My sun faded grande seems to have hit a sweet spot and now looks pretty cool (photos and video coming soon...), but there are quite a few lava "smears" in the globe that I'd love to get rid of if possible. I'd rather not take the top of though as I really don't want to risk stuffing it up... does anyone know if there's a way to get these marks off at all? You can see one on the right hand side of the attached photo. Thanks!
