Hey all - a number of my firearms have some markings on them where brass has rubbed against them. I've tried CLP, patches, a rough textured towel, and a cleaning toothbrush, nothing removes it.
I'm no metallurgist, but it seems to me brass smudges should be easy to remove from hardened firearm steel
. Any tips? I'd like to avoid sandpaper of any kind as I'm fearful of altering the finish, even to the slightest degree.
Thanks all!
