So I have a confession. I sweat...A LOT. I was finding that I would wash all my workout/running clothes and they would STILL smell....I over heard a friend (J) talking about Super Washing Soda:
You use your normal laundry detergent PLUS washing Soda. We have a newer front loading system so there are spots for liquid soap (our regular stuff) and powder...we mix both together and voila! Super Clean, No STINK running clothes! As Martha Stewart would say: It's a good thing!
