Using the Bradley BX - 4781 - 11 Sanitary Napkin Disposal is easy. Just open the top hinged cover to place or remove the waxed paper liner. When the liner is full, simply take it out and replace it with a new one. You can order a box of 500 waxed paper liners with part number P11 - 022. Before you install the disposal, make sure to double - check all the rough - in dimensions. Then, use your own mounting screws to secure it to the wall or partition at the provided holes. To keep it in good condition, clean the stainless steel surface regularly with a mild cleaner. Avoid using abrasive materials that could scratch the satin finish. This disposal is built to last, but gentle care will ensure it serves you well for a long time.
