Winter Melt ice melter is specially screened to provide a unique blend of large and small melting crystals. The small crystals melt ice quickly while the large crystals provide long-lasting action, boring through the ice, breaking the bond between ice and pavement. Working at temperatures of 5° F and higher, Diamond Crystal® Winter Melt® ice melter is a cost-effective alternative to more expensive blended products.  Available in 10, 25, 50 and 80 lb. bags.
