Yes. Black powder really grimes up the cases but it should not hurt them chemically.

Hit the nail on the head. Even a mild acid can leach the cases. I had several that looked a bit reddish after cleaning an unknown spill off them. I tried an experiment. Pliers to crimp the case mouth, except the case didn't crimp as it should, instead it broke and tore. I chunked the whole lot since they were no longer the right stuff.
