Rubbing alcohol

Depending on what kind of germs you’re trying to kill, 70 percent alcohol is probably more effective than 91 percent for disinfecting.

A 90 percent alcohol solution is too powerful in some cases. It kills the outside of the cell before it can get into the inside and kill the actual germ.

Alcohol percentages

  • To fend off bacteria, a 70 percent alcohol solution with water in it allows it to cross a cell membrane and kills the entire cell.
  • Viruses with an envelope structure, including the new virus, can be deactivated by alcohol solutions of 60 percent.
  • Any concentration of alcohol won't effectively target the norovirus.
