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!)
