I have never tried the waterless wash. Something about rubbing dirt around on the paint doesn't sit well with me. Maybe for a quick detail but I don't see how this can be better than using a pressure washer to blast off and away the heavy particles before even starting to wash? I know people swear by it, and it makes sense in freezing situations, but is it actually better?
Change my mind!
I agree, I'm all for waterless washes but not going to risk the scratches if the car is dirty enough. I think many people who use waterless washes might wash their cars often enough where it doesn't build up as much dirt since it's quick and can be done in 10-15 mins. ONR and Chemical Guy's V07 are my favorites but if my car is dirty enough I always give it a traditional wash first. Then wipe to dry with a waterless wash or detailer sprayed on the cloth.
