I was cooking pork-chops in my kitchen when the oil bubbled and splattered on my grey cotton-strchy zip-up jacket, and my jeans. I have not washed them yet, i didnt want to set a stain. however, i forgot about them in the back of my closet for a month or so, which i dont know, but im guessing it makes it much harder to get out?!?! Does anyone have any suggestions before I attempt this, or is it stained for life?
