How to Remove Rust from Cast Iron? Tips and Tricks

How to remove rust from cast iron? Clean & Maintain Your Grill

Whether you have an old car, boat, or just live in an area with high humidity, rust can occur on cast iron surfaces. If left untouched for too long, the rust will eat away at the iron surface and create small holes that are impossible to repair. That’s why it is essential to remove the corrosion as soon as possible before it damages your property any further! Many people have cast iron in their kitchen, whether it is a pan or casserole dish. What can you do to restore your cast iron skillets and pans? Cast iron is a great material for cookware because it heats evenly, retains heat well, and lasts forever. But sometimes things happen that cause your pan to rust.  If the rust has not eaten into the metal too deeply or spread beyond just one spot then there are ways of removing it yourself with some elbow grease and supplies from your local hardware store.

Fortunately, there are several techniques you can use to remove this unwanted substance from metal surfaces without damaging them any more than they already have been. How to remove rust from cast iron? Let’s take a look at these methods below!

Mix a solution of dish soap, lemon juice, and salt in a container

When you are dealing with a stubborn stain, it is best to be prepared. So before giving up on that cast iron skillet or pan that refuses to clean despite your efforts, let use a traditional trick from Mom: mix together dish soap, lemon juice and salt until the liquid starts looking cloudy – this will remove any built-up mess caused by food oils!

In order words, wash as much of these grime directly off using hot water first then apply some bleach mixture if necessary after washing thoroughly again because otherwise those tough spots might never come out even when diluted enough times.

That is really all you need to do. The process is not as complicated as it might seem at first sight – but everything else depends on whether you want to work with such a toxic cleaning chemical or not. People who know how this works say that if you mix 2 tablespoons of dish soap, 1 tablespoons of lemon juice and 1/4 cup of salt in a bowl add the mixture to 1/2 gallon of hot water and stir well. Then put your stained pans into this bleaching solution, fill the container with warm water just enough to cover them, let sit for 10 minutes then remove scrub if needed, rinse thoroughly and dry off.

It is easy to prepare dish soap mixture in advance so you can use it when needed. Moreover this mixture cleans your cookware without inflicting any damage unlike oven cleaner which can ruin seasoned layers and start a corrosion process.

Some others say that it is a good idea because it works while it is also a very cheap and simple solution. The effect of using dish soap, lemon juice, and salt for removing rust from cast iron seems to be pretty good – I would say it does 85-90% of the job effectively (this is not a bad result considering how dead simple this method is). Why does it work: Salt acts as an abrasive agent that removes rust from metal surfaces. As for dish soap and acid from lemon juice they help dissolve rust on metal surfaces even faster.

The method of using dish soap, lemon juice, and salt in a container for removing rust from cast iron is safe to use (provided that it is done properly) and should restore a large part of your rusted cookware but probably will not 100% restore like stainless steel would do. If you want your cookware to be restored completely then consider getting a new piece. If you don’t care about looks then feel free to leave it as it is (rust provides an additional layer of protection for cast iron).

While the advice to use a mix of dish soap, lemon juice, and salt in a container is widespreadly spread on the net, there are some things that are not mentioned at all.  Many people who complain that this way didn’t help them get rid of the stains at all – all you can do is try and see if it will work for you or not. Either way these folks recommend using rubber gloves and working somewhere well-ventilated (preferably outside) because the smell of bleach is strong and not really pleasant.

How to remove rust from cast iron? There is no guarantee that your rusted cast iron piece will be 100% restored and rust free and these chemicals will damage your cast iron cookware if you do it wrong. And here is what they do to your utensils:

First thing first – how to properly clean your cast iron skillet. Let us start by saying that using soapy water with scrubbing bubbles is out of the question – this kind of detergent will ruin the seasoning layer. It must be mentioned though that once you season your pan with oil on high heat (for example with flaxseed oil) it creates a perfect food-grade non-stick surface which is oven safe and will repel water. There is no need to season your pan if you are planning to cook acidic food because those dishes will do that for you. If you want to be sure that there will be no reaction between your dish and seasoning, try using vinegar as a preservative – it will severely impact the flavor of anything cooked in cast iron because it will evaporate during cooking anyway.

Add baking soda, vinegar and water to the container

Baking Soda (sodium bicarbonate) is a mild alkaline with cleaning properties that help loosen grime and dissolve dirt, grease and stains when mixed with a liquid such as water making it one of the perfect ingredients to use in many rust removal recipes including this one. Therefore, that helps remove rust by neutralizing the protective oxide layer formed on the metal surface. Water – I think this one is pretty self-explanatory but just in case, water works great as a solvent to dissolve all ingredients and also help them spread evenly over the rusty surface which speeds up the rust removal process significantly.

More specific, baking soda is something you should keep in your kitchen cupboard. It can be used for many things around the home and around the yard including removing rust, deodorizing food containers and making homemade toothpaste. Baking soda’s absorbent qualities make it a great product to use if you need to remove rust from metal surfaces. When baking soda comes into contact with the rusty surface it will neutralize the minerals that cause corrosion and rust, leaving all of those unwanted particles on top of your material ready to be washed away with water. Once the powder has dried, simply brush away any residue left behind by baking soda and proceed to wash as usual.

One part water to two parts baking soda are combined together in a jar to demonstrate how far this mixture will stretch when necessary. The scientific explanation behind what’s happening here is pretty technical, but essentially what ends up occurring with regards to chemical reactions is that each molecule within these ingredients will separate themselves from each other because they’re unable to hold onto certain elements anymore.

The baking soda and the hydrogen peroxide essentially “turns inside out” to create a reaction capable of dissolving even the unhealthiest buildups within your home. It should be noted that this is extremely bad for septic tanks, so if you do ever use this method it’s important not to dispose of the solution down your drain. Additionally, there are several other chemicals present in your average box of baking soda powder that can become dangerous if inhaled or swallowed, which is why you should always wear protective eyeglasses and gloves whenever working with this material.

How to remove rust from cast iron? How much baking soda to use? Baking soda is used for a wide range of purposes – from cooking to cleaning, and even as an effective medicine, so the dosage varies depending on what you are doing with it. For instance, baking soda will remove rust from plank flooring quite effectively when combined with a little elbow grease! It is safe to use on wood floors, but be sure to follow these steps:

Step1: Make a paste out of baking soda and just enough water to make it spreadable (about 5 parts baking soda to one part water). The paste should have the consistency of sour cream. Apply the paste generously to the area you want clean, overlapping onto adjacent areas.

Step 2:Let the paste sit for about 10 minutes. Then start scrubbing the floor, again overlapping into adjacent areas as you go. Scrub with a damp sponge mop or stiff broom-almost like “painting” the paste onto your wood floor.

Step 3: Wipe away any residue with a clean, damp sponge mop and rinse well with water until all of the baking soda residue is gone.

 Step 4: Repeat steps 1-3 if necessary.

In contrast, this often confuses users as they may think that the baking soda is making their skin worse. In those cases you should continue with the treatment and note any changes so you can try to pin down what caused your flare up.In rare cases, people have reported a burning sensation with the use of baking soda. This may be due to an allergy or sensitivity unique to the individual, but it could also be a sign of irritation from using too much baking soda. Use lower concentrations if this happens, and consider discontinuing usage if the problem persists after trying several weeks with dilute concentrations.

Please keep in mind that everyone’s skin is different – some people find relief from seborrheic dermatitis by only water, while others need more aggressive treatment. In the end you should listen to your skin and do what works best for you!

Using vinegar mixed with water is another method that you can employ to get rid of unwanted rusting on your pans: This ingredient is economical, cheap, and easy to find at just about any supermarket or pantry. Furthermore, it is non-toxic and not caustic making it safer to use around children. The acetic acid in vinegar reacts with the rust on your pan turning it into a soluble salt which can be dissolved by plain water. Vinegar rust remover is formed by diluting white distilled vinegar with water in a ratio of 1:3 or even more if necessary. This solution can be applied to all types of surfaces affected by rust and corroded steel elements.

How to remove rust from cast iron? Vinegar rust remover can be applied in various ways. The simplest way is to soak an absorbent material (e.g., a piece of cloth) in the solution and apply it directly to rusty parts, or alternatively pour the vinegar on them. After 10-15 minutes, depending on the degree of corrosion, the surface will have corroded and can be easily wiped or brushed off, leaving the metal clean. Another way is to pour the vinegar rust remover onto a cloth and gently rub rusty surfaces with it. In case of severely rusted parts, you may have to repeat all procedures several times even though after one application you should already see some results. You can also prepare a more concentrated solution of vinegar rust remover to remove really tough rust.

Keep cast iron in a cool and dry place

When it comes to cookware, cast iron is one of the best performers. Its even heating and resistance to water make pans made from them ideal for almost any cooking task you can think of. And because they are so durable, they will last decades if not centuries. The important characteristic of cast iron utensils, which you must know about, is that the more often you use it, the better it gets. This sounds a little bit counterintuitive but if you understand how it works then it’s obvious. When exposed to high temperature during the cooking process, the metal transforms from hard and brittle to soft and tough. Known as “Seasoning”, this way its surface becomes smooth and non-stick for easier cleaning .

Always try to create a dedicated storage space for your cast iron. That way, you know you have a safe, secure, and dry spot for it to be kept when it’s not being cooked with.

How to remove rust from cast iron? There is a few of our top cast iron storage ideas:

Firstly, Dry cabinets: Cabinets and cupboards are the most obvious choice when considering how to store cast iron. Every kitchen has them, and as long as it’s not directly next to or underneath the sink, it should be dry enough to store cast iron cookware. Since the maximum temperature for most cooking surfaces is usually 450°F, using storage in cabinets or closets should be safe. This type of storage becomes unsafe when you consider the possibility that people will place pans on it without properly thinking about what’s below.

This means never storing cast iron cookware above appliances like ovens, microwaves, dishwashers, coffee makers, etc., which can get much hotter than 450°F during normal use. Doing so may result in damage to your cast iron cookware and/or surrounding surface. Even if you’re not concerned about ruining your cast iron pie pans by heating pie crust too long at Thanksgiving dinner, you shouldn’t risk this because of potential fires that could occur from flammable items in the kitchen.

Concerning storage for heirloom or family pieces, cabinet racks are probably best when considering style and safety. Using a cabinet rack protects the cookware when guests are present. However, this type of storage can also allow certain parts of your collection to be less accessible when needed. Sliding doors are another option if you want to make sure all of your cast iron is out “in the open” and not behind closed doors where it may be forgotten about until needed again.

The problem with these options is that they can be expensive and take up more space than some may prefer (depending on cupboard space limits). If you only have one or two pans to store, drawer inserts might work fine; however, if you have a large collection, it becomes more difficult to find the right storage option. Just remember that your cast iron should be stored in a cool area or cabinet out of direct light. If left on the counter around sunlight, the cookware will absorb heat and lose its season each time this occurs.

Secondly, On the wall: A great custom-made alternative to cupboards and stovetops is to install hooks on the wall, from where you can hang your cast iron pots and pans. The wall hooks need to be sturdy and well embedded, as they have a lot of weight to handle in the long run.

Depending on the size of your cast iron pots and pans, longer hooks might be necessary. It’s important to use nails or screws at least 1.5 inches long so they have a strong grip in the wall and don’t fall off easily. If possible, anchor them into a stud for extra strength.

How to remove rust from cast iron? Felt pads underneath each hook will prevent any damage to your pot or pan as well as protect your wall from scratches and grease stains – these are available at any hardware store for less than a dollar.

Do not soak the cast iron

Cast iron is very prone to rust. It’s best to limit its exposure to water as much as possible. Don’t soak your pan in water in order to clean it.  It might seem like a good idea as you’ve got all that lovely bacon grease buildup on the pan, but if you want to keep your non-stick surface in good condition, pouring water into a hot pan is a big no-no.

If you do this often enough, you’ll strip that essential non-stick layer right off, and end up with flakes of black or grey debris floating about in your soup or scrambling your eggs. That’s because the coating is specifically designed not to bond with fat – otherwise everything would stick horribly to the pan and we’d be back to scrubbing with soapy steel wool again. So when you’re removing stuck-on food, either use a non-abrasive pad or simply wipe the pan clean with a damp cloth and dry it thoroughly.

If you ever see this advice – don’t follow it – soak the pan instead. If there’s grease, or dried-on food, or any kind of grime on the surface of the pan (remember: we’re not talking enamel roasting trays here), fill it with water and leave it for 5 minutes before washing as normal. The fat will have softened and loosened, allowing you to give it a quick scrub and rinse without fear of damaging your precious enamel coating. And pay a little more attention to the base of your pans too – another common mistake is using a metal scourer on the part that actually sits on the hob.

How to remove rust from cast iron? Many people avoid the hassle of cast iron cleaning by just letting their pan sit dirty forever. After all, since cast iron is fairly impervious to most outside forces it doesn’t seem like there would be any problems. The problem comes with not removing stuck on food particles and other junk that can cause rusting, which over time will start to put the metal. Not only is this unappealing, it makes your pan harder to care for in the future. This rule does take a little getting used to when you think about the fact that you actually have to scrub at your pan after each use if it isn’t going in the dishwasher. In many cases these pans are seasoned enough to make this job much easier than traditional non-stick pans. Cast iron will develop a non-stick patina over time that makes the cleaning easier, but it does still require some care.

Scrape your pan after cooking: After cooking many people like to loosen all of their food bits that are stuck on with water and then let them simply slide right into the sink when they dump out that water. This is another issue where cast resistance can lull you into complacency because cast iron is so much harder than other pots and pans, so you think it’s okay to do this. This actually rids your pan of one of its key defenses against rust, which is the seasoning on  the inside of the cookware. The seasoning layer is simply oil that has been baked into the pan at high temperatures. This happens when you first receive your new cast iron cookware or if you’ve had it for a long time and haven’t made any recent changes to your cooking technique, but after frequent use scraping off the food bits with water it’s no longer there to protect against moisture coming in contact with the metal itself. This is what causes that dreaded rusting effect on cast iron pans.

Never put your cast iron in or near water: This may sound like an odd rule since most people aren’t adding their frying pans to boiling water, but if you let it soak or wash your cast iron pan in the sink you run a big risk of rusting. This is why we recommend using a stainless steel pad to get stuck food bits off while you’re cooking and opting for our next rule.

Let dry completely before using again and do not store food in your cast iron

Rinse off all of the residue of your cast iron skillet with water immediately after cooking. You may then towel dry the skillet or set it on the stove over low heat to evaporate any remaining water. If you have allowed your cast iron skillet to cool completely in the oven, allow it to cool in open air before rinsing it in water and wiping it dry. This will prevent the possibility of warping your seasoning due to thermal shock. After washing is completed, put the cast iron skillet on your stovetop or into your oven to completely dry. Forcing air into the pores of the metal will help it to avoid rusting.

If you plan on storing your cast iron, coat the inside with cooking oil and wipe dry with a paper towel to prevent rusting which can occur when cast iron is left to air dry. If rust does develop, clean off any flaking you see, re-season and rub down with some vegetable shortening to give it a protective coating. Make sure to wipe dry before using again.

Do not put anything other than water in your cast iron while cleaning. Cast iron holds onto flavors very well due to its high natural iron content – even after each use, so you don’t necessarily want tomato sauce or wine marinara running through your veins! If this means having several different pieces of cookware for different types of. Use a separate cast iron pan to cook acidic foods such as tomatoes, lemon juice or vinegar

Do not store food in your cast iron. This is a myth that was created by the Lodge Company on the packaging of their first mass-produced cast irons which read “foods will not stick if properly seasoned” – simply not true. Here is what will actually happen: Foods with high water content (eggs, pasta) can corrode and weaken seasoning layers, eventually causing your pan to rust. Lingering smells from past meals will be absorbed into future ones – you might as well season it properly next time! Teflon is safe for use on surfaces that won’t be heated above 500 degrees Fahrenheit but is not suitable for cooking. Use a cast iron pan for cooking acidic foods such as tomatoes, lemon juice or vinegar. Do not cook with a Teflon-coated pan in your oven unless it is set to a temperature below 500 degrees Fahrenheit.

Cast iron is very hard and brittle so you shouldn’t drop it or allow any sides of the pan to hit each other while cleaning. And even when seasoned properly, they’re still relatively soft pans so don’t use them as cutting boards. The longer you let your seasoned cast iron go without using it, the better your seasoning will become. Cast irons highly prized amongst professional chefs have been passed from generation to generation and are typically well over 100 years old – not because they can’t be replaced but because they’ve already been seasoned many times over and passed down to the next generation with a good cooking foundation.

A well-seasoned cast iron pan will begin to look dull after cooking acidic food such as tomatoes, lemon juice or vinegar due to their high acidity levels. However, this is normal and does not affect cooking performance in any way. Just give it a quick rinse and you’ll notice that the slight discoloration disappears! If you want an even darker finish than your initial seasoning, simply apply a fresh layer of vegetable shortening before storing away again – just make sure everything is completely dry before adding another coating.

How to remove rust from cast iron? Cast iron can be difficult to season at first until you get used to it but once properly broken in, it’s actually very easy. All you need is a bit of confidence and a willingness to get in there and get your hands dirty!

Certain foods should avoid

As you know, cast-iron pans become nonstick when you treat them with oil and heat them up. That’s why things like fried chicken and crepes cook so easily in these pans – they slide right off when they’re done. But there are some dishes that don’t work well in cast-iron pans because they can actually get stuck to the surface.

How to remove rust from cast iron?  Things You Should Never Cook in Cast Iron:

Firstly, Onions: This one is a biggie and the most surprising thing I learned in my quest for kitchen knowledge. The sulfuric acid and iron actually react together to create ferrous sulfide, which doesn’t taste good. If this happens, you can always just scrub it off with steel wool afterward. If that’s too much work, try using a stainless steel pan instead (or any other kind of nonstick pan).

Secondly, Delicate fish: Fish cooks fast anyway; there’s no need to use cast iron if you don’t want it to take on the smell and the taste of your dinner from last night (not horrible, but not amazing either). Try a nonstick pan instead.

The same heat retention that means your steak will get a beautiful brown crust in a cast iron pan will probably be the end of your lovely piece of trout or tilapia. Save the delicate fish for the non-stick pan, too. But salmon and other meaty fish that can stand the heat are fine. Try our cast iron salmon recipe for a perfectly crispy skin and flaky fish.

Thirdly, Tomatoes: The acidity in tomatoes can react with the iron, creating a tinny taste to your food – it will not kill you or anything, but it’s not great either. If you must cook something acidic in your cast-iron pan, just cook some rice first and use the pan for the tomatoes afterward (the alkalinity of the rice will cancel out any leftover acid).

Next, Anything that needs low heat: High-quality cast iron takes some time to heat up and cool down, so if you’re cooking something that needs low heat, this might be a problem for you. It’s not insurmountable by any means; do what I do and transfer whatever is cooking from the cooktop to the oven.

Fif Anything you don’t want to taste like iron: Some really acidic foods (e.g. citrus) can create a metallic taste if cooked in cast iron, so bear that in mind next time you’re cooking your favorite marinade or salad dressing — maybe try using a stainless steel wok instead.

Next, Acidic foods: As mentioned above, this was my central mistake. I would stew tomato sauces in my cast-iron Dutch oven for prolonged periods, deglaze my skillet with a pop of vinegar, or add lemon juice to foods while they were still hot on the skillet. You should avoid cooking acidic sauces in cast-iron pans for two reasons: first, the acid loosens trace amounts of molecules from the metal that can then leach into your foods, imparting a metallic flavor. While perfectly safe to consume, these metal flavors can be unpleasant. 

The second reason is that acid can cause the seasoning on a cast-iron pan to break down. The seasoned coating on a cast-iron pan is the layer of polymerized fat that comes from heating fat on the pan’s surface, and it can eventually make the pan naturally nonstick. To preserve it, avoid cooking acidic foods in your cast-iron pan for longer than a few minutes, or letting acidic foods sit in the pan for a while after cooking.

In addition, Fried Foods: Cast iron handles high temperatures but those also cause your oil to smoke faster which can affect the taste of your food. Or worse, a cracked cast iron due to exposure to very high temperature might release fumes that may not only produce a foul odor but also make you sick.

The main reason fruit doesn’t work well in cast iron cooking is because fruits have a lot of water content while vegetables don’t possess enough moisture for the same results. This means that some vegetables are more likely to get burned when cooked in cast iron while fresh fruits can end up mushy and over-cooked.

Since milk is already acidic in itself, combining it with cast iron can result in your sauce curdling which will mess up the consistency of your dish. You can still use cast iron to simmer pasta sauces but combine them externally instead of mixing everything together inside the pan. Or simply don’t use dairy products at all if you’re using cast iron; there are lots of great non-dairy alternatives nowadays!

Finally, Whatever You Cook, Avoid Storing Food in Your Cast-Iron Pan:

With a cast-iron skillet, you should always remove food from the pan and store leftovers separately. No sticking tin foil over a pan of food and just popping it in the fridge. As a general rule, you want to keep your cast-iron pan very dry to preserve its seasoning and prevent rust. The acids in food left in the pan will break down the seasoning, plus storing food in the pan for prolonged periods makes it more likely to impart metallic flavor.

One thing to note: This list is for traditional cast-iron pans. If you’ve got an enamel-coated cast iron pan, you don’t need to adhere to this list-you can just get cooking!
