Groundworks Natural Icemelter

Regular old rock salt will melt ice, but it's terrible for pets, plants, sidewalks and decks. GroundWorks is a fertilizer-based formula that quickly melts ice and snow without harming the environment. Effective all the way to -9º F, it keeps working even after it dissolves, to prevent refreezing and further accumulation. Safe for use around children, pets and vegetation, it won't harm concrete or leave a messy residue. Unlike other ice melters, GroundWorks has a unlimited shelf life. One 12 lb. jug could last for years!
