Using this sanitary napkin and tampon disposal is easy. Simply open the door with the tumbler lock, and place your items inside. The self - closing panel will automatically cover the opening after use. Make sure to empty the 1.2 - gal (4.6 - L) plastic receptacle regularly to avoid overflow. When cleaning, use a mild soap and a soft cloth on the satin - finish stainless steel. Avoid using abrasive cleaners that could scratch the surface. Check the tumbler lock occasionally to ensure it's working properly. If you need to replace the receptacle, it can be easily removed and a new one inserted. Also, make sure the wall opening dimensions match the specified 11 1/4' W, 15 5/8' H, and 4' min depth for proper installation.
