Remove the corrosion with vinegar or acid (ammonia)-
based window cleaner.
Ammonia is an alkali, not an acid. I've used household ammonia for years, and
never had problems. Once the contacts were cleaned, they stayed clean.
There are disagreements among us as to whether Energizers or Duracells are
more likely to leak. Every modern battery that has leaked in my equipment has
been a Duracell. I don't use them, unless they're the only batteries
available.
According to the chemists, ammonia is a weak acid. (So weak that some
think it is an alkali).
I recently found a duracell that leaked in something i have. Merely used
some window cleaner to remove the gunk. Shelf life OK, useful life once
installed questionable.
YMMV
