Well, what I would try is to rinse/soak 1 skein (in case it ruins it, it's better 1 skein than all of them) in cold water. see if it bleeds too badly. Take it out of the water and place it on a paper towel to dry. Then check out what color the paper towel is when it's dry.
The other thing you could do is to plan on NOT washing your piece when you're done. Work on that one only when you're home and know that your hands are clean as well as the enviroment. I don't bother washing my pieces when I'm done with them. They just don't get dirty.....
Or another things you could do - return the WDW floss to your LNS/ONS and order some floss that IS colorfast...
