recently had an ink pen break in my car, before I knew it I had ink EVERYWHERE, door panels, seats, hands, clothes, every where I looked I had ink. Alcohol wouldn't touch it neither would vodka. lol I was miles from home. I went to NAPA, an auto parts store, and they sold me a bottle of cleaner that works on leather and fabric items. Can't remember the name but it worked like magic, cleaned the car, me, my clothes, leather coat and everything it touched. Had a slight lemony odor for a while but it worked. Try an auto parts store, they can help.
