Stripping Down To Restore: Reviving A Cast Iron Pan's Glory

If your cast iron pan is looking a little worse for wear, it may be time to strip and re-season it. Cast iron pans can become flaky for a number of reasons, including the build-up of oil residue, which can burn and flake off. To fix this, you'll need to strip the pan of its seasoning, either by using a fire pit, wood-burning stove, or self-cleaning oven, before re-seasoning.

How to strip flaky seasoning from a cast iron pan

Use a fire pit or wood-burning stove to strip cast iron

If you have a rusty, neglected cast-iron pan, you can strip it down using a fire pit or wood-burning stove. This method is simple and won't stink up your house.

First, build a campfire in an outside fire pit or use a wood-burning stove. Get some nice coals going and wait until they burn down to hot ash. Next, bury your cast iron pan, face down, in the ash and leave it overnight.

The following day, the pan will be covered in ash. Remove it from the ash and bring it inside to wash with hot, soapy water. You can use steel wool to remove any remaining seasoning, rust, or flakes.

This method is a great first step in restoring a rusty, neglected cast-iron pan. It will strip away most of the seasoning, leaving you with a clean slate to work with. After stripping the pan, you can then re-season it to your liking.

Using a fire pit or wood-burning stove is a convenient and effective way to strip a cast-iron pan without creating a mess or unpleasant odours in your home.

Use a self-cleaning oven to strip cast iron

If you don't have access to a fire pit or wood-burning stove, you can use a self-cleaning oven to strip cast iron. This method will stink up your house, so it's best to do it on a day when you can open all the windows.

To strip your cast iron pans in the oven, set them upside down on the middle rack and close the door. Then, run the self-cleaning setting. Allow your pans to cool in the oven, then remove them and wash with hot soapy water. If needed, use some steel wool to remove any remaining seasoning, rust, or flakes.

Before you start, make sure to inspect your pans for any cracks or breaks. You don't want to waste your time restoring a pan that's damaged. Knock off any excess buildup outside using a stiff wire brush. Then, prepare your oven for cleaning according to the oven manual directions. Some manuals will recommend removing the oven racks, but you can leave one in for the cast iron to sit on.

Place the wire rack on the next-to-bottom guide rail and then place your cast iron pieces on the rack, upside down. Make sure the pieces are not touching each other or the sides of the oven. Depending on the size of your oven, you can usually fit around four pieces.

Close the oven door, lock it, and set the timer. Most ovens can be set for 2.5 to 5 hours, but 3.5 to 4.5 hours seems to work best for stripping the pans. During the self-cleaning cycle, the oven will use very high heat to burn away built-up gunk and mess. It is this heat that will burn away the gunk on your pans.

The cycle can produce strong odors, so it's a good idea to turn on a ventilator fan or place a window fan in the kitchen to suck the air out. When the cycle is finished, allow the oven and cast iron to cool before handling them. You will also need to use hot pads to protect your hands. You will find a pile of black ash in the bottom of your oven, which you can easily wipe up.

At this point, your cast iron should be bare metal. If you leave it like this, it will rust quickly. You must "cure" or "season" it. While the pan is still warm, use a folded paper towel or clean cotton cloth to apply a thin, even layer of shortening (such as Crisco or a generic brand) to the entire surface of the pan, inside and out. Make sure you don't miss any spots, or they will rust. Ideally, the pan will still be warm enough for the shortening to melt into the metal.

If the shortening doesn't melt, turn the oven back on to about 300°F and bake the pan just long enough for the shortening to melt. Be careful to put a drip pan of some sort beneath the pan to catch any drips and avoid making a mess in your freshly cleaned oven.

After applying three coats of shortening in this manner, put on one very thick coat and place the pan in the oven at 300°F for about 20 minutes. This may produce smoke, so it's a good idea to turn on the ventilating fan and put a fan in the window to suck the air out. After 20 minutes, shut the oven off, open the door, and let the pan cool until it's safe to handle. Then, take it out and wipe it down. Your cast iron is now ready to use and is as good as new!

Remove loose flakes with light scouring

If your cast iron pan is flaking, it means the seasoning wasn't done right in the first place. The flakes are burnt oil that has built up in the pores of the pan and when it gets too hot, it flakes off. To fix this, you'll need to remove the loose flakes with light scouring.

Firstly, check if the flakes are coming off by trying to scrape them with your fingernail. If they are coming off, use a metal scouring pad, steel wool, or even a putty knife to lightly scour the pan and chip away the loose flakes. If the flakes don't come off easily, leave them alone and season the pan as normal.

If you are unhappy with the flaking and want to start over, you can strip the pan and reseason it. However, this is not recommended as old cast iron seasoning is the best and starting over is usually more trouble than it's worth. If you do decide to strip the pan, you can do so by using a fire pit, wood-burning stove, or self-cleaning oven to burn off the seasoning. Bury the pan in hot ash from a campfire and leave it overnight, or place it upside down in a self-cleaning oven and run the cleaning cycle. Be warned, this will stink up your house! After stripping the pan, be sure to immediately season it again or it will start to rust.

Re-season the pan by rubbing with oil and baking

To re-season your cast iron pan, start by removing any remaining flakes or residue. You can do this by lightly scouring the pan with a metal scouring pad, steel wool, or sandpaper. If there is a lot of residue, you can also use a pan scraper to remove it. Once you have removed the residue, rinse the pan with warm, soapy water and dry it thoroughly.

Next, you will need to apply a thin, even layer of cooking oil to the pan, inside and out. You can use extra virgin coconut oil, flaxseed oil, canola oil, or vegetable oil. Be sure to wipe off any excess oil with a paper towel, as using too much oil can make your pan sticky.

After oiling the pan, place it upside down on the top rack of your oven. Place a sheet of aluminum foil on the bottom rack to catch any excess oil that may drip. Then, bake the pan at 450-500 degrees Fahrenheit for one hour. Allow the pan to cool, and repeat the oiling and baking process as needed. Two to four repetitions are recommended for the best results.

As you continue to use and care for your cast iron pan, you will notice that the seasoning improves and the flaking becomes minimal. With proper maintenance, your cast iron pan will last for generations.

Use coarse salt or sandpaper to remove loose flakes

If your cast iron pan is flaky, it's likely that it needs to be stripped and re-seasoned. This is a simple process, but it is time-consuming.

Firstly, you'll want to remove any loose flakes. You can do this by lightly scouring the pan with coarse salt or sandpaper. If using salt, pour 2-3 tablespoons into the pan and scrub with a clean kitchen rag or paper towel. If using sandpaper, be sure to use a low grit (40-80) to avoid scratching the pan.

Once you've removed the loose flakes, it's time to re-season the pan. This involves rubbing the pan with a thin layer of oil and baking it in the oven at 450-500 degrees Fahrenheit for one hour. Place the pan upside down on the top rack of the oven and line the bottom rack with aluminium foil to catch any excess oil. Allow the pan to cool, then repeat the process as necessary until you achieve the classic black patina.
