I used to clean and wax and new balls once a year. I have stopped waxing clear coated games. I clean at the very least once a year with novus 1. Star Wars has been getting tons of play so I have cleaned it like 3 times already since March when I got it NIB. Balls every year or so or when they look suspect. I still wax my EMs and would wax any game without clear coat or that has wear.
