mklotz,
Thanks for that little tidbit of info!
I actually did think of using vinegar, "the wonder solution", but didn't.
However!
I recently bought a small bag of citric acid powder, and use it all the time for removing rust on steel.
It works miraculously well! I heat it up a little, not sure that's necessary however.
I WILL try it in the maglite and report back!
