I’m opposed To using chemicals on a pan.
As far as the oven method, it’s ok to do on my oven. If
Your oven doesn’t allow for it, you can accomplish the same in a super hot gas or charcoal grill.
I feel the same about chemicals in my cookware, but I'm okay with power tools. I think the power tools method is what the OP is planning to do. Am I the only one who got that impression?
