As everyone knows, batteries unused for a long time will corrode and spread that corrosion to the battery contacts of whatever device it sits in. What's the best way to clean that corrosion off?
In the past, I've used q-tips dampened with white vinegar (essentially acetic acid), followed by q-tips dampened with water to remove any residue and acid. Is there a better way to clean the battery contacts?
