I have a white sports band and it looks as though it has taken on some dye from clothing on the edges. It is a green colour. I have tried the above with no success. Any suggestions?

I use an alcohol wipe to clean dye off my white band. Real denim dye seems to make mine blue and green.

I have a total of 3 different colors and they all changed overtime. I wish Apple would create a program where consumers can exchange for the same color if the color change. Those bands are $50 each, I really Apple would do something about it.
