Perhaps that may be so, in part, but if you take

I don¡¯t know about NiCad cells. But bubbling would not surprise me on a crusty leaked alkaline cell, as the stronger acetic acid would drive out the carbonic acid from the salts in the crust, and carbonic acid is unstable and comes up as CO2 bubbles.
Vinegar is also a decent way to remove leaked alkaline batteries from
a flashlight, or damage from leaking batteries in a piece of
equipment. You'd like to get the vinegar on as little extra circuitry
as possible, of course.
This also works if the battery "fluff" has cemented the battery in
place. May take a while, but it does work.

There is so little CO2 in the air
Don¡¯t we all wish that were still true¡
that you really
cannot expect it to clean up your mess.
No, in particular not if air flow was restricted (as in a closed case) ¡ª there is only 0.04 % CO2 in fresh air (current value ¡ª I memorized 0.03 % when I was in school).
But with a little air flow (in particular if there are humans in the room, which drive up CO2) and a little time, there will be little hydroxide left.
You still have to clean up the carbonates!
(If you do get a little hydroxide on your fingers, the skin fat turns to soap, so you easily know.
Not that I recommend that as the test¡
But maybe you can think of fixing leaky battery cells, and the fingers only rarely turn soapy, usually when there is no crust.)
