Please help - favourite white cotton top was put in a hot wash and didn't realize something red was in there too so everything went pink. Have since put it through again twice with the colour run rescue liquid stuff and it has faded but still visibly pinkish with the non-cotton trim now standing out as a lovely pale grey.
What is the best next step? Wash as normal? Or bleach? And if it is bleach, what do I do exactly?
