Using this Bobrick disposal unit is easy. Simply open the self - closing panel, place your sanitary napkins or tampons inside the removable plastic receptacle, and then let the panel close on its own. When the receptacle is full, just remove it, empty the waste, and put it back. As for maintenance, wipe the satin - finish stainless steel surface regularly with a soft, damp cloth to keep it looking good. Avoid using abrasive cleaners as they may scratch the surface. When installing, make sure to measure the wall opening accurately according to the given dimensions to ensure a proper fit.
