Gentlemen;
At first the thread addressed pots and skimming spoons ~ OK.
When it comes to ladle cleaning it's comparably easy stuff; All a fellow has to do when a flux is needed is to simply do the initial stirring with the ladle. This will clean off all exterior crud. For the unwanted material inside simply tap the rod portion of the handle gently against the heat-shield of your alloy pot (typically the 10-pound version as heated with a propane burner) - this will cause the loosened crud to fall off into the alloy where, in sequence, you'll be using your spoon to remove the impurities anyway.
Good morning,
Forrest
