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

Btw you can achieve same thing with an electric pressure washer, an inexpensive foam canon, car shampoo and a blower.

And it is much cheaper too.

Plus you can use your hands to actually clean any deep stains or dirt.

Takes less than 20 minutes if you do it regularly.
