I know that doing the same with simple green could destroy the chain, but how safe are mineral spirits on metals?

And on the same note: how clean does the chain actually has to be for the paraffin to actually do a good job? I've already been through three 12-hours baths of MS and the chain still leaves some black residues on a white rag. Is the matte coating of my ultegra chain supposed to come off?
