Ironing StainI need information on how to clean a 100% cotton blouse that was ironed with an iron that was too hot. The blouse is white with these instructions: "Machine wash separately in cold water. Use non-chlorine bleach only when necessary. Tumble dry low, warm iron. A friend ironed an item of clothing, then ironed my blouse, not observing the instructions. Can anyone tell me how to get the black stain out?
