They've got to be clean, they've gotta be clean, ahhhahh
We wash our hands whenever we eat
And in the bath we wash our ears, our elbows and feet

We gotta be clean
We gotta be clean
It's healthy and keen

We gotta be clean
Ahhh Ahhh
(Yes sir!)

We start each day by brushing our teeth
(Brush brush!)
And getting the plaque and stuff off the smile underneath

We gotta be clean
We floss in between
Like the string must be green

We gotta be clean
Each day's a fight with the forces of dirt
(Dirt! Dirt! Dirt!)

Battling the smudge and the smear and the squirt

(Squirt! Squirt! Squirt!)

What do we do when our shirt is all covered with mustard?
(Mustard! Mustard! Mustard!)
You may just wear it and wear it and wear it for weeks

(No!)
Not Guster...
We wash it, then we wear it

We may be sad
We may be beat
We may be cross or tired or mad but we'll always be neat

We gotta be clean
Like all dishes we've seen
Or a fresh nectarine

Or some laundry that's been through the washing machine
We gotta be clean
(We got to be ahhhhh!)
