For at least this one winter I've decided to drive my car through the winter, rust risk be damned. I will have it checked out at my area's premier BMW body shop (Sansossio's) come spring to identify any early rust spots in hard-to-find places. In the meanwhile I'm wondering how often I should get it washed. I live in a condo with no access to my own hose. I've heard that most car washes don't recycle their salty water. (I'm not sure that's true though.) How often do other rust belters get their cars washed if they drive during the winter? What's recommended? I've got a touchless car wash not too far from me, and I don't mind going there every week if I need to. I don't drive the car when the roads are real wet and/or freshly salted.
