It is easy to believe that things should be thrown away when they become rusty. Cast iron skillets don’t have to go to waste. Here are some simple ways I can help you restore your cast-iron skillet, griddle or pan, as well as other cookware.
Why bother restoring rusty cast iron?
Cast iron pans can last for generations if properly. They won’t be damaged by rust even if there is a little.
Don’t let it go, whether your pan is antique or sentimental.
However, cast iron may be too old .
- The bottom of the pan is warped, making it inaccessible for electric or induction stoves. This can be seen by placing the pan on a flat surface to see if it wobbles. However, it should still be usable on a gas-heated stove.
- Cracks in the pan. Although small cracks will not stop you from cooking with it however, be aware that they can cause more damage. Don’t worry if it splits.
- Fire Damage. It is considered fire damage if it turns red (redder that rust). This is a serious problem that is difficult to repair. The red area could be removed by sanding, but the pan might be irreparable.
- Pittingof the Surface. It’s not a problem to pit a small amount. It’s not a problem if you have a lot of food in the pan. You can try sanding the pan, but eventually there will be no more pan.
This article is about a simple fix that you can do at home to a rusty iron pot. The same advice applies to carbon steel, which is a common material for woks.
Removing Rust
The simple way
It may be possible to remove rust from a pan that is new and lightly rusted. Use an old rag or a paper towel to apply oil. Sunflower oil is sufficient. You can wipe the rusty area and check if it is gone. It will come off if it does.
The difficult way
It is not easy to scrub iron cookware. Use soap and detergent. Use soap and detergent to scrub hard. Use abrasives like steel wool. It’s almost exactly the opposite of how you’d clean a cast iron pan.
You should normally protect the seasoning of the pan. To get to the rust, you’ll need to get rid off the seasoning.
This will require a lot more elbow grease, strong detergents and hard abrasives. You will likely also take some of this metal. It doesn’t really matter.
If you have the right equipment, you can even sand down the pan.
This is not working or is too difficult, you can read on to learn more.
The Vinegar Acid Bath
Do not let the title fool you, I’m not suggesting anything hazardous.
Let me first explain how acids and metals react. Cast iron is not a good choice for cooking acidic tomatoes.
Acid baths will react with rust to remove or at most loosen it. It can also react with other metals. It can cause pitting if it is left too long.
Vinegar can be considered an acid. Acids react better when they are diluted, so I recommend a half-price vinegar and half-price water solution. It all depends on the vinegar, which is mainly water. It may take some experimentation to find the right amount.
Cast iron should be left in the vinegar acid bath for at least an hour. It shouldn’t be left in the vinegar acid bath for more than an hour. It can be suspended or turned around halfway through to expose the vinegar.
After it is removed, scrub it again to see if any rust has been removed. Repeat the process until you are satisfied with the results.
Alternatives to the Vinegar Acid Bath
Other Safe Acids
Many soft drinks include safe acids. Coca Cola is acidic, for example. Soft drinks are already dilute so you don’t have to add water.
Lemon juice is acidic but it sounds expensive considering how much you would need. Perhaps lemonade?
These are all experiments. I suggest sticking with cheap vinegar. But, you can still try them.
Oven Self Cleaning Cycle
You may be able use your oven’s self-cleaning cycle if it has one. Place the cast iron in the oven, and allow it to cook.
This treatment can cause irreversible heat damage to your pan .
Electrolysis
Electrolysis can be used to remove rust. There are a few recommendations. It can reverse the rust and turn it back into iron. This is something I recommend avoiding. Electrolysis is a process that uses water to create hydrogen (explosive, flammable and flammable) as well as oxygen (helps things explode or burn). This is a terrible combination. This is not a great combination!
This video explains the process, even though it may not interest everyone. You can also see other ways to clean cast iron. This video is a great background video.
After Taking Out The Rust
After you have repaired the pan, the pan will start rusting immediately. This is especially true if the pan has been stripped of its protective seasoning.
This can be avoided by immediately seasoning the pan.
You can also cover the oil with oil if you don’t have the time. You can use any room temperature, food-grade oil. Sunflower oil is my choice. While you should season the bike as soon as you can, the oil will provide some protection. Think about how oil protects a bike chain.
Be careful with what you cook in this pot! Cast iron cookware can be more easily damaged by acidic foods.
In Summary
It is possible to remove rust with ease (using an oily paper towel or a sponge) or difficulty (repeated scrubbing, vinegar baths).
Cast iron cookware isn’t the most convenient. My Teflon pan is my favorite, as it has no fuss. Nonstick pans are easy to damage so I just throw them away. Cast iron is durable, but it does sometimes need some TLC.
