Here is a well-done video demonstrating proper hand washing technique.
- Rub hands palm-to-palm.
- Rub palms to backs of hands, with fingers interlaced.
- Palm-to-palm with fingers interlaced.
- Fingers curled and interlocked.
- Twist and scrub each thumb.
- Rub fingertips on each opposite palm.
- Rub each wrist.
The WHO has a downloadable, printable version of their recommended hand washing procedure, which is very similar, here.
