Birchwood Casey makes a chemical that removes bluing. In addition, Naval Jelly, a popular rust remover, will also remove gun bluing. (Bluing is a form of rust) Be certain that you are dealing with blued steel, and not anodized aluminum. A magnet will not stick to aluminum, but both the Birchwood Casey product and Naval Jelly will corrode aluminum alloy very quickly.

Bluing, as it relates to firearms or metal in general, is a permanent surface treatment under ideal conditions. Poorly maintained bluing will fade or flake off. Bluing is a "form of rust", an oxide layer on the outside of the metal. You can remove it using various abrasives, but yes it is permanent.

I am sorry but it can not.
There are several reasons bluing will not take on a gun. One is it stainless steel. Nope. Two is the bluing solution correct. If so, is the temperature correct, Brownells has bluing info for their solutions., follow these almost perfect. Also to be blued, it must be alloy steel. not pot metal, not cast, just steel. Don't get any brass, copper, zinc or lead in the bluing solution. lcjones
To make Mrs. Stewart's Bluing at home, you will need basic ingredients such as water, laundry bluing agent, and a container for mixing and storing the solution. However, it is recommended to purchase Mrs. Stewart's Bluing directly from the manufacturer to ensure the best results and avoid any potential safety hazards.
