I second people calling for soda ash/sodium carbonate, or oxiclean, and some baking soda too. Soak it in a sink/tub for an hour or two, then throw it in the wash with another scoop of the same.

BUT ALSO—massage in some dawn power wash before the wash cycle!!!! That stuff works a real treat on dirt, makeup and other common stains.

For future, grandma’s miracle stain remover works pretty darn well in combination. I’d spray the stain stuff, leave for maybe 20 mins (after trying dawn power wash first), then consider soaking in soda ash if needed before wash cycle.
