THE NICER DE-ICER: Thanks to its anti-corrosion formula that contains CMA (calcium magnesium acetate), Melt Premium Enviro Blend melts to -10°F and is safer for vegetation, concrete, and metals than pure rock or chloride-based salt. The formula works on surfaces longer, requiring less product, and won't dry out or irritate skin, so no protective clothing is necessary. Plus, it doesn't track onto your home's floors or carpets or leave slimy residue behind, so you can safely tread your footwear on any treated surface without worrying about damaging your shoes or home. Finally, the green-coated crystals not only serve as a visual indicator to observe the melting process in action, but also help you visually measure and dispense just the right amount to ensure the most cost-effective use of the product.
