How to Wash and Wax Your RV Like a Pro

An RV wash and wax keeps your rig looking good and protected. Weather, debris, and the sun can harm your RV. So keeping it clean and the exterior maintained can help it look good for years. 

We share how to wax your RV in this article. And do you have those pesky black streaks? We give a tip for removing them. Keep reading to learn more, including our product recommendations for what to wash your RV with. 

Let’s get washing.

How To Wash and Wax an RV Like a PRO! New RV Maintenance, Tools, Products and Tips Ep. 14

Should an RV Be Waxed?

Your RV can and should be waxed. It will help protect the exterior fiberglass and paint from UV rays, water, and bug debris and it gives it a shine. Without wax, your RV’s exterior may look faded or keep dirt marks that you could prevent with regular upkeep.

If you have aluminum siding on your RV, stick with waxes for metal surfaces. And if it has fiberglass or another material, use wax for that specific exterior finish. We recommend using a wax specifically designed for RVs. A car wash can work, but we prefer to use a product proven on RVs.

Pro Tip: If you still have clouding, you may need some additional help removing oxidation from an RV’s fiberglass exterior.

How Do You Wash and Wax an RV?

Washing and waxing your RV compares to cleaning a car. But, of course, an RV is much bigger and has some more features on the exterior to pay attention to. 

Before beginning a wash job be sure to inspect all seals around the RV and roof. Washing the RV will increase the likelihood of a leak and making sure it’s sealed up properly before beginning is essential!

Using a brush with an extension for washing your RV helps you get to hard-to-reach places. And you can use it for cleaning the roof, so you don’t have to go on your knees or hurt your back. 

Choose a soap that works for your RV’s exterior finish. Some products have a combination of soap and wax all in one. If you wash and wax separately, read the directions to know how long the RV should dry before waxing.

Depending on the size of your RV, you may want to wash one size or section at a time. And we recommend starting with the front cap and moving back toward the rear. 

For example, if you have a 40-foot motorhome, try washing the front 10 feet of one side first. Then, tackle the next 10 feet and so on. When washing or waxing big rigs, your arms get tired quickly, so take your time and breaks if needed.

What Will Remove Black Streaks From an RV?

Water, rain, or dew running down your RV can cause black streaks. The black comes from dirt that the water takes with it. 

Many people swear by Simple Green All-Purpose Cleaner to remove them. In contrast, some use a mix of hot water, dishwashing detergent, and bleach.

Should I Wax My Fiberglass RV?

You can and should wax fiberglass RVs. Fiberglass has a gloss to it that you need to maintain by waxing. Use RV wax meant for fiberglass, specifically. A brand meant for metal or other materials won’t work as well. 

We recommend following the same regimen you would for washing and waxing any other type of RV. Protecting fiberglass is important and keeping it clean and waxed is part of the process.

Try to wash your RV at least once a month to keep your exterior clean.

How Often Should You Wash and Wax Your RV? 

It’s good practice to wash your RV at least once a season to keep dirt from building up. Dirt can harm the exterior of your RV over time,  and the RV wax protects the paint and keeps it shiny. 

Be sure to wax your RV at least once a year, but you can do it twice or more as you see fit. Try to do so one a sunny and dry day if possible.

Keep Your RV Shiny

A shiny clean RV keeps your tiny home on wheels looking good. And it also keeps your RV in good shape. The sun can eat away at RV exteriors quickly, so the more you can do to keep the surface protected, the better. 

Without wax, UV rays can fade your paint and may create permanent stains where dirt is present. Plus, you can get better resale value by keeping those decals in good shape.

For several years, I use liquid spray wax such as Meguires Quick Wax since it is readable available at Walmart. Spray it on then dry, no buffing. I also use Meguires wash N Wax soap with a foam cannon to apply and scrub with pole scrubber.

I've recently switched to Technicians Choice spray wax with ceramic Tec582 based on RV detailer on Utube. It works great on RV, Camper and Cars. Agin, spray and wipe dry.

Howdy Mortons, I was glad to see you addressed the topic of washing and waxing RVs and look forward to seeing your recommendations for waxes for a fiberglass trailer and then suddenly your article petered out and gave no recommendations. By chance can you amend your article and add some of the products that you have found work we'll on fiberglass trailers? I have tried a couple of products--with mixed success--that are designed for automotive paint, but I am having low trouble locating waxes specifically designed for fiberglass finishes. Thanks, Greg
