Are you able to get Ivory bar soap(not liquid)? For many, many years I have used it to remove stains. You wet the item with water, rub with the bar of soap and wash as usual. You can leave the soap in the item and just wait to wash. It doesn't hurt the item to have the soap dry on it. Takes out just about any stain, including ballpoint ink and is especially good on grease. Occasionally you have to use it twice to fully get a stain out.
