I just finished derusting some plane irons. Many have a dull dark gray appearance and some mild pitting. I have quite of bit of them to do. On other parts, I would sand them down and then move up the grit to 400-500. This method, however, removes the pits and the engravings.
I would like to keep the engravings and I don't mind the pitting. I want to bring the surface to a reasonable shine quickly. I tried polishing compounds and buffing wheels, but they seem to only turn the dull gray into shiny gray. I tried emery compound and a sisal wheel, but it didn't do much better and the sisal kept tattering up on the edges.
I added some photos of some plane irons FYI.

Whire brush on a bench grinder is my first choise or a twsted cup brush on an angle grinder , will put a polish on cast iron and steel the quickest .
The oxidation seems a little deep to remove with a light abrasive. Even if you use electrolysis it will remove the rust but could leave some pit marks. I think the best you can do is use a soft metal wire wheel then go up in grades with buffing wax. You could just go around the engraving! :coffee:
You could etch them a little deeper couldn't you?
A bit of paint on the top and use salt water on the logos?
Electric rust removal ?
Electric plating, like nickel ?
