Road salt in the wintertime is used to de-ice roads, but it can also be a leading source of rust for the undercarriage of your car. Be sure to bring your car to a car wash -- which is the most water- and energy-efficient way to wash a car -- after a harsh winter storm to have the salt residue washed off, opting for additional undercarriage cleaning. A wax seal now and then will also help create a protective barrier on the outside of the car.
