100% Salt & Chloride Free Ice Melter. Safe for People, Pets, Property, and Planet. Safe Paw Pet-Safe Ice Melter is like no other product on the market. It has a patented dual-effect compound, made up of a crystalline amide core infused with special glycols. This non-corrosive composition gives Safe Paw a two-way, timed-release action. The liquid component starts melting ice instantly while breaking its surface tension. This allows the crystal-core to quickly penetrate and destabilize the ice, speeding up the melting process. Safe Paw actually attracts heat to make it even more effective, but does not give off heat. This “endothermic” reaction takes advantage of solar effect and provides extra melting power during daylight hours. As an added feature, Safe Paw leaves an invisible protective shield that prevents ice from sticking to the surface for up to three days, making shoveling much easier. Safe Paw works in weather as low as -2°F. Pets: Safe Paw does not burn pets feet and their digestive systems are unaffected (if consumed) People: Children are also safe Plants: Vegetation stays alive and healthy Property: All surfaces, including pavers and wood decks, remain in great condition
