Milk baths

Hi Mummies! I have a stash of milk from April that I want to use for milk baths. I have some questions to seek help from you ladies! 1) As thawed milk have a metallic fishy smell, I’m wondering if my baby will come out smelling like that? ? And may I also know if you guys 2) put soap into the milk bath? & 3) rinse baby with just water after soaking her in milk? Thanks in advance! ???
