I used a soft cloth auto car wash with tracks on my last e90. Needless to say, there were fine scratches in the paint. This winter, we have had more salt and sand than I can remember. I hit up the laser touchless every couple if weeks. Sure there is still a very thin film on the car and it is not completely clean, but it does seem to get most of the sand and salt off. I think this is the way to go in the winter, and handwash in the summer, especially with JB!
