Well,--They say that reduced temps reduce reaction times of chemical processes, but personally if it isn't too much trouble I would get the pressure-washer out and jet-wash that crud out of there...
The salt is the issue, and as I live right on the coast and the local council salt the roads here like nutters, I know the scenario well!
One dry day it would be worth waxoyling all the underside and wheel-arches, it does get washed off in time but at least it does help...
(As waxoyl is so expensive, I made up my own--I'll post the recipe if you want...)
You can pour waxoyl into the sills (rocker-panels) if you remove the outer rear seat-belt mount bolt, and pour a litre or two in there--Have car on slight hill to allow the stuff to flow forward. Temp. block the rubber sill-drain for a day or two.
If you want to do a fairly good job of it, pop off the door-panels and coat the internal structure of the doors too. Under the rear seat you'll find a number of rubber grommets that lead into the various chassis members--Give 'em a good old dose with a lance and modded plant sprayer....
