WOW - that's one dirty game, and a huge challenge that you are breezing through. Great to see the kids involved. You are doing the right thing by checking the electrical wiring. That would be my biggest concern due to the game's history. Playfield looks fantastic after cleaning. Maybe all the poop provided a protective covering ?

Video has some very cool background music. Underrated album - "Hollow Years" is a epic song. I often listen to DT while doing long hours.
