Always follow the manufacturer's instructions for use. |
| 4. What should you do if your hands are visibly dirty or greasy? | Wash with soap and water | Hand sanitizers may not be effective if your hands are visibly dirty or greasy. In such cases, it's best to wash your hands with soap and water for at least 20 seconds. |

The "5 Moments for Hand Hygiene" approach is recommended by the World Health Organization. |
The Science Behind Handwashing
Handwashing works by physically removing germs from your hands. Soap molecules surround and break apart the fatty outer layer of germs, making it easier for them to be rinsed away. This process is called "emulsification." Additionally, soap can inactivate some viruses and bacteria by denaturing their proteins, making them unable to replicate or cause infection.
Tips for Effective Handwashing
- Wet your hands with clean, running water (warm or cold)
- Turn off the tap and apply soap
- Lather your hands by rubbing them together with the soap
- Scrub all surfaces of your hands, including between your fingers and under your nails, for at least 20 seconds
- Rinse your hands well under clean, running water
- Dry your hands using a clean towel or air dry them
