It pays to know the difference and benefits that Brown Rock Salt and White De-Icing Salt have and what they have to offer, so you can find the one that is the best for you.

They work in very similar ways and achieve the same goal, allowing us to use them through the winter, to melt the ice and keep our roads and pathways clear, keeping us safe! However, there are a few things to consider, including the benefits that each salt brings. Hopefully this information can help you decide which salt works for you.


Rock Salt is the salt that most people refer to when they mention grit salt or road salt. Brown Salt is nearly always used on the roads, being spread by gritting machines throughout the winter.  

The Important Stuff

Rock Salt comes under different names, the main one being Halite. You might have found this when you were searching for Rock Salt for Sale. We actually source Brown Rock Salt in the United Kingdom unlike White De-Icing Salt. Rock Salt is mined in a few places over the country, in salt mines. Following on from mining the Rock Salt, it goes through less processing than you might think! Consisting of Sand, Dirt, Sodium Chloride, etc. The build up of Rock Salt, makes it great for increasing traction on slippery roads as well as de-icing. The only caveat with Brown Rock Salt, is that it leaves a muddy sludge behind, which can be trodden into carpets and such. For this reason, it's mainly used a residential grit, clearing the pavements, making it safer for all of us to walk on. With this being said, let's discuss the pros and cons to using Brown Rock Salt.

White De-icing Salt is sourced from several countries and is considered cleaner than Brown Rock Salt, as it is sourced by evaporating sea water, rather than mining it. 

The Important Stuff

White Rock Salt is sourced from countries with much hotter weather than we are blessed with. Perfect examples of these are Spain and Egypt.These countries have fantastic climates that provide us with White De-Icing Salt with a high concentration, that doesn't contain a whole variety of materials like Brown Rock Salt. As this is the case, you get more genuine salt and it also has a greater aesthetic appeal and leaves virtually no residue!With this being said, let's discuss the pros and cons to using White Salt.


Readily Available - Although not sourced within the country, we have taken extra steps this year to make sure we have the stock ready for dispatch! 

Cleaner - With Salt being the near standalone material, in White Salt, there won't be any brown residue left behind, unlike with other rock salts.

Where does Rock Salt come from?

Rock Salt comes under several different names, but, the main distinction is that, de-icing rock salt is a rock, rather than a mineral, showcasing the difference between rock salt and the salt you have in your kitchen! Rock Salt can be found all over the world. It is typically formed by evaporation of salty water like seawater. Salt normally forms in deposits ringing dry lakebeds, inland marginal seas and in enclosed bays and estuaries' in arid regions of the world. In times gone by, very large areas of water evaporated and makde large amounts of rock salt. Marine sediments would then bury the salt. Halite is less dense than the marine sediments so it would push its way up through the sediments creating a dome like structure. 

About Our Brown Rock Salt

The Rock Salt we supply is mined in the UK and graded to BS3247:2011 (Highways Agency Standards), which means it is crusged and screened to contain granuals between 1mm and 6mm in size. It contains an anti caking agent to prevent the salt from forming lumps, this ensure it is free flowing and is therefore suitable for use in grit spreaders.Our Full Specification & Rock Salt Material Data Sheet is available on online Brown Rock Salt has a dry density of approx 1.28 tonnes per m3 or 1.44 tonnes per m3 when wet.Highways Spreading Rates for Rock Salt:These figures are at best a guide for use on highways with properly calibrated spreaders: 

Dry road frost or ice 10-15 grams per m2

Wet road frost or ice 20-40 grams per m2

Snow on roads 40-60 grams per m2

Spreading rates using pedestrian spreaders will be significantly higher.

Winter Tyres & Snow Chains

We’ve discussed winter driving, and touched on snow chains and winter tyres, so we thought it might be helpful to provide a bit more information about both.

Winter tyres

Winter tyres are made of a special compound with a high silica content, and have a tread pattern which means they are more flexible at lower temperatures and will brake better on ice than summer tyres. Their overall performance is not as good as summer tyres, so they’re not a year-round option, but if you live in an area that has a lot of snow and ice, they’re a good choice for winter.
