[ARC5] Batteries That Do Not Corrode

[Michael Hanz]

I normally use 3M ScotchBrite (Fine) for this, Wayne.  It will dig into 
the crevices because of its flexibility and you can use scissors to cut 
out a very small pad, which you can use with a small screwdriver to 
massage the area.  Wet/Dry sandpaper could be used, but it doesn't 
follow irregular surfaces as well.  I do apply a _thin_ coating of 
dielectric contact grease just before inserting the battery.  It will 
leave a tiny ridge around the contact surface of the battery, but 
inserting the battery will wipe that away from the contact area itself.  
I would perhaps suggest a log of items that use these infernal things 
and check them once a year - if you have time.  The abraded surface 
isn't as protected as the original plating and won't last as long.
