So.. Nasty Problem

I got a purse for Christmas last year. I want to start carrying it again. Problem is, in March I put an orange in my purse to eat at lunch . Forgetting all about it and quit carrying my purse to work I left it in my purse for months. I know nasty! I didn’t touch my purse for a long time until I brought a smaller one. When I went to clean it out I found the orange left in there. I about died in tears . So how would I get the mold from the orange out of my purse ?
