This Rock Salt is a fast acting and easily spreadable. It is formed when sea water is evaporated on the salt plains, which leaves thousands of tonnes of raw white sand behind. This salt is then washed, graded to the correct size and finally an anti-caking additive is added to prevent clumping up.
Rock Salt is recommended for use on paths, driveways, footpaths, roads and motorways, as well as in schools, supermarkets and business parks. The main advantage of white rock salt is that it leaves very little residue behind compared to brown rock salt (which leaves a little). For organisations where cleanliness is an issue, or locations where a lot of people are walking salt inside, then this White Rock Salt can be a useful alternative to brown.
Sold in 20kg bags, Rock Salt is also available in bulk bags
Rock salt has a long shelf life and, if kept covered or kept in bags away from prolonged direct sunlight, then storage will be fine for the next few years.
