Hi Tony.
When we were talking at Kettering on Saturday, you mentioned that many of the locos brought to your clinic just needed a good clean of wheels and pick-ups and a drop of oil.
In addition to LB, you have been associated with many large layouts with associated locomotive collections, and rightly expect a high standard of reliable running. What have you found to the best methods of cleaning track, wheels and pick-ups? (and maybe Seep turnout motors!).
