If it's a white shirt I pour bleach directly on the mold nad let it sit for several hours (usually overnight but thats because I forget about it and don't remember about it for a while) and then I was it. It sometimes takes 2 times of doing that but it does come out. Unfortunately I do it all the time with the pool clothes and when he plays outside and gets wet. If its a color item I use either Shout or Spray N Wash and let it sit for overnight again. It does come out. I've done it a lot and it works every time. Good luck.
