    I use some Autosol or Flitz on a rag if I want to remove/reduce patina.

    Thanks for all the suggestions everyone!

    I heard that some stuff can actually scratch the blade or mess up the finish somehow. Which ones should I be aware of, and any other tips as to not cause myself grief?

    I just tried using Steel Glo. Not much patina on my knives, but had some light rusty bits and this did very well. Bought this a few years ago in Malaysia and forgot about it, but obviously still works. It's a US product so should be available for you. Also it claims to be non-toxic which is a plus.

    I would start with BKF on the end of a wine cork or a metal polish like Flitz, Metal-Glo or Nevr-Dull wadding. ScotchBrite, both the green and brown, may put fine scratches on a blade, at least in my experience.

    Patina cleaning test

    I was curious enough to do a short test of the three methods that were suggested: BKF with a cork, BKF with a ScotchBrite pad and a metal polish, in this case Metal-Glo.







    The sacrificial lamb was a Harner O1 cleaver. This is how it looked pre-test:



    I soaked a paper towel in vinegar and laid it on the blade for five minutes. Instant patina.



    Then I cleaned three swaths, from top to bottom, Metal-Glo on a paper towel; BKF on a wine cork; BKF with a new ScotchBrite pad.







    I was a bit surprised to see that the metal polish did the best job. The fine scratch pattern that the ScotchBrite pad left is easily seen.

    Rick, this is more than I could ever ask for in a reply. Thanks so much!

    Certainly the scratches are very visible. I was always hesitant using scotch brites, because if makers use them to create a finish, than using one to clean up a knife would certainly alter the finish, wouldn't it? Maybe it's a certain type of scotch brite, or technique, or something.

    That metal polish looks fantastic, and I'll have to go get some.
