Cookware Tinning

Cookware cast iron is safe to use after passing by a house fire?
vintage mother of my house recently burned … Solid pine car siding was inside walls and ceilings. Everything that was not consumed by fire was covered with a mixture of black soot and oil cook pine lining outside the car. It was a particularly hot fire from his house also had a tin roof held strong and the fire and heat rather than allowing it to burn out and ventilation. The fire was so hot that even the china and earthenware dishes passing burned to a powder. So I worry that the iron Cast saved could be contaminated. It is porous and I worry that could have absorbed the chemicals from the fire that would be best if filtered unpleasant at lunch and at worst can be poisonous. Can anyone advise on this?
Cast iron is porous. Does not absorb contaminants. What what need to do is to make sure surface is clean. This means that heavy cleaning service with a Brillo pad. If you have a dishwasher, run pans several times. After that, recommend rust remover like naval jelly. Finally, rub all over with vegetable oil, let stand overnight, and wash with soap and water. This type of cleaning is a bit sad, old kitchen utensils cast iron is generally well-seasoned, and it takes many years to do that. Methods I have just described are destroyed seasonings. But the spice is the part that could contain contaminants. To season the pan again, never use soap on it and cooking oil and rub on the inside before storage. Some people speed the process by putting the oil pan on a burner to heat – but not hot enough to burn the oil. I never go through this to save a pan, but I understand why someone would do if all they could salvage.
