Warmer or colder - that don't matter
Get your hands wet with clean running water

Now apply soap - liquid or tablet
Lather it up, both the front and the back

Between all the fingers, don't forget thumbs
Under the nails, there there be bugs

Carry on scrubbing, at least 20 seconds
Sing happy birthday, twice for good measure

Now for the rinse, with clean, running water
And once you have dried, you're a true virus fighter.
