Does salt on roads really harm our cars?
Discussion
Not a scientist but seen the affects on a set of what were polished alloy wheels end result alloys so badly pitted had to be replaced.I sold my pride and joy to a lad in our village was offered it back a year later after hard use through all weathers,declined offer.Pride and joy at the time FZR1000 RU.
Hense i dont use my car in the wet now,even if the road is dry there still a layer of salt,the roads are giving that white colour once dried.I have polished my wheels and want them to stay in that condition.
When you have taken your car out and it has dried off you can see a film of salt,alloy gives of a white oxidation.

Exposure to any moist environment will cause any steel to rust eventually.
If you really don't want rusting, keeping the temp around 20C and the humidity below 10% will help, hence the reason cars in California and South Africa seem to last longer!!
Also clean off all types of surface contaminants such as salt, chlorine and even acidic substances which could even be finger prints ( Now that is scarey - don't touch my car or you'll make it corrode !!!).
So the combination of salt, moisture and the temperatures we get in the UK, don't help.
Not really sure if I've helped either !!!!

Been caught out a few times recently and wondered if I am worrying unduly....any scientists out there?!
i certainly know the ruddy great big lumps of salt rock they use do my windscreen harm - yet again this winter i need a new windscreen, courtesy of the bloody gritters and the lumps of rock they discharge onto the road.
anyone know why we have never adopted the synthetic stuff as used by most of europe?

The rock salt used on the road comes from a mineral called Potash, Potash is used for a vast number of things including rock salt.It is very corrosive and abrasive so the answer is yes it will corrode any metal including stainless. Best protection is rubber or epoxy 2 pack paints.
Rock Salt contains sodium chloride
Potash is Potassium Hydroxide
Different beasts!

Sure thats not Pishash.

Agree but potash is equally corrosive and attacks the metalwork on cars exposed to it.
It is used in fertilisers, amongst other things and will very quickly affect the chromeworks on cars too!
My new car has just arrived. So, just for information, where on the road is my car at risk from this Potash fertiliser corrosion?
It's not an off road vehicle.
Your's isn't.
We used to blend potash and rock phosphate on our Widnes site to produce a range of fertilisers.
You simply won't come across it generally in any significant quantity.
The dust used to attack the chrome on our car bumpers (when they were chrome) and much of the machinery in the works.
