Can the hot water kettle in the hotel be used to boil water? What's the catch?

Many people say that the kettle in the hotel can't be used to boil water. In fact, at first, I was puzzled. What can a hot kettle be used for besides boiling hot water? Later, I learned that it was because many people cooked underwear and socks with hot water bottles in hotels. They sterilize clothes at high temperature in this way. In fact, I didn't believe this kind of thing at first, but many people are saying that someone will do it. This behavior is really immoral, but when you feel at ease, it hurts a lot. We all know that underwear and socks are full of bacteria. Once you cook these things in a hot kettle, the next person, if you don't know this situation, can imagine how dirty the boiling water is. So if you want to drink hot water when you go out, I think it's best to ask the front desk if there is any hot water, or drink a cup of hot water when you eat out. It's best not to use the hot water kettle in the hotel, because we don't know whether this hot water kettle has been used by others to cook anything, so it's better to be careful for safety. In addition, I would like to advise people who cook with hot water kettle that it is not necessary to iron socks and underwear with hot water. Just wash yourself with laundry detergent. Even if you burn yourself with hot water, you can also boil the water with a hot kettle and put it in a basin. There is no need to cook those things in a kettle, because it is convenient for you alone, but it is inconvenient for thousands of other people in Qian Qian. After all, you are not the only one who goes in and out of the hotel. If an old man or a child needs to take medicine, he has to boil water with a hot kettle. But how much hidden trouble will this unclean hot water kettle bring to others? So I hope everyone can understand each other when they go out, have fun without hurting others, and be good to themselves and others. Sometimes it is happier to help others.
