Just dunk them in lye solution (OUTDOORS!) 'til clean/ the gassing stops!
If you're set up for electrolytic rust removal, connect them as if you were removing rust from them and it will do the job also, without damaging the files or your skin. Sodium Carbonate, or washing soda, is caustic, but not nearly as strong as Lye. It will also remove paint, oil, and grease.
