Many of today’s high-tech fabrics are designed to wick sweat away from your skin, absorbing moisture and keeping you dry. The problem is these sweat-wicking fabrics lock in the stink, too. Regular laundry detergent is formulated for lightly soiled cotton-based fabrics, and cannot effectively get the odor out of your stinky socks, smelly shoes, sweat-stained shirt, etc. The only thing that can get your smelly clothes fresh is a sports detergent specifically formulated to eliminate the sweat left in the clothing that causes odors. 2Toms Stink Free Sports Detergent works because it eliminates the sweat that is left behind. It even works on today’s high-tech fabrics that hold on to odor after they’ve been washed with regular laundry detergent.
