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.

What is in that spray and how does it work?
I have some that I use on car batteries.
I would think that it would insulate the cell from the contact.
