THE NICER DE-ICER. The FN40 Frosty’s Nightmare® Snow & Ice Melter is comprised of specifically sized ice melt crystals designed to quickly de-ice pavements, driveways, and other road surfaces, making them much safer and easier to traverse. Frequent use throughout snowfall periods prevents ice from forming on ground surfaces, too. Can be conveniently dispensed directly out of the bag or into a handheld or wheeled salt spreader.
