With so many snow storms this year you may wonder what effect the liquid de-icers have on your automobile. CDOT has published a Liquid De-Icer Fact Sheet to explain why they are used and what you should do about your automobile. Briefly, it says that liquid de-icers are easier on your car’s paint and windshield and are less corrosive than sodium chloride, which has been used for years. You should still wash your car frequently to remove any type of salt, whether it is magnesium chloride or sodium chloride.
Our library has cataloged CDOT’s research reports on de-icers for those who want more background. Some are available online, but all can be borrowed in hardcopy from our library.
