During handwashing, how long should you scrub your hands?

• A. 1 minute
• B. 20–30 seconds
• C. 5 seconds
• D. 10–15 seconds

Answer: (D)

The main idea is that you need enough scrubbing time for soap and friction to reach and lift germs from every part of your hands. Thorough contact with soap, plus rubbing all surfaces—palms, backs of hands, between fingers, and under the nails—removes more microbes than a quick rinse.

Scrubbing for about 10 to 15 seconds hits that balance: it’s long enough to clean effectively but practical enough to do quickly in a busy setting. If you go only a few seconds, you won’t dislodge as many germs; if you wash for a minute, you’re likely to be less efficient and may irritate skin with excessive washing. After scrubbing, rinse under running water and dry with a disposable towel, using the towel to turn off the faucet to prevent recontamination.

So, scrubbing for 10–15 seconds provides enough time to remove germs while staying practical for everyday cleaning in food service.
