Mpx200 Help!

Hey guys i recently dropped my Mpx200 smartphone in a glass of milk.....I instantly took the battery out and washed it all out with water, its been about 4 days since its happened. I popped the battery in today and it powered right up, BUT the main button i need, the one that accesses the start menu doesn't work.....any suggestions, I can't even figure out how to take the thing apart, I took all 4 screws out from behind the battery cover but it seems to not want to come apart......thanks for any help you can give me

EDIT : to help out a little the key that isn't working is the left softkey

What about re-creating the crime with a glass of water this time? As long as there is zero electricity going to the circuitboard its surely washable. Replace the battery and power up the phone only after you are completely sure its dry.

Note: I pull my knowledge only from others washing their computer parts.. I've neither done this myself, nor tried it on a phone.

yeah i though about that but when it happened i took it apart as much as i could and ran it under the faucet for a few minutes....just wondering if moisture could have gotten into the curcuit board, and if so will the button start working once its gone?
