Sticky Keys... Literally

I recently spilled some apple cider on my keyboard, and now a few of my keys are really sticky - as in when you push it down, they take a while to rise back up. Particularly my shift key.
I have managed to remove the control, alt, etc. keys and fix those, but the shift key doesn't seem to come up. From what I can see, I'm pretty sure there is a metal bar under the shift key, so it's a lot harder to get up. Does anyone know how?
