Add 50ml of water and sterilize the lid, nozzle, and water tank in boiling water.
For a 700W microwave oven, it's done in 1 minute (based on Elite Fly water tank).
Some people say to use the water tank for one season and then throw it away,
but they also say that if it is not physically damaged, you can manage it well and use it for a long time.
Be careful as other water tanks may be damaged…
