Cleaning coffee/splenda corrosion from inside of MacBook Pro

So I spilt a whole cup of coffee in my macbook pro. I took the necessary steps, turned it off, took the battery out, took it back into the warehouse that I work at with a coworker and got out as much liquid as possible and left it to dry. When I turned it on, everything booted and so far the only casualties that have been were the superdrive, LED lighting in the back of the keyboard and now the fans are starting to get a little noisy. Right after this happened I took it to Apple and asked them if I should clean it since it still works and am not going to pay 1300+ to get it repaired. He advised against it and so did my coworker (He thinks if I leave it be, it'll be fine. Uh, yeah, no.) He said the logic board looked good, and to use the computer until it basically dies and then get a new one. But I want to extend the working life of this thing as long as possible so I want to clean it. I've looked at all the tutorials on how to take this thing apart, but have found none on cleaning it. I've read that some people just dip an old toothbrush in rubbing alcohol and scrub, some people soak the logic board and I've just ended up making myself completely confused. I want to give the inside a real good leaning friday night and let it dry Sat and Sun so I can have it ready for work Monday morning (I use my laptop as my work computer, was the deal with my bosses I made to get a job...) Coffee pretty much got into everywhere and yes, I know that this thing WILL eventually die. But it's working and I'd just like to do what I can to extend the shelf life another 6-12 months if possible.
