Default removing corrosion from battery compartment

Ideas for getting battery acid/corrosion out of a battery compartment.

I know on a car battery you use baking soda.. but in a case of this I
am afraid the solution would leak into the device.. any ideas...


Clean out as much as you can with a stiff bristle brush, like an old
toothbrush or something. clean off as much of the metal corrosion with
an ink eraser, like on the end of some pens, or a typewriter eraser
(remember those?).
then spray with electronic contact cleaner, or just use WD40 like the
guy said.
It might or might not be perfect afterwards, though; might become the
kind of item you have to slap once in a while to get it working.
