Always an Entree

There's a stain upon my plate,
Unobserved when viewed.
Discovery would heave weight,
Unfortunately i'm never nude.

Disinfected then rinsed,
Dried and set.
Concealed with pleasing elegance,
And garnished with regret.

Devoured by those I know,
Smeared in grease.
Back alone I go,
To cleanse for tomorrow's feast.

Your not allowed at my sink,
I can't trust you to see me bare.
My purest form, in such a blink,
Could reveal my impure wear.
