Electronic flash has corroded electrical contacts. Duracell AA
batteries leaked. The contacts are molded into a plastic holder and
cannot be easily removed. I have cleaned the metal contacts using a
diamond tip. I did this a few months ago and the contacts re-corroded.
Again cleaned but what can I do to retard corrosion? Some in place
coating or plating?

They have an anti-corrosion spray for car battery terminals. Clean
the terminals via what is easiest, spray some of the anti-corrosion
on some q-tips and rub on contacts.
If possible remove all pits from contacts since this tends to enhance
corrosion regardless of treatment. Filling and shaping with solder
might be an option if damage to other parts of the device will not
occur. Tricky, so this might not be an option.
