- Using baking soda helps. Pre-soak your clothes in a solution of water and Arm and Hammer Super Washing Soda (or just use water and a cup of baking soda). You can use the pre-soak setting on the washing machine or do it in a separate container. Then wash and use Arm and Hammer laundry detergent.
- Try using a special detergent formulated for technical wear, such as WIN sports detergent.
In addition, there are lots of new odor-fighting running clothes on the market. Although they may sound too good to be true, these running clothes do actually help keep you dry and odor-free. Although some of them are a bit pricier than your average running shirts, it's worth the investment because they'll last longer and keep you smelling fresh!
