Touchless car washes that spray liquid after liquid to “presoak”, “power wash”, “sealant”, “protective coating” and other things, how does this work? Does spraying X liquid after Y liquid after Z liquid really clean and do anything to protect a car’s paint?

Question

Edit: as in no need to really dry/wipe off the prior application? Or is it really just a soap and wash that gets most of dirt off?

Answer 1

It is basically soap, hot water, and some wax dispersed in water. Yeah, they could just call things what they are.
