I use a quick Novus 1, followed up by a light Novus 2, then wax in the most heavy use areas ( the ones I can reach) My DE SW played so fast this week that it messed up the ramp switch and put a ball into the bottom of the cabinet. I guess off the ramp somehow. Waxing does help and a little Novus to clean up ball tracks and in between pop bumpers can't hurt too much. Home use only, I would use some Novus 1 if I saw tracks and wax it every so often. My games get a ton of use and I have to clean them every few days. I think that for most people light cleaning should be fine for a new game. I would be more concerned with ball drops off the ramps and ball kick out areas. Those do much more harm than general playfield play/wear. Games will get dirty and wear if you are playing them. That just means you are having fun with them! As intended.

Since ACDC has the clear coat over the lower playfield, you might want to wax that more often and be careful about using an abrasive on it. I don't think there is a way to remove that window without putting in a new playfield. I would say Novus 1 and wax on the window and no Novus 2. That's just my opinion.
