So, on valentine's day a friend of mine managed to spill about a half a can of pepsi into my keyboard. I did all the right things after a spill (hah ) I immediately took out the battery, dried it off, opened the case up as far as I could and (this is sad) poured out all of the soda that was in it. I then propped it up in a V-shape against the wall for 4 days. When I took it into the Apple store, they checked my hard drive and I didn't loose any data. They said surprisingly that the only soda residue left was on the optical drive. BUT because it is a liquid damage, they won't even clean it for me because they consider it a tier 4 repair. 1240$ is a lot of money to have them clean it. Which leads me to my question. What is the best product to clean it with? I have something called "contact cleaner" which seems like it will work and says it is safe on components, optical fibers and a slew of other things. But is alcohol better? BTW the friend that spilled the soda said he'd pay for it to either get fixed or be replaced.
