The problem with road salt…

October 3rd, 2011

Road salt accelerates metal corrosion processes, which is bad news for cars.

…is that it accelerates metal corrosion processes, which is bad news for cars. Add in the wider environmental damage it causes, particularly to waterways and man-made structures, and it becomes clear that its widespread use as a road de-icer during the winter months is controversial to say the least. Last autumn, we posted an article about road salt and the need for car care enthusiasts to protect their cars against it. Despite the unusually good weather we are currently experiencing, it won’t be long now until the nights draw in, temperatures drop and the gritting lorries make an appearance. With this in mind, we thought it would be useful to revive last year’s article and refresh your memory about the importance of proper winter preparation. So, without further ado…

  1. Road salt is one of the worst things for your car during winter – but one of the best for roads. A necessary evil!

  2. Thankfully it hasn’t reared it’s ugly head yet this year (at least in my area). Will be keeping my fingers crossed for a salt free winter 😉

  3. I wish I could report the same for the area around PB HQ – the roads are thick with salt and grime right now. Yuck!

    Road salt is not a necessary evil anymore! ecotraction = instant grip but no corrosion. Also good for plants and non toxic to animals. It’s here in the UK and on sale and it works. Gives traction rather than focusing on melting ice, until you walk on it for yourself you wont believe it.

  5. Interesting information, thank you – I’ve just looked up the UK website and it seems promising. From a car enthusiast’s point of view, my only concern would be the impact of more fine grained debris on the road in terms of causing paint damage (like the type they get in sandy areas of the world) but other than that it certainly seems a lot wiser than using road salt.

    Hi, well the product is natural and the granules embed into the ice and snow, so paint damage should not be too much of a problem, plus you need 9x less than you would do road salt – we do sell to both trade and public. Imagine how much the public purse could save if they made the switch; the NHS is apparently the UK’s largest user of road salt!

  7. With regard to paint damage, I was thinking more about what happens when all of the snow and ice has thawed. Then, as it often the case with road salt, we are left with lots of loose granules on the surface, which get thrown up onto our cars along with other road debris. However, if 9x less product needs to be scattered in the first place, then maybe this won’t be a significant problem. It’s certainly got merit compared to road salt, so all the best with promoting the product – fingers crossed you can convince the powers that be!
