The Polar Vortex that has gripped much of the country this winter has meant using every means necessary to keep snow and ice from building up on our driveways and sidewalks. While many of us reach for salt as a deicer, there are many reasons to avoid it as much as possible: Salt can be detrimental to plants, burn the paws of dogs that walk on it and heavy metals in it can leach into waterways. But when all you can find is salt to make your morning commute easier, do this one thing: choose wisely. Look at the packaging and choose deicing salt made from calcium chloride, not sodium chloride. Calcium chloride actually has a more efficient and effective composition than sodium chloride. You can reduce the environmental damage and still get the same results with less salt.
