Vodka will stain outsides! Avoid. (Good for sterilizing the insides of used shoes though.)
I recommend Varsol if you have any. Put on old cloth. Work entire shoe. Let dry 1 hr.
Lotion (or Lexol), let dry again, polish & buff.
The gent who recommended the stain remover is probably even better advice,
though I haven't personally used that product, I trust he's right about it.
