Why Is Rock Salt Used as an Ice Melt?
Salt is used as an ice melt because it is the most available and most cost-effective safe deicer. The primary type of rock salt used is mined from the earth. Solar salt, which is evaporated from seawater is also used. Salt is used to keep snow and ice from bonding to the pavement and to allow snowplows to remove ice and snow as quickly and efficiently as possible.
