The proper sequence for washing hands is essential to ensure effective removal of dirt, germs, and other contaminants. The correct steps begin with wetting the hands thoroughly under clean running water, as this prepares the skin for the application of soap. Following this, lathering the soap is crucial; it helps to lift dirt and microbes from the skin.

Next, scrubbing the hands for at least 20 seconds is vital as this is the phase where friction aids in dislodging any remaining particles and pathogens. After scrubbing, rinsing the hands under running water effectively washes away the soap along with the loosened dirt and germs. Lastly, drying the hands with a clean towel or air dryer helps to further reduce the number of germs, as wet hands can transfer bacteria more easily.

This sequence (wet, lather, scrub, rinse, dry) ensures thorough cleansing, enhancing hygiene and minimizing the risk of spreading infections. Other sequences provided may not prioritize the necessary steps effectively, leading to potential oversight in the handwashing process.
