Cast iron cookware is a favorite of mine. When given the chance, I recently utilized my entire carry-on allotment to bring a new skillet on a flight.

Needless to say, I am a fan.

With this in mind, I strongly advise you not to put your cast iron cookware in the dishwasher (cast iron pans are not dishwasher safe).

I get that placing your cast iron in the dishwasher is simple and enticing, but it ignores the advantages of using cast iron in the first place.

Dishwasher Ruins Cast Iron Pan Seasoning

To begin with, dishwashers destroy the seasoning of your cast iron cookware.

One of the key advantages of cast iron over other forms of cookware is the seasoning that comes with continuous usage.

You should season your cast iron cookware before using it for the first time (more on that below). Cast iron cookware is porous and resembles a brick more than ceramic or stainless steel cookware.

As a result, it has a tendency to keep what you put into it.

When pan-frying a steak after cooking bacon earlier in the day, retention is beneficial. Not good if you’ve washed your skillet and soap residue is now leaking into your filet.

Begin by rubbing kosher salt into your cast iron and cleaning it clean. Then repeat with a little quantity of oil, wiping it clean with a paper towel or cloth afterward.

The salt and oil will season the cookware and produce an almost nonstick surface that will make cleanup a breeze.

Placing your cast iron cookware in the dishwasher is dangerous for two reasons.

  • Initially, it will flood the porous material with hot, soapy water. This is not something you want to use as a marinade for your next dinner.
  • Second, it will remove the seasoning that has gradually built up over time. Cooking fatty pieces of beef and bacon traps the taste in the skillet’s surface.

The resultant glaze not only offers a superb cooking surface but also gives a subtle sense of flavor to any food.

Don’t squander it by putting your cast iron cookware in the dishwasher.

Cast Iron can Soak Dishwasher Soap

Cast iron is also commonly recognized as more chemical-free and safer than other forms of cookware.

Leaching may occur while cooking at high temperatures.

Metals from cookware are absorbed into the food via leaching. Aluminum, for example, has a greater probability of this happening and may have significant health consequences.

According to studies, cast iron is resistant to leaching, and when it does occur, it just enriches the meal with more of what our bodies naturally need, iron.

When you use the dishwasher to clean your cast iron, chemicals are introduced into the material that are subsequently released when you cook.

Even if all that is absorbed is soap residue, why take the risk if you wouldn’t put it in your food while you cook it?

How To Clean Cast Iron Pans (without using a dishwasher)

Cleaning your cast iron skillet or pan is simple.

By following the four procedures outlined below, you may ensure a long and happy relationship with your favorite cookware.

Cleaning Begins With Cooking

Then, before you begin cooking, thoroughly prepare your skillet. Heat a tiny quantity of water in your cast iron pan until it starts to steam.

Remove from the heat, pour off the water, and clean it with a paper towel or clean cloth.

By heating and wiping off cast iron, any residual film or residue is removed from tonight’s supper.

Pre-heating Is Key

After that, reheat the cast iron and add any fat or oil you want to use for cooking.

While cast iron will never be as nonstick as Teflon, this simple procedure will make cleanup a breeze.

Cool and Wipe

Let the pan to cool before wiping it off with warm water and any mild scrubbing brush you have on hand.

If there is still food residue on the pan, simmer a little quantity of water in the pan for around five minutes.

This will assist release the food and make cleaning simpler.

Others may disagree, but it is fine to use a tiny bit of soap to thoroughly clean the pan.

If any soap or detergent enters the porous surface of the cast iron, it will be eliminated during the preparation step the next time you use it.

Dry the Cast Iron Pan Properly

Cast iron is a metal that rusts fast. After washing your pan, ensure sure it is completely dry.

You may clean it with a lint-free towel and even return it to the burner to allow the stove to perform its work.

Any talk on cleaning would be incomplete without including how to season your cast iron.

The last step in cleaning is to reseason the pan.

Rinse and Reseason

It is vital to reseason your cast iron on a regular basis.

Because of its capacity to keep seasoning, cast iron is ideal for cooking.

Cast iron, unlike porcelain or aluminum, is permeable and may retain seasoning from meal to meal.

As a result, before using cast iron for the first time, many people season it with salt and oil.

Begin by sprinkling a little quantity of salt over the pan’s surface. Then, apply an oil to the area, such as grapeseed or olive oil, and wipe away any excess.

The salt and oil cover the small pores of your pan, adding flavor and protection.

Lastly, lay your cast iron skillet or pan in the oven upside down. Bake it for 10 to 15 minutes on medium heat to trap the oil and fully seal it.

A baking sheet should be placed under your cookware to capture any oil that may leak and keep your oven clean.

This adds the seasoning that only cast iron can give while also protecting the pan’s surface. Cast iron will never be as smooth as Teflon, but if properly cared for, it will endure for decades.

The pan is properly protected and ready to use after this last stage in the cleaning procedure. Utilizing a dishwasher to clean your cast iron would negate all of your efforts.


The Rocky of cookware is cast iron. It can withstand a pounding and keep running. The use of cast iron dates back to the Han period circa 200 BC.

Since its invention in 1707, the technique for producing cast iron has remained unchanged. Cast iron is built to endure, and there is evidence that it will if properly cared for.

It’s a wonderful tradition to pass along family recipes.

If you take care of your cast iron cookware, your family will not only utilize the same recipes for centuries, but will also make them in the same pan.

On weekends, my family looks forward to waking up to the smell of pancakes in our skillet.

I am relieved to hear that they will use the same skillet to feed their children with caution. I’ll simply have to remind them not to put it in the dishwasher.
