Reply to comment by regular_modern_girl in Why does alcohol kill bacteria, but not the cells that our bodies are composed of? by Chairman_Mittens

Stealing the top post to add:

If you are cut, you are better off NOT disinfecting with alcohol since the alcohol will kill the cells at the edge of the cut and slow healing. You should wash with soapy water.

Also for bacteria, the most lethal concentration of alcohol is about 70%. This kills more bacteria than the 99%.

Not that soapy water won't also do some killing, but it should be on a smaller scale.
