Using this waste receptacle is easy. Just open the door with the provided key and drop your waste inside. The self-closing panel will cover the opening to keep odors in. When it's time to empty the bin, simply open the door and take out the waste. As for maintenance, clean the exterior regularly with a mild soap and water solution to keep the matte black finish looking great. Avoid using abrasive cleaners as they can damage the coating. If you need to mount the bin in a recessed position, remove the skirt before installation. Make sure to measure the wall opening accurately to ensure a proper fit.
