There's no Sahih hadith that mentions either of the two. The only thing that speaks about cleaning hands are the one's mentioning to lick the finger before wiping them.
Jabir reported Rasolullah said =
"Indeed Shaitan is with you in everything one does. He is there even when you eat food. So if any of you drops a morsel he should remove
any filth on it and eat it and not leave for Shaitan. And when you
finish (your food), you should lick your fingers, for one does not
know in what portion of his food the blessing lies."
[Sahih Muslim - Book of Drinks]
I did a search throughout 9 hadith books and couldn't really find anything that you mention. This was the closest I would say.
