Cry over a spilled latte?

I got in my car after work tonight and noticed a distinct smell of coffee...a smell I love...but then it hit me.  My mother-in-law spilled an entire grande latte in my car on Sunday.  My husband tried to clean it up, but I have a feeling that after a few warm summer days, the milk is not going to be a smell I love!  Gotta get my steam cleaner out!!
