Snow!

mate, you haven't got sufficient knowledge about grit salt on the road as you are british :{)
i'm from a cold country where gritted roads are everyday's (late autumn, winter and early spring) cruel reality... i'm not suggesting that you should jetwash it with boiling water - pour gently so the salt disolves before it reaches crucial ares:) repeat it twice or three times

and don't try and tell me you have an A from chemistry :{)

PS: anyway, how are you doing mate? going to w drinks tonight?:{)

haha, I am not British but nevermind.

I'm all good my friend, and I hope to see you this evening!
