Vinegar is good. I also use plumbers' fitting brushes, to
scrub the inside of the barrel. Pull the spring out, and
also brush where the spring meets the tail cap, and brush
the end of the barrel (the end of the barrel is electrical
contact, to the tail cap and the electricity also goes
through the spring.) Leave the cap off for a day or so, let
it dry inside. Grease the threads of the tail cap after it
all dries.

Do you know what chemical can clean an anodized aluminum
Mag-Lite
flashlight when Duracell March 2013 alkaline batteries
leaked.

The flashlight itself seems to be black anodized aluminum.
The bottom
Duracell March 2013 D-cell battery leaked and started
corroding the steel
spring in the bottom end cap. It left a gunky grayish white
gritty goop on
the spring.

Likewise, the grayish gritty goop expanded the battery such
that it was
stuck inside the 3-D-cell flashlight. After about 10 minutes
of banging
upside down, I was able to extricate the three D-Cell
Duracell batteries.

I generally use vinnegar to clean up scale in brass water
faucets. Do you
know what chemical I can use on aluminum & steel flashlights
to dissolve
the grayish gritty goop from a leaked alkaline battery?

What is that goop made up of anyway?
