Keys are sticking from a liquid spill...help?

I have a mid 2012 MacBook Pro. My keys are sticking now due to a spill of wine right on my keyboard. Luckily, the computer seems fine, but almost all of the keys are sticking like crazy. I tried to take them off and clean as well as I could with alcohol. I'm just scared to break anything. Suggestions? Thanks! I appreciate the help.
