Scientists have created an anti-microbial lining that can wipe out body odor thanks to some sweet-smelling chemicals in wine and chocolate. Researchers at the University of Tokyo say the invention opens the door to making clothes that don’t have to go in the washing machine all the time.

The material zaps underarm sweat, which gives garments a nasty odor. The new coating is a cocktail of silver and plant compounds (polyphenols) called tannins. They are found in many common foods and drinks including tea, coffee, wine, and chocolate.
