RV detailing is the most under-served corner of the mobile car wash industry. Most car detailers can’t physically handle a 38-foot Class A — they don’t have the ladders, the long-reach extension tools, or the chemistry. The result is a generation of motorhome owners who run their RVs to the carwash bay once a year and watch the fiberglass slowly turn chalky.
This guide explains why RVs need different treatment, the roof work that virtually every owner skips, and how mobile service makes the math actually work.
Why RV detailing is different
The vertical surfaces are huge
A Class A motorhome has 250–400 square feet of paint surface. A Class C with full body paint can hit 300 sq ft. That’s 4–5x a full-size SUV. Detailing time and labor scale proportionally — a full polish on a 36-foot RV is a 12–16 hour job done correctly.
The roof is the most-neglected surface
Almost nobody looks at their RV roof. It’s 30+ feet up, painted with rubber EPDM or TPO on Class C / Class A, and has solar panels, vents, AC shrouds, and seams that all need attention. UV destroys roof membrane faster than any other surface — and a $40 annual conditioning treatment can extend its life by 5+ years.
Oxidation moves fast
RV gelcoat and fiberglass panels oxidize 2–3x faster than automotive paint because they’re larger flat surfaces with no aerodynamics breaking up direct sun exposure. A neglected RV develops "chalky" exterior within 24–36 months of new.
Awnings, slides, and seals
Side awnings collect mold and mildew. Slide-out seals dry-rot from sun exposure. Both need targeted maintenance most car detailers don’t carry products for.
What a proper RV detail covers
Roof cleaning and treatment
Soft-brush wash with EPDM- or TPO-safe cleaner (depending on roof material), seam inspection, and conditioner application. Critical: we never use citrus or petroleum-based products on rubber roofs — they degrade the membrane chemically.
Exterior wash
Two-stage wash: pre-soak with foam, then hand-wash with extended-reach soft brush (an actual telescoping tool, not a household brush). Bug front and grill get a separate dedicated bug remover. Roof-edge transitions where dirt streaks collect get extra attention.
Oxidation removal and polish
For chalky fiberglass: compound, polish, then wax or sealant. For full-body paint Class A: paint correction is similar to luxury auto but on a larger scale. Plan a full day for a 38-foot Class A.
Awning cleaning
Awning fabric gets brushed with awning-specific cleaner, rinsed thoroughly, and dried before retracting. Mold streaks need a separate treatment and sometimes don’t fully come out — but they can be stopped from spreading.
Slide-out maintenance
Seals get cleaned and conditioned with rubber conditioner (303 Aerospace or equivalent). Slide topper fabric gets washed. Mechanisms get inspected (we report, not service — that’s an RV tech’s job).
Interior detail
Same playbook as a luxury car but bigger: vacuum, steam clean carpets, leather conditioning on furniture, kitchen and bathroom deep clean, windows and screens, vent cleaning.
How often to detail an RV
- After every trip: Hand-rinse to remove road grime, bugs, and tar. Within 24 hours of returning.
- Quarterly: Full exterior wash, roof inspection, awning rinse.
- Every 6 months: Roof treatment (EPDM/TPO conditioner), seal conditioning, polish/sealant top-up.
- Annually: Full polish + interior deep clean + slide-out service.
Stored RVs that don’t move for 6+ months still need the roof and seals serviced. UV doesn’t care if you’re driving.
Where most owners get it wrong
Pressure washing roofs
Never pressure-wash an EPDM rubber roof. The seal around vents, AC units, and the perimeter is held by lap sealant — pressure spray lifts the sealant and water gets into the roof deck. This is the single most common preventable RV repair we see.
Using automotive cleaners on awnings
Automotive soaps strip the awning fabric’s waterproof coating. Use awning-specific cleaner only.
Buying chalky resealer products without compounding
Spray-on "RV restoration" products covered up the problem briefly but bake the oxidation into the surface. Proper compound + polish is the only real restoration.
Ignoring the rear cap
The rear of the RV gets the worst UV exposure when parked nose-in. It’s the panel that fades first and the one most overlooked in DIY washes.
Mobile vs RV park wash bay
Most RV parks have wash bays but they’re a $20 high-pressure spray that does almost no actual work. They’re useful for rinsing road dust between trips, not for actual detailing. The labor an RV needs — roof treatment, polish, awning, slide-out conditioning — only happens with a mobile pro showing up to your storage spot or campground.
Service areas and access
We service RVs at:
- Self-storage facilities across LA and OC (most allow detailing on site with check-in)
- Residential driveways (verify HOA rules on commercial vehicles before booking)
- RV-friendly campgrounds and parks within the LA / OC service radius
- Selected dealerships and RV consignment lots
Class A motorhomes over 40 feet require a confirmed flat parking area with safe ladder access. Send dimensions and a photo when booking.
What it costs
Rough pricing for mobile RV detailing in Southern California:
- Exterior wash + roof rinse (32-ft Class C): $250–$400
- Polish + roof treatment + awning clean (36-ft Class A): $800–$1,400
- Full restoration: oxidation removal, polish, ceramic sealant (38-ft Class A): $2,500–$4,500
- Interior deep clean (added to any package): $300–$600
Book mobile RV service
RV detailing requests come through the custom request flow rather than the standard package booking — we need vehicle length, location, and access details before quoting. Most owners get a quote within a business day, often after a Rabbit visits the site briefly.
