Using your Deltana 6 - foot Solid Brass Numeral 3 is easy. Just find a suitable spot on your home or business exterior where it can be easily seen. You can use appropriate hardware to mount it securely. As for maintenance, simply wipe it with a soft, dry cloth regularly to keep it looking its best. Avoid using abrasive cleaners as they might scratch the brass finish. Also, make sure to check the mounting hardware occasionally to ensure it remains tight and secure. If it's exposed to harsh weather conditions, a light coating of brass polish can help protect it and maintain its shine.
