Is the dirty bag of washing machine useful?

Is the dirty bag of washing machine useful? The answer is: a dirty belt will definitely help. I don't know if anyone has tried to open the hotel sheets or quilt the mattress inside. Trust me, you want to run away from the hotel immediately after reading it. Nowadays, hotels can change sheets every day, which can isolate bacteria and viruses, because bacteria and viruses are not animals and will not climb out of the mattress. For a person who loves to travel and travels frequently, I can give you some advice: 1, bring your own water cup, toothpaste toothbrush, towel, shower gel and so on. And don't use hotel towels, bath towels and shower gel (not to mention possible pollution, poor quality is also a big reason); 2. Bring some fresh-keeping bags and paper. Paper is used to separate the direct contact between the remote control and the door handle. Fresh-keeping bags are used for sleeping clothes. Very convenient and necessary; 3. Bring hand sanitizer or antibacterial hand sanitizer, and be sure to wash your hands often when staying in the hotel; 4. Try not to touch other items in the hotel;
