Anything used to melt ice is considered a deicer or ice melter, regardless of its material composition or the format it comes in. These products can appear in a variety of solid forms such as granular, flakes, pellets, pearls, or powder.

Ice melters work by lowering the freezing point of water, allowing ice to melt even when the temperature is below freezing. As the ice melter begins to take effect, a thin layer of brine forms on the surface of the ice. The ice melter dissolves into this liquid, which continues to break down the ice by disrupting its molecular structure. This process helps turn the ice into smaller pieces and eventually into liquid, making it easier to remove.
