Default Removing battery corrosion

This is a vintage transistor radio, likely using a carbon-zinc battery (LeClanche Cell). They use an acid-based electrolyte. As carefully detailed. Latter-day batteries *tend* to use alkaline-based electrolytes - making most of the discussions herein accurate. But - not in all examples of all cases.

I try to advise based on good chemistry based on the data as presented.

Crap, right, as the OP stated zinc-carbon battery using either ammonium
chloride or zinc chloride in the electrolyte which are indeed mild acids
and thus you are certainly correct to recommend using a base material to
neutralize it.

Should have realized you wouldn't make that sort of mistake and double
checked my own assumptions.
