Do any of you "tin platers" have suggestions on how to preserve old AF or Lionel rails? I clean them up but they just start oxidizing again. Thought about cleaning them up, and then spraying them with matt fixitive. Would then clean off the top and inside of the rails so i'd get good electrical contact. Also, what can you put on the old switches, and other plastic parts, to clean and shine them up again? I forget what this plastic was called. Very brittle and thick, early plastic radios werre made out of it too. I have just been using dish detergent and a toothbrush for most of my cleaning chores. Use "GOO-GONE" for the tough stuff. Also, again, If the rail is rusty, after you clean off the rust, is there anything you can coat the metal with to maintain good electrical conductance?
