To use your metal heart wall art, simply find a suitable spot on your wall and hang it up. It's great for adding a decorative touch to any room. When hanging, make sure to use appropriate wall - hanging hardware based on the size of your sign. As for maintenance, you can clean it with a soft, dry cloth to keep it looking its best. Avoid using harsh chemicals or abrasive materials as they may damage the powder - coated finish. If the sign is placed outdoors, be aware that extreme weather conditions might affect it over time. In case of heavy rain or snow, it's a good idea to bring it inside or cover it. Enjoy your beautiful wall art!
