"Shirt Soup" Stain Remover...even removes stains that have been set by the dryer. Boil water in a big pot on the stove. When it comes to a boil, turn off the heat, add some OxyClean, and add the garment. You can use a big soup pot and put in a few things or a large garment, or small pot for just a little garment. Let it soak until the water is cold, or overnight, and pour the whole thing into the next load of laundry. If this doesn’t get the stain out, nothing will.
