Corrosion can occur to your vehicle due to salt accumulating on it. The main way to combat the problem is to keep your vehicle washed and clean. This will remove salt deposits that can cause pitting or rust to exposed metal on your vehicle.
Salt especially becomes a major factor during the winter. This is due to road crews reducing ice buildup on roads by spraying a salt mixture onto the surface of the road. After you wash your car make certain to allow your vehicle to fully dry. Moisture and salt cause rust. Allowing your vehicle to fully dry after washing it will keep water from pooling in hard to reach areas on your vehicle.
Another preventive measure to combating rust is to use a protectant on your vehicle. There are products you can purchase that create a barrier between the salt and your vehicle.
