Abstract
Abstract An alkaline, non-phosphate, ice melter composition containing common deicers and anticorrosion chemicals (used to prevent base metal attack in acid pickling baths) and which is substantially less corrosive to steel than ordinary tap water. The composition will be environmentally safer and greatly reduce the corrosion of steel bridges, parking decks, railroad station platforms, guard rails on roads, other metal structures, and the like.
