Here you go. I just googled it.

Do you remember Grandma's Lye Soap,
Good for everything in the home,
And the secret was in the scrubbing,
It wouldn't suds, and wouldn't foam,

Oh, let us sing right out (sing out!)
For Grandma's Lye Soap,
Sing it out, all over the place!
For pots and pans, and dirty dishes,
And for your hands,
And for your face!

Little Therman, and Brother Herman,
Had an aversion to washing their ears...
Grandma scrubbed them with her lye soap,
And they haven't heard a word in years!

Oh, let us sing right out (sing out!)
For Grandma's Lye Soap,
Sing it out, all over the place!
For pots and pans, and dirty dishes,
And for your hands,
And for your face!

Mrs. O'Malley, out in the valley,
Suffered from ulcers, I understand,
She swallowed a cake of Grandma's Lye Soap,
Has the cleanest ulcers in the land!

Oh, let us sing right out (sing out!)
For Grandma's Lye Soap,
Sing it out, all over the place!
For pots and pans, and dirty dishes,
And for your hands,
And for your face!
