Road salt

Chemicals used to de-ice surfaces

Road salt (also known as deicing salt, rock salt, snow salt or grit salt) is a salt used mainly as an anti-slip and deicing agent for roads, sidewalks and other transportation surfaces during the winter. The most commonly used form is sodium chloride (NaCl), though other salts such as calcium chloride and magnesium chloride are also employed, especially in colder temperatures. When used in its solid form, road salt is often pre-wet to accelerate the ice-melting process.
