Food safe cleaning wipes?

I live in a dorm and have a coffee mug and a few cups that i continually use it's a hassle to go to the bathroom and clean them up and most of the time it doesn't get very clean i'm wondering if there are any food safe cleaning wipes like those clorox ones.|||use wet ones. safe on baby's.|||Wash the dishes in a better quality detergent than the cheap crap you are buying. Pour a bit of bleach in the cups and swish it around. Stains will disappear.
