For about $100 less than our pick, this model cleans comparably, but because it lacks several standout features, it’s much less convenient to use.

An Overview On Car Wash Power Washers

Getting dirt, road salt and grime off your car is not easy. Unless you want to wash it every week and scrub till your arms are tired, you need an easy way to keep your vehicle looking shiny and brand new. A car wash power washer is a handy tool that makes cleaning your car effortless and simple.

There are three main types of power washers. A gas-powered one can quickly and easily clean large areas without any harsh chemicals. It offers a high amount of pressure from a nozzle that has multiple settings. Drawbacks of this kind of pressure washer are that it is incredibly loud while in use and heavy to move.

Electric power washers are ideal for small jobs that are focused on cleaning instead of stain removal. These types of machines are small and relatively quiet, especially compared to their gas-powered counterparts. They are easy to turn on and off and do not need to be winterized. However, electric power washers offer less pressure than gas, which means that they can take longer to do the same job.

There are also battery-powered pressure washers, which use lithium-ion batteries. They don’t offer as much pressure as electric or gas options, but they are ideal for small, lighter cleaning tasks. A bonus is that you can use the batteries in these machines in other power tools like cordless drills if they are from the same manufacturer.

When looking for a car wash power washer, one of the most important things to look at is the nozzle. This is what controls the intensity and angle of the water. If it’s not the right setting for the job, you could be dealing with accidents and injuries. Some power washers come with a set of color-coded nozzles that you can interchange, while others come with one adjustable nozzle that you can configure based on the job at hand.

The Car Wash Power Washer Buying Guide

  • If you’re going for convenience, opt for a car wash power washer that has an adjustable nozzle. It’s easy to change the spray width or intensity with just a few turns. However, if you want a more customized spray based on the kind of cleaning you’re doing, then opt for replaceable nozzles instead. This will give you highly customized spray patterns and angles.
  • You can get injured using a car wash power washer as a result of the spray intensity, so it’s best to read the instruction manual before you get started to ensure you’re using the right settings.
  • While using the power washer, be sure to wear goggles to protect your eyes. You will also want to wear long pants and closed-toed shoes to protect your skin.
  • Don’t start cleaning with a narrow spray angle. It’s safest to start with a wider angle with less intensity. You can narrow the nozzle slightly or move closer to the object if you need to. You should never hold the nozzle closer than 6 inches from the object you’re cleaning. Otherwise you may end up damaging the surface.
  • Always test-wash a portion of your car in a small patch first before you start cleaning all of it. This will help you feel comfortable using the machine and will give you time to work out any kinks.
