Cleaning ball marks on playfield?

[Replay]

I use Novus 2 on playfield but not sure how to get black lines out i.e where the ball runs? I don't want to rub too hard in case I take the varnish off? Any tips?

Try Magic Eraser soaked in a bit of white spirit or lighter fluid. Bear in mind that this combination can be quite abrasive so go carefully. I wouldn't advise this on non Diamond Plate/Stealth Coat playfields - you will lose the paint quite quickly otherwise. If this doesn't shift it - you can try a rotory polisher or drill polisher attachment.
