Using your custom metal Halloween sign is a breeze. Just find a nice spot indoors or outdoors, use the pre - cut holes to hang it up with a nail or hook. When it comes to maintenance, a simple wipe with a soft, dry cloth can keep it looking great. Avoid using harsh chemicals or abrasive materials as they may damage the powder - coat finish. If you live in an area with extreme weather, you might want to bring the sign indoors during very harsh conditions to make sure it lasts a long time. That's all there is to it! Enjoy your spooky sign this Halloween.
