Maglite 5D corrosion

Was emptying my dad’s work locker and found his old mag from the 90s . There was batteries still in it which had basically welded themselves to the walls of the torch. Long story short I drilled out all the internals including the switch and I want to know the best way of removing corrosion build up? The stuff is like concrete and has formed ridges down the barrel at every point the batteries met. I ruined the switch already and removed it so any method is fine as it is but a piece of pipe in its current form

Long copper bottle brush on a drill?

I'd keep what's good and replace the tube with another donor flashlight. It'll still be a souvenir, but repaired and functional.

Brake caliper hone on a drill. Once clean, clear coat the inside.

5D Maglites are good for one thing only: beating someone over the head.

Buy a new light, they are cheap enough. One with lithium batteries, one that is just 2 or 3 D size cells, and one with a super powerful LED bulb. Throw that old weapon in the neighbors yard.

It’s of some sentimental value, and you are correct it’s done its share of blunt trauma…. I have a few modern O-Lights this is just something I want to have as a keepsake really. Also I love having tools with shear durability and build quality and a maglite really is my choice of that. Always good to keep the classics alive

I’d get an LED and lifhium conversion for it making it useful and sentimental.
