Hey guy,

I just watched the latest Garry Dean video about his air injection system. I really like the concept but do not want to carry a compressor around in my van.

I was thinking, could it be possible to hook up a tank of ONR solution to a pressure washer? I know the ratio of product vs air would be lower than using a compressor with a paint gun but besides using more product, it would very likely be more effective at cleaning.

The question is, would it damage the pressure washer?

Also, would free flowing from the tank be enough or would there be a need for a pump?

I am using a 1600 PSI pressure washer. I also have a 1800 PSI bigger unit as a backup that I leave at home.

I was thinking about putting a small tank (10 gallons maybe) on the top of my Caravan with a 50 foot hose.

What do you guys think?

If you don't know what I am talking about, here is a link to Garry's video:

That sounds like a huge waste of product, even with a small electric PW, you would be going thru over a gallon per minute.

Some of the Karcher PW's can draw from a standing source of water/solution.

If you are getting out a PW...I don't see the sense of doing a Rinseless.
 
Elaborate tornador at higher pressure.

The carpet cleaning guys have a tool called an inline sprayer that can be connected to a truck mount system, but similar to a foam cannon, it will dilute the product.

I've seen people use a hand pump pressure sprayer and modify the air release to connect to an air compressor, much closer to this set up, but having a bomb in your hand is a little risky.
 
I think the benefit of the "air injection" is that it doesn't dilute the product with water. I have one of those spray guns attached to my compressor and don't find the need to use as high a pressure as he does to achieve that effect.

You can just use a pressurized spray tank like they use to spray garden pesticides and I feel like you will be achieving the same goal.

I would be using only ONR as a source, no water. So no dilution.

Why do this if I am gonna do a rinseless? Here is my thought process: Right now I usually do this process on dirty cars 1. Pressure rinsing 2. Foam coat with the pressure washer 3. Pressure rinse 4. 2 bucket wash 5. Free flowing water rinse 6. Sidekick blow of water out of crevices 7. Drying with microfiber towels.

So if I would remove most of the dirt using Garry's method, I could do an ONR wash instead and save a lot of time.

I have several sprayers with pumps and I don't feel they have anywhere near the pressure of a pressure washer or a compressor. I doubt they could remove all the dirt like those 2 methods can.

Sure I would be going though probably 4 gallons of ONR to do this. So that's 2 ounces of product or about a dollar for me. No big deal if it can save me 20 minutes off the wash process. What I am really concerned about is the compressor itself. It's designed to spray water, no ONR and I am afraid it could damage something. I know you can't spray soapy water but ONR doesn't create any bubbles or anything.

Hopefully someone will know.
 
I am also intrigued with the GD Injection system for washing a vehicle.
I gotta say, especially for a mobile detailer, that is a lot of equipment and work to put into something, that a steam cleaner can essentially do already.

The first sprayer I linked above puts out 120 psi--that's ~what air pressure Garry was using in that video.

120psi pump? That's going to be a massive difference between 120psi of air.
I've been using an old gravity feed spray gun (non-hvlp) for over 3 years now filled with D114, ONR etc and it works very well for blasting dirt out of the nooks and crannies. I'm not mobile though and have a huge air compressor at my shop. I call it the "spray gun hooked to my compressor system".
