When it comes to workout clothes, one caveat of getting a good sweat on is that the fabric can hold onto both moisture and odor. Chlorine bleach is one way to freshen clothes, but many fabrics aren’t designed for bleach, and it’s not the greenest option either. After you wash your workout clothes, consider hanging them out to dry on a very hot, bright day. A dry, hot day can do wonders to deodorize clothing; the sun’s natural UV rays and ozone can kill odor-causing bacteria. If the day is even slightly humid, the technique won’t work; in fact, it can just encourage additional bacterial growth on the clothing instead.
