OK. So I am occasionally messy. Margarine loves my sweatshirts. It loves my sweatshirts so much that it jumps on my sweatshirts when I am not looking and then it refuses to go away. Oxy clean, Dawn, Goo Gone, Shout, etc are defeated by margarine. If anyone has successfully removed margarine from a sweatshirt, I would appreciate knowing how they were successful. Thanks, Steve
