How exactly does road salt cause cars to rust? | Hemmings
2014/1/22· As a side note, sodium chloride isn''t the only road salt available, nor is it the most effective; it''s simply one of the cheapest. Other road salts, like calcium chloride and magnesium chloride, involve more complex molecules that distribute more ions when they dissolve in water, further lowering the freezing point of water.
