Mold in diaper bag

A bottle had spilled in the bottom of my diaper bag and I didn’t use it for a few days so I didn’t know and now the bag has mold in the bottom of it. I washed it in the washing machine and it’s still there. Is there anything I can do to clean it or should I just throw it away and buy another one? If there’s no way to clean it I’d rather just throw it away than risk my daughter getting sick
