I bought this cast iron pan at a yard sale with tons of build up on it.
I put it in the oven with the self clean cycle on.
the oven baked off the build up
When I took it out of the oven, it all flaked off.
this is it all brushed off and washed up.
Inside the pan, looks like new.
I couldn't believe my eyes
Ready to use now.
Run your oven for an hour or two.
