Excess salt has been found to create an environmental hazard for the flora it comes in contact with, killing and ruining landscapes. Ice Ban is an environmentally safe and approved additive in our salt mixture to make melting of the snow more effective as well as eco-friendly. Ice Ban is a liquid agent that, when added to snow, creates a level of acidity that is similar to that of distilled water. This results in a chemical composition that is much safer to the plant life that soaks up the melted snow than the excess salt that using rock salt alone creates.
