Surface rust on a Remington 870 Wingmaster

Be careful , go slowly , and use the least harshest and least abrasive material you can . avoid wire brushes like the plague .

Fine copper wool, 0000 at most. Use lots of lubricant. Another good cleaner that isn't hard on a finish is Turtle Wax Chrome Polish and Rust Remover. The model 58 in my avatar was full of fine surface rust and a little freckling.....Working slow and careful with Turtle Wax CP & RR and a rag salvaged the finish. It doesn't look brand new but cleaned all the rust off without removing any of the original blue finish.
Steel wool , sandpaper , wet or dry abrasive, all will remove the blue right down to bare steel.
Try a cleaning and polishing with a rag and Turtle Wax Rust Remover, no power tools , do it by hand , a small area at a time, and watch, as the cleaning progresses, the rag will at first turn brownish-red
as rust is cleaned off, when the rag no longer shows this color, it will just be a grey color...stop . You have removed all the rust. Move on to another area and repeat. Then protect the cleaned surface with a coat of wax, this also makes it look good...like waxing your car !

Told my friend what kind of a price he could expect to have the rust removed and re blued and he balked at the price .. they don't have it to spend .. they're a young couple struggling in today's economy so not sure what he will do ..

I told him I would be interested if he wanted to sell it .. but he said that wasn't an option either since it will be his wife's if her dad passes .. since it is owned by her Father ..

I told him something needed to be done to stop the rust that it would only get worse ..

He asked me to thank everyone who replied with comments .. I showed him this thread ..
 
I know the op is not going to touch the shotgun, but this is how i have dealt with similar situations.

Flatten a rifle shell into a brass scraper. Nock the high spots of rust off with it. Do it dry you want the rust to fall away not get rubbed in. I have been amazed how big a rust spot can form on top of the finish from one little pin hole. The brass won't scratch the blue, but the rust is very abrasive.

Blow off with air, oil & rub with a rag.

Not my gun or expense but I hope this Wingmaster gets the refurbishing it needs. Should provide years of hunting or target use. Plus as we all know the new ones are very expensive. The old Wingmasters sure looked quality with real walnut and decent bluing the way a gun should look. I won't share my comments on the "Express" jobs but do not care for them. Best of luck and would love to see a pic if you go ahead with the work.
