Is there a possible problem with using pots and pans that having a non stick coating?


New (without a Hechsher):

There is no Halachic problem with new Teflon pots (after Kashering them – see link below)
Some, however, have a Hiddur to avoid using new Teflon pots for Pesach. Some even avoid using it throughout the year too. These are not Halachically mandated.


If they were used for Treif, they should not be Kashered.

Similarly, if they were used throughout the year for Chometz, they should not be Kashered and may not be used for Pesach.
