Cleaning a rusty gun

I saw a GP100 in a pawn shop today. It was nasty. The bore was good and it locked up tight, but lots of surface rust. It was over priced, but if I found a cheap buy on a rusty gun, what could I do to clean the rust?

I've scrubbed off surface rust with steel wool and WD-40. Some of the finish will come off but that goes with the territory. I'm always on the lookout for ugly guns and I've gotten some great guns at great prices that way.:D

If there's no pitting, get some 0000 steel wool and use it dry (dusting it off frequently) to remove the rust. Don't scrub hard and don't let the removed rust build up in the steel wool or on the surface of the gun, it's an abrasive.

Don't use oil during the removal process, it will hold the rust particles and form an abrasive slurry that is hard on the finish. If there's not a lot of rust and no pitting, it should come pretty clean with very little finish damage using this method.

If it's a real rustbucket, the best course of action may be to send it to Ruger to have it refinished, or to an aftermarket finish company to have the finish of your choice applied.

in total agreement with John, i have done this and it works well, i even did it on a Red Ryder BB gun from the early 1950s that sat in my grandmother's basement for decades...seen here in all its glory

Here's my pro gunsmith's method to remove rust, but protect the bluing that's left:

Materials needed:
Kroil or CLP Breakfree. (Kroil is preferred).
A scraper made from sheet brass or a brass cartridge case with the mouth smashed shut and filed into a chisel shape.
A brass "toothbrush".

Apply a dripping wet coat of Kroil to the rusty areas and allow to soak for at least 24 hours, longer if possible.
The Kroil or CLP will penetrate the rust and will soften and loosen it.

After soaking, apply more Kroil and use the brass scraper to scrape the heavier, crusty rust off.
Then use the brass "toothbrush" to vigorously scrub the rusty areas.

This will remove all the rust but won't further degrade the bluing that's left.
Once the rust of off, wipe dry, and apply a coat of CLP Breakfree.
The CLP will continue to "work" on any remaining rust, and will prevent new rust from forming.

Unlike steel wool, this won't thin or degrade the bluing.
You can usually ID a gun that has been steel wooled, there's usually a crater-like area around rusty spots.
This looks like a pit with a crater-like area of missing blue around it.
This is caused by the steel wool hitting the crusty rust like a car hitting a speed bump and causing the steel wool to "bounce" over the spot, thinning the blue around it.

Great advice as usual from Dfaris!! A small addition, I've heard of folks using an early copper penny in lieu of the brass scraper. I've not tried this myself........ Good Luck.

To all that replied. Very informative. I just obtained an old Smith that someone put away in a damp spot 45 years ago.
I think this will help.
