I bought something last year that you put in the wash & it removes dye which has run into something it shouldn't. I'd washed my favourite bright pink vest top in with some other colours & a navy top leaked blue streaks all over it, managed to save it with the dye remover though. Hang on I'll just go & see if there's any in the cupboard to get the name....found it, it's by Dylon, Colour Safe Colour Run Remover. I got it from Tesco, give it a go all might not be lost!
