How do you carry stains out of a depressing suede jacket? The problem is I don't know what the stain is! :S

Answers:    You take it to a leather specialist cleaner. That's not for amateurs...especially if you don't know what cause it. That's going to hamper their usefulness as well, if you can't share them what they are trying to remove. Either toss it, or take it to a pro. Good luck, sweetie!
