Accidental tie dye

I sent some recently tie dyed burp cloths and onesies through my second wash with my prefolds, workhorses and cloth wipes. They had already been washed and used a few times so I wasn't expecting the color to bleed anymore. But now most of my stash is a nice light shade of pink.

Any suggestions of how to remove the dye? Baby girl doesn't mind but I was planning on reselling my stash after her as it is all in good condition. But it is all pink now.
