Hand sanitizer?: Are you using hand sanitizer to kill virus on surfaces? From what I have read Dettol antispectic sanitizer is 62 % ethanol alcohol. However it sound like you are markedly diluting the concentration. Have you considered using a product made to clean surfaces that contains 70 percent isopropyl alcohol ? Not all cleaning products kill COVID 19 - I am uncertain if what you are doing is effective.

COVID 19: The alcohol sanitizer which hit your face should not transmit COVID 19 to you. This is not what is meant by aerosolized virus.
