baby bottle help.

breast feeding mom
I have really expensive bottles. I was cleaning babies room and I look over at his end table and see a bottle curdled! I totally forgot about it and the milk must of been in there for about three days. I can't get the smell out of the bottle. Is there anything I can put in there to help the smell? I really don't want to throw it away. (A 2 pack cost 23.49)
