Sometimes it helps to thread 'em in the backside of the arm to clean 'em up.
This is either a joke or just really questionable advice. "A lot of force" is what leads to "I stripped my vintage crankset". If your threads are tight (or French) - they should be cleaned up with a tap. That extra material in there is just as likely to make the threads blow out as anything else.
