I had a very minor Mountain Dew spill several weeks ago, and I thought nothing would come of it. As time progresses, several keys are losing their effectiveness. Some sugar has to be in there gumming up the works. The keys that don't work the worst are "p", "'", shift and enter, right around my liquid spill. These keys have extra physical resistance, and once pressed, they send the right electrical signal, so I'm very optimistic that a Q-tip and a little alcohol will fix me right up. I don't see any screws on my A1243 thin aluminum keyboard that came stock with my 3GHz 24" Merom iMac. Does anyone here have experience taking them apart or cleaning them?
