How To Remove Rust From Old Guns
The Penny Method of Removing Gun Rust.
Sometimes you come across a used gun with a shockingly low cost tag and you only have to find out why. More often than non, it's a low-cal sheen and pockmarks of rust on the barrel that will be responsible for knocking some digits off the price, but that'due south non necessarily a reason to put information technology back on the rack.
The video above shows you a fourth dimension-honored method of removing rust that'south almost gratuitous and works very well. In fact, you might take seen an old-school gun guy practice this at 1 fourth dimension or another. The trick these days is finding a penny minted earlier 1982, which were 95 percent copper and v percent zinc.
To beginning, you demand some lite oil (good old three-in-1 will practice simply fine), a medium brass-bristle cleaning brush, some paper towels, and your pre-1982 penny.
Pick a spot to start, put some oil on the metal, rub the penny over the expanse, and wipe clean with a paper towel. Echo until the rust is gone. Utilise the castor to scour the rust out of areas with small crevices, similar a shotgun rib.
The copper in the penny is softer than the steel, and then light pressure will wear abroad the rust without scouring the steel or the remaining blueing. This is why choosing a penny made after 1982 will cause you some serious problems, every bit pennies then were made primarily of zinc, with only traces of copper.
You could apply copper wool scouring pads as well, but keep in mind, they will break apart after some employ. To get the $100 Rossi double-barrel looking good, the guy in the video spent well-nigh an hour working with the penny.
Of grade in that location are other methods of varying effectiveness. If you take an extremely rusty gun, you lot could give this habitation electrolysis method a shot, provided you're extra rubber:
It'south definitely a DIY chore, just the gun owner has some real success starting at the vii:00 mark. The method but requires some rebar, a car battery or jumper box, washing soda (which is sodium carbonate, non sodium bicarbonate, which is blistering soda), and a container big plenty to submerge everything in water.
Calculation the electric current causes the molecules of the gun barrel that accept turned from steel to iron oxide—rust—to flake off. The rust is then attracted to the less noble rebar with the current running through it, serving equally the anode. It's referred to as the sacrificial metal, since it sort of takes on the oxidation.
Here'due south a good step-by-stride electrolysis method to restore old tools that would work just fine on gun parts.
However, remember that whatever metal parts where the rust is removed will result in exposed blank steel, which can re-oxidize apace. Exist certain to oil everything down immediately. Electrolysis could also remove rust-bluing, so be aware of that too earlier starting a project.
Another method for mild rust is to just soak the metallic part in distilled white vinegar for a few days. Every bit you can run across in this video, it does a great task, but, once again, plan on rebluing the barrels later, since vinegar will remove any old bluing that might be on in that location.
