DD's tshirt came back from nursery with lovely black speckles on it that look a bit like mildew - we think she must have got changed twice in a day and the tshirt got shoved down to the bottom of the bag in its little nappy bag, thus making a nice damp atmosphere for yuk to grow in.
I've tried cleaning it with stain remover and a 60 degree wash, but no luck so far. Any other ideas, or is it just a goner?
