  • To be effective against killing some types of germs, hand sanitizers need to have a strength of at least 60% alcohol and be used when hands are not visibly dirty or greasy.
  • Do not rely on “Do It Yourself” or “DIY” recipes based solely on essential oils or formulated without correct compounding practices.
  • Do not use hand sanitizer to disinfect frequently touched surfaces and objects. See CDC’s information for cleaning and sanitizing your home.
