Spilled some soy sauce on my A1314 wireless keyboard that caused the keys to be bit sticky. After reading this thread, I removed the BT circuitboard and went to the kitchen. Sprayd the whole keyboard with dishwashing soap, thoroughly brushed it and then rinsed it. Blowed most of the water of using air in can and then dried it with paper towel. Couldn’t bother waiting for it to dry, so I just assembled it and threw in the batteries.
Tadaa! it works (and looks) like its a brand new keyboard. Nice!
