I saw some info (on another site), about cleaning Ninco track, (which is what I have). They recommended to not use any chemicals on the plastic, at all. The track has a rough surface, and they said to only run cars fitted with rubber tires to allow the rubber, to build on the track. For that reason, they said it's best, to only vacuum Ninco track, and to use alcohol, (or other electrical contact cleaner, or somebody even suggested WD 40), to clean the rails. They recommended that this be done every 2 weeks. I did the rail cleaning "thing" this morning, and man, did it need it!
What about the rest of you folks? Any track cleaning ideas and/or rituals?
