Green Earth Ice Melt is a blend of deicers with a corrosion inhibitor. Blend of Potassium and Sodium Acetates and Solar Salt. Deices faster. Pound for pound #482 requires less product to achieve the same results (30-50% less product is required). Effective down to -25oF. Safer than Rock Salt and Calcium Chloride on concrete and vegetation. Leaves no oily residue. Dissolves into a brine faster; reducing the amount of product that is tracked indoors. Much lower corrosion potential.
