Soap can be dirty. Bar soap is often host to many germs depending on its environment. Liquid soap is cleaner, but avoid soap with "anti-bacterial" ingredients as they're both ineffective and, in aggregate, contradictory. Chances are most of you just grab the door handle with wet hands and re-apply a lot of what you washed off, then go touching your family's faces, so don't sweat using the right soap if your ignorance is that significant.
