Can anyone recommend one that works? One of DS1's white school sports tops seems to be slowly turning pale green from being washed with other uniform bits. However, I have a traumatic memory of a favourite pink and white batwing sweater (it was the early 80s) turning yellow and white after I tried to remove a colour run from it, so have The Fear (DS's top has a school crest on it that I'd prefer not to bleach).
