NEVER use a sand blaster on cast iron if it is old collectible cast iron you will ruin the value of it. Go to the link dbbls posted and go to the forums. You will learn more about cast iron here than anywhere. Electrolysis for one pan might be a little much look at a viniger bath. The WAGS web site will explain how to do.

Depending on how rusty, wire brush, oil with sea salt mixed in (the salt is a great abrasive and is all I ever clean mine with).

I agree with Toyhaulerz ... elbow grease, salt, oil and a slightly warm oven. Give it time ... it will be just fine.

No no no no, build and good hard wood fire next time you camp. Set the rusty cast iron near the fire. Slowly work it into the fire. Watch it get red hot. Let it cool slowly or let the fire burn out. The item will come out clean of all impurities. This burns out all the old oils also. The item can then be cleaned with water and dryed with a clean cotten cloth. Oil and place next to a heat source to warm the item and allow the oil to soak in. This was taught to me by the people who gave me the old cast iron I use every day (my dear departed ancestors). We do this once a year to remove all old oil and re season. A lot of my cast is in the 50 to 80 year old range and has been through this many, many times.

Sorry to disagree, but why would you want to start over every year and reseason a cast fry pan or whatever? And I think the last thing I would do to an unseasoned cast item is to put water in it. Just my opinion, but just because someone has been doing something the same way for 80 years does not make it right.

I think that after 80 years if it's not broke don't fix it.

The oil gets rancid in the pan; also the buildup of burn oil on the bottom and sides gets funky. We use cast exclusively. Our stuff needs "cleaned" read burned out/off that often and reseasoned. Besides the burn and reseason makes an 80 year old Dutch oven look brand new!

As one who has been using cast iron since 1965, I agree with wayward1.
True I have never used a wood fire to do the cleaning.
But every so often a cast iron item needs reseasoning. You don't always cook with fatty stuff.
But there is no reason for a well seasoned item to go rancid. The secret to that is in the oil. Use plant oil - olive oil, safflower oil, walnut oil. Keep all your cast iron in living quarters with medium humidity. Also, a low oven @ 150 - 200'F for 10 minutes is a good way to make sure cast iron is dry before applying that very thin coat of oil for seasoning.
Re. using water for cleaning, many use electrolysis.
& I, I took the road less travelled by.

Thanks
If it's a good brand, send it to me for refurbishment. I don't cover the cost of shipping, so by the time it's all cleaned up you probably will just want to buy a new one anyway, instead of paying for shipping across the country twice.  (this plan has never worked, but I keep hoping I'll get some free cast iron this way).
