1. A liquid discharging device, comprising:
a head configured to eject liquid from a nozzle which is an opening in a nozzle surface of the head;
a cap configured to abut against the nozzle surface at a covered position and to separate from the nozzle surface in a retracted position;
a first wiper configured to wipe the nozzle surface;
a discharge channel connecting an internal space of the cap to an outside of the cap;
a controller;
a tank storing the second maintenance liquid; and
a supply channel configured to supply the second maintenance liquid from the tank to the internal space of the cap,
wherein the controller executes:
a first maintenance process in which a first maintenance liquid is brought into contact with the cap in the retracted position and the first wiper;
a second maintenance process in which a second maintenance liquid different from the first maintenance liquid is distributed to the internal space of the cap and the discharge channel, and
wherein the second maintenance liquid is supplied to the internal space of the cap through the supply channel to flow out of the discharge channel.
