The inside surface of BreezyCooking's pot is not porous since the inside is glazed and would not have trouble cleaning it as you are worried about Anticuchos.
The porous nature of the pot may not make it difficult to clean but it may have a tendency to retain the odour of the last meal cooked in it, particularly if its a strong flavour. What you could do is the same thing I do with my mortar and pestle when a particularly strong ingredient has been crushed in it (especially when it's wet or moist as well, such as garlic). Wash it normally, dry it, then rub the inside of it with salt (in the case mortar and pestle I grind salt in it) thoroughly, then wash out again.
Hopefully the salt, which is a fairly neutral flavour as far as cooking is concerned (you pretty much want every dish will have some salt in it), will get rid of or cover up any strong flavours that were still present.
