Soft Wash vs. Pressure Wash

Do you use the same equipment?

Can I adjust a 4.8 GPM @ 3000 PSI down to perform a softwash?

Yes, just use larger tips.

that should do the trick

Once you have your pressure washer dialed in to the psi you want, " IE " 3000 psi, you should not mess with the unloader. You should change the PSI with different size tips like stated above.

Do not set your unloader to a psi. It should be set for max flow. If you are using a gauge to set your unloader you are doing it wrong. Bingo on changing psi with tips

What kind of psi should I be seeing with certain tips?

Who are you?

Just someone who wants to learn about soft washing to offer it to customers that may be nervous about high pressure. Close the sale with another option.

That is me.

Crude video but its all about the tips.

Do you recall which tip that one was? I can play around, I have a pressure guage.


Search “nozzle chart”. Learn to read it. You don’t need a gauge.

What pressure do I need to be at to be considered Soft Wash? I will study the charts tomorrow and figure it out an post my answer to the correct nozzle.

That is a valid question. It can have many answers. Soft Wash is more about the detergent and the process doing the cleaning as opposed to the pressure doing the cleaning. I suppose it would be under 500 psi but many clean at pressures well under that.

I generally tell my customers that soft wash means that I can put my hand in front of the water stream coming from the tip with no harm to my skin.

So if I read the chart correctly. 4.8 GPM @ 3000psi. The Nozzle orifice size is: 5.5 with a hole size of .060"

I don’t understand how to determine which nozzle to use to change my pressure to 500 psi to do a softwash.


  1. Pick the pressure desire.

  2. Find your flow

  3. Find nozzle size

If you go here THESE KIT INCLUDE 4 NOZZLES & A 4 WAY HOLDER. (2) 0 DEGREE, SOAP & RINSE HIGH AND (2) 25 DEGREE, SOAP & RINSE LOW THE 2-3 GPM KIT INCLUDES: 0030(SOAP HIGH),0010(RINSE HIGH),2530(SOAP LOW),2510(RINSE LOW) THE 4 GPM KIT INCLUDES: 0040(SOAP HIGH),0010(R, you will see that Bob shows a 40 tip for soap and a 15 tip for rinse for a 5gpm unit.


13, and for example to make sure I understand this, if I wanted to do let’s say cut my pressure to 1500, would I use a 10?
