A Verse

A little while ago on Twitter Victoria Coren-Mitchell was wondering about songs to sing whilst washing one's hands for 20 seconds or more. I came up with (to the tune of Guantanamera):-

Handsanitizer, I need a handsanitizer
Handsanitizer, I need a handsanitizer
You spray the handsanitizer
Upon your fingers and palm
You spray the handsanitizer
Upon your fingers and palm
And the thumbs and the back
And then rub it around
Handsanitizer, I need a handsanitizer
Handsanitizer, I need a handsanitizer
