I bought this purse quite awhile ago at my church yard sale...I love it, but its somewhat dirty. It has a few stains; how can I remove them without damaging the purse? Thanks in advance! you can see it used to have a strap (it wasn't a shoulder strap though) but it was half off when i bought it then fell off completely. i don't know where it is now, i can't imagine i would've thrown it away.
