Heat pan up for one minute on the stove top...on low...then remove from heat

Then put a 1/2 teaspoon of crisco in the pan....then spread it around with a paper towel.

Then take a clean paper towel and wipe all the crisco out.

Then take another paper towel and wipe it out again

Then take another clean and wipe it out again.

Then take another clean paper towel and wipe it like it's the hood of your 67 GTO

You picking up...what iam putting down ??????

You want that pan free and clear of nothing but 1mil of a coating of crisco.

Then stick the pan in the oven..upside down...then put a cookie sheet on the rack

Directly under the pan ...should be a 2 inch gap ...between pan and cookie sheet

Then turn your oven on to 450...set timer for one hour.

After pan cooks in the oven for one hour ..turn oven off...BUT DO NOT OPEN OVEN for at least 3 hours.

Then repeat this whole process 3 more times

so to preface this, i bought this on ebay i believe and it came to me with those spots and the entire thing was very sticky, i tried to clean it up i finaly gave it a very soapy bath using some steal wool, this looked like this when it came to me except extremely sticky. i used avacodo oil and put some on and rubbed the (This word is unacceptable on Trapperman) out of it. except after an hour i did take it directly out of the oven and left it on the stove to cool. one of my questions i guess is that crispy looking stuff on the side should i just get like a wire brush and scrape this all down to base metal?

BTW, due to the time involved I prefer to do new to me iron in batches so I can do several pieces at a time. And it's perfectly fine to stack pieces in the oven as long as the cooking surfaces don't touch.

I've got a pretty decent sized pile sitting a waiting on me, lol.

Wow ! I hope I never inherit a bunch of cast iron. Lol

okay i gotta ask how many pieces of cast iron do you have. my wife says i have 2 many. i have 3 skillets and 2 dutch ovens

My air grinder ...and a Norton Fiber Disc...cleans the nasty ..
