As many of you know I'm involved with the Allentown shows. We do O gauge train races that are very popular with the kids. The track is traditional O gauge tubular mainly because it's relatively inexpensive, readily available and pretty much anything the kids can bring to race will run on it. The layout gets used heavily on train show weekends but otherwise gets stored in an unheated garage for the rest of the year. Obviously this can lead to rusty track and other problems associated with storing tubular steel track in non-climate controlled spaces.
Two years ago I began wiping the track down with Lemon Pledge the furniture polish before breaking it down and sending it to the storage garage. I take an old t-shirt and spray the Pledge on it then wipe down the track cleaning and buffing it as I go. I keep the rag fairly damp so the liquid helps to clean. You can see how much dirt accumulates when you wipe it. It even cleans off dirt, residue from many derailments and shines things up rather nicely. The track has been coming back not only clean but still shiny. When we set it up it only needs a quick wipe with a rag to get the dust and it's ready to go. It really works!
I thought I'd share with with others who may find it useful.
