Using the Deltana 6 - inch Solid Brass Number 6 is easy. First, decide where you want to place it, whether it's on your home or business entrance. Then, use the included hardware to install it. Make sure the surface is clean and flat for a proper fit. For outdoor use, it can handle different weather conditions, but if you live in an area with very harsh winters or lots of salt in the air, it might be a good idea to check it regularly for any signs of wear. To maintain its beauty, simply wipe it with a soft, dry cloth. If it gets dirty, you can use a mild soap and water solution, then dry it thoroughly. Avoid using abrasive cleaners as they can scratch the finish.
