Cast iron cookware originated in China during the Han Dynasty, was adopted by Europeans, and eventually made its way to America. The use of iron for many other purposes predates cookware because the process of casting had yet to be invented. Once that process was developed, it was used for water pipes, cannons, and other objects.

Many cast iron skillets on the market today are Chinese schlock (surprise, surprise). The really good ones, which are what you want, can be quite expensive if they are new. To get a deal though, obtain an older one and restore it to its pristine condition. Have a look at garage sales, estate sales, or Goodwill. The degree to which it needs to be refinished, the less of a financial investment you will likely have to make. Once you find your prize, it’s time to restore it to a useable condition.

Remove the Cast Iron Skillet Rust

Most of the sites on the internet will tell you to remove rust with steel wool and this is fine if you have a very mild case of oxidation. But let me tell you, this will take a long time and will work you to the bone if it is worse than that. Instead, I use a grinding wheel attached to my Ryobi cordless drill to expedite the job. Work smarter, not harder, as Gramps used to opine.

The grinder in the image above came straight from Home Depot and worked out just right for attacking both the bottom and sides of my skillet as well as the inside corners. Keep even but light pressure.

It’s likely that the outside will need some work as well. In my case, I had some flakes that needed to be chipped off before applying the grinder. For this, I used a old flat-blade screwdriver and my trusty 16 oz. hammer, which I bought at the beginning of my carpenter apprenticeship back in 1979. Still going strong. That was when Craftsman was the premier brand for hand tools. That’s a bit of America we’ll never get back. Sigh.

Seasoning Your Cast Iron

Seasoning your cookware is the most important maintenance step; this is what gives it a non-stick cooking surface. After following the steps above and you have a good surface (it does not have to be shiny, just rust-free and smooth) it’s time to season it.

  • For the first seasoning, apply a thin coat of peanut oil on the entire surfaces of your skillet including the handle.
  • Pre-heat your oven to 350℉.
  • Put your skillet in and let it bake for an hour.
  • Turn off the oven an allow it to cool

That’s all there is to it! Do it at least twice before cooking in it. The handle and outside only need to be done the first time. This is done as a rust inhibitor. Ideally, you should season your skillet after each washing, but you can judge when it is due by the level of non-stickiness.

Properties of Cast Iron Cookware

  • It is an easy way to more of the mineral iron into your diet. One cup of foods like applesauce, chili, tomato sauce, stew, and scrambled eggs will gain about six to eight milligrams of iron after being cooked in cast iron cookware. This is important for all of us but especially us avid runners and other workoutaholics.
  • It will last a looooong time. In this age of planned obsolescence, it is nice to have something you can pass on to your offspring.
  • It is very heavy.
  • It conducts, distributes, and holds heat well.
  • Unlike some other materials, it won’t develop a convex bottom over time, casing wobble and uneven cooking.

That’s about all there is to restoring a rusty cast iron skillet. With proper upkeep, it will not just serve you well, but it will outlast you.
