if you look in the washing detergent aisle at the supermarket, there are bottles of clothing bleach, my fave brand is white king, that stuff works on anything, i use all thier cleaning products. however, even home brand basic bleach does the job. you can either put it through your wash cycle, or soak it in bleach and water. soaking works brilliantly, for some reason, we get a lot of mould here, and bleach gets the mould out of clothes when you soak them, and leaves the clothing really white. if you have mould on coloured clothes, there are some colour-safe bleaches around. just have a look through your cleaning aisle and you'll find some. hth
