Can't choose between sodium chloride, magnesium chloride, and calcium chloride? You're not alone. Every year, city workers, homeowners, and property managers struggle to find a safe and effective ice melt to use on roads, sidewalks, and driveways.
Let's talk about the most divisive ice melt of them all: magnesium chloride. You may have seen a few articles about this popular ice melter, claiming that it may be harmful to plants, pets, and concrete. Sure, every ice melter has its pros and cons; however, magnesium chloride has proven its worth time and time again.
Let's debunk some of the myths about magnesium chloride.
Myth: Magnesium chloride harms plants.
Fact: Funny enough, magnesium is one of the main ingredients in many fertilizers. If your plants are dying, it’s not likely that it's from magnesium chloride. The truth is that winter is just really rough on plants. Try to take extra care of them when snow and ice are on the ground.
If you're worried about your plants, try to keep flakes or pellets as far away from them as possible.
Myth: Magnesium chloride damages concrete.
Fact: Water from melted snow and ice will find its way into concrete. When that water re-freezes overnight, it expands and shifts the concrete, causing spalling and pitting.
Magnesium chloride is actually hygroscopic, which means it absorbs moisture.
While concrete spalling is a big concern when using ice melt, it's less likely to occur if you're using magnesium chloride.
Myth: Magnesium chloride is very toxic.
Fact: Magnesium chloride is significantly less toxic than sodium chloride and calcium chloride, so it is considered safer for the environment. Measured toxicity levels show that magnesium chloride is even less toxic than baking soda and table salt. That means less skin irritation, less metal corrosion and fewer problems for your pets. Take a look at this brochure for more insight. If you're searching for a safer ice melt, you can relax knowing that magnesium chloride can be used around your home without fear.
