Sorry but that doesn't look to be the most reputable of sites, more like a cheap sales site for some company.

Here's something from Harvard Medical:

Soap and water don't kill germs; they work by mechanically removing them from your hands. Running water by itself does a pretty good job of germ removal, but soap increases the overall effectiveness by pulling unwanted material off the skin and into the water.
and an article from The Atlantic that discusses use of just water, with soap, and antibacterial soap. It seems proper scrubbing technique (mostly time spent) is the most important factor in removing bacteria:

regular soap simply causes bacteria to loosen their grip on your hands, to be rinsed away
About the gf, let's try to stay on topic. Happy birthday MFauli!
