Things You'll Need
Instructions
Apply a small amount of denatured alcohol or isopropyl to a clean cloth. Denatured alcohol is a stronger alcohol and will remove tougher buildup, but it will remove paint or varnish. Isopropyl alcohol is gentler and will not damage painted surfaces.
Rub the cloth over the tracks to remove most of the dirt and debris.
Dip an old toothbrush into the alcohol. Scrub the tracks with the toothbrush to get all of the dirt in the track's crevices.
Run the train over the tracks when they are still wet with alcohol. This will help spread the alcohol to clean the tracks as well as the model train wheels.Let the alcohol try completely on the tracks.
