To be clear, I thought I would not have to touch the vehicle by hand when I followed the example in the advertisement. So I followed the advertisement and the put the foam on, let it sit, and then spray it off and it would be clean and shinny. It did not completely clean my vehicle, a lot of dirt did come off but left a dull finish when it dried. I think if I had hand dried it it would have been better. So it is a good product but not excellent.
