Gunsmiths and firearm enthusiasts use bluing to help protect a gun from damage.
Gunsmiths will use a hot bluing method to oxidize the steel. The rust that forms is turned into black iron oxide, which gives the metal a bluish tone. You can also cold blue a gun, but the protective coating isn’t as durable as that of the hot bluing.
If you have a favorite pistol or rifle that starting to show some red rusty spots, you might be leery about trying to remove it because you don’t want to ruin the bluing. You can remove surface rust using these 3 methods, which center around gentle rust removal followed by lubrication.
Before you start, however, protect your gun from any moisture and make sure it is bone-dry to avoid any future rusting.
