I ride all winter commuting in Montreal, a very wintery and very salty city ;-)
Im always surprised how even at -10 or -15c, there still can be a liquid salt brine on the road that gets all over the bike, and so I always wash my bike when getting home.

I'm lucky as I have a garage, so a place to do this and not worry about a bit of a mess.

Nothing fancy, a real fast wash of the entire bike with soap and water using a big soft bristled part of a floor broom, spokes and rims included, chainrings. I then wipe the chain with a rag and just spray some WD40 on it.
It aint the best lubricant, but for the distances I do its perfectly fine and super fast to do (5 seconds or less maybe pedaling backwards and spraying) and I figure the WD water displacement thing is good for the chain, given the salt brine stuff that gets thrown onto it.

very different scenario of all this back and forth, but it works for me in a real disgusting salty environment.
Works for the bike too as the old bike stays in pretty good shape.
(but I do grease up all kinds of bits and bobs on the bike each season to keep corrosion down)
