Question about Romertopf clay baker

[FlyingChopstik]

Hey guys! I just bought a used unglazed romertopf clay baker on ebay. I know that you have to soak it before cooking in it but if its used (with the possibility that it hasn't been used in a while) do you have to do anything more to unclog the pores?

I would soak it then put it in a cold oven and heat to a really high temperature for about a half hour or hour.  Turn off the oven and let it cool.  That should burn off grease and kill any nasties.  Never use soap.
