Road salt in winter is used to de-ice roads, but it can also create rust on the undercarriage of your car. After a serious storm, be sure to take your car to a car wash -- which is the most water- and energy-efficient way to wash a car -- to have the salt residue washed off, then opt for additional undercarriage cleaning. A wax seal now and then will also help create a protective barrier, which prevents the de-icing mixture from deteriorating your car.
