You probably know this after 17 years so it's a tip for your viewers. Leaving the pressure washer running without water flowing through the nozzle will heat the pump to unsafe temps. This will be the premature death of the pressure washer. The simple remedy to this is to let fresh water in the pump by pulling the trigger two or three times per minute. Plus shutting the pump off like you did when it isn't being used.

That being said, I know nothing about polishing cars. I've been binging your videos for a few days and have found a lot of great info. THAN YOU.

I have a 20 yr old van that has been stored outside and the roof has probably never been washed. I'm determined to get it clean, polished, and sealed before I cover it with solar panels and put in a roof vent. I think I'm on the right track but any specific suggestions from you or your viewers are welcome.

I have a 3600psi pressure washer that I use mainly for driveways and houses and have never damaged paint on a car. If you don't have larger orifice nozzle tips, high pressure pumps have an unloader valve you can turn.

I only use my 40 degree tip for cars on my pressure washer. It is a ryobi 3800 psi gas washer. I learned several years ago how to properly use a pressure washer. I worked for a equipment rental company and we had a 5500 psi hot washer and washed everything with it. It was a huge commercial grade unit. We mainly kept the 40 degree tip on it too.

im trying to get started in this field and im doing some research and videos like this and people like you make it 100x easier thank you

We do 99% rinseless washes however when needed we use an Active VE52 with tips that have a 4.0 nozzle orifice size to bring our pressure down to 1050psi.@ 1.94GPM. It also helps lower the amperage draw it has so we can use it with a smaller portable generators 13.3A outlet trip limit.

Mine is 3100. Not bad. I’m careful. Overly OCD about my vehicles.

I'm kind of new to pro auto detailing but wanting to learn more n more. Just bought my first BMW so I want it to look perfect every time I look at it. I actually enjoy the detailing myself but there's a lot I need to learn which is why I'm here. Been watching several different detailing youtubers but decided to stick with Josh here because I feel like he's more into helping / educating than selling a product so I'm subscribing to the channel. Cheer's!!

You might be able to test spray force (somewhat) more scientifically and repeatably by putting some kind of protective plate on top of a bathroom scale, and then directing a stream of a specific width at the plate to see how much force is being exerted on the scale, then divide by area of spray to get ‘PSI on target’. The “impact width” on the box appears to be about identical between the two nozzles at the moment of penetration—the 15 degree tip just produces that impact width at a greater distance. I think the droplet velocity and flow rate at the nozzle should be equivalent between the two and dictated primarily by the orifice size, so I think it follows that the force on target is basically just a function of the area across which the spray is distributed.

Right on josh I have the craftsman 2100 for the house I have 2.0 orifice and around 1800 psi for my stubby gun I have 3.0 getting around 1000 psi for the vehicles thanks

A pressure washer is not needed to clean a car that said in 10 years IV noticed anything over 2000 psi will blow off paint if you hit a rock chip so ya if your a pro you can get away with a higher psi but pro or not one mistake that paint is gone no more than 2000 psi even with 2000 you must be careful I think we all blown off paint at least once

mattjones

Thank
Just got a new one from Amazon and it says 4000 PSI & 2.5 GPM...
Need to know this because I was reading to abandon it....👍🏽😉
Love the

I probably run mine in general at about 1400 or so. No issues....I go a little harder on my tires.
I think as long as your not going with crazy pressure the big caveat is the age and condition of the it ALREADY has some rusting or has the top coat erroded of course a pressure washer is a bad idea...newer cars though can take a good pounding...not that you should but I generally dont worry to much as long as your in a certain range.

On a side note my brother who owns a kennel had me pressure wash some tires that are painted that are out in the dog yard.
I was using a 2400 psi washer with a 15% nozzle at very close range and it was an absolute chore to get the paint off it....It was pretty strong pressure cause at one point I got my finger in the way and a couple days later I still have an open cut that I need to cover....It =broke my skin in less then a second lol.

In hindsight we know that we should do rinseless or waterless washes on the classic cars.
Also can you do the PSI testing on some panels you might have laying around? I would like to see at what psi you can strip paint off of a car. Or in this case a panel from a car.
Thanks for sharing.
