Soap and warm water are best. Next best, scrubbing with plain warm water. People who use sanitizers tended to have more bacteria of more varieties. There was an article in Science News some years ago.

Sanitizers are all very well, but they do not remove the dead skin and dirt which bacteria thrive on. Soap & water will leave your hands with nothing to attract bacteria in the first place.

Sanitisers have been shown to be ineffective against Norovirus for example.

Just returned from a festival gig. Nice loos but no running water so sanitisers everywhere. Yuk! They leave your hands so sticky that playing bass or guitar becomes a chore instead of a pleasure. After the first set I took some ice from the bar to wash the goo off but I still haven't got all the muck off the instruments. 

There may not be any actual loss of tactile performance at the day job, but just feeling uncomfortable can only be a distraction in clinical work, and if the stuff doesn't work anyway, it's surely time to reinstate carbolic soap.

this is asking the wrong question.
The competition isn't "sanitiser vs soap", it's very often "sanitiser vs nothing because they were in too much of a hurry."
So, re "Which is more effective, Soap or Sanitizer and why?" the answer is likely to be the sanitiser- because people actually use it.

Had a freind who broke her hand and decided to use hand sanitizer instead of soap and water to wash her hands, she came down with a severe case of botulism. Point taken however, it depends on how it is used. Still...

Hand Sanitizer. It kills 99.99% of germs, while no one knows how much germs soap does.

Plus, it's a quicker way to wash your hands.

yes they do.
http://www.ncbi.nlm.nih.gov/pubmed/19715426
Warm water and soap removes about 99% in the experiments they did.
this one (different bug)
http://www.ncbi.nlm.nih.gov/pubmed/21219752
indicates that hand washing removes near 99.9%

Soap is judged, clinically, to be the superior method of hand cleansing; it removes the bulk of microorganisms. Alcohol hand rub is convenient, but less effective. It works by killing alcohol-sensitive microbial agents, but that means that alcohol-resistant forms, which includes any non-enveloped virus like enterovirus, noro, or adenovirus, are left intact and unharmed on the skin. This is why doctors urge hand washing with soap and water as the gold-standard practice. The downside of soap and water is that, with regular use, such as in the workplace, the repeated washing of the skin with soaps frequently leads to skin drying and cracking and a dermatitis; the open lesions on the skin then become an infection risk in their own right.

I recently went on an ocean cruise. They had hand sanitiser at the restaurants, and "hand-cleaning police" to (politely) make sure you used it.

People quickly got used to using it, although I noticed a few cases where the language barrier meant that the message was not received.

Its a pity that hand sanitiser does not kill norovirus, since that is a major scourge on ocean liners.
