How long should I wash my hands?
It is generally recommended to wash your hands for at least 20 seconds, as too short a time may not be enough to wash them completely.
From the current study, washing hands for 15-20 seconds can remove more bacteria. As a result, many countries and global organizations recommend washing hands for 20 seconds, with some adding another 20-30 seconds to dry hands.
In this process, you should fully rub your hands according to the steps of the "seven-step handwashing method", paying special attention to washing the palms, back, fingers, especially fingernails.

Do I have to use hand sanitizer or soap to wash my hands?
Handwashing with running water and hand sanitizer or soap is more effective than washing hands with water alone.
First, the surfactants in hand sanitizer remove dirt and microorganisms from the skin.
Secondly, rubbing bubbles will prompt us to rub our hands more thoroughly, helping to remove bacteria more thoroughly.
In addition, the friction of the hands during rubbing removes dirt, grease and microorganisms.
Can hand sanitizer replace handwashing?
Using hand sanitizer is effective without running water and hand sanitizer. However, it is not a complete replacement for hand washing.
Washing your hands with running water and hand sanitizer can remove dirt, grease, and most bacteria and viruses more thoroughly, as well as some chemicals such as pesticides and heavy metals.
Hand sanitizer should be seen as a temporary alternative rather than a regular handwashing method. Where available, running water and hand sanitizer are preferred.
In daily life, let us all actively develop the small habit of washing hands correctly to help the health of the whole society!
