Not that I necessarily believe a giant corporation but this is what Cargill says about Clear Lane:
"Reduced corrosion. Longer equipment life. Harmful rust and corrosion that results from extensive salt use often diminishes the life of application equipment. The patented PNS-approved corrosion inhibitor found in ClearLane® enhanced deicer is better than traditional road salt for your fleet, helping extend the life of your application vehicles."
