and easy to apply. Super convenient for travel and safe for newer RVs, but not the longest lasting.
- Paste Waxes: These give more protection and a richer shine, but require more time and elbow grease. They’re perfect if you’re after a nextlevel cool look.
- Polish or Restorer products: These can help bring back shine to faded gel coats before you wax—especially useful for older RVs. Be patient; results come with a little hard work.
Always double-check that your product won’t hurt the material or any decals. Testing on a small area beforehand saves a lot of trouble. Finish with a thorough hand buff for the ultimate shine.
Maintaining Shine Between Full Washes
Keeping your RV looking good is much easier when you handle regular, quick touchups between washes. Using a microfiber duster on dusty days, rinsing bugs off soon after a drive, or wiping up water spots after rain all make a big impact. RV quick sprays and detailers are great for this and help with stubborn spots. If you park under trees or at campsites with lots of sap, pine needles, or pollen, portable covers can help protect your finish from the elements.
Taking time for these quick jobs means the big cleanings don’t feel like chores, and your RV will always turn heads when you hit the road.
Additional Tips for Long-Term RV Surface Care
Protecting your RV’s exterior is about more than just a wash and wax. Here are key pointers for the long run:
- Inspect seals and caulking regularly: During washes, check all seams—those spots are where leaks sneak in. Touch up any trouble spots with an appropriate sealant promptly.
- Store under cover if possible: Whether it’s a carport, RV-specific storage, or even a high-quality cover, limit sun exposure to prevent fading and chalky discoloration.
- Keep gutters and roof drains clear: Clogged drains let dirty water streak down the sides and can cause mold or stains.
- Use tire covers: Sun cracking ruins tires quickly, leading to an eyesore or even a safety risk. Tire covers are cheap insurance for looks and longevity.
- Wash road salt off soon after trips: If you’ve been driving in areas where winter roads are salted, wash your undercarriage and body promptly to avoid rust or corrosion.
- Perform seasonal deep cleaning: At least once or twice a year, schedule a thorough cleaning, including the roof, awnings, and all compartments. Doing a deep dive helps you spot potential trouble areas early.
A little regular attention will pay off big when it comes to surviving tough weather, keeping up appearances, and maintaining that pricy investment.
