While wiping down the barrel of my shotgun, I came up with a little bit of rust residue. Subsequent wiping with hopes continued to bring out residue. Any suggestions for gentle treatment?

Do you mean the actual bore, or just the outside of the barrel?

WD40 and fine steel wool ,, rub gently

I just wipe my guns down with oil. Never had any rust beside on my glock...

Just on the outside of the barrel. Bore is clean.

 

Fine steel wool? Isn't that still going to mar the bluing?

Oil and green scotchbrite pad.

Oil and green scotchbrite pad.

+1 or brass brush

steel wool= 0000 or very fine scotchbrite and keep it wet with oil

I just had this on my pistol, and I found the perfect way to correct surface rust. Send it back to Ruger they fixed it and now my gun is as good as new. (sorry I know this wasnt helpful but I just wanted to boast a bit lol)

LOL, next time use the dry cycle on your dishwasher, everyone knows that..

Keep the WD40 away from your gun. 0000 steel wool and CLP

Good suggestions, but I am not a fan of Steel Wool, I like Brass Wool, not a big deal on guns but I like the even softer metal as well as steel wool will rust and while you will clean any steel wool that get on your gun off, if by chance a small piece get lodged in a tight spot like around a scope mount or other location like that, it will promote rusting.

I use the Scothbite pad (a partially worn-out one so it's not too aggressive) and Barricade Oil, which seems to do the trick really nice, without any metal filing residue which will promote rust in tight places like Harry said.

Kroil and scotchbright pad. Very gently work it in , let it sit, then reapply and keep doing that till it is gone.

I haven't had to take rust of any guns, but for any of my tools that rust, I soak them in PB Blaster. Works like a charm. No scrubbing at all.

You might want to try "Big 45 Frontier Metal Cleaner". I use it for cleaning bores and removing rust from any metal. Works great with Rem Oil or other "light" cleaner. Google it and I can say it does all they claim.

I was reading a very good article on firearm rust removal. The writer said not to use oil while using steel wool, but he also suggested, if I recall correctly, to not use steel wool..use something else. It frustrates me that I don't exactly remember this, so I am going to try to look for the article today.

Just use a rag and gun oil, you will most likely continue to get rust off your shotgun barrel it is part of the blueing process.. unless it is pitted then you should follow the directions to spot blue it..

Just on the outside of the barrel. Bore is clean.

REALLY fine, as in 0000 fine, and i'd personally use Kroil as opposed to WD-40. Give it a good coat of Kroil, let it sit for 5 min then lightly hit it with the steel wool, it wont mar the bluing, i;ve done it on a few guns over the years and have had no issued with finish

This is what I use. Squirt some on the gun, some on the steel wool, and rub with light pressure.

Hit it with the bench wire wheel, just to be on the safe side.

 

 

On a more serious note, I agree about using very fine steel wool and oil. I have used it on some firearm parts with good success, among many other things. Hope you have plenty of elbow grease.
