Does anyone have any information about hand sanitizers like Purell or Calstat damaging rings? I've heard people say that it can weaken prongs or cause discoloration but haven't been able to find any real information online. I asked my jeweler if I need to worry about my platinum rings and they said that I shouldn't. Does anyone have any information or personal experience with their rings being damaged by these products? And yes, I know many people think rings should be left at home because they harbor bacteria, can scratch patients, won't get damaged, etc.
