When layers of thick ice and snow seem impenetrable on a cold winter's day, you need the heavy-duty melting abilities of Share's TETRA-CHLOR. This amazing ice melter derives its name from the four potent chlorine ingredients designed to quickly dissolve ice; magnesium chloride, potassium chloride, calcium chloride and sodium chloride. Both the magnesium chloride and the sodium chloride work together allowing TETRA-CHLOR to perform in temperatures as low as -20°F. In addition, the calcium chloride and magnesium chloride provide fast melting action to dissolve ice and snow within minutes. To apply TETRA-CHLOR, simply scatter it over ice and snow using a spreader or by hand while wearing gloves. And unlike the rest of the competition, TETRA-CHLOR does not leave behind a chalky residue that can be tracked onto floors and carpets. To quickly and efficiently eliminate the slick dangers of ice and snow buildup, you can rely on the strong melting action of TETRA-CHLOR from Share.
