I have developed my own modification to the standard hand-washing technique you’ve seen on YouTube and in GIFs, which I believe will be beneficial (although I am not a medical professional):

In addition to turning off the faucets with the towel, to avoid contamination, also use the towel to open the bathroom door and turn out the lights. This further avoids touching contaminated surfaces.

Then go out in the living room and let the dog lick your hand.
