Portable Spray Car Washer Soap Question

[st-dubtx]

I recently detailed a car that has been regularly washed (twice per month) by a man who has a portable pressure spary rig mounted on his truck. He does individual cars as well as car lots in town. He just sprays and chamois the car.

Here's my question, generally, what type of soap is used in those machines?

I am guessing that it is stronger (less gentle) than most, but what has been your experience with this? Or, for those of you who have similar set ups, what do you use?

This information will help me advise my client on the best action to take regarding his car.

Thanks for the input/advise.

Re: Portable Spray Car Washer Soap Question

It depends.

Some people around here will use pressure washes, even with different soap attatchments, but the people here will tend to also use a mitt/sponge to agitate the surface, and be willing to take their time. So a milder soap can be used, which any of Meguiars soaps are.

But if a person simply wants to spray on and walk away with a clean car, much like at a carwash, it is going to need to be a much stronger soap. A soap that strong could remove wax, dull the finish, and if any particles were left behind, it could cause swirling during drying. Assuming the chamois is even clean/good quality.

It depends.

I think I would go with the above answer, but, just wanted to share this link from Megs UK. I have zero experience. I don't know if this info is any good, but here it is:

I like the "it depends" answer because it takes in to account what you are actually working on. Wow, what a concept.
