The keyboard switches arrived earlier this week, but before I install them, I needed to do some flux removal on the components already on the PCB. They keyboard switches aren't sealed, so soaking the board in flux remover would allow some to get into the internal structure of the switches. The flux remover I am using is a specialty product from MG Chemicals that costs about $20USD for 945mL at Amazon. After soldering in the switches, I can use a flux remover pen to target the switch solder points without getting any into the internals of the switches...
