what temperature does water need to be for handwashing to be effective? between 90°f and 99°f between 80°f and 89°f there is no minimum temperature required for handwashing to be effective 100°f or more

Explanation:

The effectiveness of handwashing mainly depends on proper technique (such as rubbing hands, covering all surfaces, including between fingers and under nails) and using soap, rather than a specific minimum water temperature. Cold water can also remove dirt and germs effectively as long as the proper hand - washing steps are followed.

There is no minimum temperature required for handwashing to be effective
