OK,
Two photos below are area in question. The first (area near ball lane armature) was a bit of concern. I found a bit of a crack through timber as I guess the constant thumping / movement of the arm has caused this. Might be an idea for other T2 owners to check too.
You can see the marks / dirt I am talking about. I have gone over with ME quite hard without value.
So ME does not lift the dirt - it looks to have created a "track".
On older machines without clearcoats, I roll some 800 grit around the skinny end of an old billiard cue and "sand away" the dirt. But I would not recommend this for your game. It looks like the dirt in the upper section is embedded in the cracks of the clearcoat ?
