HELP... Iron on transfer minor disaster!

[tbandemommy]

Can someone help me please? I have made 25 iron-on shirts. All but 2 turned out great. I washed inside out and dried them and took them out of the dryer immediately after the cycle ended. The images on 2 shirts bled through to the back of the shirt. Is there any removal/cleaning technique to get the transfer ink out of the back of the shirt. I would try a bleach pen, but these shirts are yellow and pink. Any suggestions would be GREATLY appreciated. We leave in 12 days.
