You might have mistook rinsing your hands for washing in the past. Washing your hands isn't only about wetting your hands after they get dirty or after visiting a bathroom.
It should always go with soap. Another tip; splashing soap on your hands is not doing anything, instead it serves as drink for the microbes on the palm of your hands. It is the sustained scrubbing action and foaming that cleanses off microbes.
Scrub the soap on your palm for a few seconds, and rinse off with clean running water. That way, washing the palm becomes effective. We shouldn't wait for an endemic before observing this health tip. 91% Isopropyl works like magic, too. A topic for another day.
