Cleaning rust off of metal.

[A. F Medic]

I might start a fight here but I have had tremendous luck using a 100% copper coin and Sea Foam's Deep Creep Penetrating Lubricant.
Coin collector gave me an old Canadian coin that was solid copper. I used that to remove the rust. Modern coins have copper over aluminum. Scratch like Hell! Church is over. Go in Peace.

I've heard that...

I use bronze wool and Kroil. Does not harm blue or parkerized finishes.

After...

I've used steel wool, 4F fine...and have achieved exactly the same results with oil. Many say it's not possible... It's the oil that keeps it from scratching.

Kroil is the bomb for a solvent. Big 45 Frontier Metal Cleaner and some elbow grease.

Was taught that trick several years ago by the late Tommy Hawes, who had been an engraver in Colt's custom shop. I bought a 76 Winchester from him that had some small rust freckles on the barrel, I will never forget what he said " you take some light oil and a penny and lightly rub the rust spot and that barrel will come up shinier than a dime in a goats ***" and it did.

Easiest method is a light touch with a fine brass wire wheel in a bench grinder. Eye protection is mandatory.
Same light touch with a brass wire wheel in a rotary tool.
If all else fails, usually meaning you have neither, 0000 steel wool and light oil will do it. Steel wooll has gotten expensive and not easy to find though.

I've used a pre 1964 copper penny, (US or CDN), and a custom sharpened brass scraper. Be careful as bits of steel rust will embed and scratch if you aren't diligent about keeping it clean. I like Hoppes No.9 and 0000 steel wool for clean up. Works like a champ. I carefully did the tops of a set of barrels from a lovely little pre-war Fox Sterlingworth double a few weeks ago that had been in a rack near the Atlantic ocean in Florida with no care for many years. The blueing was damaged but I was surprised that there was really no deep pitting once cleaned up using this method.

I've ended up with a fine set of brilliant white spots after...and perfect blue. Then we took the affected parts and put them in a good strong solution of bluing tank salts. Came out with a perfect cover and you couldn't tell...just like new.

Guess I'll jump in too .

Stainless steel scouring pads by 3M. Get 'em near the dish detergent at the supermarket.

Scrub hard, dry, with no oil. The wipe down with an oily rag. Miraculous, really! Don't worry about hurting the bluing (HONEST!) just scrub hard. I've not scratched up anything with these.
