Red salt is properly known as rock salt. Our pinkish brown rock salt is ideal for both small and large areas. It is mined as it comes, apart form the addition of some harmless anti-caking agent which means it stores well and can be used immediately. When the salt dissolves some minerals are left as residue which is why it is particularly suited to large areas like roads and car parks. As it is visible, you know exactly which areas you have spread the rock salt. Amazingly effective at de-icing and melting snow, it provides a great, cost effective alternative to white salt when spreading larger areas or if there is sustained cold periods.
