Best Pressure Washer for Vehicle Cleaning

Simpson PS3228 3300 PSI 2.5 GPM Gas Pressure Washer ($529)

best pressure washerBefore we get into the merits of the Simpson PS3228 Gas Pressure Washer, let’s make one thing abundantly clear: you should never use a pressure washer to actually clean your vehicle.

With that caveat out of the way, the Simpson PS3228 is an excellent model for fast, smooth application of soap and thorough rinsing, which can save hours of time and tons of elbow grease if you operate a car dealership or maintain a commercial vehicle fleet. The ergonomic spray gun provides a perfect blend of comfort and control, with five stainless steel nozzle tips and a plastic soap nozzle to handle other household and light commercial applications as well as car, truck, boat and RV detailing.

  • Weight: 83 pounds
  • Wheel size: 10 inches

Our pick in this category, the Karcher 15-inch pressure washer surface cleaner attachment, features two spinning nozzles to deliver a streak-free, 15-inch cleaning area for driveways, decks, patios, garage doors and home siding.

Pressure Washer Buying Guide and Frequently Asked Questions

What’s the Difference Between a Pressure Washer and a Power Washer?

The primary difference between pressure washers and power washers is the inclusion of a heating element in the latter. Otherwise, they frequently have similar PSI and GSM ratings.

The heat component of a power washer makes them somewhat more effective in removing grease and oil stains, but they also cost more and require more maintenance. Paired with a good detergent, pressure washers can achieve virtually the same results as power washers for a significantly lower cost. 

What’s the Difference Between PSI and GPM?

Both PSI (pounds per square inch) and GPM (gallons per minute) ratings provide a picture of a pressure washer’s maximum power. PSI reflects the force behind the water as it meets the surface you’re cleaning; higher pressure means faster, more effective cleaning, but it can also damage delicate surfaces, so make sure the PSI level you’re using is appropriate for the task at hand. Pressure can be adjusted by using differently-sized tips, with a 0° tip providing the most concentrated force and higher-angle tips delivering more dispersed pressure. 

GPM (gallons per minute) measures the maximum rate of water flow that a pressure washer can achieve. Increased water flow can remove dirt, debris or other material more quickly from a surface, while reducing the flow with a flow control valve can deliver gentler cleaning or rinsing, which is especially important for washing vehicles or other easily-marred surfaces. 

To calculate the total power of any given pressure washer model, simply multiply the PSI and GPM measurements together. For example, a model with a 3200 PSI, 2.5 GPM rating offers a total power of 8,000, while a model with 4000 PSI and 2.1 GPM barely edges it out with a total power rating of 8,400. 

How Much Pressure Washer Power Do You Need?

When considering how much power you’ll actually need from your pressure washer, take a look at the following list of common tasks and the optimal PSI for each one. When in doubt, purchase the washer with a higher power rating; you can always reduce the force by changing the nozzle, but there’s not much you can do to add muscle to a low-power machine.

500 PSI or less:

  • Wicker patio furniture 
  • Screens
  • Vehicles

500 to 2000 PSI:

  • Grills
  • Other patio and lawn furniture
  • Light mildew and mold
  • Light stains on concrete or asphalt
  • Shutters

2000 to 3000 PSI:

  • Concrete driveways, sidewalks and patios
  • Decks
  • Fences
  • Siding
  • Mildew, mold and other stains
  • Use with small surface cleaner attachments

3000 to 4000 PSI:

  • Asphalt
  • Decks
  • Fences
  • Graffiti removal 
  • Heavily stained concrete driveways, sidewalks and patios
  • Masonry and tile 
  • Mold and mildew
  • Paint prep
  • Graffiti removal 
  • Use with large surface cleaner attachments

4000 or greater PSI:

  • Concrete 
  • Graffiti removal
  • Concrete 
  • Paint stripping

What’s the Best Power Source for a Pressure Washer?

Pressure washers are available in electric-, gas- and battery-powered models, and each option has distinct benefits and weaknesses. 

Many homeowners opt for electric-powered pressure washers due to their low maintenance requirements, reduced carbon footprint and quiet operation. However, electric pressure washers produce notably less power than similar gas-powered models, which means the same cleaning job will take additional time to complete. If you decide to go the electric route with your purchase, be sure to look for a model with GFCI protection. 

Gas pressure washers easily deliver the most powerful pressure and water flow, but they can also be disruptively loud. Gas engines also produce significant emissions and fumes and require frequent maintenance. 

Battery-powered options are somewhat limited, in large part because the market for these comparatively weak units is small. However, if you anticipate using your washer for light-duty tasks and value portability over power, you may wish to consider one of these models. They tend to be extremely lightweight and easy to transport but also have reduced run time based on the strength of the lithium ion batteries they rely on to function. 

Do I Need a Residential or Commercial Model?

Though some consumer models claim to deliver professional-grade power, these washers are still unlikely to be able to meet the demands of true commercial or industrial applications. The main differences between residential and commercial machines can be identified in the engine and the pump. 

Commercial pressure washers feature commercial-grade engines like Honda’s GX series, while residential washers use smaller, less rugged engines such as the Honda GC series. As far as the pump goes, commercial washers often rely on industrial triplex pumps, while residential models usually incorporate axial cam pumps or integrated designs. 

Unless you’ll be using the pressure washer in a commercial cleaning, painting or industrial setting, a washer designed for residential use should provide plenty of power for any cleaning task you need to tackle. 

What Pressure Washer Accessories Do I Need?

Most pressure washer packages include several key accessories, including a hose, a wand and several nozzles. Depending on your needs, you may wish to upgrade the items provided with accessories that offer advanced capabilities or higher quality. 

Pressure Washer Accessories: Nozzles

Most pressure washers use ¼-inch quick-connect nozzles, making them easy to swap out for various tasks. Standard options include 0°, 15°, 25°, 40° and soap, although your specific model may not include all of them. Nozzles are relatively inexpensive, allowing you to replace broken or poorly-performing models or add wider or narrower nozzles to your collection. Keep in mind that nozzles have a PSI rating that will need to be compatible with the machine you are using, so be sure the nozzles you purchase have a high enough rating to work with your washer. 

Pressure Washer Accessories: Hoses

Like nozzles, hoses are rated for a set PSI and are typically matched by the manufacturer with the machine you purchase. If you decide to replace the original hose due to length or some other factor, try to match the PSI rating of the old one as closely as possible. Using a hose with a PSI rating that’s too low could damage the hose or your washer, while a hose with an excessively high PSI rating can negatively impact the performance of your unit, especially if you select a hose with a larger diameter. 

Pressure Washer Accessories: Wands

Due to their necessarily hollow, lightweight design, pressure washer wands are the component most prone to breakage and other damage. To extend the life of your wand as much as possible, try to keep it hanging off the ground when not in use and avoid leaning it against walls, vehicles or other objects. 

When you do end up investing in a new wand, look for a model with a PSI rating, diameter and threading to match your pressure washer and spray gun. If you frequently find yourself cleaning high or hard-to-reach surfaces, a telescoping wand (which may extend up to 24 feet) may be a smart investment.
