Using this waste bin is easy. Just open the locked door with the provided key, put your waste through the self - closing panel, and then close the door. When it's time to empty, unlock it again and take out the waste. Remember to keep the key in a safe place. For maintenance, regularly wipe the stainless - steel surface with a mild cleaner to keep its satin finish. Check the hinge and the door - swing limiter periodically to make sure they're working well. If you choose to use the recessed mounting option, carefully remove the skirt and follow the standard installation procedures.
