Using these custom metal house numbers is easy. Just decide on the font, size, and finish you like, and place your order. If you need mounting holes, don't forget to leave a note at checkout. When you receive the numbers, you can use common tools to mount them on your home's exterior. For maintenance, simply wipe them with a soft, dry cloth regularly to keep them clean and shiny. Avoid using abrasive cleaners as they may damage the finish. Also, keep them away from sharp objects to prevent scratches. That way, your house numbers will look great for a long time.
