Color Bleeding Stain Removal
To remove stains caused from dyes leeching from one article of clothing to another, you can purchase a product that is designed specifically for this purpose. It is called Rit Dye Fabric Treatment - Powder Color Remover and is available everywhere that you can buy fabric dyes. Soak in the color remover, then launder as usual.

Good Luck! =)
