Using your custom metal wall art sign is easy! Just decide where you want to hang it. If you asked for hanging holes, use appropriate wall hardware to mount it on your wall. As for maintenance, a gentle wipe with a dry or slightly damp cloth will keep it looking great. Avoid using harsh chemicals or abrasive materials as they can damage the powder - coating. Also, try to keep it away from extreme humidity or direct sunlight for long periods to prevent any fading or rusting. That's all you need to know to enjoy your beautiful metal sign for years to come.
