This stuff is good. It is fast and easy and especially useful when it is cold out. Personally I stick with water washes except when it is cold, a drought or I am somewhere without a water connection. Many professional detailers have switch fully over to ONR though, it is good stuff.I was wondering the same thing if it works at all, or it's just some marketing scheme, until I had to wipe some old bird crap. Took it out with first wipe.
