Prestone Driveway Heat is a jug of calcium chloride pellets that melt ice down to -25°F. Calcium chloride pulls moisture from snow and ice and releases heat as it dissolves, so it works faster than rock salt or blended deicers, especially in deep cold. It is a good fit for driveways, walkways and steps where fast clearing matters and staining is a concern. Against cheaper rock salt it costs more per pound but needs less product and leaves no powdery white residue; the trade-off is that calcium chloride is harsh on lawns, plants and bare metal, and the pellets draw damp from the air in storage.
