Product Description
PRESTONE Driveway Heat Calcium Chloride. Nothing de-ices driveways, walkways, and steps faster or at lower temperatures. Driveway Heat is a concentrate, not a blend of ineffective de-icers. Don't be fooled by imitators.....Driveway Heat ice melter is the concentrated real thing. HOW IT WORKS: Driveway Heat ice melter produces an exothermic reaction as it works, giving off heat. The heat enables the product to work down to negative 25 degrees Fahrenheit. Other ice melters lose effectiveness at 20 degrees Fahrenheit.
