Benefits of Cooking in a Cast Iron Skillet

Cast iron pans are an excellent choice for anyone who wants to cook healthy meals. They are non-stick, meaning that you don’t need to use any oil or butter when cooking.

This makes them an excellent option for people trying to lose weight or eat healthier.

Drawbacks of Cooking With a Rusty Cast Iron Pan

The biggest drawback of cooking in a rusty cast iron pan is that it can be dangerous. The rust can flake off into your food, which you then ingest.

This can cause stomach problems and other health issues. In addition, the rust can also transfer to your cookware, which will eventually ruin it.

If you are going to use a rusty pan, you must take the necessary precautions to avoid these dangers.

Is Rust on Cast Iron Pans Dangerous?

Normally, a little rust on your cast iron pan is not dangerous. It should be fine if you clean the pan nicely and then cook in it.

While rust can change the taste of your food, it should be harmless.

What’s not ok is to have a pan that has a lot of rust, and the rust can chip and get ingested with food. Heavily rusted pans with small pores or chips can also harbor bacteria which can come into your food if cooked in it.

US Department of Agriculture recommends throwing away food in heavily rusted cans. It also recommends cleaning cast iron cookware that have rust and only then using them for cooking.

Why Do Cast Iron Pans Become Rusty?

One of the downsides of cast iron pans is that they are prone to rust.

Rusting happens when moisture gets into the pores of the metal, causing it to corrode.

The main reason why this occurs is that cast iron pans are not treated with any sealant or finish. Water and other liquids can easily damage them because of this.

How Fast Do Cast Iron Pans Rust?

Cast iron skillets can rust relatively quickly – especially if they are not correctly cared for.

So if you live in an area with high humidity or often use your pan for cooking acidic foods, it’s essential to check the pan regularly for signs of rust.

If you allow the rust to accumulate, it will eventually eat through the metal and ruin your pan.

How To Clean and Season a Cast Iron Pan

One of the best things about cast iron pans is that they are very easy to clean. All you need is some hot water and a scrub brush – no soap necessary!

Once your pan is clean, it’s important to season it to prevent future rust.

To do this, coat the pan with a layer of vegetable oil and bake it in the oven for 30 minutes (the oven should be preheated at 400-450° F).

This will help form a protective layer coating on the pan’s cooking surface.

You can then place the pan upside down to remove any excess oil (while the oil that formed the protective layer would stay in place). Put aluminum foil at the bottom of the oven to collect any oil that will drip from the pan

Is There Any Other Way I Could Season My Cast Iron Rather Than Using Vegetable Oil?

There are several different ways that you can season your cast iron pan. One popular method is to use flaxseed oil – this will help form a protective coating on the pan’s surface.

Another option is to use lard or bacon grease – both of these will help create a non-stick surface. Finally, you can also use coconut oil, which has antibacterial properties.

Whichever method you choose, make sure to season your pan after each use. This will help to prevent rust from forming in the future.

How To Remove Rust From a Cast Iron Pan

If your cast iron skillet has become rusty, don’t worry – it’s not the end of the world! You can remove rust from a cast iron pan using simple household ingredients.

Here are the things you will need:

  • Coarse Kosher Salt
  • White vinegar
  • Water
  • Dish soap
  • Steel wool or scouring pad

Remove as much rust as you can by scrubbing with a wire brush. This will also give you a chance to check for any cracks in the pan.

If there are any cracks, you should not use the pan and instead replace it with a new one.


Fill the pan with enough cold water to cover the rust. Add one tablespoon of coarse salt for every quart of water. Stir until the salt dissolves.

Bring the mixture to a boil over high heat, then reduce the heat to medium-low and simmer for 30 minutes.

Remove the pan from the heat and pour in white vinegar. The vinegar will help to break down the rust.

Let the pan cool, then pour out the liquid. Next, soak the pan in warm water until all rust has been removed.

Apply a thin layer of dish soap to a steel wool pad or scouring pad, and scrub until all the rust is gone.

Rinse the pan with hot water and dry it thoroughly with a paper towel. Season the pan using a light coating of vegetable oil or cooking spray.

Place it in a preheated oven at 350 degrees Fahrenheit for one hour. Let it cool completely before storing.

Tips for Preventing Your Cast Iron Pan From Rusting

There are a few simple things you can do to prevent your cast iron pan from rusting.

First of all, make sure to clean it after each use. This will help remove any moisture or food particles that might be on the pan’s cooking surface.

Secondly, season your pan regularly – this will create a barrier that will prevent moisture from getting into the pores of the metal.

Finally, store your cast iron pan in a dry place – this will help keep it free from rust-causing moisture.

Can You Get Tetanus From Food Cooked in a Rusty Cast Iron Pan?

There is no risk of getting tetanus from food cooked in a rusty cast iron pan. Tetanus is caused by bacteria that are present in soil and manure.

Since cast iron pans are not porous, they do not provide a hospitable environment for these types of bacteria to grow.

If, however, you get pierced or cut by any rusted object, you should see a doctor immediately as there is a risk of infection.

When To Throw Away a Rusty Iron Pan?

If your pan is only slightly rusty, you can try cleaning it with a steel wool pad or scouring pad.

However, if your cast iron pan is severely rusty, it’s best to throw it away and start fresh. In addition to being difficult to clean, severely rusted pans can often leave food tasting metallic.

Furthermore, cast iron pans are relatively inexpensive, so there is no reason to take risks with your health.

If you’re not sure whether or not your pan is salvageable, it’s always best to err on the side of caution and get a new one.

Is It Safe to Cook in a Rusty Cast Iron Pan? The Verdict

Cooking with a rusty cast iron pan is perfectly safe – as long as you take some precautions.

Make sure to clean your pan with hot water and a scrub brush, and season it regularly to prevent bacteria from growing.
