ACTIVE INGREDIENT: UREA , POTASSIUM ACETATE & CORROSION INHIBITORS
Run-Way is made of the same material as airport runways. As a pretreatment, apply it up to 12 hours before the ice forms to create a chemical barrier that completely protects against black ice. Because it is frost-activated, it remains dormant until it comes into contact with snow and ice. It melts quickly on sidewalks, stairs, valves, fire escapes, handicapped ramps, and anywhere else. It works down to 60 degrees below zero. It is completely non-corrosive to concrete and metal. Run-Way never leaves that white residue behind, so it will not stain your floors or carpets.
