Anyone know how to get tomato soup out of baby clothes?

This week at nursery, Immie has decided she doesn't want the staff to feed her, she wants to feed herself. Great, heading towards another milestone.

All sounds fab, except this week they decided to feed her tomato soup. She came home in her emergency change of clothes and with soup in her hair. Apparently the soup went everywhere during her bid for independence.

I've tried washing at 50 instead of 40 and using a stain remover in the wash but I'm admitting defeat, her vest is still covered in orange stains. Anyone know how to get tomato soup out of baby clothes?
