De-icing products are substances used to remove or prevent the formation of ice on surfaces, particularly roads, sidewalks, and vehicles. Common types include rock salt, calcium chloride, and magnesium chloride. These materials work by lowering the freezing point of water, making it easier to melt ice and snow. These products are essential for winter safety, helping to improve traction and reduce accidents. They are often spread before or during snowfall to keep surfaces clear. However, it's important to use them responsibly, as excessive use can harm the environment and infrastructure.
