keyboard cleaning options
At this point, I think you have two options. Green tea sounds like a "sticky" situation. (dont mind my puns.) I would try a can of compressed air or whatever, you can buy it at any staples, office store, or best buy sort of place. This probably wont work is my guess, but its worth a try. It wont cost you more than 7 or so bucks. The other option is to take it down to your nearest apple store, which i know often isnt so near, because mine is forty minutes away. Make an appointment with a mac genius ahead of time, you can do this on the apple website. Or you can just call the store and have them make the appointment for you. Talk to the genius and see what they say, they will probably be able to do something about it. I doubt you will be able to remove the keys safely, but if you want to try, stick a fingernail under the grey peice that covers the entire inner part of the laptop,pop that off and you may be able to access the keys. I would not recommend doing that until you have tried the air and the genius. Ask the genius if its possible to take off that peice.
