Mac is slower and has strange nuances in operation after liquid contact
I really think your best option is to take it into an Apple-licensed fix-it person and have them open it up. I expect they'll find some kind of damage on the motherboard (probably up and around the underside &amp; top). Water does some gnarly things to electronics, so just because it's still turning on and 'working' doesn't mean there isn't something damaged on the mobo.
