Both alcohol and hand sanitizer can be effective in killing germs and bacteria on the hands. However, the effectiveness of each option can depend on various factors such as the concentration of alcohol or active ingredients in hand sanitizer, the type of germs or bacteria present, and the amount of time spent rubbing the hands together.
Alcohol-based hand sanitizers typically contain at least 60% alcohol, which is effective at killing many types of germs and bacteria. Hand sanitizer is also convenient and easy to use, making it a popular choice for quick hand cleaning on the go. However, it may not be as effective as soap and water in removing dirt or certain types of bacteria.
On the other hand, washing hands with soap and water for at least 20 seconds is generally considered the most effective way to remove germs and bacteria from the hands. Soap can break down the structure of the germs, while the friction from rubbing the hands together can physically remove them. However, soap and water may not always be available, especially when you are out and about.
In general, using alcohol-based hand sanitizer is a good option for quick hand cleaning when soap and water are not available. However, it is important to note that hand sanitizer should not be used as a substitute for hand washing with soap and water, especially if your hands are visibly dirty or if you have been in contact with someone who is sick
