When winter storms bring historic levels of snow, freezing rain, and cold temperatures, one key step in preparing is to apply ice melt on your driveway and sidewalk. There are many options available, such as rock salt, magnesium chloride, and calcium chloride ice melts, but not all are ideal for concrete surfaces. To protect your concrete, you should avoid using rock salt whenever possible. However, when major storms hit and the ice melt supply is low, it is best to use whatever is available to avoid slippery surfaces.  

Why Ice Melt Can Damage Concrete

The main reasons people use ice melt during a snowstorm are to keep their driveways and sidewalks from freezing, make snow removal easier, and to keep driveways and sidewalks safe for cars and foot traffic. However, when snow melts, concrete absorbs more water due to its porosity, and when that water freezes, it can cause concrete to expand, leading to damage such as cracks, scaling, and concrete corrosion. Using the right ice melt for concrete can help prevent water from freezing for up to 24 to 72 hours, depending on the product. However, if your area experiences multiple freeze-thaw cycles, that can lead to concrete damage (this phenomenon is the leading cause of concrete damage, in fact), even if you’re using the right product for your concrete surfaces.

Best Ice Melt Products That Are Safe for Concrete

Choosing the best ice melt products for concrete comes down to the ingredients. Gene Caballero, co-founder of GreenPal, recommends looking for “products that use calcium acetate or magnesium chloride. They are gentler on concrete and landscaping than traditional rock salt.” Ice melts labeled “pet safe and landscaping friendly” are also good options for concrete.  

Safe Paw Ice Melt 

Safe Paw Ice Melt is a multi-purpose ice melt safe for use on cured concrete, pavers, bricks, driveways, lawns, and more. This ice melt is organic and non-toxic, providing up to 72 hours of protection. In addition, the product is safe for pets and children. It’s non-corrosive and provides long-lasting results, preventing snow from refreezing. However, it is one of the most expensive ice melts available. 

Caballero recommends using Safe Paw and any calcium magnesium acetate-based products and magnesium chloride blends. These are better options than pure sodium chloride products, he adds.

SnowJoe Premium Enviro Melt  

SnowJoe Premium Enviro Melt is a magnesium chloride- and calcium magnesium acetate-based ice melt works in cold temperatures of up to -10 degrees Fahrenheit (F). Although it does contain sodium chloride, the company states it is safe for concrete, vegetation, and metals when applied properly. The formula provides quick and fast results, starting the melting process as soon as it comes into contact with the snow. Plus, it enhances traction, and the calcium chloride crystals provide up to 24 hours of de-icing. According to the manufacturer, when applied correctly, you don’t have to worry about tracking it inside your home, as it won’t stick to your shoes. 

Fireki Ice Melt

Offering protection for your concrete and pets, Fireki Ice Melt is a magnesium chloride-based formula that works even when temperatures drop down to -35 degrees F. The product has no additives, coloring, or corrosive ingredients, making it a safe choice for decks and concrete, and it is pet- and child-friendly. The ice melt container comes with a scoop for easier application and distribution. It is recommended to apply the ice melt before snow starts falling for the best results. 

Organic Melt 

Conveniently packed in a shaker jug for easy application, Organic Melt isn’t only safe and effective for your concrete, but it is also eco- and pet-friendly. Containing sugar beet as the base ingredient, it’s a safe option for wood, decks, landscaping, and concrete. This eco ice melt works in temperatures as low as -30 degrees Celsius, making it a great option for areas with extreme freezing temperatures. Organic Melt is a good choice for homeowners with small walkways and sidewalks, as it is pricey. 

Harris Kind Melt 

With a magnesium chloride-based formula, Harris Kind Melt is safe to use on concrete and at home with your four-legged friends, as it won’t burn their paws. This de-icer works well in temperatures as low as -13 degrees F. The active ingredients of Harris Kind Melt are less corrosive than traditional rock salt. This product is fast-acting and lasting. However, like any chloride-based product, it is important not to overuse it. 

MAG Ice Melting Pellets

Offering protection for your concrete and pets, this magnesium chloride-based ice-melting product is a good option to have on hand during snowstorms. PURE MAG Ice Melting Pellets are environmentally friendly, work in temperatures as low as -15 F, and are fast-acting. You can use this product on concrete, on asphalt, near lawns, and around pets. 

What to Look for in an Ice Melt That Is Safe for Concrete

For starters, avoid using rock salt, anything containing salt, or anything labeled as sodium chloride on your concrete when possible. The safest ice melt for concrete will be made of calcium chloride, magnesium chloride, or calcium magnesium acetate. 

Aaron Strickland, owner of Mr. Trim Lawn & Garden Services, recommends his clients stay away from rock salt and use “calcium or magnesium chloride, which are less likely to damage concrete surfaces when applied properly.” It is also important to know how much to apply and when to apply these products. 

“Over-application is one of the biggest mistakes I see; too much product can pull moisture into the concrete and lead to scaling and surface damage over time. My advice is to remove snow early and often, use ice-melters only when absolutely needed, and rely on traction materials when necessary,” Strickland explains.
