I've seen quite a few threads specifying unscented bleach, but haven't seen any that give a reason for this. What is in scented bleach that would cause problems? Would the additives used to provide the scent not dissipate just like the chlorine, or would they instead build up over time (similar to CYA?) and start to become a problem after long-term use? Is there a short-term problem with scented bleach? Suppose that through lack of foresight or whatever the only bleach I have on hand is scented, and I need to add chlorine before I have a chance to get to the store? Would that really be a problem?
I don't have any particular reason to use scented bleach, I'm just curious.
