Dye Transfer on Clothing

One should never let the item dry out after the dye has spread. Contact Amway... they have 2 product syou can use if you use it while it is still damp, and they really do a great job. The products to use are Amway fabric bleach and Tri-enyme laundry pre-soak and detergent booster.

Doesn't hydrogen peroxide work well for this?

There is a product called Shout Color Catcher Sheets, available in the laundy aisle of the supermarket. Wash the shirt by itself with a few of them and if the shirt has not been through the dryer, the color should be gone. If it has been through the dryer, it may not work. Since the shirt is unwearable as is, give it a try. This product has worked for me.
