i did a ton of research on this i decided on seasoning with crisco instead of flaxseed. it works great
supposedly seasoning with flaxseed it will flake off.
I've heard the same thing and also use crisco. All of my cast iron is full on teflon (or close enough) non stick, so why bother with anything more complicated or expensive?
To strip a pan I stick it on my gasser for about 2hr on high, gets to 650F plus, and all but the toughest burnt on bits turn to ash. For the rest, if I'm restoring an old abused pan, it may take several soaks of easy off. The last pan I did had a few stubborn spots I burned off with a propane torch.
Then clean, clean, clean... green scotchbrite pads, warm soapy water- dry thoroughly, warm on the stove top, and wipe on a THIN layer of crisco. Then wipe as much off as I can with a dry paper towel- put in a 400F oven for an hour. You can repeat if you want, but that does the trick. For the magic non-stick performance, deep fry something. Make a batch of fries, hot wings, whatever. Then when you clean the pan it'll be super awesome non stick- at least until you cook something acidic, but that's what the ss pans are for.
I think too many people try to over think things. And I wash my pans regularly with dish DETERGENT and suffer no ill effects. It is my belief that the "don't wash your cast iron" old wive's tale came from back in the days when cast iron was the standard cookware, and people still washed with SOAP (soap != detergent). One of the main ingredients and soap is lye, and lye eats off the seasoning. Modern detergents are all synthesized in the lab and have no damaging effects on your cast iron (don't quote me, my unproven opinions from my limited experience).
