I have just done a coloureds wash including - amongst other items - my daughter's purple trousers, my son's games top (reversible blue/white with white collar) and a towel.
The trousers have leaked purple dye. Oddly, the only things that are affected are the back of the towel - which used to be white - and the collar of the games top - the main body is still perfectly ok. Everything else is also perfectly ok.
I have tried soaking and re-washing with Vanish to no avail. Any other ideas, please?
