Things You'll Need
Instructions
Remove a train car from the track and lay it on its side.
Spray light oil onto a cotton swab. Gently rub the dirty areas with the damp swab to break up residue. Wipe away any excess grime that breaks off with a clean cotton swab.
Coat a utility knife with light oil, and gently pick at harder grime deposits or layers of residue. Be patient and deliberate to avoid damaging the train piece. After removing a chunk of grime, try to clean the rest away with a cotton swab coated in light oil to see if the utility knife is no longer necessary.
Coat a non-metallic kitchen scouring pad with light oil and rub the pad along the train tracks to remove any dirty spots. You can also use a utility knife to remove particularly stubborn grime.
Wipe all surfaces clean with a fresh cloth after cleaning is complete.
