Using this waste bin is easy. Just open the door with the provided key and dispose of your waste through the opening covered by the self - closing panel. Remember to keep the key in a safe place. For maintenance, regularly clean the stainless - steel surface with a mild cleaner to keep it looking new. Avoid using abrasive materials as they may scratch the finish. If you choose to install it in a recessed way, make sure the wall opening matches the specified dimensions. Also, periodically check the hinge and lock for smooth operation and tighten any loose parts if necessary.
