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?
