After the corona disaster, the importance of proper use of disinfectants was reaffirmed in the medical field. Some disinfectants used in living organisms cannot be utilized, and some use concentrations differ depending on the indicated site. When treating living organisms, the use of a high concentration of disinfectant may cause a shock if the wound site or mucous membrane is diluted incorrectly and a high concentration of disinfectant is employed. It is necessary to always be aware of the effectiveness of disinfectants and the prevention of side effects. Cleaning is the basis of environmental maintenance at medical institutions, but disinfection is essential in the event of contamination. It must be understood that the method of disinfection of the equipment used for the patient is determined based on the degree of risk of infection at the site of the instrument. Adherence to hand sanitizer for healthcare workers remains one of the key issues for infection control in healthcare facilities. It is desirable to practice reliable hand disinfection at the necessary timing. In this paper, besides the basic knowledge necessary for practicing the proper use of disinfectants for living organisms, equipment and environment, and fingers, we have compiled a systematic understanding of disinfectants based on new knowledge.
