How do I maintain a white convertible top?

Ditto on the bird poop

Seriously, as long as the car will not sit outside or see any real weather, and will not be driven on a daily basis, I don't think you'll need to do anything more than routine cleaning. Over the course of many years, it will develop a certain patina, but that's a good thing in my mind. My 69 Chevelle still has the original white top and it really does have patina.
