Ice-Melt & Snow-Removal Supplies

Plain rock salt (sodium chloride) is the cheapest and works down to roughly 15–20°F, losing effectiveness fast below that. Calcium chloride works far colder, gives off heat as it dissolves and acts quickly. Magnesium chloride and CMA blends are milder and are what most pet-safe products are built from. On concrete, the real damage is usually not chemical but physical (the ice-melt guide works through it): melt water soaks into the slab, refreezes and spalls the surface. Concrete poured within the last year is most at risk, and so is anything that was not air-entrained or properly cured. Shovel first, use the least product that does the job, and clear the slush rather than leaving it to refreeze.

Less than most people spread. A thin, even scatter is what works — ice melt is there to break the bond between ice and pavement so you can lift it, not to melt a storm away. Piling it on wastes product, tracks indoors, and puts more chloride into the soil at the edges of the walk. Spreading before a storm, so ice cannot bond in the first place, uses far less than trying to burn through afterwards.

It is a long-handled blade for pulling snow off the lower few feet of a roof from the ground. The point is ice dams: heat escaping through the roof melts snow higher up, the water runs down to the cold overhang, refreezes, and the ridge that forms backs water up under the shingles. Clearing the bottom edge removes the snow that feeds the dam. Work from the ground, mind overhead lines, and never get on an icy roof.
