In Hand Washing, Technique More Important Than Technology

10/29/09 - Good Morning America did a segment of handwashing

They actually rubbed their hands with E Coli and used either soap or hand sanitizer to see which worked better


"The first thing we noticed is that alcohol-based hand sanitizer clearly works the best. In fact, the CDC says you should use a hand sanitizer containing at least 60 percent alcohol. " The most popular product on the market is Purell, which has 62% alcohol.

"As for soap, the antibacterial soap worked only slightly better than the regular soap."

"The Food and Drug Administration recommends using only regular soap because of worries that germs will develop resistance, and people will develop laziness from high-tech soap. Based on the results that we got, it's really not necessary to use antimicrobials in the products. You can see some difference, but it's really not significant"
