Calcium Chloride Home : Frequently Asked Questions : Dust Control Application Questions

Is calcium chloride used for dust control corrosive to vehicles?

Noticeable vehicle corrosion is not likely to be associated with dust control applications of calcium chloride. First, the application rate is relatively low, so there is not much calcium chloride available to come into contact with passing vehicles. Second, the calcium chloride tends to remain in the road bed. If it didn't, it wouldn't control dust very well because it would disappear from the road after a short while. If it is suspected that a vehicle has come into contact with calcium chloride, a basic wash of the vehicle will remove this highly soluble salt.
