You can use exit mould.
If you just spray it on and leave it it will leave a big bleached patch on the clothes so you need to spray a bit on then give it a quick rub and rinse it before it starts bleaching the clothes. Then repeat and repeat and repeat until all the mould is gone. I did this with a $120 shirt I couldn't bear to throw out and it worked a treat.
If the uniform is white you might be able to get away with a little less rinse and repeat.
If anyone knows a less tiresome way I would love to hear it.
