SOS: Spoiled Milk in my Purse 😫😢

Kristina • Loving Mother. 2 year old baby girl. Baby boy due in March 2016. Happily taken since 9-2010!
Okay so this isn't really "baby" related. But I need to know what I can do for my coach purse. My daughter decided it would be a good idea to put a cup of milk in my purse. Well come to find out that cup of milk was old, and well it exploded.😭 all over my purse and coach wallet. I'm so sad. I've tried getting the stench out with dish soap, leather cleaner, and even a little tide mixed with water and it won't come out. 
Does anyone have advice on how to get the smell out? It's an all black purse and wallet; so I am scared to use anything on it in fear it'll fade the black. 
Please help!
