Needle files don’t work as well when they get dirty. To clean them, buy a tall, slender jar of olives (your choice), empty it (it’s a tough job but somebody’s got to do it), then fill the jar with lacquer thinner. Put your clogged needle file in the jar and close the lid. After an hour or so, remove the file and clean it off with a stiff brush. It will come clean easily and be ready for your next work session.
