Using the Deltana 4 - Foot Solid Brass Number 7 is easy. Just find a suitable spot on your home or business building to display your address, like near the front door. Make sure the surface is clean and dry before installation. For maintenance, use a soft, dry cloth to wipe it regularly to keep its shine. Avoid using harsh chemicals or abrasive cleaners as they can damage the brass finish. If it gets dirty, a mild soap and water solution can be used, but be sure to dry it thoroughly afterwards. This way, your number will stay looking great for a long time.
