I have had this happen more than a few times .... you can actually fix it. Lay your choc streaked fondant out and wipe down with damp Viva paper towel or a new damp chux/or cloth. It will make your fondant a tad wetter just re knead and and let it sit for a little before re trying. If you really can't get it all off just knead it and set aside for when you require coloured fondant for another order.
