Using your metal house number sign is a breeze. First, decide where you want to hang it - it can be indoors or outdoors. For outdoor use, make sure the area is dry and protected from extreme weather. To hang it, simply use the pre - drilled holes on the sign and a nail or screw. When it comes to maintenance, a simple wipe with a damp cloth will keep it looking great. Avoid using abrasive cleaners as they can damage the powder coating. If the sign gets wet, dry it off to prevent rusting. Enjoy your unique nautical house number for years to come!
