we are surrounded by the sea, the sea is very salty.
so why can’t we just spray loads of saltwater on the snow and ice.
the bulk of the snow and ice will be washed away, but i’m sure some of the seawater will freeze, but surely only a very thin crispy layer.
i don’t think we will run out somehow.

i think i would do more damage 
Last winter, Detroit. MIchigan, city council apparantly thought they’d save a few $ by buying some cheap salt to put on the roads in certain areas of the city.
There’s an old saying that says something along the lines of what’s cheap is dear. Certainly true in this case.
You should see the state of the roads & massive pot holes. They gotta rip 'em & all up & re tarmac it all.
Also ofcourse, if its cold enough, the sea freezes. Maybe not in sunny Blackpool Phil, but take the Baring straits for example.
Anyway, don’t the latest generation of gritters mix saline solution with the grit? … and isn’t that exactly why there’s so much ice on the roads this year?
This is something that i’ve thought about during this cold spell, why don’t they mix the Salt with water and spray the roads with that…I was on holiday over xmas in a canal boat and we went up to the Nantwich area and we went past a salt factory and the canal next to the factory was the only bit not frozen…

If that was the only bit not frozen, how did you get there??

left the barge and went by train
I served on HMS Invincible for a while in my short Navy career, one evening in the North Sea, the flight deck officer had the inspired idea of spraying the entire flight deck with sea water, to prevent it freezing in the sub zero temps.
He was not popular the following morning when every inch of the deck had to be chipped free of ice with a shovel, before flying operations could commence. Evidently, salt water freezes as well as anything else.

10 out of 10 for observation Woody 
What they actually need is a desalenation unti to remove the salt and also give clean drinking water it would work well for the South as they are usually first without water when theres a shortage but theres one problem with it…
It costs money and after the mp’s have had their expenses and wages theres not much left

As ice begins to freeze out of the salt water, the fraction of water in the solution becomes even lower, and the freezing point drops further! However, this doesn’t continue indefinitely. At some point the solution will become saturated with salt. This happens for salt in water at -21.1°C, which therefore is the coldest a saturated solution of salt and water can get.
At that temperature, the salt begins to crystallize out of solution, along with the ice, until the solution completely freezes. The frozen solution is a mixture of separate salt (NaCl·2H2O) crystals and ice crystals. This heterogeneous mixture is called a eutectic mixture.
There ain’t half some bollox talked on here!

so it could be done then? after all the average sub zero temperature in england was only about -3c.
I think theres different grades of salt and where rock salt is effective at treating roads, salt seperated from sea water or common food salt might not be, I may be wrong, if professor 44 would like to ellaborate. 
Here is some we prepared earlier, now where is that toilet roll holder and a washing up liquid bottle
Salt in water, makes for faster boiling too

I believe the problem the councils have nowadays is that a few years ago they switched to a smaller grit size due to complaints of damage to paintwork on cars when gritting the roads. The unfortunate side effect of this is that the salt is flushed away much more quickly so as soon as the salt levels drop the road surface can freeze again when temperatures are below 0. Any salt will do the job of melting ice. I’m guessing that the problem with sea water is that the salt will rapidly flush away because of the small particle size leaving a lot of water behind which would quickly turn into an ice rink!

Hmmm, interesting. Any idea on this then 44TT? Shifted the snow from the back door step & some of the paths around my house. Sprinkled Morrison’s table salt. Job’s a good’un. No ice.
Snows again & i do the same again. This time it remains below 0* all day. Having used up the salt i had last time, i now use a new lot, exactly the same stuff from Morrisons. Result: Nada, zilch, zero. Back door step & paths like an ice rink. 
Your neighbours who didn’t have any salt cos somebody bought Morrisons entire stock came round at night and ■■■■■■ on your doorstep!

750 grams, they seem to have more than one on the shelf at the time.

So you can’t explain it then obviously.
