Once you have the screen off, take the PCB out and submerge it in totally clear water. If there's corrosion go at it with a toothbrush. Leave it it more fresh water (in case there's still salt under some chips) then leave it to dry somewhere warm for a few days...
And maybe that'll fix it - if there's no serious corrosion visible then I think you have a pretty good chance.

Argh, sorry to hear that. After 2 weeks you'd have hoped it would have dried out a bit, and if it still doesn't work it's not great news.
But in a way you don't have much to lose and there is a reasonable chance it could be recovered. There's a post here where someone gives instructions for dismantling their Bangle 2: http://forum.espruino.com/conversations/373434/#comment16672619
