Is the bathtub in the hotel sanitary?

When I was a freshman, I heard a story told by a friend who was a nurse. A couple has a pair of lovely twin daughters. At that time, my two daughters were only seven or eight years old, and my father worked as a manager in a star-rated hotel. One day, the eldest daughter went to the hotel to play. The little girl looked at the beautiful bathtub and clamored for a bath in it. At that time, the staff thought it had been cleaned and was very sanitary, so they assured the little girl to take a bath in the bathtub and then went to do her own thing. Half an hour later, dad looked everywhere for his eldest daughter, and then the staff remembered that the little girl was still in the bathtub. After half a month, the little girl always caught a cold and complained about her lower body discomfort. Her mother took her to the hospital to see the children's department. At that time, the doctor asked her to take her daughter to gynecological examination. At that time, her mother wondered, how old is her daughter? How to do gynecological examination? Doubt is doubt, but it's okay to listen to the doctor. After the gynecologist checked, she told the little girl that she had gonorrhea, syphilis, condyloma acuminatum and chancre, and asked if anyone in their family had ever had a sexually transmitted disease. . My mother's first thought was to suspect that her husband was fooling around outside. A small bathtub in the hotel almost destroyed a family, which is worth pondering, especially the hotel staff. Did you do a good job of disinfection when cleaning the bathtub? I found on the internet that it is better to clean the bathtub with neutral detergent or soap and water. Avoid using cleaning agents on ceramic tiles or enamel surfaces, and it is best to clean them once a week to ensure that the bathtub remains dry after each use. Use a neutral liquid cleaner and clean the bathtub with a soft cloth or a quality sponge. Corrosive cleaner staying on acrylic surface will cause damage. Clean the acrylic surface thoroughly after each use, and don't let the detergent enter the circulation system. Do not leave the container filled with liquid detergent on the surface of the bathtub for a long time, and do not use spray or concentrated solution or other similar cleaning products. Don't leave metal objects in the bathtub, they will rust the bathtub and dirty the surface. In addition, the effect of sharp control disinfection solution to eliminate dirt is also good.
