Prior to any committed pinball machine repair I finished the first initial cleaning to get an idea of how the game will look. The amount of grime that came off was pretty impressive.
I still need to decide if I want to do any touch-ups at this point cosmetically or not. I’m inclined to just apply wax to it at this point and let it be, and come back to this in the future. The cosmetic issues on the playfield are not as important as dealing with the switch and battery issues.
