When you drive from the end of the pavement out on the salt, it will get everywhere, It's very hard to get the underbody clean, if not your car will start to corrode in all the cracks and crevices in a few years, There is usually brine a few inches below the surface, that keeps the surface cool, better for racing tires. it will coat everything. sometimes there are a couple guys with a pressure washer that will clean your car for a few bucks before you can get it up on a hoist for real cleanup. Best to drive slow on the salt so you don't throw so much on the chassis.
