Tacky Keyboard from Spill as well!
I had a tea spillage of Tea (with sugar and milk) a couple weeks ago on my new macbook. After airing it out for a number of days, the damage is a crazy ugly stain on the LCD screen and a tacky keyboard, but luckily nothing too serious.
I have already decided to get the LCD screen replaced by a certified Mac Technician, and I have refused to go into Apple to tell them about the spill. If I send in the computer, I can get the LCD screen replaced for around 200 bucks.
In terms of dealing with the tacky keys, I have tried everything. Air compressor....I have also removed the battery and power cord, and slipped a little water under each key with a sterile sponge and let it dry overnight to try and get the goop out. I do not think it's a good idea to take off the individual keys. It does look complicated and I fear not being able to put them back -- I don't think I'd have the patience.
However, what about taking off the top case? From what I see, that looks like a fairly easy procedure.

What I don't know is: After removing the top case, do I actually clean the keyboard or do I have to deal with the mechanisms underneath? Is this actually worth doing or would I not be able to clean the keys anyway? I would assume others who are suffering from a tacky keyboard or trackpad would appreciate knowing. Thanks!
