Ice B’Gone Magic is safer to use on concrete, is less corrosive, may not harm curbside grassed areas or plants, and continues to melt ice to below -35F° if used as directed. Ice B’Gone Magic starts out as ordinary rock salt, which is then treated with a liquid, agricultural by-product of the distilling process blended with magnesium chloride. This patented liquid is trademarked as Ice B’Gone Magic and dramatically transforms rock salt into a new de-icing material. Ice B’Gone Magic is a highly effective de-icing agent made from a patented blend of magnesium chloride and condensed distiller solubles. It is non-toxic, bio-degradable and has a corrosion index lower than distilled water. The benefits and results of treating your salt stockpiles or your sand/salt stockpiles with Ice B’Gone are amazing!
