Mobile RV Wash and Detailing: What It Is, What It Costs, and How to Find the Right Service
Mobile RV wash and detailing brings professional cleaning and restoration service directly to wherever your RV is parked, whether that's your driveway, a storage facility, an RV park, or a campground. It's a specialized service because RVs are dramatically larger than passenger vehicles, require different products and techniques, and present unique challenges like roof cleaning, awning restoration, and oxidized fiberglass or aluminum siding.
If you're searching for this service, you likely already know that getting a 30-foot Class A motorhome into a standard car wash or detail shop isn't practical. Here's everything you need to know about mobile RV wash and detailing, from what's included to what it costs and how to find a qualified provider.
What Mobile RV Detailing Actually Covers
Mobile RV detailing is not the same as a standard car wash scaled up. RVs have exterior surfaces, systems, and materials that require specific products and methods.
Exterior Wash and Rinse
The exterior wash is the starting point. A professional mobile RV detailer uses a low-pressure rinse system or a soft-bristle brush to clean the sides, front cap, and rear. Pressure washers are used carefully on RVs because excessive pressure can force water into seams and window seals, leading to leaks and water damage inside.
Most detailers use a dedicated RV wash soap like Gel-Gloss RV Wash and Wax or Nu-Foam RV Cleaner, which are formulated for fiberglass and aluminum surfaces. Dish soap and standard car wash soap can strip the protective finish on fiberglass.
Roof Cleaning
This is where most owners run into trouble doing it themselves. The roof of an RV collects black streaks, mold, mildew, and oxidation from constant UV exposure and moisture. A mobile detailer climbs up and scrubs the roof with products like Dicor Corporation Rubber Roof Cleaner (for EPDM rubber roofs) or a fiberglass roof cleaner.
Roof cleaning should include the caulked seams around vents, antennas, and AC units, which are common entry points for water if allowed to crack and peel. A thorough detailer will note any sealant areas that need attention, though actual sealant application is usually a separate service.
Black Streak Removal
Those dark vertical streaks running down the sides of almost every RV are caused by runoff from the roof carrying road grime, rubber, and oxidation down the exterior. Products like Bio-Kleen Black Streak Remover or Thetford Premium RV Cleaner are designed specifically to dissolve these without damaging the siding. This is usually a separate step from the basic wash.
Oxidation Removal and Polish
Fiberglass and gel coat oxidize over time, turning chalky, dull, and gray. A thorough mobile detail includes machine polishing with compounds like 3M Finesse-It or Meguiar's RV One Step Cleaner Wax to remove oxidation and restore the original shine. Heavily oxidized surfaces may require multiple passes with an aggressive compound before finishing with a lighter polish.
This work is time-intensive. A 40-foot Class A with significant oxidation can take a full day of polishing alone.
Wax or Sealant Application
After polishing, a protective wax or paint sealant is applied to the exterior surfaces. Products like Protect All Fiberglass Polish and Restorer or Chemical Guys Butter Wet Wax are popular choices. Carnauba wax is traditional and gives a warm shine. Synthetic sealants last longer (3 to 6 months vs. 4 to 8 weeks for wax) but require more preparation to bond correctly.

Interior Cleaning
Many mobile RV detailers also offer interior cleaning. This covers the living area: kitchen surfaces, bathroom, bedroom, and the cab area. RV interiors have unique materials including fabric walls, vinyl flooring, and curved surfaces that require softer cleaning tools and milder products.
Interior deep cleaning for an RV typically runs 4 to 6 hours on its own for a full-size unit.
What Does Mobile RV Wash and Detailing Cost?
RV detailing pricing is based on length, roof type, surface condition, and service level. It's consistently more expensive than car detailing due to the size and time involved.
| Service | 20 to 25 ft | 30 to 35 ft | 40+ ft |
|---|---|---|---|
| Basic exterior wash | $100 to $175 | $150 to $250 | $200 to $350 |
| Exterior wash + black streak removal | $175 to $300 | $250 to $400 | $350 to $500 |
| Full exterior detail (wash + polish + wax) | $400 to $700 | $600 to $1,000 | $800 to $1,500 |
| Interior cleaning | $150 to $300 | $200 to $400 | $300 to $500 |
| Full interior + exterior | $500 to $1,000 | $800 to $1,400 | $1,100 to $2,000 |
Heavily oxidized surfaces typically add 20 to 40 percent to the exterior detailing cost because of the additional compound and polishing time.

How to Find a Qualified Mobile RV Detailer
Not every mobile car detailer has the equipment or experience to work on RVs. You want someone who specifically markets RV work.
Search strategies: - "Mobile RV detailing near me" on Google (more specific than "car detailing") - RV park bulletin boards, both physical and online communities - RV forums and Facebook groups (these are excellent for local recommendations) - RVshare and Outdoorsy's community boards often have service recommendations by region - Yelp filters by "RV" in the automotive category
When you contact a detailer, ask:
- What products do you use on fiberglass vs. Aluminum siding?
- How do you approach the roof, and what's your process for rubber vs. Fiberglass roofs?
- Do you carry your own water supply?
- Are you insured for RV work specifically?
- Can you share before-and-after photos of RV jobs?
A detailer who can answer these questions specifically and correctly has done RV work before. Vague answers indicate they're treating it like a large car.
How Often Should You Have Your RV Professionally Detailed?
Most RV owners do a full exterior detail once or twice a year, with basic washes more frequently (every 4 to 8 weeks when in use). The key factor is oxidation prevention. Once fiberglass oxidizes severely, it requires significantly more work and product to restore than if you maintained it annually.
Black streak removal should happen whenever you notice streaking, which in wet climates can be every few months. Roof resealing isn't strictly part of detailing but should be done at the same time since the detailer is already up there.
After a season of storage, especially in sun or humid conditions, is a particularly good time to schedule a full detail. UV exposure and condensation from temperature swings cause the most cumulative damage.
FAQ
Can I wash my RV with a standard car wash soap? Car wash soaps designed for automotive paint can be used on RV fiberglass in a pinch, but they're not ideal. RV-specific soaps like Gel-Gloss or Meguiar's RV One Step are formulated for the materials and are less likely to strip the protective finish. Avoid dish soap entirely on any RV exterior.
Is it safe to pressure wash an RV? Yes, with care. Keep pressure below 1,200 PSI on the sides and avoid directing the spray at seams, window edges, and roof joints, which can force water past the sealant. Soft-brush wash systems are gentler on fiberglass and gel coat than pressure washing.
How do I remove oxidation from my RV between professional details? Light oxidation responds to a compound like Meguiar's M49 Mirror Glaze or Turtle Wax ICE Compound applied with a dual-action polisher or by hand with a foam applicator. Follow with a wax or sealant to protect the restored surface. Heavy oxidation is best handled by a professional with commercial-grade compounds and a rotary polisher.
How long does a full mobile RV detail take? A basic exterior wash takes 2 to 4 hours depending on size. A full exterior detail with oxidation removal and waxing takes 6 to 10 hours for a 35-foot motorhome. Some providers do this over two days for larger units or heavily oxidized surfaces.
Key Takeaways
Mobile RV wash and detailing is a specialized service that goes well beyond what a standard car detailer offers. Look for a provider with specific RV experience, proper products for your roof and siding material, and their own water supply. Schedule a basic wash every 4 to 8 weeks when the RV is in use, and a full exterior detail at least once a year to prevent oxidation from getting ahead of you. A well-maintained RV exterior holds its value and saves you from expensive restoration work down the road.
