I have taken mine to an auto carwash (But touchless only). We also have a Mikes Carwash and someone always sprays the back of cars to make sure they are clean. The roof behind the wind deflector does not get real clean, so you may want to spray that off before you go through. You won't have a problem with your antenna because they are flexable. Only power antennas should be put down before entering a carwash. Hope That helps!
