Brown vs White Rock Salt: What’s the Difference?

When winter weather hits, keeping your premises safe and operational depends on using the right de-icing materials. At Bawcro Gritting, we specialise in gritting services across Yorkshire and one of the most common questions we get asked is: what’s the difference between brown and white rock salt? This guide breaks it down so you can make the right choice for your site.

What Is Brown Rock Salt?

Brown rock salt (also known as grit salt) is mined in the UK and contains natural impurities such as clay and sand. These impurities give it a coarse texture and its distinctive brown colour. However, it does leave a brown residue that can be walked indoors, potentially marking floors or carpets. For sites where cleanliness is a priority, this may be a drawback.

What Is White Rock Salt?

White rock salt is typically harvested through the evaporation of seawater and contains fewer impurities, giving it a cleaner and finer finish. It works just as effectively at melting snow and ice but is especially popular in environments where cleanliness matters. White salt is generally more expensive than brown salt and while it’s clean and efficient, it offers slightly less surface grip due to the lack of natural grit.
