Safely. And if so, what would that be?

A rather expensive flashlight has a battery pack insert that was crudded up. Sort of impossible to clean manually with a brush.

Most people use IPA/rubbing alcohol. I will also use a scotch brite scrap if warranted.

I've had success using White Vinegar, I use it on a Q-Tip and then do a clean-up pass with just water on a Q-Tip.

The best way to remove alkaline leakage from the device is to neutralize by carefully dabbing with a few drops of a mild acid like white vinegar or lemon juice. For stubborn leaks, an old toothbrush dipped in vinegar or lemon juice gets the job done. After the leakage has been neutralized (fizzing stops), carefully dry the area. After the area has dried thoroughly, the metal device contacts can be scraped to remove any residue and then polished using a pencil eraser.

I just saw Techmoan on Youtube cleaning battery contacts on some old MD players using lemon juice, since the battery leakage is usually alkaline, the citric acid dissolves it.

Were the batteries that leaked a major brand? If so, major battery brands will pay for a replacement. You would have to send the damaged unit in.

Do they still offer that guarantee? I quick glance at Duracell's web site and I could not find any links about this. maybe it's there but they surely don't want you to find it.

Quick search with DuckDuckGo:

Posts seem to address leaking Duracell batteries with mixed results.
