My poor JD needs some work. It was my first pin when I knew nothing at all about repair and maintenance. I've been force fed the repair part and now JD is playing good, but the game is very dirty. When I wipe my finger on the pf or a ramp it comes away with dirt on it. So I've been reading a lot on here about cleaning products and mostly people use Novus. Would this be the best for the diamond pf or should I use something like Simple Green? Originally I was going to just use a rag and clean around things but more and more I'm thinking of clearing the playfield. I'm not the most handy handy guy in the world so I'm a little afraid that I won't put the playfield back together correctly. Plus, I have some broken plastics that maybe will break more. This game doesn't look the easiest to take apart. I was also thinking of putting in LEDs. It looks kind of dark and gloomy next to my other pins. Would it be easier to just clean and led it out at the same time? Thx.
