Start with 0000 bronze wool and oil.

Disassemble and follow Mssr. Elegante's advice. Bronze wool is the key. DO NOT USE STEEL WOOL. For the oil, I'd recommend this product....

Bronze wool can also be had at Brownells.

you can also find copper wool. I would at least spray a bunch of WD40 to get the rust loosened up

Electrolosis if you dissasemble it. I have a tutorial somewhere in the gunsmithing section. This would effectivly remove the rust and leave the finish intact.

Electrolysis may strip the bluing ... It depends on a number of factors

Start with oil ... You would be surprised what will wipe off after a soak in penetrating oil

CLP

i suggest beginning with oil without the aid of abrasive action; see what you'll get off 'for free' before having to work for it.

[bohoki]

i'd just oil it and brush it with a toothbrush maybe a bit of air compressor blast

update?

Please post pic of the rust

i think the result of minimal intervention will be favorable.

I would start with CPL and the least abrasive method (a cloth first) them move up to a toothbrush and what ever you havde between that and steel wool.

Froglube and a toothbrush will make it all better... you can warm the area with a small torch lighter and it will be easier. Just be careful not to overheat anything
