I know in the navy you send them for 100yds of Gig Line(which is what the seam of your button shirt and the zipper of your pants and belt buckle are called when they line up). or send thenm to the HazMat Locker(Hazardous Material or Paint Room) for Bulkhead remover. A bulkhead is the term for walls on ships, hence you can't remove them. and i know there are much more but i forget!
