Snow and ice are headaches for motorists and pedestrians. To promote public safety, deicing compounds are used to melt ice and snow on sidewalks, driveways, and highways. While deicing materials are necessary for safe winter travel, they can damage automobiles, concrete surfaces, and landscape plants.
Most deicing materials are salts that melt ice by lowering the freezing point of water below 32 F. However, a few other materials can be used on icy and snowy surfaces. Advantages and disadvantages of several commonly used deicing agents are discussed below.
