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

As a detailer, I can tell you that touchless wash doesn’t get the car completely clean. It might get the most visible dirt off, but without physical contact there will always be a road film left. I only recommend washing by hand.
