7 Healthcast: Hand sanitizer vs. hand washing

So what works best, hand washing or sanitizing gels?

"Hand washing. Hand washing is better. Every study I see shows that it's preferred," says pediatrician Dr. Larry Scherzer.

Even the company that makes Purell says gel like is is not meant to replace hand washing.

Dr. Scherzer says if gel is all you have, make sure it's at least 60 percent alcohol and apply it liberally.

I should take a few seconds to dry on your hands.

Dr. Scherzer notes sanitizing gels it won't remove dirt on hands or under nails, which a thorough hand washing will do.

The Centers for Disease Control says hand hygiene is the single most important means of preventing the spread of infection.
