Hogsy, I can't answer definitively. I'm really no expert, just read a few things I still have my own questions for. Your CI is like mine: mostly "looks just fine" but doesn't satisfy.
The lingering question for me is about what I said earlier, taking all the old seasoning off instead of putting new over old. There's probably a reason why new seasoning doesn't adhere to "old" and that's why it's considered "best" to remove it all and start over.
My issue is that none of the 3 standard ways of removing seasoning appeals to me, so I have to get over that.
1) I have an oven with a self-cleaning mode I've never used. I don't *think* my CI would get damaged (I'm assuming, perhaps incorrectly, those stories of heat damage are mostly from throwing CI on blazing campfires or BBQs ...?) and then there's the ensuing stink in the kitchen or danger of catching fire in a locked oven? Don't want to buy a new oven that burned up at 900 degrees, warping my countertop too ... if that's a legit risk.
2) I'm adverse to burning skin but might don the proper gloves and mask go with lye/Easy Off even though it likely means more cleanup. I like the freedom to do that outside, away from anything.
3) I have one of those larger battery chargers but don't think I want to invest the time and effort constructing a bath station for this, especially if it's not something that cleans without days of effort? Some more folks here who do the electrolysis method might have more to say.
