Had to explain how iso alcohol is a poor disinfectant earlier today and I'm still mad about it.

Depends on what the concentration is, IIRC. 70% is better than 90%.

Iirc, the higher water content keeps the alcohol from evaporating off as fast, keeping it in contact with the surface for a longer period of time.
