Is it a good idea to use an anti-bacterial soap when you wash your hands?

It is not necessary to use antibacterial hand soap to thoroughly wash your hands. The real way to properly wash your hands is under warm/hot water (hot as in not burning you) with a good amount of soap, washing for at least 20 seconds. (Singing the Happy Birthday song at a normal pace twice is sufficient.) There may be some science to prove that it kills more germs if the soap is antibacterial, however it is based on preference.

I don't recommend the use of anything labeled antibacterial. At best, antibacterial soap is pointless. At worst, it creates superbugs.

First, I'll address the pointlessness. You use the soap and kill the bacteria on your hands. Then five seconds later you start touching stuff: doorhandles, light switches, walls, books, tables, game consoles, stereos, televisions, etc...all of which transfer bacteria onto your hands. You are literally bacteria-free for a span of mere seconds.

Now the superbugs. No soap kills 100% of bacteria. Those that survive do so because they are tolerant to the chemicals in the soap. The survivors multiply rapidly into large populations of bacteria that snicker at your attempts to kill them with antibacterial soap.
