Which of the following is NOT a method of sanitation?

Sanitation methods are processes aimed at maintaining cleanliness and reducing the presence of pathogens. Washing hands with soap, using bleach to disinfect, and boiling instruments are all recognized methods of sanitation.

Washing hands with soap effectively removes dirt, pathogens, and organic material from the skin, thus preventing the spread of infection. Using bleach for disinfection involves applying a solution that can kill a wide range of microorganisms, making it a powerful sanitation method for surfaces and equipment. Boiling instruments sterilizes them through the application of high temperatures, ensuring the elimination of bacteria and viruses.

Applying moisturizer to the skin does not play a role in sanitation. While moisturizing can improve skin health and hydration, it does not contribute to the reduction of pathogens or cleanliness. Therefore, it stands out as the option that does not fit within the context of sanitation methods.
