A couple days ago I accidentally spilled lemonade all over my room. I didn't think I had gotten any on my keyboard, but apparently I did, as some of my keys are now sticky and really hard to press. Is there any way that I can 'unstick' these myself, or do I have to take it to my nearest tech store? (fyi my keys are most sticky under the keyboard and not on top of them). The computer is a 2010 MacBook Pro. Also, is there a way to clean the surface of your keys? I'm not too thrilled about the way they look right now and I would like to try and get them back to what they looked like when I bought it.
