|Calcium chloride is the most powerful of all common de-icers used for melting ice and snow on sidewalks, driveways, parking lots, and streets. The exothermic (heat releasing) reaction when solid calcium chloride goes into solution makes it the de-icer of choice. No other product melts more ice, and melts ice faster, than calcium chloride.
Calcium chloride has the lowest freezing point of all the typical de-icers including sodium chloride, magnesium chloride, potassium chloride, and urea.
Calcium chloride is an essential part of any winter road maintenance program and will provide a safe surface for both traffic and pedestrians.
Both liquid and solid calcium chloride can be used for de-icing. The selection of a product will depend on the local conditions and available equipment.
