Steer clear of rock salt (sodium chloride) and urea-based de-icers. Not only can they pollute habitats with plant-killing runoff, but they can also corrode concrete, destroy your lawn (even a snow-covered one), and contaminate water supplies. Better bets? Sand, which provides traction without damaging salt-sensitive landscapes, and calcium chloride, which may still hurt vegetation, but is free of the cyanide present in rock salt.

Use Better De-icers
