What is this product?

Ice melt products: rock salt (NaCl), calcium chloride (CaCl2), magnesium chloride (MgCl2), potassium chloride (KCl), and urea. Rock salt is cheapest but damages concrete, kills vegetation, and irritates pet paws. CaCl2 works to -25F but is more corrosive to concrete. Pet-safe ice melts typically use urea or propylene glycol-based formulas — but 'pet safe' is unregulated. Environmental impact: US applies 24 million tons of road salt annually — contaminating waterways, killing freshwater organisms, and raising sodium levels in drinking water wells. Concrete damage: salt scaling and rebar corrosion.
