For years, I have looked for a solution to get the godawful persistent funk out of dry-fit athletic shirts. My shirts get so vile mid-workout that even I can't stand the smell of me, and god help any tennis friends stuck in a car with me on the way home. I found that putting Oxyclean into the wash helps, and the clothing smells OK afterward. But the funk returns like the grim reaper the next time I wear it. I tried pricey sports detergents like WIN. Febreeze sports detergent. Vinegar. Cold wash. Hot wash. Double wash. Double rinse. Putting them in the freezer. Borax. Oxyclean. Chlorox 2. Some things helped a little, but I was thinking of throwing out all my shirts and starting over. Well, I cracked the code. My new laundry routine for dri-fit shirts is: Put hot water into a small bin or bucket just large enough to hold the items. Add a crazy amount of Oxyclean (2+ heaping scoops). While that dissolves, hand wash the items in warm water and laundry soap. Rinse the clothes in the sink, then put them into the Oxyclean cauldron and stir. Let them sit there for a day or overnight, giving it a stir whenever you are in the vicinity. Remove from the Oxyclean solution and launder as usual; air dry. As I type this, I am wearing a dry-fit shirt after having done a hard, sweaty workout. I swear, it smells perfectly fine. So far, I have only done this with inexpensive shirts -- I can't risk any Lululemon leggings that cost $$$. Since I was on the verge of throwing the shirts out, it was worth the risk. I'm not seeing any ill effects in the fabric so far. You have no idea how the quality of my life will improve now that I don't have to worry about reeking athletic clothing. No longer will unlucky bystanders wonder whether I have adopted a skunk. Now I need to do some testing and gradually reduce the amount of Oxyclean until I find a suitable ratio.
