Mobile RV Washing: Everything You Need to Know

Mobile RV washing means a professional detailing crew comes to wherever your RV is parked and washes it on-site, without you hauling it to a shop. It's the most practical option for full-timers, people with large Class A motorhomes, and anyone whose rig is stored at a campground or storage facility. You get a clean RV without moving it, and a good crew can handle everything from a basic exterior rinse to a full wash, wax, and roof treatment.

In this guide I'll cover what mobile RV washing actually includes, how much you should expect to pay, what questions to ask before you book, and how to keep your RV clean between professional visits.

What Mobile RV Washing Actually Includes

The term "mobile RV washing" covers a wide range of services, and companies don't all define them the same way. Here's what you'll typically find at each tier.

Basic Exterior Wash

At the entry level, you're getting a hand wash of the sidewalls, front cap, and rear. The crew uses a wash mitt or soft brush and a dedicated RV soap like Meguiar's #67 RV Cleaner or Chemical Guys CWS_101 Wash and Gloss. They rinse, dry with microfiber towels, and move on. This takes about 45 minutes to an hour on a 30-foot Class C.

No wax, no wheel cleaning, no roof. Just clean paint. This runs $75 to $150 depending on rig length.

Full Detail Package

Full detail usually adds:

Roof wash (the most important part, since oxidation and black streaks start there)
Wheel and tire cleaning and dressing
Window treatment with Rain-X or a similar product
Bug and tar removal from the front cap
A liquid wax or sealant application

On a 40-foot Class A diesel pusher, a full detail will take two to three hours with two people and costs $250 to $500. Some high-end operators include a one-step polish if they notice light oxidation.

Deep Restoration Detail

If your RV has been sitting in the sun for years, the gel coat or painted fiberglass is probably oxidized to a chalky, dull finish. A restoration detail includes compound polishing with a machine polisher like the Flex PXE 80 or Rupes LHR15 Mark III, followed by a protective coating or wax. This is a full day of work and costs $600 to $1,500+ for a large motorhome.

How to Find a Reputable Mobile RV Washer

Google Maps is your starting point. Search "mobile RV washing [your city]" or "RV detailing near me." What to look at:

Reviews that mention specific rigs. If someone says "they washed our 38-foot Tiffin Allegro Bus," that tells you more than a generic five-star review.

Before and after photos. Any detailer worth hiring has photos. If they have none, that's a red flag.

Insurance. Ask whether they carry general liability insurance. An uninsured detailer who scratches your $200,000 motorhome is a serious problem.

Rig size experience. Class A motorhomes, 5th wheels, and travel trailers need different equipment. A detailer who works only on sedans and SUVs may not have a tall enough ladder or the right brushes for a 13-foot-tall coach.

RV-specific Facebook groups and forums like iRV2.com are also great sources. Ask for recommendations in your area and you'll get firsthand referrals quickly.

Pricing Breakdown by RV Type

Pricing follows length and complexity, not just time. Here's a realistic range for mobile services:

RV Type	Basic Wash	Full Detail
Travel trailer (20-24 ft)	$60-$100	$150-$250
Class C motorhome (25-32 ft)	$100-$175	$225-$375
Class A gas (33-38 ft)	$150-$225	$300-$500
Class A diesel (38-45 ft)	$200-$300	$400-$650
5th wheel (30-40 ft)	$125-$200	$275-$450

These are national averages. Prices run higher in California, Florida, and the Pacific Northwest where labor costs are elevated.

What Water Source Does the Detailer Use?

This is a question most RV owners forget to ask. Mobile RV washers handle their water supply in one of three ways:

Self-contained tanks. The best mobile operators bring their own water in a skid tank on their truck or trailer. They fill it from a municipal source and bring enough for the job. No hookup needed at your location.

Your campground water hookup. If you're at a campground, most will allow a detailer to use your site's water connection. Just ask the campground office first; some charge a small fee.

Water-fed pole systems with purified water. High-end RV washing outfits use deionized water delivered through a carbon-fiber pole, similar to window cleaning rigs. Purified water leaves no mineral spots, so they can skip the hand-drying step. It's faster and gentler on the finish.

If you're at a storage facility with no water access, make sure to confirm your detailer is self-contained before booking.

Equipment That Separates Good Detailers from Mediocre Ones

You can tell a lot about a mobile RV washer by the equipment they show up with.

Pressure washers. A good RV detailer uses a pressure washer in the 1,500 to 2,000 PSI range with a wide fan tip (40-degree nozzle) to rinse. High pressure (3,000+ PSI) can force water into seals and damage decals. Check out our guide to the best pressure washers for mobile detailing if you're curious what the pros use.

Soft-bristle brushes. The exterior of your RV is fiberglass or aluminum skin, not metal. Stiff brushes leave scratches. Pros use a boar's hair brush or soft nylon blend for scrubbing.

Telescoping ladders and poles. Reaching the roof of a Class A requires a 10-12 foot ladder or an extension pole system. If someone shows up without a way to reach the roof, walk away.

Microfiber towels in bulk. Professional detailers bring stacks of clean 16x16 or 400 GSM microfiber towels for drying. Old cotton rags or bath towels drag across the surface and leave swirl marks.

How Often Should You Wash Your RV?

The standard recommendation from fiberglass manufacturers is every three months for a wash and once a year for a wax or sealant. That said, your storage situation matters more than a calendar.

If you store your RV outdoors under trees, wash it every six to eight weeks. Bird droppings and tree sap are acidic and etch into gel coat quickly. If it lives under a covered carport or RV storage building, you can stretch washes to four to five months.

The roof needs special attention. Black streaks on RV sidewalls come from dirt and algae washing off the roof. If you treat and clean the roof twice a year, those streaks stop forming. Dicor Roof Cleaner and Protector works well on EPDM rubber roofs, while Geocel ProFlex works for TPO.

Tips for Maintaining Your RV Between Professional Washes

You don't need to deep clean between professional visits, but a few habits will keep things looking sharp.

Rinse after rain. Rain picks up airborne pollutants and deposits them as water spots when it dries. A quick rinse with a hose within 24 hours after rain prevents those spots from baking on.

Spot-treat black streaks immediately. Products like Bio-Kleen M00509 Black Streak Remover dissolve streaks without harming decals or fiberglass. If you catch them fresh, it takes about five minutes. If they sit for months, they require real scrubbing.

Keep slide room seals conditioned. This isn't a washing task, but it's connected. Dicor Lap Sealant applied to slide room seals annually prevents the leaks that cause water staining on the lower sidewalls.

FAQ

Do I need to be home when the mobile RV washer comes?

For exterior-only washes at a storage facility, no. You can arrange key card access or leave the storage unit unlocked. For interior cleaning or any work that requires accessing your rig, you or someone you trust should be there.

Can a mobile RV wash damage my decals?

Yes, if done wrong. High-pressure nozzles aimed at decal edges will peel them. A good detailer uses low pressure and stays several inches away from decal borders. If your decals are already lifting at the edges, let the detailer know before they start.

Should I tip a mobile RV detailer?

There's no industry standard, but 10 to 15% is common for quality work. On a $300 job, that's $30 to $45. Many mobile operators are owner-operators, so tips go directly to the person doing the work.

How long does a mobile RV wash take?

A basic wash on a 30-foot Class C takes 45 to 90 minutes for one person. A full detail on a 40-foot Class A with two technicians runs three to four hours. Restoration polishing on a heavily oxidized rig is a full day job.

The Bottom Line

Mobile RV washing is worth the money for the convenience alone, but you get the most value when you book a crew that knows large coaches, carries their own water, and uses proper equipment. Schedule exterior washes every three months and a full detail with wax once a year. Treat black streaks with a spot cleaner between visits and rinse after heavy rain, and your rig will hold its appearance and resale value for years.
