Cleaning Moldy Tracks

[js]

I inherited a set of N guage tracks, presumably nickel from the 60s, but they have white mold on them from being in an old house for many years. Does anyone have any tips for how to get rid of the mold without destroying the tracks?

Are you sure it's mold and not mildew?  Mold usually needs a food source, whereas mildew just kind of covers things.

First thing I'd try is soak all the sections in water with detergent for a couple of days, toothbrush it thoroughly, and then rinse with clean water.

If that doesn't work, Spray with isopropyl alcohol from the drugstore and let it set a while, Toothbrush it off, and then rinse with water.  I would test this method on one piece of track first to make sure it doesn't affect the plastic adversely.

One thing everyone forgets is the rail joiners. I would plan on replacing them, you'll never get them clean up inside and you'll never have good contact.  And don't forget to really clean the Underside of the rail where the joiners go.
