White metal, zinc, pewter, all of these metals are very soft and tend to clog files, especially needles files or rifflers. You can try using a wire brush but if the metal is really stuck to the teeth you might have to get a sharp probe and just pick it out. It's not as hard as it sounds. When you get them clean here's a trick that I was taught as an apprentice patternmaker. Get some ordinary chalk, like the kind that is used on a blackboard, and lightly rub it onto the file before you start filing. The file will still cut but the chalk will prevent the chips from sticking to the teeth. I hope this helps.
