Cleaning moldy coffee cups

I know that the porcerlin cups don't ever need to be cleaned since old coffee just hardens and becomes part of the device. However, I've noticed that if I leave a travel cup in the car for a few days, the cup gets a funky, moldy type smell that highly influences the taste of ensuing cups of joe. I have tried conventional means to cleanse these cups but to no avail. Do I need to replace these now nasty travel mugs or is there a way to cleans the funk from within?

TIA,
 
My thoughts:
1) Throw out the moldy cups. Are you that cheap that you'll drink mold just to keep a cup?
2) Bleach will do the trick. Be sure to rinse it well, since bleach residue isn't something I'd want to drink.
3) Washing the cups will prevent the mold. Is there any reason you feel cups shouldn't be washed?
 
Thanks, no, I DO believe that cups sh0ould be washed, however, sometimes they don't always make it out of the car and into the house.
 
ordinarily i'd just say hand scrub and run through a dishwasher, but i don't think it'll come out. and drinking something that just had been bleached sounds gross to me.

just toss it and get a new one. next time, clean daily.
 
uhh... It's just mold.

Soap will take care of it.

Unless we're talking about plastic cups, in which case the smell may never come out if it's sat for weeks and weeks. If that's the case, you'll just have to get new ones.
