homesick:
I'd leave your keyboard as it is - your post is intelligible, which is a damn sight more than other posts elsewhere on PPRuNe.
Seriously, as long as it wasn't anything corrosive, then once it dries out it will be fine. If it was something sticky like coffee or beer then a judicious soak in warm water, followed by a long rinse in fresh water, should work. If it's a bog standrd keyboard and you can't be bothered to do all that, then a new keyboard is in the offing - try wireless, brilliant !
