Pressure washers for car cleaning and detailing are incredibly useful pieces of equipment. Driving through a brick-and-mortar car wash can cost more money than it should, while an at-home soap-and-bucket car wash could leave you feeling uninspired by your handy work. The best pressure washers use both power and water efficiently, and they tend to offer a good value.

Our review team has combed through dozens of pressure washers for cars in the hopes of helping out customers during their purchasing process. While you may or may not decide on using one of our recommended pressure washers below, all of the products that our team recommends are backed by thorough research and an unbiased review process.

Pressure Washers For Cars Buyers Guide

Pressure washers are commonly used to clean vehicles and for good reason. They work quickly and can be used to easily blow away dirt chunks and road grime. Compared to hand-washing, a pressure washer will save a significant amount of time and energy.

You are not likely to damage your vehicle paint with a pressure washer unless you choose an especially narrow nozzle and set the pressure to the extreme highest setting. Many car detailing enthusiasts prefer to use a pressure washer to start cleaning their vehicle, and to follow up a hose down with hand-wiping for fine detailing.

There are a host of different brands of pressure washers for cars to sort through and there are even more model options to pick from. Having an idea of the type of pressure washer you want and which replaceable nozzle options are included are two things that will make your purchasing process easier.

Types Of Pressure Washers

There are two main types of pressure washers: electric and gas.

  • Electric pressure washers: This type of pressure washer features a push-to-start button and tends to run more quietly and cleanly than its counterpart. Electric pressure washers won’t offer the upper power ranges that some gas-powered models can, but will work well on most light to heavy-duty jobs.
  • Gas pressure washers: This type of pressure washer usually has a manual pull start and provides the power as well as mobility to tackle large jobs. Depending on the model, gas pressure washers can even remove paint.

Nozzle Types

Pressure washers come equipped with an all-in-one variable spray wand that allows you to adjust your water pressure or a set of interchangeable nozzles. Knowing the intended usage of each type of nozzle can give you an idea of which nozzles you’ll need with your pressure washer.

  • 0 degrees: This is the most powerful and concentrated nozzle setting.
  • 15 degrees: This nozzle is meant for heavy-duty cleaning.
  • 25 degrees: This degree of nozzle is intended for general cleaning.
  • 40 degrees: This nozzle is designed for use on vehicles, outdoor furniture, boats, and other easily damaged surfaces.
  • 65 degrees: This degree of nozzle is low-pressure and meant to apply soap and other cleaning agents.

When using a pressure washer to clean your car, the best angle will depend partially on individual preference, but you will likely want to use something between 25 and 40 degrees.
