Help - Schoolbag smells like sour milk

I would have suggested vinegar, spray on and leave to dry...

This happened with DD's daycare and insulated lunch bag. I just put them through the washing machine with normal laundry detergent. No probs! I do have a policy in my house that if it can't go in the dishwasher of washing machine it goes out. My single mum survivor instinct.
