[Test-Equipment] Washing electronics

[Charles Mumphrey]

I agree with your one way of cleaning, Sir....Just FYI...IMHO...I would
NOT recommend this cleaning procedure to be used by a "novice" 
electronic technician unless there was some "learn'ed" supervision.
Unless,  the "dirty" electronics is possibly a learning tool and could
easily be replaced, or, not of great value if "Kill-Roy" came a
knocking, Hi, Hi!  But then again, could be a "Ham" thing.  :-}
