Besides the tone of everyone's comments...
I hate to be the one to tell you, but this thing is toast...as is the case will all electronic devices, once they get wet, they develop corrosion, no matter how you shake them, let them dry, pull the battery, ect...
Corrosion is like rust on a car, once it starts you either replace the parts, which in your case would be the LB, and most likely everything connected to it...because it will spread and it may work for a while and then crash, or it may never work again, it varies, but in the end it will crash...if you have home insurance, get a replacement, Apple will not help with this, they will tell you that it was "abuse" and will offer to replace the parts that need to be replaced, and it will still be cheaper to get a new one, or a refurb.
Sorry, for the bad news, and good luck!
