How to remove rust from cast iron? Tips and Tricks

Cast iron is a popular choice for cookware because it heats evenly and retains heat well. Cast iron is known for its durability and ability to withstand high temperatures, but over time it can become rusty. If this happens, don’t worry – there are several ways you can remove the rust and restore your cast iron to its former glory. In this blog post, we’ll outline many methods for removing rust from cast iron, as well as provide some tips on how to prevent rust from forming in the first place. Armed with this information, you can keep your cast iron cookware looking its best. So let’s get started!

Types of rust

You can’t stop rust, but you can slow it down. Rusting is an electrochemical process that affects iron-based materials exposed to the elements. It’s basically a corrosive reaction between water, air and salt. So if your metal object contains any iron, regardless of whether it’s actually rusted or not, it can still be affected by this chemical reaction which will make it appear rusty even though there are no actual signs of rust.

The first thing everyone thinks about when they see rusty metal is red dust just sitting on top of the surface waiting to crumble off at any moment. This type of rust isn’t very prevalent because although the oxidizing agent reacts with the iron atoms in order to form iron oxide (rust), it doesn’t actually go deep into the metal. This form of rust is what you see in most cases when it comes to outdoor furniture or gates that have been left unprotected for a while.

It’s not uncommon in areas where a lot of rain falls in short periods to notice a thin layer of white dust on top of the ground, especially after a period of dry weather has followed after heavy rainfall. Although this appears to be part of dirt, it’s actually salt mixed with water from the previous storms. The high concentration of dissolved salts combined with moisture makes an excellent environment for rusty metals to show off their reddish color.

White rust , also known as red rust or Martian rusted iron is a type of corrosion that affects iron and its alloys such as steel, stainless steel and cast iron. It’s called Martian because it looks like this type of corrosion has been formed due to the presence of other minerals that have mixed with the rust itself creating a tint similar to what we see on Mars: red and white.

There are several materials that can be added to enhance this effect and make it more realistic. These include paint or pigment; glass; plastic; plaster; concrete; gravel etc…

Blue rust is actually bare metal exposed to hydrogen sulfide (rotten eggs gas) remaining in air after anaerobic bacteria finishes digesting any organic matter nearby such as decaying leaves, dirt, plants or even animals. When hydrogen sulfide gets into contact with bare metal, it forms iron sulfide on a molecular level. This is a powdery substance that looks like rust but technically isn’t since it’s not formed as a result of chemical or electrochemical reactions with the air.

Iron sulfide contains mostly FeS molecules and some free S atoms which makes up its red coloration. It can also contain some ferrous ions (Fe2+) and water molecules creating FeS(OH)2 which will give the powder more of an orange-ish tone than red making it look even less realistic than plain blue rust.

Blue rust is easily removed during treatment by simply wiping off the surface with your hands or scrubbing whenever you feel like there’s something stuck to it. I don’t recommend using any corrosive chemicals because they might remove more metal than blue rust.

Black rust is actually the same chemical reaction that happens when you combine iron with oxygen, water and carbon dioxide in order to form rust but on a molecular level. The difference is that this process occurs at very high temperatures close to 2,000 °F which can be found naturally in some areas where lightning strikes are common or artificially by creating an environment that will allow it to occur through electric arcs or sparks of electricity. Over time, these reactions create new compounds between the iron molecules, the oxygen molecules and any other materials available making new compounds such as magnetite (Fe3O4), wustite (FeO) etc… These compounds are black so their appearance resembles that of black rust.

Although this form of corrosion is much more realistic than the other types mentioned, it doesn’t create any coloration that resembles Martian rusted iron nor does it make a sound like rusty metal.

How to remove light rust

How to remove rust from cast iron? Cast iron is very durable however it does rust. A good cleaning and removing of old dust and oil will help you get your cast iron back to beautiful condition. Here are 6 ways on how to remove light rust from cast iron.

  1. Remove all loose rust with either a wire brush, sandpaper or steel wool (with these methods make sure the surface is 100% clean). If there is heavy rust use method 2 below instead. Don’t forget to dry your pan immediately after washing!
  2. Fill ‘er up – Use DISTILLED white vinegar in a 1:4 ratio (one part vinegar 4 parts water). You can also add salt but that’s optional. Boil the vinegar solution then let the pot/pan sit in it for a half hour or so. You may need to repeat the process to get rid of all the rust.
  3. Remove small bits of rust with lemon juice & salt, 1 tablespoon of salt per cup of lemon juice to be exact. Heat your pan over low heat then pour some lemon juice on it and sprinkle salt onto your pan while still hot (you don’t have to do this step if you used method 2). Once the cast iron has cooled down, grind away rust spots with coarse salt! If you want you can also rub whole cloves into the rusted spots before grinding them away.
  4. Use tomato sauce! Yes, I said tomato sauce. When baking bread using fresh-ground flour mark bakers often use tomato sauce. They apply the sauce to the bread’s surface, let it sit overnight and wash it off in the morning. The acidity of tomato juice will remove rust easily, just like vinegar!
  5. Use ground cinnamon! Cinnamon is another naturally acidic powder that can be helpful in removing rust spots from your cast iron pan. Just sprinkle some cinnamon on your rusty pot or pan then rub it into all of the rusted areas using a damp cloth. Next let it sit for about 15 minutes before washing away with water and dish soap (or you can use method 2).
  6. Create a paste made up of cream of tartar & lemon juice (about 1 tablespoon cream of tartar per cup of lemon juice). Apply the paste to your pot or pan and let it sit overnight, wash off & dry. You can also use method 2 instead of this last step.

That’s how you remove light rust from cast iron. Just remember that repeated usage will prevent future rust spots! Also make sure you’re not overlooking these other important tips on how to clean cast iron. Have fun cooking!

How to remove heavy rust

How to remove rust from cast iron? Rust is a common problem with old cast iron cookware. Not only does it look bad, but it also makes the piece of cookware unsafe to use until the rust has been removed. There are certain chemicals that can be applied to remove rust from metal, but these can be hazardous if not used correctly and they may damage the finish on the piece of cookware as well. If you’re looking for an easier way to remove rust from your cast iron cookware, there are several natural methods you can try!

Getting Started: How To Remove Heavy Rust From Cast Iron

Cast iron pots and pans have been used by chefs for hundreds of years because nothing beats their durability and even heating qualities. But those qualities mean nothing if those pots and pans are rusty. If you find that your once beautiful piece of cookware has transformed into a rusted hunk of junk, don’t worry. With some elbow grease and determination, you can restore your cast iron cookware to its former glory—and enjoy superior cooking results along the way.

Materials Needed:Old toothbrush or scrubbing pad, Cold water, Baking soda, White vinegar, Cooking oil, Salt, Olive oil, Tea tree oil.

Step 1: Remove the Rust

Use an old toothbrush or scrubbing pad and some cold water to scrub away any visible rust on your cast iron cookware. If the rust has set in deeply, you may have to apply more elbow grease. Once visibly rusted areas are removed, give the cookware a quick wash with cold water to remove any loosened rust particles before moving onto step 2.

Step 2: Season the Cookware

To stop future rust from forming, season your cookware by coating it with cooking oil and placing it in a warm oven for about 30 minutes. Then turn off the oven and let the cookware cool down inside until completely cooled. This will create a natural nonstick coating on the cast iron and keep out any moisture.

Step 3: Remove Existing Seasoning

After removing your cookware from the oven, you’ll need to remove the existing seasoning before applying a new one. So put some baking soda into your scrubbing pad or toothbrush, wet it with white vinegar, and use it to scrub away any existing seasoning on your cookware until all surfaces are smooth. If necessary, apply more baking soda for stubborn areas. Once you’ve removed the old seasoning, rinse off the cookware with cold water and dry thoroughly.

Step 4: Re-Season Your Cookware

Put some salt onto a paper towel or clean cloth while still warm from the oven. Use this salt to vigorously scrub your cookware until it is smooth and shiny. If the salt starts to brown, you’re scrubbing too hard or not rinsing it off quickly enough after applying. Repeat this process until you have successfully removed all rust and previous seasoning from your cookware.

Once clean, put some cooking oil onto the cloth or paper towel and gently wipe down each surface of your cast iron cookware—front, back, top, bottom, handle(s), outside rim (where the lid sits on the base) and inside rim (of a dutch oven). When finished, any leftover residue on the outside of the cookware will give it a matte sheen while leaving its insides shiny.

Expert Tip: It’s important to create a nonstick coating on your cast iron cookware to keep out moisture and prevent future rust. Make your own seasoning by mixing 3 tbsp salt, 1/2 tbsp cooking oil or shortening, and 1 tsp lemon juice in a small bowl until you have a crumbly consistency. Apply this mixture to the insides of your cookware with an old cloth and scrub in circular motions until they’re smooth and shiny inside.

Additional Notes: If you’d prefer not to use salt to clean your cast iron cookware, there are other natural alternatives that work just as well. Try using olive oil for polishing cast iron after removing rust and previous seasoning. Or try making a paste from water and baking soda (about 2 tbsp each) before using a scrubbing pad to remove rust and seasoning.

To prevent your cast iron cookware from rusting in the future, coat them with cooking oil as soon as they’ve cooled down from being in the oven. Then store them in a dry place until you’re ready to use them again.

Once clean, your cast iron cookware will have a better flavor for cooking food since it won’t be releasing any metallic tastes into your meals anymore. Plus, you’ll be able to create delicious caramelization on any foods cooked in these bad boys! Try making some blackened chicken or steak by heating a little shortening or oil over medium heat before searing meat just long enough that its outside is blackened but its inside stays raw. Lastly, adding a little water to cast iron cookware will prevent your food from sticking. But if you find that this causes your food to taste metallic, try dry cooking methods instead by heating the oil or shortening in your pan before placing your food inside—just make sure they’re not cold (place them close but not touching the hot surface) if you want to prevent sticking.

How to prevent rust from forming in the future

Rust can be a pain to deal with. It isn’t always easy to remove all the rust from a gun because it tends to form in hard-to-get locations, one of which is between two parts that have been machined. This usually leaves a very thin layer of rust on both sides, and makes it difficult or impossible to clean up without damaging either part. In this case the only remedy is the old soldier’s motto: “Out Of Sight, Out Of Mind.” If you don’t see it, you won’t care about cleaning it. But what if you do want to remove that thin outer coating? You could take a wire wheel or sandpaper to the parts and then oil them thoroughly, but I’ve always felt that there had to be a better way. A few weeks ago I received an e-mail from Mark Bernard, who suggested using oven cleaner to remove the outer layer of rust. This sounded pretty far-fetched to me, but it made sense that if you could dissolve the top layer of rust, then it would wipe off easily with a rag dampened with oil. The next time I saw some thin spots on my blued revolver parts, I decided to give this trick a try. It worked beautifully! But first let’s talk about how not to clean your blued guns; and don’t even consider using oven cleaner for this application!

How to remove rust from cast iron? This is what happened in one part after only two weeks under the watchful eyes of my new puppy. The rust was rubbed off, but the oil coating wasn’t heavy enough to prevent further rusting.

The first step is to remove all the loose rust and dirt from the surface of your gun using a scraper such as a putty knife or an old screwdriver. If you really want, you can use wire brushes and abrasive compounds like J-B Paste wax finish remover, which will also dissolve rust. Once everything is clean and dry, mix up some oven cleaner according to package instructions. Most brands suggest that you wear rubber gloves when handling this material for this reason. I didn’t at first out of habit, but after getting it on my fingers I quickly reconsidered!

After applying the oven cleaner liberally with a rag, I let it set for a minute or so and then came back to wipe off the parts. It really wasn’t necessary to wear gloves because this stuff doesn’t do anything but dissolve rust.

After wiping down all surfaces that had been exposed to the oven cleaner, I applied a coat of gun oil using yet another clean rag. The surface should be completely covered with a thin film of oil – you don’t want any puddles – after which you can assemble the gun or store it for later restoration work. After two or three days you can come back and reapply another coat if you wish. So how well does this process work? Pretty darned good! I’ve used it on my blued revolvers, rifles, shotguns, and even my Mosin-Nagant without any ill effects.

The oven cleaner will discolor nickel plated surfaces, so if you clean a gun with that type of finish it’s best to wipe everything down with lacquer thinner first. Also be aware that the oven cleaner can dissolve some plastic parts, so don’t let it drip on anything like your grips or sights.

This is what the part looked like after using the oven cleaner solution for about 30 seconds. You can see how rusty it was before scrubbing! The metal underneath wasn’t affected by the rust remover, showing just how thin an outer layer of corrosion there was to deal with here. I must admit I’m very impressed with this cleaning method; much more so than I thought that I would be. It’s so simple and fast to use, yet the results are amazing! Whether it will work for you depends on how much rust is present, obviously. In general, blued steel parts should clean up very nicely with this process since they have a thicker layer of corrosion to begin with. The same can’t always be said for nickel plated or stainless steel guns; but then again, oven cleaner also removes paint and wallpaper easily enough if left on long enough! For best results remove all traces of oil and grease before applying oven cleaner because it won’t evaporate like regular gun cleaners and solvents do (which is why you can get away without using gloves). Also don’t let any puddles accumulate on surfaces that you don’t want to rust.

Additional tips and advice for cleaning and maintaining cast iron cookware

  1. Never clean your cast iron with soap and water! If you do, the pores will fill with soap residue and you will never be able to get that off. You can use salt or a stiff brush, but most importantly: just don’t do it!
  2. Don’t let your cast iron soak in water for long periods of time. If you need to wash it out, put some plain water in there and bring it to a simmer, then use a stiff brush to clean it out.
  3. When cooking, try not to let your food stick to the pan. If you are having trouble with this you should watch some youtube videos on how to properly maintain your cast iron cookware!
  4. After cooking, scrub the pan with salt and put it away while it’s still hot. If you wait until the pan has cooled down some, that will let it soak for much longer and food can stick to it much easier.
  5. After cooking, pour some olive oil in your cast iron skillet and wipe it around. This will prevent rust from forming from all the moisture in there!
  6. When storing your cast iron, put a little bit of olive oil in it and wipe that around the pan. This will prevent any rust from forming.
  7. To get old crusted on food out, add about 1 teaspoon of kosher salt to 2 tablespoons of coarse ground black pepper, then scrub with a paper towel or dish cloth until it’s all off!
  8. When cleaning out your cast iron pan, you can add some water and bring it to a low simmer and let the steam get in there and loosen up all the old junk stuck to the bottom of your pan. Then take a paper towel or dish cloth and wipe it all out while everything is still hot!
  9. If rust starts to develop on your cookware, just take some steel wool and scrub it down to the bare metal, then re-season it.
  10. If you want to use your cookware for frying at really high temperatures (like 500F), start out by heating up the pan without anything in there until everything gets super hot and starts smoking. Then add your oil and then your food. This should burn off any pathogens that would be killed by cooking at such a high temperature.
  11. If you want to use your cookware for frying with animal products, start out by heating it up dry until everything starts smoking! Then add some oil or lard or tallow and let that heat up, then add your food! This should burn off any pathogens that would be killed by cooking at such a high temperature.
  12. If your cast iron cookware develops blisters, just sand them down with some fine sandpaper and re-season it. It might not look pretty but it will work just as good! And to help protect the pan, put some oil on the sanded down spot.
  13. If your cast iron cookware develops rust spots that aren’t too bad you can scrub it down with steel wool and re-season it!

How to remove rust from cast iron? To clean up your cast iron after cooking something greasy like bacon, just heat up some water in it and let the steam get in there and loosen up all the old junk. Then take a paper towel or dish cloth and wipe it out while everything is still hot!
