There are always so many birds around that poop on my car. I need to do something about them.

You might be plagued by birds due to an abundance of bird feeders and birdseed in your yard. Consider removing birdfeeders for a period of time, and if possible clean your car regularly. It’s also a good idea to remove any bird nesting materials or structures. In addition there are certain products you can use to discourage birds from landing or nesting on your car, including screens and aerosol sprays.
