“The inherent corrosiveness of deicing salt is often ignored when material decisions are made. The International Molybdenum Association’s new article "Deicing Salt - Recognizing The Corrosion Threat", can be downloaded from their website. It documents the growing international use of deicing salt and hightlights new research showing that it travels much further and stays in the air longer than previously thought. Case studies illustrate deicing salt related corrosion of common architectural metals and emphasize the importance of appropriate stainless steel selection."
