My Kung-Fu specialty is the two section staff (Dai so ji). I noticed rececently that the three rings connecting the sections has some sort of grime (Not rust) and seems looser. Is this a problem? If so, how do I treat it?
Edit: I am afraid I lack pictures of the problem. However, I can provide an explanation. The staff has seen a great deal of usage. The grime is black and bumpy to the touch. When I perform a large swing it always feels as though it will fly off, though the it doesn't look damaged or loose, just grimy. If the problem cannot be solved, I am open to purchasing a new staff.
