How do I remove a milk stain from my UGGS?

I went grocery shopping today and while I was removing milk from the diary isle, a drop of milk spilled on my brand new UGGS! I wiped it dry and rushed home to clean it with water. I waited until it dried and tried to revive the suede with steam while gently "brushing" it with a toothbrush... It did help; by first looking at it, no one would say there's a stain there; however, I see a darker spot!!! Please help!
