As winter approaches and the temperature starts to drop, the roads, pavements, and driveways will become treacherous. To keep these surfaces clear of snow and ice, many people turn to rock salt. But did you know that there are different types of rock salt? Below, we'll explore the differences between brown rock salt and white rock salt and which one you should choose for different applications. (We stock Winter Products which can be found here).

Brown rock salt:

Brown rock salt, also known as grit salt or roadway salt, is the most common type of rock salt used in the UK. It is mined from rock salt deposits and then screened to remove any impurities. Brown rock salt contains a mixture of sodium chloride and other minerals such as calcium, magnesium, and potassium, which give it its characteristic brown colour.

One of the main benefits of brown rock salt is that it is effective at melting snow and ice quickly, even at low temperatures. It is also relatively inexpensive compared to other de-icing products, making it a popular choice for local authorities and businesses.

White rock salt:

White rock salt, also known as pure rock salt or marine salt, is a purer form of rock salt than brown rock salt. It is made by evaporating seawater or brine to produce pure sodium chloride crystals. White rock salt is usually more expensive than brown rock salt due to the extra processing required to produce it.

The main benefit of white rock salt is that it is more environmentally friendly than brown rock salt. It contains fewer impurities, which means that it produces less residue and is less damaging to plants and wildlife. It is also less corrosive to metal surfaces, making it a good choice for areas where metal corrosion is a concern.

Which one should you choose?

The choice between brown rock salt and white rock salt ultimately depends on your specific needs and budget. Here are some guidelines to help you make a decision:

• If you need a cost-effective de-icing product that can melt snow and ice quickly, brown rock salt is a good choice. It is suitable for use on roads, pavements, and driveways, and is effective at temperatures as low as -9°C.

• If you are concerned about the environmental impact of de-icing products, or if you need a product that is less corrosive to metal surfaces, white rock salt is a good choice. It is suitable for use on sensitive surfaces such as concrete, brick, and metal, and is effective at temperatures as low as -7°C.

• If you need a de-icing product that is both cost-effective and environmentally friendly, you may want to consider a mixture of brown and white rock salt. This will give you the benefits of both types of salt while reducing their respective drawbacks.

In conclusion, both brown rock salt and white rock salt have their own unique advantages and disadvantages. By understanding these differences and choosing the right product for your specific needs, you can keep your surfaces clear of snow and ice and stay safe during the winter months.
