Light surface rust on matt black scope rings

[jpx2rk]

Searched and didn't find anything relating to matt black finishes.  Have a 25 y/o Luppy Vari x3, and the related scope rings both in matt black.  Noticed a small spot of surface rust on the top half of the mounting ring, what is a good way to remove the surface rust on the mounting ring, none on the scope.  TIA

If oil itself does not take it off then gently scrub with 0000 steel wool and oil.

Plus one on this. If it doesn't look good to you after take a small bit of cold blue on the 0000 steel wool and lightly buff the area. My favorite for this is Oxpho blue from Brownells

Also, Dremel with a cloth polishing wheel used veeeeerrrryyyy lightly.

Ummmm. Not me especially on a matte surface

No need for power tools.

Sounds like the Dremel may be a little too much.

oil and a piece of brown paper bag will also work

That's an old one but may be the safest. Let the oil work on it for a day first.

Thanks for the suggestions, and what does the brown paper bag do?  is the rougher surface of the paper bag the "sandpaper" so to speak in this example??

If you have rust; you won’t remove it without impacting the finish. Are they Leupold rings?

In a way I guess. The paper isn't abrasive, but it will help rub the rust particles off. The trick is to let some penetrating oil work on the rust for a while to loosen it.

 

You will have a blemish after the rust is gone, the trick is to blend it in to make it less noticeable. On a matte surface that means not polishing with anything abrasive. The 0000 Steel wool has almost no abrasive effect, but it will be more than the paper.

 

Start out slow and work your way up, remove just the rust then blend in the blemish with a little cold blue. I like the oxpho blue because it doesn't need any particularly great cleaning or surface prep. In addition it is a little lighter and can be layered up to get the best match. Several applications will darken it but don't rush the process.

been working on it slowly as suggested and making progress on removing the surface rust.  Thanks .
