Iodophor disinfection and alcohol disinfection have the following differences: 1. Both are medium-acting disinfectants, iodophor is characterized by the formation of unstable bonds by combining with bacteria, viruses and other surfactants, while alcohol is disinfected by denaturing the relevant proteins. 2. Both have different disinfection scopes, iodophor has better disinfection characteristics and has disinfection effects for various microorganisms. 3. 75% alcohol can be used for disinfection 4. Alcohol disinfection quickly evaporates and is somewhat flammable. iodophor disinfection requires re-application of sterile cotton swabs or it will remain on the surface of the disinfected object.
