hi there khathleen and anyone else who doesn't understand why to never use soap on cast iron…
cast iron is porous. that should be 'nuf said.
use hot water boiling water, cold water, old and saltt. that's ALL.
Just curious but what is wrong with cleaning cast iron with soap? I have one cast iron skillet that I've had a long time and I've always washed it off with soap and as far as I can tell it is just fine.
