Using the Custom Metal Dog Sign is easy. You can hang it on a wall in your home, like your living room or bedroom, to show off your love for your dog. To hang it, if you've asked for mounting holes at checkout, simply use nails or screws that fit the holes. If you didn't add holes, you can use wall hooks or adhesive strips. As for maintenance, a simple wipe with a soft, dry cloth is enough to keep it clean. Avoid using harsh chemicals or abrasive materials as they might damage the metal or the paint. Also, try to keep it away from excessive moisture to prevent rusting. If you have any further questions about using or caring for your sign, don't hesitate to message the seller.
