Alcohol with a concentration of 75% can successfully absorb the water of bacteria and virus proteins, denature and solidify them, thus sterilizing and inactivating them.
In the absence of 75% medical alcohol, cotton balls can be dipped in highly alcoholic liquor (above 60 degrees) to temporarily wipe the surfaces of door handles, keys and other objects, or used for skin disinfection. In addition to buying medical alcohol in pharmacies for direct use, there are also some hand-free disinfection gels and alcohol disinfection wipes containing 75% alcohol for daily use.
