Okay, I'm completely new to this, but seeing as I've owned my Stargate for three months now, and I'm not sure when it was last cleaned by the previous owner, how exactly should I go about cleaning the playfield? I'm not sure I want to use novus 1 because I'm not sure there's wax on the playfield. Also, is it important I clean the entire playfield, or just where the ball travels? I don't want to tear the entire thing apart unless absolutely necessary. My playfield also has some bubbling mylar, but I'm not concerned about fixing that.
Basically, I just want to know what I need to use and how I need to use it. Thanks for any help!
