Anyone have a tried and true trick for removing tomato sauce stains from plastic? My LOs had sauce on their lunch noodles for the first time today and their high chairs are now covered in orange stains. Their faces are also stained orange, but I assume that will fade in time. Maybe by the time they are 5? My usual hand washing of their high chair trays didn't do anything for the staining, so I thought I'd see if anyone had recommendations. Vinegar? Baking soda? (Uh, not at the same time, obviously) They eat off these (obviously) So I'd like something not very chemical-y. Tell me what you do!
