New to detailing and have enough now for a pressure washer. I am looking to get one that's 2,200 psi. Is that too strong to use on a vehicle? I'm worried about chipping paint or damaging the vehicle somehow. I want the higher PSI to also maybe get into pressure washing houses and decks etc.
 
That should be fine,I have a 4000 psi Honda pressure washer that I can regulate the pressure down to 200 psi and up to 4000 if need be.you won't need all that pressure to do a car,maybe wheel barrels or floor mat blasting.

2,200 can chip paint, I have a 2,000 psi electric pressure, and I have chipped paint with it. But it was on my friends beater car that already had chipped paint.

If there is a chip the pressure washer lifts it and chips and cracks more.

Just keep a safe distance from the car and respect the machine.
 
And use the broader nozzle to keep the pressure under control. Never use the pin point sprayer as it can actually damage the paint and even lift off emblems.

:iagree:Different nozzles will vary the spray pattern therefore reducing the direct pressure on any one spot. My gas powered PW doesn't have an adjustment for PSI, so therefore I vary the pressure with the various nozzles.
 
Pressure can also be reduced on many pressure washers by using a nozzle with a larger orifice. (It depends on the type of unloader valve the PW has.) Basically think of the pressure washer as a constant volume pump. Increasing the orifice size of the nozzle with the same flow rate of water results in decreased pressure. There are charts that can be used to assist in selecting the orifice size.

NOTE: The pressure rating on the pressure washer is the maximum...do not try getting more than that pressure by selecting a smaller orifice!
 
you don't need that unless your washing 100's and 100's of cars a day.
I've always use cheap little electric ones and they work fine for years and years.
I have never seen the reason to spend thousands of dollars to wash one car at a time.
You only need a little pressure and your done. I've never come across anything my little pos pw couldn't handle.
 
I used to have a monster gas Honda pressure washer and for me, what a total pain in the wazoo. Just moving that beast was a project unto itself. I now have an electric 1700 psi and that is perfect for washing cars and handling pretty much everything around the house. I dare to say, more is not necessarily better. Risk vs reward.

What is a pressure washer called that you can switch the psi up and down?
 
I have a Green Works 1700 psi Electric, and a Generac 3200 psi gas with Honda motor and I will always use the gas!! Just be careful and any paint in question stay away from.

The black knob in the picture will adjust the pressure from basically the input hose pressure to max of the machine. Mine is rated 3100psi and 2.8 gpm. The picture is of my model and the 4200 psi model is the same way. Most pressure washers that have this style of pump will be the same. I have found the only time I need to turn it down is to start, if it is set to max the pump becomes too hard to turn to let it start on the 1st or second pull. So when I turn it off I will turn it all the way down open the throttle all the way and turn the choke on and shut off the gas so all I have to do to start next time is turn on the gas.

I also use the 40 degree tip which has a nice fan which helps with the rinsing.

I prefer 2000 anyway. If anything, just have the nozzle further back

I used 2,700 psi when detailing professionally but now use 1,800 psi electric at home. I would gauge my distance with 25 degree tip on the 2,700 and had great performance with it. 1,800 feels like a plastic toy.
