I've never needed to separate keyboard from shell for verdigris removal; I might try agitating for a few minutes in dilute bleach (pressing keys while doing this) then bicarb then wash with clean water for a *long* time then dry. What I think I'm saying is that *almost* anything is preferable to taking the keyboard apart! It is possible, the chances of wrecking the keyboard are large. Remove the heat stakes - use a sharp knife to remove the 'overflow' of plastic (i.e. NOT the actual stake, just the excess stuff that is keeping the board against the stake). Wash as described. Reassemble and while holding the board onto the stakes, use a soldering iron on the centre of the stake to spread it. Be sure that the power and prog-run switch are assembled before you do this, there are few second chances. I additionally use a piece of foam rubber to hold the battery compartment against the keyboard PCB as heat stakes never fully reassemble! Good Luck, you *will* need it!
