I don't clean my cast iron teapot
I don’t clean my cast iron teapot. I don’t use soap or a sponge or put it in a dishwasher. Some time ago, I was told that the natural mineral layer that builds up is better for you. The older the teapot, the better. How much truth is there to this? Anyone know? Thanks.
Same thing applies to a cast iron pan or other cookware. You don’t want to lose that surface, and even more importantly you don’t want to remove enamel or cause it to rust, so the dishwasher is definitely off limits. The only “health effects” there really are per say is that some iron gets leeched out but that’s not going to happen with enamel. Enamel is going to prevent that from happening.
