I have had success cleaning threads by using home-made split dies or chasers. If you have a spare nut of the correct thread, cut through the side of the nut so that it can be levered open slightly or closed up, depending on what you need to do. Then case harden it with Casemite or whatever is available. This approach is no use for cutting new threads, but with care, is useful for cleaning up burred or damaged threads.
