Protip: once you dissolve as much of the gunk as possible, take a small metal brush and give the contacts a scrub. If they're coated, this helps open up metal contact surface to give the new batteries a chance.

But if the contacts are too corroded, you may need to MacGyver something with a soldering iron.

please advise how to dissolve the gunk at home (using household items, cleaning products, or something that is available at local stores).
