If you are using Plum in a second home and it will go unused for a long period of time, you should prepare your Plum by first running the cleaning cycle in both chambers. This is done by going into Settings > General > Clean if your Plum isn't requesting from the main menu. After, opening the door and unplug your Plum. Leave the door open for 12-24 hours to let any condensation dry. Then wipe down your Plum, close the door, and store in a cool, dry place.
