hmm gonna be difficult i think.
first thing i would do is remove the keyboard, easier said than done sometimes, but generally helps if you download the service manual. there is usually individual sections detailing how to remove specific parts. they dont make it too difficult because to access any of the motherboard you have to take the keyboard off anyway.
sometimes the keyboard is attached with a screw or 2 from the underside, and depending on brand, there is a keyboard symbol next to the hole
come to think of it....... do you have a mack?? that looks pretty easy and plenty guides on the net, just be careful of the ribbon cables, they can break quite easily.
then get your qtips out and poke about best you can on the stuck keys.
other than that, becasue they are so fiddly and a pain to reattach keys if you take 'em off, it's best just to buy a replacement k/b :/
i think in theory you could leave it in a bowl of water
but i'd let it dry for a week before plugging it back in hehehe
