Hey Terri, i just asked hubby, he's a mechanic, but worked in a dry cleaners when he was younger. He says wd40 will put an oil stain on the quilt, and gee, hope the peanut butter didnt do that too. Anyways, his trick that he uses around our home is this, for stubborn stains on clothing, he uses brake cleaner that you can pick up in an auto store. He says it is the same chemical that dry cleaners use. He says he doesnt know if that will work for sticky, but worth a shot, and if that doesnt work, take it to a dry cleaners, and they can use a steamer to undo the glue, and then dry clean it, hope this helps :) Ooops, be sure to test the brake cleaner on just a small spot to start with, but it's never ruined any of our clothes.
