Hello all, I have inherited a late 2008 Unibody MBP 15" with some keyboard problems. According to my friend (the previous owner), a small amount of wine spilled on it. The computer powers on and runs fine, but the backlight is barely visible in the right and left sides of the keyboard (only the middle is illuminated) and several keys including Backspace, Esc, F3 and F5 do not work. I am able to see some sticky residue but it is under the plastic liner beneath the key and I can't really clean it without dismantling the whole thing. The computer doesn't display any other issues, and it's in generally decent shape, leading me to believe the motherboard was undamaged by the spill (the only reason I'm considering repairing a machine this old with this type of damage, honestly). Does anyone have any experience with this type of repair? Is it feasible to clean it with isopropyl and a swab, or is it best just to replace the entire keyboard? Since the computer has to be dismantled from the bottom up, it's quite an involved process and I'd like to know what I'm getting into.
