Re: mold spots?
Yes, bleach! And leaving things wrapped up in a plastic bag is never good. If she is a frequent care giver, I would let her know so it doesn't happen again, if she feels compelled to rinse, it doesn't need to be wrapped in plastic (which kind of defeats the point of not using plastic diapers!) but needs air circulation. The stains won't go away but bleach will prevent it from getting worse.
