I understand how it may not make sense to some, but I want to try it anyway. I'm going to use the same chemical with multiple passes for more dwelltime and cleaning power. I think by upping the chemical strength and using less chemical there is more chance to damage chrome trim paint etc. At a $20 price point I don't mind spending more on chemicals and water per car. Since No one has created the " chemical" magic bullet for cleaning in a touch free, Why is it so crazy to you guys to load on extra passes of
soap for more cleaning power and dwell time?
