Can the kettle in the hotel be ironed before use?

When boiling water in a hot kettle in a hotel, it is best to fill it with water and boil it continuously, then pour it out and use it to boil water. Boiling water has the function of sterilization. A hot kettle boiled in boiling water for three or four times can be used to boil water. Of course, if you don't have to, you'd better not use the hotel hot water kettle to boil water. After all, I don't often live outside. Occasionally stay in a hotel, just buy a few bottles of mineral water for later use.
