With all due respect Eric, the only reason I can think of that it would be necessary to remove flux after soldering, is if the WRONG kind of flux (and solder) got used...?

ANY electrical connection should be made with rosin-core (or hi-tech equivalent?) electronic solder, any residue of which is
totally inert to the connection. (as can be seen in Ryan's pics -- obviously no unusual "corrosion" present, though some of the original rosin flux clearly remains)
Now, on the very unfortunate chance that some unknowing individual would have used "plumbing/plumber's" solder (otherwise called "acid-core", OR a solid-wire solder with a separately applied flux) on the poor thing somewhere along the line...yes, THAT will most definitely turn everything into a greenish-white powdery MESS of uselessness, after a decade or two...

Removing rosin flux residue (any kind of alcohol works BTW...rubbing, denatured, even Windex!) could make it
prettier I suppose...especially when resoldering onto 'old work', it can be helpful to remove excess old flux
first, which will just re-melt and re-flow (and smoke like h*ll while doing so

) into the new connection otherwise.
