Pressure Washer Soap

[mike_svt]

I've searched these forums for this information, but I have been unable to find an answer. Is there a Meguiars soap product that I could use in a pressure washer? The washer that I'm looking at has a built-in detergent resovoir. I would like to use NXT soap, but I think it will be too thick. Any suggestions????

Hi mike_svt,

I don't know the answer to that question. But I'll see if I can get an answer for you...

Hi mike_svt

I just purchased a Karcher 1750 psi pressure washer and intend to use NXT car wash. I called Karcher to ask about using
my own car wash soap instead of their brand.

I was told it would be OK but :
- DONT FILL SOAP TANK WITH MEGUIARS CAR WASH SOAP !!!
The soap must be diluted with water and the dilution
rate can only be obtained by trial & error. As its getting a little cool up here in the Great White North I wont be able to experiment with the dilution rates until spring.
I plan to start with 1oz of NXT soap in reservoir of water and
see how far this goes on the car & suds produced. Depending on the results I will adjust the ratio of NXT soap to water in sprayer detergent tank.
Perhaps someone in the warmer States ( or BC

) can experiment with the soap/water ratios & post their findings. Someone out there must have tried NXT car wash in a pressure sprayer.

I have tried shampoo thru pressure washes, and learned several things:

It wastes soap/shampoo.
Soap scum will build up in your machine.
High pressure isn't good for paint!

We only use the PW for wheels, Wheelwells, tires, doorjambs, and floormats. And even then, we apply the cleaner to the surface, allow it to dwell, and then spray.

I recently picked up a Husky 1800 Pressure washer with the detergent tanks. Great machine by they way cleaned the windows on the second story of my home in a few minutes.

Being the GENIUS that I am I just FILLED one of the detergent tanks with NXT Wash....and nothing happened...Then I realized ...it wasn't being sucked into the the machine...so DILUTION IS A MUST!!!!!!! fortunately I was able to pour all the NXT Wash back into the bottle. I read on another board that there are different ratios for wash dilution depending on the actual car wash product being used. NXT was something like 133:1 - not sure how they came up with this ratio, however guy who posted claims it car soaps up well with this mix

Well, the official dilution rates for Meguiars soaps (except Hyper Wash - 400:1) is 128:1. So I guess 133:1 is close.

Now I am not sure how adding that already diluted soap to the stream through the pressure water changes anything. Kind of the same situation as with the foam guns.

[mike_svt]

I just picked a value of 2oz NXT soap to 1 gallon water. I keep a gallon of the solution in an old water jug and just add to the resovior as needed. I forget how many oz's are in a gallon...64 or 128? Either way, I think I'm a little concentrated but it works good for me!

[Murr1525]

Yup, 128 ounces in one gallon.

So 128:1 is one ounce of soap per gallon of water.
