Do you know what chemical can clean an anodized aluminum Mag-Lite

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?

Had that happen on a 4 C cell Mag. Luckily I had a soft bronze wire brush
just oversized of the bore. Used spray silicone and brushed the inside
out. Brushed the spring and bottom cap and sprayed with silicon. Works
fine now. I don't use Duracell batteries now. They are known to leak
especially when the get low.

yeah, just use a bottle brush and lots of clear water. then spray it
with something to keep future corrosion at bay. Spray silicone is a
good idea.
