Using your Bobrick 35303.MBLK Matte Black Napkin Disposal is easy. Just open the self - closing door and place your napkins inside the removable plastic receptacle. When the receptacle is full, simply remove it, empty the contents, and put it back. Make sure to keep the area around the wall opening clean. Avoid using abrasive cleaners on the matte black finish as it may damage the coating. Periodically check the hinges of the door and the self - closing panel to ensure they are working smoothly. If you notice any leaks from the receptacle, inspect it for damage and replace if necessary.
