If all else fails, try Clorax Stain Buster and Color Booster. It will not bleach the colors and I have found it removes anything I have tried it on. It will be labor intensive, but better than ruining the quilt. I dampen the stained item and put the Stain Buster/Color Booster directly on the stain, let it sit for 10-15 mins., then wash. My GGD has written on her shirts/pants with everything that can make a mark plus all the pizza sauce, etc. that she spills on herself.
