Answer:
The answer is that we should wash our hands frequently with soap or alcohol.
Explanation:
In the "Bacterial Morphology and Staining Techniques", we often observe that bacteria are undeletable with only water. During your staining experiments, the bacteria stick well to the slide. The only way to wash away the bacterial sample is using ethanol.
From the results, we know that washing hand with only water is not efficient. We have to you detergent such as soap, ethanol, propanolol, etc.
