Are the chemicals used corrosive or harmful to the environment?

Common salt is recognized as the top material with regards to performance and cost, and it is more widely used across the world than any other chemical.  Salt is not as harmful to the environment as many other chemicals, but it is corrosive. Mixing salt and water to create salt brine minimizes the environmental impact of salt by 80%.

Other liquid de-icing agents used at low temperatures are biodegradable products with reduced corrosive qualities.
