A power washer for washing cars

If there’s one thing we enjoy about owning a car it’s having a clean car. There’s nothing I hate more than dirt on my car but I hate car washes. The only time I use them is during winter. When summer rolls around I use a power washer on my car. Here we will talk about the best power washer for cars.

Top Picks for the Best Power Washer for Cars

Sun Joe SPX3000 Electric Pressure Washer

Up to 2030 PSI with the Sun Joe SPX3000


  • Dual soap tanks
  • Safety lock switch
  • 5 Quick-connect spray tips
  • 14.5 amp motor
  • 2030 PSI
  • 2-year warranty

The standout feature of the SPX3000 is the ‘Total Stop System’ which will shut the pump off when the trigger is not pulled. This will prolong the life of the pump. This is a feature that hasn’t always been on pressure washers. It hasn’t been on the older power washers I have used in the past but I wish it was.

There are two soap tanks on the Sun Joe SPX3000 to store two types of detergents. You can have one tank for car wash soap and another for general purpose cleaning. Each tank will hold 0.9 L of soap. Nice that you don’t have to worry about changing soap between projects.

Included in the box are 5 quick-connect spray tips: 0 degree, 15 degree, 25 degree, 40 degree and soap for light, medium and heavy duty cleaning.

The large pneumatic tires on the SIMPSON power washer are a big improvement over the Sun Joe. These tires are better over rough ground if you have an uneven yard.

There is a lack of a soap tank on the SIMPSON power washer. You will have to purchase a separate adapter if you need one.

Overall the SIMPSON MSH3125-S is the top choice for gas-powered pressure washers. It has over 1000 reviews with an average of 4 stars out of 5.
