Not sure where I got this understanding, and it could be totally wrong, but I always understood chlorophenols to be a pretty difficult to recover from flaw, hence the extreme importance in making sure you have good water... I don't know that they CAN'T be cleaned up, but they certainly don't easily clean up and sometimes will persist for a very long time. Whereas other phenols can clean up pretty quickly, especially the ones that come across as "smoky."
I also didn't think bandaid was automatically chlorophenol, though.
