5 If one dunks in boiling water a vessel which requires whitening by fire, the vessel may not be used with hot food even if it is not next to the fire. Rema: But it is permitted to use for cold food, even from the outset [without dunking in boiling water either], through washing and scrubbing well, and all the more so with regards to a vessel which requires dunking in boiling water. And this can only be done in temporary circumstances such as when he is in the house of an idol-worshipper or it is after the fact. But if he wants to use these vessels on a regular basis, there are some who are stringent and say that even to use it with cold, dunking in boiling water or whitening through heat is required. It is decreed lest once come to use it with hot, and this is our custom. And even vessels which were used for cold, if there is a concern that they were used to heat wine such as a vessel made of silver, our practice is to dunk in boiling water and it should not be changed. And even chests and tables which were acquired from idol-worshippers, it is our custom to dunk them in boiling water, for they may have spilled something hot on them, and this is specifically from the outset, but after the fact there is no need to worry about all of this. And an earthenware vessel which was used for cold, which is impossible to dunk in boiling water, we consider 'after the fact' and we say that it is enough to empty it and scrub it well, and it is permitted to place in it afterwards even sharp foods like vinegar and others like that. And all the more so hard things like spices and others like that, and see above 91.
