I'm sorry Carolyn, I left out a step!   After the first oiling, I rinse it under hot water.  That first oil is more of an "oiled scrub"...THEN I dry it with the paper towels and heat it in the oven.  
I use Pam for all of the steps....since Greg Stahl posted the low temp Pam method after the convention... :)

Charlee: Where is it posted about the low temp Pam method for seasoning?

Thanks

Oh, and one more thing, Perry uses an old T-Shirt, Fruit Of The Loom, very important to get that correct!   ::)
I wonder if old Hanes T-shirts will work as well...?

Well, now that I've been enlightened with so many good tips, I've got my work cut out for me, and since today's foot x-ray showed no fracture, I won't have that excuse either once the swelling goes down.  That said, I would first like to purchase a Dremel and some s.s. wire wheel attachments...

Thanks again for all the info!

Carolyn, in  a pinch, Hanes will work, UNTIL, you can get some Fruit of The Looms.  ;) ;D

Perry,  I'm just glad that you specified TEE SHIRT by Fruit of the Loom, cuz they do make other apparel...

Perry,

  IF you are using Fruit of the Loom articles other than Tee shirts, that is OK. Rags are rags and if you wash them it shouldn't make any difference. That being said; You should continue to specify that you use only Tee shirts in your posts to prevent perverts from purchasing your old iron for all the wrong reasons...........

Bill, I'm not Charlee but here is the link: http://www.griswoldandwagner.com/cgi-bin/yabb/YaBB.pl?num=1223902841

Ron: Thank you very much. At the convention I seen this members cast iron items seasoned this way and they were very impressive. I am going to try this method.

All right, all right...

I'm not taking any chances.  I'm sticking with my rags made from old, torn pillowcases!

Hi Carolyn,

I wonder why you're having so much trouble with the flash rust?  Maybe you are in a very humid place.  Rust doesn't form on bare iron below 65% humidity (but it's near 100% at the surface of the iron when you're drying it.)  Maybe your best bet is the oil wipe method many have described above to physically rub the flash rust off.  I've done that a few times too and I find paper towels are better than cloth for this because they are 'scratchier'.

I just tried Greg Stahl's new PAM method on several pieces and it worked really well.  I use the Lye followed by vinegar method with cold water rinse (I most often use a worn green scotchbrite pad to clean off the last bits of residue) and cloth dry.  I notice that the surface has a 'dusty' look and typically shine it up with a drill and wirebrush, but this time I tried just washing them in soapy water and SOS, rinsing well in cold water and cloth drying again.  Into the 250 oven to heat up, spray with PAM and wipe of excess, then 250 for an hour, followed by a hot at 350 for another hour.  This is so much easier than using Crisco, has less odor, and the seasoning looks really good.  The true test was in the cooking and once again I was amazed.  These pans performed just as well as any I have ever seasoned.

Don't get discouraged - once you find something that works, and I'm sure you will, you'll be good to go.  In the meantime, you can't ruin your CI trying different things.

I live in the high desert Jim, pretty dry here, and I get a lot of flash rust too...but you know, it seems that I mostly get it on the old iron.  The newer Lodge and Wagner that I've stripped down and seasoned don't seem to rust like the old stuff does...

Suppose that's because the old iron is a more pure iron, fewer impurities? :-/

In a flash rust thread we had several months ago, I speculated that flash rust isn't a problem - and may help the seasoning process.

Here is the link to that thread.

Charlee, I have come to feel that the older iron I have cleaned does NOT flash rust as quick as the new iron.  I thought that the raw materials used in the older iron was "purer" than the later castings :-/
Wonder if ones water supply has anything to do with it :-/

Couple of thoughts...

Chris, are you saying that you wipe your pieces down with vinegar and do not rinse it off? Everything that I've read about using vinegar indicates that you only want too use it for short periods of time, that if left in vinegar toolong it can actually start to eat away at the iron. Not "arguing" your process... just throwing out what I've read. ( and NO, I don't believe EVERYTHING that I read  :P )

Carolyn, by any chance is your oven gas? I asked because, with my gas oven I noticed quite a bit of condensation will collect while preheating. I always leave the oven door open a bit to allow this to burn off and escape quickly.

Perhaps you could try leave the piece out for a while, after you've cleaned and dried it. Say an hour... and THEN put it in a the oven. Just a thought... no extra work involved in trying, just a little more time  :)

Michelle,

    
    You make a good point. Vinegar IS an acid, and given time,I'm sure it would do some harm. I would not treat it with vinegar without seasoning it within the hour. The first coat of oil should dilute any remaining traces. Perhaps it acts as surface treatment (as discussed in the thread posted above by Jeff) I know the iron turns very dark even before the oil is applied. It makes a very black finish when seasoned.
    I'm certainly not recommending, advocating or even suggesting that this is a better, or even acceptable method, only that this is how I do it. I made a point in my post when I first explained it, that Carolyn (or anyone else for that matter) should stick to the advice of other, more experienced people.
   If someone else wanted to try it out of curiosity on a "less than valuable" piece, I would be interested in any comments on their findings.

This is turning out to be a really helpful thread.  The variety and range of techniques here is amazing!  No doubt some combination will eventually hit the mark.  I have no idea why I have run into this problem as much as I have, although I have noticed it more with some pieces than with others.  And Michelle, my oven is electric, so no excuses there, but your idea of air-drying for a while sounds good -- unless the flash rust really IS due to the humidity here.
Thank you again for all of your great ideas.  I'll let you know what magic combination finally works for me.

Chris,
   I happen to be seasoning some iron today. Always did it on the Gas Grill but to cold here today. So my first attempt in the oven. I will try the vinegar wipe then crisco to see any differance. going to try the pam method also sometime today. There just a bunch of Wagners I been buying. Wouldn't experiment on a Griswold.... ;D

Jesse,

  I look forward to hearing about your findings. I'm counting on you to be brutally honest here. If you perceive some problem, I may have to re-think my method. I have two pieces coming in the mail, and I am going to try the Pam method for myself as well when they arrive.

The acid in vinegar is acetic acid and it is a volatile organic compound - meaning it will evaporate like water.  Its boiling point is around 244 F, so it should dry off in an oven.  Also it needs water to be active, so if that's gone, so is most of the activity.

I'm interested to see the results of the experiment.  That's also a very good point about the water. I haven't looked into it, but maybe very soft or very hard water will cause excessive flash rust.  I know chlorine can accelerate rusting, so maybe heavily chlorinated water could be a problem.
