Once I got the pin open, I decided to clean some of the playfield to see what lay under all the grime.
I am really pleased with the way it cleaned up. I only spent five minutes with some Novus 2 but the dirt lifted beautifully and the colours came through as you can see below. I probably won't spend much more time cleaning until I do the full strip down but I do find it very satisfying to remove grime!
I still haven't found any wear on the playfield except for near the E N T drop targets. This area is always susceptible to damage. As previously mentioned though, I am not too concerned as I intend to add a 'Cliffy' protector here anyway. The protector will cover the area and prevent further damage.
Tomorrow I will be taking some 1000 grit sandpaper to the wireforms to see how they clean up. A lot of this rust seems to look at lot worse than it actually is. I am hoping that they'll clean up ok without having to be replated. I still intend to get everything gold plated but if they clean up to my satisfaction I may delay the gold treatment.
