I see dealers listing daggers saying,” blade has some smudge that may clean up”.They know it wont,tried it before and the blade always looked worse than when I started.Once its there its there, from improper handling,storage whatever.I will never buy a dagger again that has “smudge”,a better name for it is plating loss and rust ! Maybe if its a himmler ss,might be able to live with a little smudge.Anyone had any luck cleaning these dagger blades?Tried Fitz,semi chrome,and mothers on an army and gave up.Live and learn.
