Question for sellers-Do you clean item before ship

May sound like a dumb question, but having bought some recent items, they all came very dirty. Nothing is worse for my confidence if something works/if I got ripped off, as unpacking an item to see dirty, handprints, scuffs, etc.

As I rule of thumb, I also clean off an item with a rag, a light solvent when I put up an ad and photo taking, then when it sells, I re-clean before I pack.

Am I in the minority here?
