Depending on who you talk to, many RV enthusiasts recommend washing your rig 10–12 times a year to keep it looking its best. Some RV owners prefer to hire a professional detailer to do the dirty work, but many enjoy the process themselves and get a sense of accomplishment when they’re done. 

If that’s you, here are some must-know RV washing tips to help you clean your RV, camper, or toy hauler safely and effectively.

Use the Right Materials to Protect Your RV’s Finish

Before you start washing your RV, it’s important to use materials and soaps that are safe for your rig’s exterior. Some RVs have a gel coat finish that can scratch easily if you use abrasive brushes or harsh cleaners.

Always check your RV owner’s manual or manufacturer’s website for recommended cleaning products and methods. Using the right RV wash soap and tools will help preserve your RV’s shine.

Invest in a Portable RV Water Softener

One of the best-kept secrets for washing your RV is using soft water. A portable RV water softener, like the PRO+AQUA Portable Water Softener Travel Series helps eliminate minerals like calcium and magnesium that cause water spots.

This system has a 16,000-grain capacity that can provide up to 40 days or 2,000 gallons of softened water, depending on your water hardness and usage. It can also easily be regenerated with the Regen/Pre-Filter Kit.

Using a water softener while washing your RV means you’ll have fewer spots and your soap will work better. Softened water allows soap molecules to create more lather, making the cleaning process more effective and gentler on your RV’s finish.

Choose the Right Pressure Washer for RVs

A good pressure washer is a must-have for any RV owner—it makes washing your rig quicker and easier. However, not all pressure washers are safe for your RV’s exterior.

Pressure washers above 2,000 PSI are too powerful and can cause damage to your paint. Many auto detailers recommend using a washer with 1,500–1,900 PSI. This range is strong enough to address bird droppings, grease, bugs, and tar without damaging your RV’s finish. 

Use the Best Soap for Washing an RV

There are a variety of carwash soaps available in the market. But whatever you do, DO NOT use any type of dish soap. Dish soaps are harsh degreasers that can dull the exterior and strip away wax protection.

Instead, use a quality RV wash soap that’s designed specifically for vehicles. Many of these soaps are available at auto parts stores and big retailers like Walmart. Some RV wash soaps even contain wax, adding an extra layer of protection while you clean.

Upgrade Your Washing Game with a Foam Cannon

A foam cannon  is an excellent tool for washing your RV quickly and thoroughly. It's essentially a bottle that connects to your pressure washer and mixes soap with water to create thick, clinging foam.

The foam covers your RV’s surface, loosening dirt and grime so you can rinse it away easily. Using a foam cannon saves time and ensures an even application of soap, helping you get a spotless, shiny RV every time.

Final Thoughts: Make RV Washing Easier

Washing your RV doesn’t have to be a hassle. By using soft water, the right pressure washer, and quality RV wash soap, you can keep your RV looking like new all year long. Add a foam cannon to your toolkit, and you’ll wonder how you ever washed your RV without it.
