How to wash an rv with a pressure washer

Cleaning your RV is a time-consuming and difficult task. It’s not easy to keep the outside of your vehicle looking clean, especially if you live in an area with high humidity or frequent rain storms. A pressure washer can make this job much easier! Follow these simple steps for how to wash an RV with a pressure washer.

What is a pressure washer and how does it work

A pressure washer is a machine that uses pressurized water to remove dirt and grime from surfaces. It achieves this by using an electric motor to drive an axial pump, which forces the water under intense pressure through a nozzle at high velocity. The pressure also helps wash away dirt and grime in small cracks and crevices that are hard to reach. Pressure washers are commonly used by homeowners for washing decks, patios, sidewalks, vehicles, or other outdoor structures

How are they powered?

Pressure washers are typically powered by an electric motor with an axial pump, either powered by AC current or battery power. This means they can be used almost anywhere electricity is available.

Why use a pressure washer to wash an RV

Pressure washing is a popular method of cleaning because the water from the high-pressure nozzle can remove dirt from surfaces easily.

Pressure washers work by changing “the surface tension on the water molecules so they adhere to the dirt and break it loose from its adhered position.” Without a pressure washer, you have to use a lot of elbow grease to clean off larger pieces of dirt. A pressure washer makes it easy to get rid of tough dirt without having to spend a lot of time scrubbing at smudges with a cloth.

Recent studies have shown that people who wash their cars with a pressure washer are less likely to get cancer or heart disease because they spend less time outside in the heat. This is because pressure washers can remove pollen and other allergens from the surface of your car. According to the American Cancer Society, people who spend a lot of time outdoors are more likely to develop skin cancer than those who stay inside.

How to properly setup the power washer for washing an RV, including safety precautions and tips

  • Make sure that your power washer is set at the appropriate pressure. If the pressure is too high, you will end up with water spraying everywhere and it can cause serious injury. A good rule of thumb is to check your instruction manual for your particular power washer to see what the correct pressure should be.
  • Make sure the water source is on a different circuit than your electrical outlets or you will risk shorting out or blowing something out. Typically, this includes turning off the water pump, which is typically where your hose attaches to.
  • After assembling everything, start at one end of the RV and work towards the other side if necessary. The power washer can easily be wheeled around on its own wheels to make this job relatively simple.
  • For an RV, you want to make sure that everything is wet well enough for the cleaner you are using to break down any dirt or grime that may be attached to it. Make sure that the surface of the vehicle is wet in order for it to work properly. You can use a garden hose to wet all surfaces of the vehicle as well as any fixtures, such as door handles and mirrors.
  • If you are using a high-pressure nozzle to clean your RV, then make sure that you keep the surface wet enough for it be effective. This is achieved by using a sweeping motion with the wand instead of a single spot cleaning motion. You can still use the spot cleaning motion with an extremely low pressure nozzle that will not cause damage to the vehicle.
  • Make sure that you are away from any areas where there is traffic before you start cleaning your RV. If necessary, close off the road if it is a smaller road or take down signs if they are necessary.
  • Keep your fingers and body parts away from any openings on the power washer. If you close off the opening, then it will prevent water from coming out and this can decrease or eliminate damage to you and/or someone else who may be in range of the spray.
  • Make sure that you regularly check for broken or cracked hoses and replace them if necessary before you begin your washing process. This can prevent any unnecessary repairs while also preventing a potential injury from the water spray that may come out while you are working on it.
  • You should always keep bystanders away from the area where you will be using the pressure washer for this job, especially children. Injuries can occur without you even knowing it, which is why keeping children away from the area will reduce the chances of an accident.
  • If you are washing your RV in a populated area or somewhere that has people around, make sure that you are not spraying water onto them or near them. The best thing to do in this situation is to notify them of what you will be doing and make sure that everything is OK before you start.
  • After your job is complete, take a moment to clean up any excess water that may be left over from your work as this can reduce the risk of slipping and getting injured. This includes making sure that you do not spray water into areas where it can run into a drain that may not be as obvious as others.
  • To discharge the pressure from the hose, you need to release it from its current position and bring it further away from where you will be working. This prevents any more spraying after your job is complete but will also prevent an accident before it occurs if something were to happen, such as a leak.
  • After you are finished washing your RV, make sure that everything is turned off and put away before you leave the area. This will also reduce any potential accidents or injuries from occurring while you are not there to monitor what is going on with your power washer.
  • If something sounds unusual while you are using the pressure washer, stop what you are doing and check it out to make sure that everything is working properly before you continue. If there is a problem with your power washer, then take a moment to locate any potential replacements or determine if it can be fixed by someone more familiar with this type of equipment.
  • Finally, you should always keep your power washer in good working order by making sure that everything is tightened, cleaned, and oiled if necessary. This will prevent any malfunctions while using it or reduce the time to repair or replace parts that are worn out.
