I don't know what to do anymore. :C

I thought maybe getting a bandeau to cover it up would be fine, but I really don't like acessorizing it all the time. Can someone help me find a way to lighten up this staining? What happened was it was a bit dirty because I placed it down at a park. My mistake! So I thought I should take some nail polish to remove it. Totally ruined me bag, sigh. I read some threads and the only thing seems like I can only lighten the staining.

I have no idea what steps or product is needed. Can you help me? I might just buy the bag again if nothing can be helped.
