Garden Hubs brown rock salt also is known as grit salt is mined here in the UK from subterranean salt mines, crushed and then graded to create a 0-7mm grain range, which makes the salt ideal to use with spreaders on roads, paths, driveways etc as well as great for hand application. We always recommend that you wear gloves when applying by hand.
Our Brown Rock Salt melts snow and ice fast and prevents surfaces from freezing and becoming a slippery frozen hazard. The elements of grit aid traction on paths. It also prevents ice from forming on paths, patios, driveways, roads and car parks, especially when applied before a freeze or snowfall.
