I am taking apart my new macbook tomorrow and am going to have to clean a lot of it (part of the logic board, half the keyboard, cd drive slot <(how do I clean that? Its nasty and hard), etc etc...) What is the best cleaning solution to use? I have 70% alcohol, but I hear 90% is better. I can stop by a drugstore and see if they have some in (I am 15 though... would I run into legality issues?), but I am assuming they will not. Any tips? Also, what would be a good place for looking for blue cellophane? I want to color my keyboard backlight as well as my logo.
