Default best rest remover

Best rest remover is children. How bad is the rust some needs 0000 steel wool...how bad... wire brush on a drill or grinder? Naval jelly ain't working you need to get sand blasting bad? Got pics!

Unless you just have a ton of time, take them to a good gunsmith and have them parkerized. If a gun has really been rusty i have never been able to get it back right with bluing. for minor rust we use a penny to rub off the rust and not effect the finish.

The rust has to be removed before rebluing. Heck for that matter, parkerizing, or Duracoating too.


That rust has to go.

The best rust remover I know of is oxalic acid. You can buy it at a hardware store or a big home improvement store as wood and deck cleaner. It's a white powder and you mix it about 4 rounded tablespoons per gallon of very warm water. It doesn't seem to matter if the water later cools, but it must be mixed warm.

You can also get it in bulk on ebay, but at the hardware store you'll find a 12 oz can for about $9. Much cheaper in bulk. Be sure to read the ingredients on the can to be sure it's oxalic acid.

It won't penetrate oils or grease so you have to first soak and clean your parts with brake cleaner or lacquer thinner or something. I even follow that with Dawn dish washing soap. Be sure to scrub the barrel inside.

Barkeeper's Friend is a cleanser which contains oxalic acid for small things. Find it at the grocery store next to Comet.

Wear rubber gloves.

I restore old bicycles. Here's a picture of a 55 year old rusty chrome wheel after I soaked it in a Rubbermaid tub for 24 hours and rinsed it with water.

There was absolutely no scrubbing here - just soak and rinse.

PS: It won't hurt rubber or plastic.

thanks adapter for the info . I am another guy that see beauty in old metal forms and am always fighting rust so this is another item in my arsenal to fight the battle against rust. Being that its also organic is also a plus.

I really think that the naval jelly should of worked , maybe some thing was not done right.

That was a good suggestion.

Grinders and pads will wear you out and gouge and remove good metal and leave oxidation in pits , only to return.

YOu could also use a tub (not metal) filled w/ water and baking soda (1 teaspoon per gallon). I like to use some screen from an old door or buy a roll. This will act as your sacrificial anode and will get eaten up instead of the piece you're using.

You will also need a battery charger (trickle charger, don't put in on jump start-2-12 amps is great!). Connect the red lead (pos. + ) to the screen (or whatever piece of metal you're using. Now this works on "line of sight", so if you place , say, a rod on the bottom of the barrel, the top will not be removed. So use a larger piece. Connect the negative side (-) to the part to be cleaned.

Now using more baking soda will not help. It is the electrolysis that is doing the work through the current. Lightly rusted objects will take only a few hours. You will see the solution bubble. This will also help loosen heavily rusted objects. Make sure you have it connected right, or you will find your part eaten away!!!!LOL. The solution is harmless, but you may want to use gloves if you have sensitive skin, but again, not needed.

When done , the object will need to be cleaned (wiped off-usually), nothing more than paper towels or a 3m pad.

Let me know how it worked out for you.

Posted this in another topic about removing rust.....

Here's one most people don't know of. My grandfather worked in a shipyard during the WWII and way back when, they used molasses to remove rust, yep molasses, hundreds of gallons bathtub size. Obviously curious, I had to try for myself. Mix the molasses around 60/40 with water (60% water), even a weaker mix of 60% works (experiment) I used warm water to help it dissolve better. Leave the item in the mix for a several days, after a day or 2 it will start to form micro bubbles on the surface....in an outline of the object in there. No scrubbing, no acids, no effort. I cleaned up an old woodworking hand plane blade by this method. It cleaned it so well, you could see the temper line where the blade had been heat treated. After taking it out of the mix, I'd say within several minutes, orange (rust) was starting to appear, it cleaned it that well.

whenever you "grind/sand/bast/steel wool" you are also removing very small amounts of the metal itself as well as leaving possible "scratch marks". The molasses does not do this. I'm not a chemical engineer to explain why it ONLY eats rust and nothing else but to clean it back so you can see temper lines is good enough for me

was looking at a Midway catalog last night and came across this rust and gun blue remover. I have used this stuff in the past and it worked nicely on the rust. I bought it at my local Home Depot or Auto Zone dont remember exactly but I know it was from either of these stores, it was a while back.

I have used CLR for rust. It just loosens the rust first and then you use the steelwool to finish it off. CLR will also take off any bluing or other types of coating so use just what you need just in case you don't intend to do a full refinish job.

Take it apart and use electricity. I think this is a clip of what to do. It was on Spikes powerblock trucks. Use a battery charger, arm and hammer washing soda and a plastic tank of water. It at the last few minutes of the show.

Coke syrup is best but a few good old cans of Coca Cola will remove rust.

You will have to soak them in a good degreaser first as any oil on the metal and rust will stop the Coca Cola from reaching the rust

That's because Coke contains phosphoric acid which is the rust removing ingredient in Navel Jelly. Phosphoric acid converts iron oxide (rust) into iron phosphate which is water soluble.
