Step-by-step explanation:
Yes, you still need to wash your hands even if you use hand sanitizer. While hand sanitizers are effective in killing many types of germs, they are not as effective at removing dirt, grime, and certain types of bacteria.
Hand sanitizers are most effective when used on clean hands. So, if your hands are visibly dirty or greasy, it's important to wash them with soap and water first. After washing your hands, you can then use hand sanitizer to further reduce the risk of germs.
Furthermore, handwashing with soap and water is still considered the best way to remove and eliminate germs. Hand sanitizer should be used as a supplement to handwashing, especially when soap and water are not readily available.
