Ice melt ideal for de-icing driveways, sidewalks, steps, and parking lots. Made up of a mixture of sodium chloride blended with magnesium chloride for fast and effective ice melting. Melts ice down to -7 degrees Fahrenheit/-21 degrees Celsius. Melts ice in a shorter time than other chemicals. Will not harm trees, vegetation or pets when used as directed. Safer when used as directed on air-entrained, cold-weather concrete that is at least 1 year old. Leaves no powdery white residue to coat walks and steps. Corrosion inhibitors reduce potential damage to metal. Use 1 cup (10 ounces) of ice melt per square yard and spread evenly, avoiding piling or overspreading. Remove resulting slush. Reapply ice melt as needed.
