Abstract
A low-temperature corrosion inhibited deicing composition is disclosed which comprises a major portion of magnesium chloride and an effective amount of an inhibitor including a polyphosphate salt to reduce corrosion, or a solution thereof. The solution form is preferred. Additional preferred aspects are provided where the inhibitor also includes a zinc-containing salt, and where the deicing composition is free from (or at least substantially so) chloride ions other than those due to the magnesium chloride. A method for low-temperature deicing of bridgework is described which includes the use of the inhibited deicing composition.
