Brown & White De-icing Salt - Whats the Difference
Brown Rock Salt and White Rock Salt both do exactly the same job, they both prevent ice forming and melt snow and ice on paths, drives and roads. Both products perform equally well and work in exactly the same way.
Brown Rock Salt (aka Grit Salt or Rock Salt, Halite ) is mined from huge ancient seams of rock salt, these seams have been formed from old ancient sea beds that have dried up and become locked into rocky seams. Most of the brown rock salt used in the UK is mined here in the UK in the huge deposits deep under Cheshire.
Benefits of Brown Rock Salt
- Usually Drier than white salt & therefore flows / spreads more easily
- Cheaper than White Salt
- It is a British Mined Product
- Much smaller Carbon foot print than White Salt
White Rock Salt is made from evaporated sea water, salt pans or salt beds are flooded and then left in the heat of the sun to evaporate the water leaving a salty deposit behind, this process is repeated until the salt deposit is big enough to harvest. All the white de-icing salt in the UK is imported from countries such as Spain, Italy and Egypt where the temperature is high enough to make this process viable.
Benefits of White De-icing Salt
- Cleaner Product - does not leave brown residue behind that rock salt can.
- Aesthetically more pleasing
- Can be more readily available in times when rock salt supplies are restricted.
Which Product Do We Recommend?

Use White de-icing Salt in areas where there is alot of human foot traffic going into buildings with carpets that may be stained by the brown residue left by brown rock salt.
