Rust removal help

[cmgee67]

I noticed some rust on the bottom of my metal rear sight where it touches the slide and I can't find anything thin enough to get down and rub it off with it being such a tight space. Pistol is Glock 19 and it's due to body sweat from carry. Note: it's not the slide that has the rust it's the sight

Try wrapping a bit of steel wool around a thin splint of wood.
Lubricate with oil and rub out the rust.

I will try that. Thank you

The sight is there to stay. It is screwed with a set screw and loc tite.
