Even though I haven't had babies in our family for years, I've always kept Dreft Baby Laundry Detergent on hand for stubborn stains. Not only is this product formulated for food stains but also the stains you are referring to. I prefer the powder. It's very pricey though. Had a pleasant scent as well. I am currently out of it and need to buy a new supply. Sometimes if you go to a laundry mat you may be able to buy a small box of it in a vending machine. If you don't want to buy such a large supply.
One more suggestion, for future drips and to prevent stains, Stayfree Ultra Thin Maxi Overnight pads offer protection in the very back of your underwear. Recently, Always came out with their own XL or Overnight thin pads as well. Both are a real comfort if you want extra protection but don't need to wear something such as Depends.
