How exactly does road salt cause cars to rust?
How exactly does road salt cause cars to rust? by Daniel Strohl We here in the northern states get exactly two things from combining cars and winter: good wintertime driving stories and rust. Both come courtesy of snow, but not directly; the former involve driving skills (or lack thereof) as a catalyst, while the latter involves road salt as a catalyst. The fact that road salt causes vehicles to rust out – sometimes after just a couple of winters – is something everybody knows, but the exact process isn’t quite as simple as steel plus salt equals rust.
