Article: If you want, you can wash even longer. 20-30 seconds is the rule of thumb so that you'll wash long enough to get rid of the germs. If the water does not automatically shut off, then hold onto the faucet with your towel to turn it off. That way, you don’t re-contaminate your hands right away. Throw away the towel if it’s disposable or hang it to dry.  You can also use your elbow to turn off the faucet if a towel is not available.  If you’re using reusable hand towels, wash them at least every 2 or 3 days so germs don’t build up.
