Ice melt is ready to use to help protect you from slippery walks, stairs, driveways and parking areas. When used as directed, the fast-acting de-icer will not harm carpets and plants and is safe for cement, concrete, asphalt and flagstone. Spread the pellets over the icy surface to dissolve snow and ice in temperatures as cold as zero degrees Fahrenheit. When used as directed, it leaves no powdery residue, resists refreezing and does not track indoors.
