10 Common RV Cleaning Mistakes to Avoid
Cleaning an RV might seem simple — soap, water, and a towel, right? But one wrong move can lead to scratches, oxidation, or damage to seals and graphics. Whether you’re a first-time RV owner or a seasoned traveler, these are the most common RV cleaning mistakes to avoid — and what to do instead for a spotless, protected finish every time.

1. Using the Wrong Soap
One of the biggest mistakes RV owners make is using household dish soap or cheap car wash products. These strip away wax, dry out seals, and accelerate oxidation. Instead, use a purpose-made soap like The Super Soaper — designed to lift grime while preserving coatings and paint protection.
Wash Your RV the Safe Way
The Super Soaper is formulated for RVs and large vehicles — high foam, strong cleaning, and gentle on coatings.

Jumping straight to contact washing without pre-soaking can grind dirt into the paint, causing micro-scratches. Always foam or pre-soak your RV first to soften grime before touching the surface.
3. Using Rough or Dirty Towels
Dirty or low-quality towels can do serious damage. Always use dedicated, clean microfiber towels — ideally the Orange Wash Microfiber Towels from Jimbo’s Detailing. These ultra-soft, high-pile towels safely lift dirt and grime without scratching delicate paint or gel coat.
Use the Right Towels for the Job
Orange Wash Microfiber Towels are designed to safely wash large RV surfaces without leaving swirls or scratches.

Washing your RV under the hot sun leads to soap drying on the surface, leaving water spots and streaks. Try to wash in the morning, late afternoon, or in shaded areas. If you must wash in sunlight, work in small sections and rinse frequently.
5. Ignoring the Roof
Many RV owners forget to clean their roof, allowing dirt and mold to drip down over time, creating black streaks on the sides. Wash the roof first using The Super Soaper and a soft brush, then rinse thoroughly down the sides.
6. Neglecting Trim and Rubber Seals
Plastic trim and rubber seals can dry out and crack when neglected. Apply All Dressed Up every few months to keep them supple, UV-protected, and looking new.
7. Using High-Pressure Washers Improperly
A pressure washer can be a great tool — if used safely. Too much pressure or the wrong angle can lift decals and damage seals. Keep pressure under 1,500 PSI and maintain a safe distance of at least 3 feet from the surface.
8. Forgetting to Clean the Undercarriage
The underside of your RV takes a beating from salt, grime, and road debris. Neglecting this area can lead to rust and corrosion. Use Pure Magic Cleaner and an undercarriage sprayer to flush and protect this vulnerable area.
9. Not Drying Properly
Air drying may sound easy, but it leaves behind water spots and minerals that dull your finish. Use the Massive Drying Towel to safely wick away water and leave a spotless surface.
10. Skipping Protection After Washing
Washing removes contaminants — but also weakens existing protection. Always follow up with a coating or spray sealant like Tough As Shell Ceramic Spray. It creates a slick, UV-resistant layer that keeps your RV cleaner longer.
