The part I was most concerned about was the score reel itself.
These are plastic with screen printed numbers and I was concerned that by cleaning them the numbering would be damaged.
In the end I carefully tried hand soap and water with a toothbrush, this worked very well with no damage to the numbering at all.
The score reels on each end have a circuit board attached to them that I believe is for the match feature??
These were cleaned up with fine steel wool and the wipers cleaned with white spirits.
I had to take note of the re-assemble position of the wipers as it was obvious this did matter.
You can see a small locator on the reel that matches with a notch on the wiper but it is so small that it might be possible to assemble it incorrectly.
