soft rust removing
 

I used Never Dull to get rid of lightly rustes areas on edged weapons. It is soft and does not scratch at all like steel wool, but I guess Never Dull can remove the blueing of the gun, too.
Does anybody have experience with the use of Never Dull on a blued surface?

I have used it on brass to clean it and it will remove that finish so be careful..I believe it will do the same to the blued...
