First get some q-tips and rubbing alcohol and remove *all* the
corrosion. Next clean the terminals with some extremely fine sandpaper
#400 should probably do the trick.
Make sure there is no trace of corrosion or pitting and you should be fine.

I've read all of these suggestions and wonder about those who suggest
using sandpaper or an abrasive. That might work in a compartment
where the batteries are arranged horizontally in the device body, but
so many devices have deep and narrow vertical battery compartments.
I couldn't work with sandpaper in the battery compartment of my Nikon
Speedlight.

I guess one could superglue a circle of sandpaper on the negative end
of an old battery and spin it around, though.

I have used an eraser with some success, but it was one of those
grittier erasers found on the end of an erasable pen.

An eraser such as you have described should be fine.

True, but many contacts are coated with a conductive metal, such as
silver. It is easy to overdo it with emery, which is why a suggested a
pencil eraser, after a careful chipping.
