Satan's ball point pen

[Rail26]

I had a ball point pen accident by my possessed pen. There I was on my way to work for an early morning flight. I opened up my door and there are ball point pen marks all over the door leather. My pen click itself open, poked through the side pocket of my flight suit and wrote all over the side of my door. I thought for sure it said "redrum'. Anyway, I used the Sonus leather cleaner I had and that did not even lighten the pen. I need something a little more heavy duty for the exorcism of the blue pen besides a catholic priest and holy water. I am afraid to get too medieval on it because I don't want to wreck the leather...Any suggestions?

If I offended any Catholics I apologize, but I just watched the "Exorcist".
