Cleaning sticky keys?
A few months ago I spilled coffee on my macbook pro.I took it into to the Apple store and luckily no damage was done and the guy at the genius bar cleaned some of the keys for me.Everything worked fine until recently some of the keys have been a little sticky.Ive read that you're supposed to clean them with a little alcohol and a cotton swab...is this the best way to do this?If not what should I use to get rid of the stickiness?
Thanks
