Someone spilled hot choclate on my daughter's jacket at school today. The jacket is 95% cotton, 5% spandex, and is a cream color, but has tan and brown embroidery, so it can't be bleached. The chocolate stains are in several different places on the jacket.

I pretreated with laundry detergent and washed it, but stains were still quite noticeable. For the past 4 hours it has soaked in water with a full capful of laundry detergent and oxy clean. Stains are somewhat lighter but still noticeable. Any ideas what I can try next?
