Liquid Ice Melt quickly penetrates and dissolves frost, snow and ice accumulations and prevents further build-up. It will not leave a residue on floors, and will not cause damage to or form residue on asphalt, concrete, terrazzo, aluminum, steel, plastic, rubber or painted surfaces. Use it on stairs, sidewalks, driveways, bridges, ramps and loading docks where ice and snow pose a safety hazard. It also prevents the freezing of locks, chains, hinges, linkages, controls, coal conveyors and equipment. Effective to -60° F.
