I had the same problem too. What I did was take hot boiling water and scraped with scissors and what wouldn't come off, I had to cut top layer off. Best wishes

Have you tried using "Goo-Gone"? I have found this product to be amazing! It breaks down glue, paint, all types of things. I would try just a little bit on a small part of the stain and see if this doesn't help. You can get "Goo-Gone" at any hardware store (Lowes, Home Depot)
