One must likewise clean the black conductive pads on the back of the rubber buttons.
Action 3: Resoldering Micro-Switches
If a switch has actually fallen off, it needs steady hands. The switch must be lined up with the solder pads on the board and carefully re-attached using a fine-tip soldering iron. Caution is needed, as excessive heat can raise the delicate copper traces off the board, ruining the remote permanently.
