The use of magnesium chloride, also sometimes referred to as MAG, to melt the ice on concrete sidewalks, driveways or roads can be deadly. Why take the risk? MAG was once thought to be a safe and powerful ice melting solution. However, today there is much scientific information and evidence on the concrete damaging effects of magnesium chloride. There are ice melt products on the market today, like XYNYTH Manufacturing''s Mountain Organic Natural Icemelter or GroundWorks Natural Icemelter, which an end user can safely use on their concrete with no damaging side effects.
