How To Start A Pressure Washer

Are you tired of a long household chore list of washing and cleaning in your family? These tasks are much simpler when you know how to start a pressure washer.

A pressure washer is a great assistant not only for many house owners, but also professional cleaners, or even a lazy person who just wants to do the cleaning quickly.

No matter who you are, you still get your work done well, safely, and efficiently by using a proper pressure washer. Let’s check this article out to learn more about it!

Things To Consider Before Starting A Pressure Washer

Even though this machine helps to get your cleaning and washing jobs done quickly, using it can be dangerous when you are unsure of what considerations before using it.

Keep in mind the following things that users would not normally think of, including washer types, technical terms, and appropriate nozzles.

Types Of Pressure Washers

In the market, there are two basic pressure washers: Electric and Gas. You can find some differences in their performance below.

Electric Pressure Washer

electric pressure washer

  • Washes small vehicles like cars or motorbikes.
  • Cleans grills, furniture, or floors
  • Removes stains or dirt

Gas Pressure Washer

gas pressure washer

  • Deep-cleaning concrete or metals or large areas
  • Used for washing big vehicles like boats or trucks
  • Cleans siding, fences, or wood decks
  • Paints stripping

Be sure to consider the tasks you need to do and decide which machine is more suitable.

If you want to do some convenient and light-duty jobs, go for an electric pressure washer. And the gas pressure washer will be the perfect choice for high-intensity or heavy-duty jobs.

Some Important Technical Terms

The two factors (PSI and GPM) mentioned below affect the cleaning performance of the equipment.


  • Delivers 1,300 – 1,400 PSI (pounds per square inch)
  • Requires 1 – 2 GPM (gallons per minute)


  • Delivers 2000 – 3000 PSI
  • Requires 1-3 GPM

The PSI is the force the water will have on the surface. If the PSI is too low, it is harder to clean the surface. However, you can badly damage the surface if the PSI is too high.

And the higher the GPM (the amount of water is released), the faster the cleaning process will take and vice versa.

To avoid bad damage and problems to the surface you clean, selecting proper equipment and understanding the above terms are essential before using it.

Choose Right Nozzles

In addition to the PSI and GPM, the other factor that needed to be considered is the nozzle.

Depending on your cleaning task, there will be several nozzles that spray different pressures and angles.

Five popular nozzles

0 degree (Red)

  • High and strong pressure.
  • Small, concentrated stream of water.
  • Removes tough stains from metal and concrete.

15 degree (Yellow)

  • Strips paint or mildew.
  • Removes dirt from sidewalks.
  • Can be used on most surfaces.

25 degree (Green)

  • Flush debris from the hard surface.
  •  Good for furniture, cars or boats.
  • Good for pre-wash rinse.

40 – 60 degree (White or Black)

  • Cleans large areas fast.
  • Ideal for fragile surfaces (blinds, windows, or pots).
  • Rinse off the detergent.

Tips: If you do not know which nozzle to use, test on a small area with a low-pressure nozzle like 40 or 25-degree. Then adjust the distance or nozzles if needed.
