How do you stop the parcel shelf rattling?

To stop the parcel shelf from rattling, first ensure that all items on or around it are secured to prevent movement. You can also use foam or felt pads to cushion the contact points between the shelf and the car interior. Additionally, check the clips or attachments that hold the parcel shelf in place, as tightening or replacing worn-out clips can help minimize rattling. If necessary, using rubber bands or Velcro straps can provide extra stability.
