Choosing Ice Melt: What's Safe for Concrete, Plants and Pets

The main types of ice melt

Each product works down to a different temperature and has different side effects.

• Rock salt (sodium chloride): cheapest, effective down to around 15°F, harder on plants and new concrete.
• Calcium chloride: works in deep cold and melts fast; use the recommended amount to avoid residue.
• Magnesium chloride: works in cold weather and is generally gentler on surfaces and vegetation.
• Pet-friendly blends: formulated to be gentler on paws; still wipe paws after walks.

Protecting your concrete

Most damage comes from the freeze-thaw cycle, not just the chemical. Concrete poured within the last year is the most vulnerable, so check the product label before using any de-icer on it.

Shovel first and apply ice melt only to the thin layer that remains. Using less product works better and costs less.

Apply it evenly

A handheld or walk-behind spreader spreads granules evenly so you don't overdose one patch and miss another. Apply before a storm to stop ice from bonding to the surface.
