[R-390] battery corrosion question

[David Wise]

Vinegar does a great job.  Swab it on until it quits foaming, then rinse with water.

ED, try pencil erasers first...

I have a much-favored digital clock that I managed to neglect just enough to
wind up with some corroded battery terminals. It LOOKS like it didn't
spread, but I want to deal with the contacts (and their immediate vicinity)
first. My thinking is, that since the batteries were 'copper-top' alkaline
batteries, that I ought to start with a careful wooden Q-Tip application of
some very mild acetic solution (I'm thinking white vinegar) to neutralize
the alkaline corrosion. My friend Ken says no, I should use a baking soda
solution. Anybody like to chime in? Helpful advice gladly solicited!!!
