Winter road salt is critical for preventing accidents and keeping roadways safe. Salt lowers the freezing/melting point of water, making it a fast and inexpensive way to melt slippery snow and ice on the road. Unfortunately, salt is also a highly corrosive element, and its affects can be extremely damaging, leaving your car with the road salt blues.
Road salt exposure throughout the winter can wreak havoc on the metal components of your car. Most vehicles have an exposed underbody, so most salt damage occurs underneath the car, where it goes visually undetected. Rust on essential parts of your vehicle can leave you with huge problems ranging from brake system leaks to frame damage. While your rubber tires will suffer little or no damage from salt, your wheels are highly vulnerable, since the metal areas of your car are most at risk for salt damage.
Fortunately, the coatings and paint finishes used in today’s automotive manufacturing do a much better job of providing protection against salt damage. And since the process of salt leading to corrosion and rust takes awhile, you have time to undo salt damage potential.
The best way to protect your car from road salt corrosion is to take it in for regular washings during the winter months . Base the frequency of your car washings on how much salt and road sludge it is exposed to on a regular basis. If you have really expensive wheels, consider swapping them out it the winter months, since salt is particularly hard on chrome.
For further protection, make it part of your fall routine to wax your vehicle. Waxing in the fall will help make your winter washes more effective.
