Keep the cleaning time to a minimum so as not to irritate your passengers. I use the squeegee with minimal juice from the bucket and in the evening Invisible Glass with a cotton kitchen towel on the windshield and side windows.
Quick Detailer and micro-fiber works well to take the bugs off the front if they are not too severe. Otherwise Bug and Tar Remover with micro-fiber followed by Quick Detailer and a clean micro-fiber.
