No, there is a variety of rock salts that you can purchase for snow removal, and they differ from rock salt used for culinary purposes. For example, we carry ice control salt, which is a coarse screened sodium chloride salt. We also have Ice Breaker salt, a blend of sodium chloride, calcium chloride, potassium chloride, and magnesium chloride. We also have treated bulk rock salt available, which contains additives and a dye.
