KATO Track Cleaning Pad Set of 3 Model Train Maintenance This is a KATO track cleaning pad (Part Number: 001HC001). It's a convenient cleaning tool for wiping away dirt on the tracks. Two are unused. One was used a few times for layout maintenance and washed, but it's still perfectly usable. Recommended for those experiencing poor running performance with their model trains. How to Use: Slightly soak the white part of the pad with the separately sold Uni Cleaner (cleaning solution) and apply it to the axle area of the train. Please purchase only if you understand that this is a used item. #KATO #Kato #NGauge #ModelTrain #RailCleaning #MaintenanceSupplies #UniCleaner
