Kinda futile I think, but I found a late '70s/early '80s Diane Von Furstenberg jumpsuit with a tiger pattern and bought it for 8 bucks. (out of my range, but I liked it) When I got it home I realized that there were some marks on it that are very hard and stiff. It made the fabric a touch darker. I tried to remove it with lighter fuel, but that didn't work. I'm wondering if there is any way to get this stuff off. Anything I might try? Thanks!!!
