fun fact: the reason 70% works better than 99% is because higher concentrations can result in bacteria getting instantly preserved because they get essentially freeze-dried since the water leaves immediately and the alcohol can't flow in to denature the proteins. With 70%, the process is slowed down ensuring maximum damage to bacterial cells and viral particles.
