Spilt baby milk in my expensive handbag!!!!

[Azra12]

Evening all. I've just realised I've left a bottle of baby milk in my handbag and its left a massive patch and stinks!!
What can I do to clear the patch and try and get rid of the smell?! (Its a lovely big handbag which I use as an alternative to a changing bag when I'm out with the baby)
Any advice would be greatly appreciated.
Thanks in advance guys

Vanish oxy, leave on for 20 mins then sponge off, then maybe flash/dettol, sponge off and then febreeze and leave to dry in the air. Fixed milkshake on an expensive jacket
