[NTLK] Cleaning or restoring battery cage contacts

[Steven Frank]

I just got hold of a new-to-me OMP battery cage.

It looks like it's probably usable, but a couple of the spring
terminals have a little bit of corrosion.

What's the best option to clean, restore, or replace these corroded terminals?
