Cleaning UNITRACK:

Kato recommends using a plastic compatible liquid cleaner. For stubborn spots, paint or glue on the rails, we recommend a soft rubberized abrasive “eraser”. Track cleaning cars are also available. Some are designed to use liquid cleaners, some with abrasive rollers or pads, and some equipped for both. We do NOT recommend constant use of abrasives. You can find any of these cleaners and cleaning tools at your local Hobby Shop or Hobby Supplier.

Items not recommended include: sandpaper, steel wool & cleaning pads (used for cleaning pots and pans), and any liquid not compatible with plastic, or is of a caustic chemical compound.
