Not sure...
...about the first one.
I can recall dismantling a keyboard and scrubbing, literally, the PCB under the tap after a user spilt a sticky orange drink (probably Fanta) on it. Given that a decent keyboard could be over £100 in those days it was worth doing.
The keyboard did recover and continue working, and it probably avoided an embarrassing conversation for the user with his boss.
Sadly the users today are no better, I've had to write off a laptop recently due to Coke (the Cola variety) damage,
