Ok I just finished my complete restoration on my Harlem globetrotters back in may and have put in 2 different balls.1 from pinball life and now ninja and both have became rusty in no time at all.none of my other games have this problem at all. How do I remedy this problem. Do I clean or replace the ball trough on harlem or are just pinballs cheaply manufactured nowadays. Please all suggestions are greatly appreciated.
