The easiest way we have found to get this off is with a razor blade. First, make sure your piece is cold. Then scrap the burned goo off. If it is in crevices you may need to use a pick or something smaller, the tip of a reason can get in there also sometimes. A solution to not have this happen again is to have a silicon dab mat. To place the Elev8R or dab straw on. You can also use a torch to burn off any of the burned goo. Do this outside as it will give off fumes of the plastic. This is a great way to clean it, just be careful it gets really hot.
