I just had a problem with red ink. Not on a quilt but on a double faced satin ribbon I was using to make sashes for flower girls. Don't have a clue where the ink came from or what type of ink it was. It just appeared on the front of one of the sashes. I used a clorox pen, which didn't work and then I used a white cloth dampened and a drop of (blue container) Dawn. This worked and the ink was totally removed.
