Using the Bobrick B - 353 is easy. Just open the door with the tumbler lock, lift the self - closing panel, and place your sanitary napkins or tampons in the removable plastic receptacle. When the receptacle is full, simply remove it, empty it, and put it back. Remember to keep the unit locked to maintain privacy and security. For maintenance, clean the stainless - steel surface regularly with a mild cleaner to keep it looking great. Check the self - closing panel to ensure it's working properly. If there are any issues with the tumbler lock, contact a professional for repair.
