Using the Fender Jack Rack is super easy. First, use the provided wall - mounting kit to attach it to your desired wall. Then, simply hang your keys on the real guitar plugs that come as keychains. For maintenance, keep it away from excessive moisture and direct sunlight to avoid damage to the materials like the amp grill cloth and the brushed metal logo. If it gets dirty, you can gently wipe it with a dry cloth. Also, be careful when handling the keychains as the guitar plugs can be a bit delicate. Don't force them too much to prevent breakage.
