An infectious disease expert says people do not need to wash out their office coffee cup every day as long as they don’t’ share the mug or leave cream and sugar at the bottom for an extended period of time.
I have a coffee mug that has not been washed out for 20 years. I broke my first one.
My dad was like that, had a mug from his ship in WWII, hadn't washed it in 30 years, then one day mom scrubbed it out.
Dad calmly explained it cures the mug and the coffee never tastes bitter, then threw it in the trash.
Yeah, he was pissed.
