on your hands.
we need to rub our hands together with soap and water long enough for the soap to do its job. we need to allow enough time for the soap to make foam, lift the oil holding onto the germs, and rinse them all away.
how long is long enough? try singing the happy birthday song as you rub the soap and water between your hands, especially rubbing the soap and water over your fingers and fingernails where germs love to live. if you get through the whole song, you are giving the soap long enough to do its important job.
don’t forget to rub your hands on a clean towel
