THE NICER DE-ICER. Melt away slippery ice and snow build-up this winter with KIG12 Keep It Green Snow & Ice Melter, a unique mix of CMA (calcium magnesium acetate), sodium chloride, and a time release fertilizer. CMA is an anti-corrosion agent that's less harmful to metal than pure rock or chloride-based salt. It works on surfaces longer, so less product is needed, posing a lower threat to your plants and vegetation, too, and can be conveniently dispensed directly out of the bag or into a handheld or wheeled salt spreader.
