Model train tracks require regular cleaning to keep them in good condition and ensure that the trains run smoothly. White vinegar is a popular and versatile cleaning agent that can be used to remove rust and dirt from the tracks. To use it, simply apply it to a cloth and wipe the tracks dry. For normal cleaning, soaking a paper towel in a liquid cleaner and dragging the cars back and forth on the tracks works well.
When cleaning locomotives, it is important to clean one truck at a time and keep the other truck away from the towel on the tracks to avoid collecting electricity. To clean while you play, you can also make some easy-to-manufacture passive wheel cleaners. A small once-a-week application of these cleaners can help your trains run smoothly on your model railway.
