What Is Driveway Salt?

Most ice melts are blends of the same ingredients: sodium chloride with calcium chloride or magnesium chloride.

How Does Salt Work?

The freezing point of water is 32 degrees Fahrenheit.

How Much Driveway Salt Should You Use?

Less is more when it comes to ice melt.

Spread it in a thin, even layer using a cup or a garden spade.

Itsnot the best product for vegetationlike your lawn and bushes, he warns.

Also if used too often, you might damage the surfaces over time.

Calcium Chloride

Calcium chloride is also very effective and, according to Manfredini, plant friendlier.

He advises not to over apply.

Instead, use just a thin layer of pellets to treat the surface.

Magnesium Chloride

Calcium chlorideis the safest option for both plants and pets, per Manfredini.

Plus, its effective below 15 degrees Fahrenheit.
