When is 70% isopropyl rubbing alcohol better than 91%?
That's interesting. Does it mean 91% isopropyl rubbing alcohol is always better for disinfecting?
Not necessarily. 91% isopropyl rubbing alcohol can be better for disinfecting when you need it to evaporate swiftly, such as when cleaning electronic devices. The higher concentration of alcohol in 91% solutions evaporates faster, leaving a dry surface behind. However, 91% isopropyl rubbing alcohol is not the best option for sterilization.
