Cooking in a rusted pot is generally not recommended as it can negatively affect the flavour of your food and may even cause health complications if ingested. However, experts at the University of Illinois at Urbana-Champaign note that a little bit of rust on cookware is unlikely to harm you. If you choose to cook in a rusted pot, it is important to take precautions to remove the rust and properly season the pot before use. To remove rust, you can use steel wool, an abrasive brush, or natural alternatives such as potatoes or lemons. Properly seasoning your cookware helps to create a protective barrier and prevent rust from forming in the future.
| Characteristics | Values |
|---|---|
| Is it harmful to health? | Experts say a little bit of rust on cookware is unlikely to harm you. However, ingesting rust can cause health complications for people with certain medical conditions. |
| Can it cause tetanus? | Tetanus is caused by bacteria that often collects on rusty items left outside and exposed to elements like soil and animal feces. Therefore, unless your cookware has been left outside, it's unlikely to have the bacteria that cause tetanus. |
| Can it affect food taste and quality? | Yes, it can negatively affect the flavor of your food, and food is likely to stick to the rusty bits. |
| How to remove rust? | Use steel wool, scrub with a potato, or use baking soda and vinegar. |
| How to prevent rust? | Wash and dry your cookware after every use and avoid storing it in places with elevated moisture levels. |

Potential health risks of using rusty cookware
While a little rust on cookware is not likely to harm you, ingesting rust can be harmful to those with the rare disease hemochromatosis, which causes internal organs to retain iron. The CDC also warns against inhaling large amounts of rust, which can cause respiratory issues.
It is important to note that rust itself does not cause tetanus, a potentially fatal nervous system infection. Instead, tetanus is caused by the bacteria Clostridium tetani, which is usually found in soil and animal feces. However, if your rusty cookware has been exposed to these elements, it is recommended to replace it, especially if you are not up to date on your tetanus vaccinations.
While there are no known studies showing significant health issues associated with eating food prepared in rusted cookware, some experts recommend playing it safe and replacing rusty cookware. Rusty cookware can also affect the flavor of your food.
If you wish to continue using your rusty cookware, it is important to remove the rust first. This can be done using steel wool, kosher salt, or a combination of lemon juice and salt. After removing the rust, be sure to wash the cookware thoroughly and season it with heat and oil to form a protective coating.

How to remove rust from pots and pans
While a little bit of rust on your cookware is unlikely to harm you, it may be best to play it safe and remove the rust before using the cookware again. Here are some methods to remove rust from your pots and pans:
Using Baking Soda
- Rinse the rusty pan with water.
- Cover the pan with baking soda and let it sit for an hour or more.
- Use a scouring pad to rub the rust off.
- Wash the pan and dry it with a towel.
Using Vinegar
- Spray or wet the pan with water and wipe it clean with a cloth.
- Mix equal parts water and vinegar and spray the mixture onto the pan.
- Let the mixture sit for a few minutes to soak into the metal.
- Use a scouring pad to lightly scrub along the grain of the pan to remove the rust.
- Wash with soap and water and dry the pan completely with a towel.
Using Steel Wool
- Thoroughly scrape the pan with steel wool.
- Wash with soap and water.
- Dry the pan with a towel or place it on low heat until dry.
- Pour a small amount of cooking oil into the pan and use a paper towel to coat the inside.
- Reseason the pan by placing it in the oven face down at 350 degrees Fahrenheit for one hour.
Using CLR and Vegetable Oil
- Use CLR to remove rust from the cookware.
- Rub in some vegetable oil.
Preventing Rust
To prevent rust from forming on metal cookware, avoid letting the metal air dry. Instead, use a microfiber towel to dry the pan immediately after washing. For cast iron cookware, season the pan before initial use and continue seasoning it routinely as it is used. You can also buy stainless steel cookware that contains chromium, which will help protect against rust.

Preventing rust from forming
While cooking in a rusted pot is not likely to harm you, it is still best to play it safe and prevent rust from forming in the first place. Here are some ways to do that:
Keep Items Dry
Water reacts with iron to form rust, so keeping your cookware dry is essential. Avoid leaving pots and pans in the sink or exposing them to rain. When storing them, ensure they are completely dry first. Even regular air contains moisture in the form of humidity, so consider using a desiccant or silica gel packets in your storage area to absorb any excess moisture.
Use Oil or Grease
Oil your cookware, especially if they will be stored for a long time. Oil creates a protective barrier against rust by preventing moisture from reacting with the iron in the metal. Gun owners often keep their firearms well-oiled, even when not in use, for this very reason.
Paint It
Painting metal forms a barrier that keeps corrosive elements away from the exposed steel. This method is suitable for small household items but may not be feasible for larger items that need to withstand the elements.
Cold Galvanizing Compounds
Cold galvanizing compounds are a great way to ensure the prevention of corrosion for iron and steel. These compounds contain zinc, which corrodes much slower than iron, providing a cheap and effective protective coating.
VCI Packaging
Vapor corrosion inhibitors (VCI) are chemical compounds used to protect metals from rust and corrosion. When properly stored with VCI packaging products, the VCIs fill up the vapor space inside the packaging and form a shield of protection on the metal's surface, displacing moisture and preventing rust.

Is rusty cookware unsafe to use?
While some sources claim that ingesting rust is not likely to harm you, it is still advised to avoid using rusty cookware. This is because rust can negatively affect the flavour of your food and cause it to stick to the rusty parts of the pan. In addition, if you are particularly sensitive to rust, ingesting even small quantities can cause health complications.
Rust is typically caused by exposure to moisture and is a common issue with older cookware. It is important to remove rust before using your cookware as it is not safe to eat. There are several ways to remove rust from your cookware, including using baking soda, coarse salt, white vinegar, or a rust removal product.
If your cookware is made of cast iron, you can scrub it with steel wool and warm water. For lighter layers of rust, simply using water and steel wool may be sufficient. After removing the rust, wash the cookware with soap and water, then dry it with a towel. Finally, coat the cookware with cooking oil and bake it in the oven for one hour at 350° F (177° C).
To prevent rust from developing in the first place, wash and dry your cookware after every use and avoid storing it in places with elevated moisture levels. Properly seasoning your cast iron cookware can also help keep it in safe and usable condition.

How to salvage rusty cookware
While a little rust on your cookware is unlikely to harm you, it may be best to avoid cooking with rusty pots and pans. Rust can alter the taste of your food and, in rare cases, may be a source of bacteria that can cause tetanus.
If your rusty cookware is made of cast iron, it is completely salvageable. Here are some steps you can take to remove rust from your cast iron cookware:
- First, remove all the rust with an abrasive like stainless steel sponges or an abrasive brush. You can also use a strong rust removal solution to get rid of the corrosion.
- Wash the cookware thoroughly with water and soap.
- Dry the cookware. You can do this in an oven or over low heat on a burner. Make sure it is completely dry to prevent further rusting.
- Cover the cookware with a coating of oil. This will help maintain a non-stick surface and protect the iron.
- Place the cookware in the oven and let it cool before using.
For severe rust that covers most of the cookware's surface, you can take it to a machine shop to have it sandblasted and restored to raw cast iron. However, sandblasting may alter the original surface of the cast iron.
