in the season of flu and so many other germs, we're told again and again that hand sanitizers and soap are the best defense. Last year American government spend over million dollars on hand sanitizers alone.  So we wondered what were the best and how did  hand sanitizers compare the showdown  with the soap? Tonight doctorXXX puts them to test and get some real answers.

cleaning?as many as 400 thousand germs on each hand. that's how many bacteria travel with us every day.so .......6 brave grad students and I volunteered dust hands in a toxic brew with thousands of ecoli bacteria.Yep,ecoli.

to see what would take off, first step, hands in the ...we tested two kinds to find the ..one with 60% alcohol, and one so-called natural fomula containing no alcohol.
the key with hand sanitizers is to use enoughly. you hands should take a full of fifty seconds or longer to dry.
now let that air dry ok?
then we place our hands on a special ....place to grow any remaining bacteria.
the results :dramatic.
those green spots are the ecoli from unwashed hands. after, using sanitizer with 60% alcohol.
But the fomular without alcohol?look how many germs left behind.
alcohol based sanitizer works so much better because alcohol breaks bacteria's protein and kills them.
But you really want to get clean? What is the best of all? Guess what? itls our old friend -- soap.
soap not only does well on bacteria as sanitizer, it gets more ...,too. Surprings, study shows that the anti-bacteria and regular soap are equally affective. but how you use is crucial. most of us just spend 5 seconds on the sink.just look  how many germs remain? yerk!
you have to wash your hands for full 20 seconds to get the bug ...and yes,that's singing happybirthday twice.
so let's rebuild again:
hand sanitizers began get to sink, but look for one with at least 60% alcohol. But wash with soap, any kind is better, as long as you wash long enough.
Something that little odd about raving equal, too see what to take off, first up hand sanitizers. We   chose  two kinds of and find this all. One with 60% of alcohol, and one so-called natural formula containing no alcohol, the key with hand sanitizers is to use a naffibin. You hand should take up a bowl 15.2 too longer to dry. Now let that air dry ok? Then we press our hands to special incubation plates to grow any remaining bacteria. The results dramatic. Here those green sparks to the equal eye, the crew for unwashed hands, after using hands hand sanitizer with 60% alcohol, but the formula without alcohol, just look how many germ behind.

Alcohol based sanitizer works so much better, because alcohol breaks the bacteria’s proteins and kills them. But if you really want to get clean, what’s you best of all? Guess what? It’s your old friend, soap, soap not only gets it well on bacteria and sanitizer, it gets more viruses too. Surprisingly, study show regular and inter-bacteria soap, now equally affected. But how you use it it is crucial.
Just look how many germs remain.You have to wash your hands for 20 seconds to really get the bulks off.That's singing Happy Birthday twice.So let's review it again.

So we wondered what works best and how do the sanitizers compare in a showdown with soap? Well, tonight our chief medical editor Dr. Richard Besser puts them to the test and gets some real answers.

Clean? As many as 400,000 germs per hand, that’s how many bacteria travel with us every day. So you are  at the University of Maryland Food Safety Lab, six brave graduate students and I voluntarily dust our hands in a toxic brew, the thousands of ecoli  bacteria. Yeah, ecoli.

“Good? Something a little odd about rubbing ecoli.”

Just to see what would take it off.

First up, hands sanitizers. We tested two kinds you’ll find at the store: one with 60% alcohol, and on so-called natural formula containing no alcohol. The key with hand sanitizers is to use enough of it. Your hands should take a full 15 seconds or longer to dry.

“Now let that air dry, ok?”

Then we pressed our hands onto special incubation plates to grow any remaining bacteria. The result? Dramatic. Here, those green spots are the ecoli that grew from unwashed hands. After, using hand sanitizer with 60% alcohol. But the formula without alcohol? Just look how many germs left behind.

Alcohol based sanitizers work so much better because alcohol breaks up the bacteria’s proteins and kills them. But if you really want to get clean, what’s your best of all? Guess what? It’s your old friend –- soap.

Soap not only does as well on bacteria as the sanitizer, it gets more viruses too. Surprisingly, studies show regular and antibacterial soap are about equally effective. But how you use it is crucial.

“Go!”

Most of us only spend five seconds at the sink.

“Stop!”

Just look how many germs remain. Yuk!

“Go!”

You have to wash your hands for a full twenty seconds to really get the bugs off. And yeah, that’s singing “Happy Birthday” twice.

So let’s rebuild again. Hand sanitizers if you can’t get to a sink. Look for one with at least 60% alcohol, but washing with soap -- any kind -- is better, as long as you wash for long enough.
