[volt-nuts] OCD About My HP419A Attenuator Switch Gold Plated Contacts

[Chuck Harris]

That is a predominate reaction, but only on the surface.
Under the carbonate layer, you will find lots of nice
caustic KOH.

When I clean up NiCad vomit, I put the crusted parts into
a cup of white vinegar, where they fizz for hours.

I use white vinegar because it is distilled, and as such,
everything in it evaporates freely.  The salts, etc., that
come from this, or that, reacting with the vinegar will
not, evaporate, and need to be rinsed.

I would not, however, expect to find any KOH out in the
outer extremities, where the OP is worried.  I wouldn't
expect to find anything but whatever travelled there as
dust.

That dust, I blow away with compressed air.
