When is 70% isopropyl rubbing alcohol better than 91%?
That makes sense. Are there any specific situations where I should use one over the other?
Yes, if you are disinfecting a surface or an object, 70% isopropyl rubbing alcohol is more effective as it allows more time for the alcohol to denature the proteins of the microorganisms. However, if you are cleaning electronic devices or delicate surfaces, 91% isopropyl rubbing alcohol is better as it evaporates more quickly and is less likely to cause damage.
