You could try one of the dye catchers but it may be too late. RIT makes a color remover that works well though. For future reference though Shout, Woolite and Dye Magnet all work great. DYE Magnet is actually a terry cloth looking cloth that can be used over and over (up to 50 washes but I use until it literally is full of holes) and the others are supposed to be one shot uses. However, I have used them more than once with great results. So far.
Unfortunately, I'm having a hard time finding the Dye Magnet anymore. I wrote and e-mailed them once and they actually sent me a free one to shut me up I suppose!
My laundry room wouldn't be the same without one version or another.
