Great question actually! Alchohol has a denaturalising effect on cell proteins. Bacterial cells are made differerent from ours, so with the right concentration in water (70% is considered ideal), the alcohol penetrates into the bacteria and only attacks our outer layers which turn hard and prevent further damage.
