How to remove light rust spot from blued barrel

[Eric Gregg]

A friend of mine has a 1100 Remington 12Ga with a blued barrel that has light rust on the outside part of what would be the chamber area.
Is there anything that can remove the rust without scratching the barrel or removing the bluing off of the barrel?
Or, would this be a great project for a local gunsmith?

Thanks

 0000 steel wool and WD40 will shine it up real good and remove the rust unless it's pitted. Not dry steel wool!!!!!!!

I soak an area that has very light rust with WD-40 and let it sit for some time and then use a soft cotton cloth to see if it will wipe off. Normally, some or all can be removed with this process but you may need to repeat it.

Another good method, if you're careful, is to use some "Mother's Mag & Aluminum Polish", Wal-Mart is a good source. It will remove very fine rust. I apply it with my finger, allow it to work and then very lightly polish with a soft cotton cloth.

I've also used 0000 steel wool (very, very carefully with a light touch and as stated, I keep it wet with WD-40) or very fine brass wool, which is what I prefer, if the other process does not remove it.

The real key to all the above is patience and time. I'll work on it for a while, then walk away from the job, so that I don't get carried away and cause more damage than I'm curing.

P.S. We can all prevent this problem by using some of the vapor technology products that are available several places under different names. You just put some in your gun cabinet, safe, etc. and allow it to protect your guns, inside and out.

Ditto to the other comments.

Oil and a rag to start.  If that doesn't work, oil and a bronze brush. Still no dice, then oil and 4/0 steel wool.

I wouldn't have believed it until I seen it done one day. But I witnessed a guy do it with oil and the edge of a nickel. I did it on a old 22 of mine. But I wonder if someone else ever heard of this? I would go with soaking with oil overnight. Then on the next day use some more oil and the 0000 steel wool as mention above.

Once you do get the rust gone, tell your buddy to invest in some sort of Birchwood Case Barricade be it the pre soaked rags, the squeeze tin, or the aerosol spray bottle! If the firearm needs to be stored for any period of time after a hunt its bar none the best protectant on the market!
