While your method might be absolutely perfect, it's always a good idea to test for residual silver and that's the only way to be sure about it. Even leaving the lights on will not reveal potential problems. I know it, because I've tried toning prints that "looked" properly fixed. It resulted in stained borders and ruined highlights; that was a lesson I learned early...
