edit: high pressure sprayers + fairly strong detergents. The touchless car washes here (delta sonic chain) use two overhead towel bars to get the top of the car. There is no possible way these touch all down the sides of the cars--yet the car is "clean" after. I've never seen the film left over at the Delta washes, so it's possible that the chain uses a slightly different system (what i'm describing) then what places in your area have. You also live where the "worst case scenario" isn't going to be nearly as bad as a Buffalo-Rochester "worst case scenario."
