Natural Alternative Ice Melt is a non-toxic and biodegradable blend of ingredients designed to be hard on ice and snow yet easy on sidewalks, vegetation and the environment. It melts ice to -16°F, is not toxic to fish and it is safer for pets. It is listed with the Pacific Northwest Snowfighters (PNS) for reduced metal corrosion. It does not become slippery when wet and does not leave a greasy residue to track in on floors. Apply the product prior to snow storms to create a brine. As soon as it comes into contact with moisture, it will minimize ice and snow accumulations and thawing and refreezing cycles.
