Micron pens

I have never used the Micron Pigma Pens on cloth before, unfortunately for me, the one time I've done so, when I tried to wash it out, it's run and also run into some white applique next to it. A quilt friend suggested pouring boiling water from a distance and letting it run through. This has worked somewhat. I've also used Oxyclean spray on it and the red remains on the white cloth (applique) next to the marking with a soft pink blush. I've never used them before and I will not use them again on cloth. Any suggestions in removing it entirely. It says it's water and fade proof and they aren't kidding.
