How to wash parts of RV with a pressure washer


RV Roof

Begin on its top and wash the rooftop with a low-pressure type of nozzle. After you reach the RV sides, use a low-pressure sprayer. Aim for a high-pressure stream of water against the edges and metal seams of the RV roof. Focus on these things as they can result in leaks when not adequately protected or sealed.


RV Interior & Windows

Wash the RV interior using a sponge, wet mop, and cloth. Use water combined with a dishwashing liquid. Use a handheld and high-pressure nozzle through those window seals when washing dirt and dust away.


RV Exterior & Sides

Wash the RV with a high-pressure nozzle on the side while you stand in front. Make use of a low-pressure sprayer when cleaning debris and dirt off of the exterior surfaces such as wheels, windows, and more. Once finished with the step, monitor for leaks coming off the pressure washing.


Seals & Gaskets

Wash the windows, exterior doors, seals, and wheel gaskets using a high-pressure type of nozzle. It removes dirt that stays still inside the grooves.


Rims & Wheels

Wash the rims and wheels in the way you wash the RV roof. Use the low-pressure nozzle to wash the dirt away. Use water combined with a dishwashing liquid. It’s up to you spraying it down.


Fiberglass Surface

This fiberglass surface you see is in an older RV as this is in general, unpainted with all those flashy decals. Pressure wash the fiberglass with RV wash alongside wax products designed for it. When you pressure wash it, take the decals away. This force will push them to peel off sooner. For newer fiberglass, it can have a transparent paint coat. It’s ideal to use RV washing chemicals. It’s better to use auto products in this sense.



Three-body types are familiar with an RV. Make use of the pressure washing protocol for any of these. The plain metal body will accumulate dust and dirt. They are somehow the most difficult to clean as they demand a prewash. Include some accessories such as a rotary brush that frees it from dust before washing it. A requirement is more pressure than the average in removing dirt and grime in the metal body.

Follow the same protocols when it comes to a painted metal RV body. Use a foam cannon when spraying soap onto it. Wash it after with low and medium pressure, including a wide-angle nozzle type. The fiberglass body demands gentle handling and light pressure for its lightweight design, bringing in fuel efficiency. The low-pressure foam cannon is essential when pressure washing an RV body.

Mistakes To Avoid As You Wash An RV With A Pressure Washer

Avoid the following errors as you intend to wash an RV with a pressure washer.

  • Never choose the improper wrong pressure setting as for the wash hose. If it’s too low, it’s not possible to generate adequate water flow. The water for pressure washing may only damage the RV protective coating if it’s too high.
  • Never use the wrong size of the nozzle as it’s the top mistake you’ll ever make.
  • Never use a high-pressure type of nozzle as it only washes everything way like the RV protective coating. Or else, it will result in an unprotected surface and corroded metal.
  • Never use soap solution for RV cleaning jobs using a pressure washer. Soap only sticks through the surface after you pressure wash it. It only attracts more dirt afterward. Dishwashing liquid is an even gentler cleaner that washes away debris and dirt.
