Washing the exterior of an RV — especially a large one — can seem like a daunting task, but with the proper planning, products and tools, getting a squeaky-clean home on wheels can be accomplished with minimal effort

Like any big investment, an RV needs proper care and maintenance to keep its value and last for years. Regular washing is one of the best ways to keep it looking new and prevent problems that can dampen any vacation. Getting up close and personal to your travel trailer, fifth-wheel, truck camper or motorhome is a good opportunity to do an inspection and make sure items aren’t loose, and that seams, vents and windows are tightly sealed.

Plan Ahead

Before you think about how to wash an RV, think about where you plan to do it. At home, you’ll need a lot of water — a steady supply, not just a few bucketfuls — and a place for it to drain. The surface should be level and solid enough to support your weight on a ladder without tilting or sinking into the ground. Many campgrounds don’t allow RV washing with water, so you may need a waterless cleaner. If there’s a shady spot available, grab it. Most cleaners work better on cool surfaces than on sun-warmed ones.

Rather than spreading out cleaning products, brushes and sponges all over the ground or taking multiple trips back and forth to the garage, consider a product like Grit Guard’s Universal Detailing Cart. The 40-inch-high-by-24-inch-wide-by-18-inch-long rolling work station is outfitted with three shelves to keep everything needed at your side. A top-shelf cutout is designed to hold a bucket or the company’s Universal Pad Washer, and the cart’s edges are rounded to keep it from damaging the RV should it accidentally bump into it. The durable thermoplastic cart has multidirectional casters for easy maneuvering.

Next, lay out the cleaning tools. The ones you’d use to wash a tow vehicle will probably do, such as a large bucket, a soft wash mitt, sponges, and several brushes with hard and soft bristles. You’ll also need a long or extendable handle for the brushes so you can reach high up on the sides and across the roof. A car-wash-type brush with a long handle that you can attach to a garden hose for a constant supply of clean water works well. Don’t forget a sturdy ladder, and wear shoes with nonslip soles — there’ll be a lot of soapy, slippery water around.

Use the right cleaner for the particular RV’s surface; if in doubt, check the owner’s manual for recommendations. Painted and coated aluminum finishes can scratch easily. Always check the manufacturer’s instructions for cleaning because the wrong cleaner can damage or strip off decals, and even damage the clear-coating on aluminum trailers like Airstreams. Painted metal can be cleaned using the same products and tools for washing a car. For fiberglass, use a washing product that leaves a coating of wax behind.

Use a lot of water to sluice off the loose dirt and grit, and then go over it again with
a soft-bristled brush or a wash mitt and a nonabrasive cleaner. Unless you’re a pro with a pressure washer, don’t use one. High-pressure water can blow right past gaskets, silicone seals and the overlap of sliding windows. It can also peel decals off with frightening efficiency. Don’t use more pressure than a garden hose with a sprayer can generate, and let a brush do the job of freeing up the dirt.

Take It from the Top

Now it’s time to get down to the nitty-gritty. It should go without saying, but it needs to be said anyway: Begin by closing all doors, windows and rooftop vents. Now head for the roof. Besides getting the hard part out of the way early on, a top-down wash means the runoff from the roof won’t stream down the walls you just cleaned. But it will loosen and sluice away some of the dirt on the sides, front and back before you tackle them.

Cleaning and examining the roof is also an important process for ensuring the seals are in good condition. Membrane roofs are the most common in use today, and there are special cleaners and treatment products for these. Don’t use anything with petroleum distillates or citrus oil. Fiberglass and aluminum roofs can be washed the same way as the side walls.

Walking around on top of a wet, soapy RV isn’t the surest path to a long and healthy life, and the roof might not even be designed to bear your weight. Here’s where a stable ladder and a long brush extender pay their way. Climb up and reach across the roof with a brush on a pole, spray water around, loosen the dirt, then rinse well. Apply cleaner and do it all again, scrubbing harder this time. Finally, rinse off the roof with plenty of water.

If there are seals and gaskets that need attention, wait until the roof is absolutely dry before making repairs. If you have a walk-on roof with a ladder built on the RV, carefully walk on the trusses if possible (you’ll feel them), or lay a wide board or two down to distribute your weight across the trusses, front to back, if it makes you feel more comfortable.

All Sides Now

The sides, front and back of the RV can be washed using the brush on a pole. Wet down the surfaces, remove the loose dirt, then rinse. Using the appropriate cleaners and brushes, soap up, brush down and rinse off the sides. With smaller rigs — or taller RVers — you may be able to use a soft wash mitt, but be sure to rinse the loose dirt out of it often. Otherwise, you’re just rubbing dirt, and possibly abrasive sand, onto the surface.
This also means that it’s smart to change the water in the bucket frequently to prevent sediment from getting into the mitt or brush and damaging the side walls. Consider a Grit Guard bucket or insert to keep grit out of the soap solution.

Canopy Cleaning

To clean a vinyl awning, use a good awning fabric cleaner and your extendable brush. Heavy stains can usually be removed using a slightly stronger cleaner like Spray Nine or Simple Green. Mildew can be cleaned using a bleach solution. Plan on getting wet when cleaning underneath.

Acrylic and other fabric awnings can dry quickly due to air circulation through the fabric. Sometimes a solution of mild dish detergent and water is all you’ll need, but be sure that the awning is completely dry before retracting it to the stowed position. Spot stains can be cleaned with K2r.

Ponte Vedra Beach, Florida-based Awesome Products’ Love Bug Eraser simplifies cleanup after a lovebug-filled drive.Close Encounters of the Bug Kind

During the spring and summer months, lovebugs swarm the highways and byways in the southeastern United States and the Gulf Coast, just waiting to hurl themselves at RVs and other vehicles. Left to bake in the sun, their acidic body fluids can damage paint, plastic and fiberglass. Ponte Vedra Beach, Florida-based Awesome Products’ Love Bug Eraser simplifies cleanup after a lovebug-filled drive.

The secret to the Love Bug Eraser is the patented fibers that give it the ability to wipe off bugs, dirt, bird droppings, grime and road tar when using it in conjunction with car-wash soap and water. The 9½-by-6-inch pad is reusable and safe for use on metal, chrome, glass, plastic, paint and graphics, according to the company. Since no chemicals are involved, it’s safe for use around children. If no hose is available, the product can be used effectively with a spray bottle of water. When done, just rinse out, dry, and it’s ready for its next use.

Love Bug pads are sold individually, in multiples or as part of a kit, and the company also offers an RV Roof Cleaning Kit. Coming soon is a wheel-and-tire-cleaning kit.

Don’t forget to clean the insides of the windows along with the outsides. While you’re cleaning the windows, be sure to examine the rubber seals and gaskets for drying, cracking or tears, and clean and treat them with the appropriate conditioner. Exercise all the windows and emergency exits as well.

Wheels and Tires

RV wheels — whether painted, polished or chrome — can be cleaned the same way as those on the tow vehicle, using the same basic products and techniques. This is also an
opportunity to inspect the tires for cracks, splits and punctures, in addition to wear.

Don’t use any cleaners or protectants on the tires that contain petroleum distillates or ammonia. Tire manufacturers almost universally recommend nothing more than a mild detergent. Shiny black tires might look good, but some products that give the tires that look play havoc with chemicals in the rubber compound designed to protect it from ozone exposure and premature sidewall deterioration.

Undercarriage

The dirtiest part of any vehicle is the undercarriage, and it is often the most forgotten. Dirt allowed to collect on these surfaces can lead to rust and decay of the frame and other components.

The frame is steel, and will put up with any cleaner or water spray thrown at it. However, slideout seals, underbelly materials and such are not, and using too much water spray in the wrong way can cause water damage to the RV. The Spray Nine and Simple Green type of cleaners, your extension brush and a hose with a sprayer are most likely adequate for cleaning these areas. If the frame is particularly filthy, careful use of a pressure washer is OK, but stick to the frame unless you’re a pro and really know what you’re doing. Once dried, touch up the frame with a good quality rust-stop spray paint.

Final Analysis

It’s much easier to spot potential problems on a clean RV than a dirty one, so take the opportunity of a good wash to examine the exterior for damage, rust spots, wear points and anything else that might turn into a bigger problem later. Check outside storage bins and the inside of entry doors and windows for signs of moisture where it shouldn’t be. Small leaks can cause big damage if left unchecked.
