According to the Canadian Pediatric Society here are the four steps to proper hand-washing. I should also add that you wash for about 15-20 seconds, about the same time as it takes to sing the Happy Birthday song.
Four steps to proper hand washing
- Wet your hands under running water.
- Scrub your hands well with soap.
- Rinse your hands under running water.
- Dry your hands with a clean towel.
When water and soap are not available, use premoistened hand wipes or alcohol-based hand rinses. Keep hand rinses out of the reach of children because they may be harmful if swallowed.
