This pan was difficult to get completely stripped, but I prevailed in the end. I used Easy-Off, and it took multiple tries to get the stubborn stuff off. This is while applying the first coat of shortening to the bare iron. I tested both pans for lead, even though I've been using them both for a number of years. Thankfully, they tested negative.

The pan on the left has 4 coats of seasoning. The pan on the right has one. I wanted to season them together, but the pan on the right took a long time to strip so it fell behind.

Both pans are in the oven as I write this, getting their 6th and 3rd coats, respectively. I don't have a goal in mind, but I'll stop when the bigger pan looks good.
