Rock Salt is a great gritting salt! It is a natural substance made up of sodium and chlorine elements (sodium-chloride) and will easily de-ice most frozen surfaces, so you can enjoy the winter months with ease and avoid any dangerous falls. However, it is important to note that if the temperature falls below -8ºC, then rock salt may lose its effectiveness.
