OK, So my girlfriend's MB survived me spilling some beer on it, and is working great. except, several of the keys in the lower right are sticky: arrow keys, right side apple key, space bar, mouse button. What's a good option for cleaning underneath the keys? do they pop off like on a standard keyboard? Can I squirt small amounts of alcohol under them, work the key a few times, and wait for it to evaporate? The keys are working, just real slow on the release. should I just wait and hope it works itself out?
