For de-icing driveways, sidewalks, steps, and parking lots. 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.
