Alcohol is a very good chemical disinfectant for killing and sterilizing, and the best concentration for killing and sterilizing is 75%. The main difference between medical alcohol and industrial alcohol is that medical alcohol has a higher purity, while industrial alcohol may have other chemical components in addition to alcohol. As far as the concentration of alcohol itself is concerned, if it reaches 75%, even if it is industrial alcohol, it can play the role of killing and sterilizing. Therefore, it is possible to use industrial alcohol to clean and sterilize the surface of objects in life. Content source: Dr. You Lai
