Hi all, My Remington 870 Express (barrel date code 1990, it has a matte gray finish similar to parkerizing) was left out in a leaky garage during a rainstorm recently. I just retrieved it and the entire receiver and barrel are covered with a medium speckling of rust. Fortunately all of the internals are fine because they were oiled. I have no idea how to go about removing this rust because I've never had this happen before –– the rust is sprinkled over the entire exterior of the firearm. How can I get this off without damaging the matte finish beneath it? |
| Kroil does some amazing stuff to surface rust too. I'd try soaking everything in that for a few days first before breaking out the steel wool. I've had excellent luck removing even pretty heavy pitted rust from some older C&R weapons with Kroil. Then I usually liberally clean it with #9 and soak in CLP which I let dry for a few days before wiping off any excess. That usually does it. |

0000 steel wool and 3n1 oil has never hurt the finish on anything I've used it on. It will remove surface rust and even rust from a pit, but if pitted the pit will still be there.
don't use naval jelly - yes it will remove the rust but will also remove the finish (bluing or parkerizing). |
Hey thanks guys. I do have some #9 handy so I'll try hitting it with that and see what happens. I appreciate the advice –– I've never had to deal with a layer of rust before!  Out of curiosity, would the same information apply to a glossy blue finish? I have an old 70s Win 94 and it's a great rifle but a little rusty in a couple spots. I've never tried to remove the rust for fear of damaging the finish. |

clean it with some #9. rub hard and change the rag offen. then oil heavy. rub the oil in. this should take care of it. if not then you might have to go to the steel wool. remember steel wool will also take off the finish if you don't use the correct type. The steel wool you need to use is the 0000 one. This one is the finest they have. You can actually use it to clean chrome! It won't scratch it and leaves a mirror finish. Something I learned in my younger years working paint and body. |

I've never tried to remove the rust for fear of damaging the finish. Oil and 0000 steel wool will take the surface rust off a polished blue surface as well. Just be careful around edges and corners. You can polish long enough to take off the blue, but that will take a while (some practice on a scrap part or hidden area under the wood will tell you how long you can rub without damaging the bluing) One other thing on that Win 94...the receiver of guns made through the 1970 were not blued with traditional methods. They use a plating type of coating. Flaking or speckling on the receiver will not come off (with your steel wool) or respond to touch up blue. |
