Premium Quality Brown Deicing Grit Salt for Snow and Ice Frost Melt A 20KG bag of premium brown rock salt. Ideal for roads, path and driveways, it keeps surfaces clear of snow and ice. The rock salt helps to keep areas accessible and safe, which is especially important in working environments and public areas. Brown rock salt is more cost effective than white, making it ideal for larger areas or places that are more likely to be affected by ice or snow. The salt works quickly to remove ice and snow to create a safe path for both foot and vehicle traffic. It also contains grit to provide extra traction on surfaces, further reducing the chances of slips occurring.
