What are your best tips on cleaning stains from a white convertible top?

Lots of birds (mostly seagulls, aka flying rats) around the parking lot at my workplace = almost guaranteed bird poo on the top at the end of the day.

Thanks.

 

Purple power or Westley's bleech white....and a scrub brush.

 

I would go easy on the Bleechy White it's a caustic chemical...Magic Earser worked very good on my top, it's cheap disposable and you don't have to wax your car when your done
