Yea, big surprise there. Sounds like he gave it a good bath in the
stuff if that happened. 'Routine maintenance' should never involve
spraying it all over the place, or even without the red application
tube that comes with each can. I spray the tube pins very gently, or
wipe them with a swab soaked in the stuff, then apply and use the
action of replacing the tube in the socket to clean.

It's also been known to cause certain phenolic wafer switches to
swell, rendering the switch frozen or very stiff, at best. Seems to
mainly bother the older 30s/40s stuff. Yet another good reason to use
it sparingly.
