How can I de-fluke a pot?

I had a gyrodactylus fluke attack in one tank, and now I need to use the
aquarium decorations in another aquarium. The question is, how best to
ensure that a clay pot used as a spawning area for cichlids will not carry
any flukes with it.

I was gonna boil it for about twenty minutes. Will that be enough?

Best,

it, sorry about that)
