Using this HO scale water crane is easy. Just place it on your model railway layout wherever you need a water - filling station. When handling, be gentle to avoid any damage to the delicate parts. As for maintenance, you can use a soft, dry cloth to wipe off any dust. If the minimal tarnish gets a bit worse over time, you can use a mild brass cleaner. But make sure to test it on a small, hidden area first. Keep it in a dry place to prevent further tarnishing and store it in the original box if possible to protect it from scratches.
