I did not bother with the danger of removing cables or cards or logic board. I spent 30 mins removing my battery carefully, using string and CT1 multisolve which isn’t dangerous to plastic.
i slid my string under the battery and see-saw underneath and sprayed Ct1 Multisolve underneath. I’ve now done both my macbooks. Didn’t destroy any cables or risk it. I put a few paper sheets over my logic board to cover any spray back. Simple see-saw and a palstic card, the blue spludger and the black long spluger.
This video shows how to do it safely: https://www.youtube.com/watch?v=AabLlHT5...
Undo the 3 cables gently. remove the airport card. gently pry away the cables fro the fan plastic. then the camera cable will slide out easily.
