Rust is a common issue with cookware, and it can be harmful if consumed. It occurs when iron and oxygen meet, and water is a key factor in this chemical reaction. Cast iron pans are particularly prone to rusting, but even stainless steel can rust if not cared for properly. Rust can ruin your pans, but the good news is that it can be removed. There are several methods to clean rust off cookware, including using coarse salt and oil, baking soda, or vinegar. Once the rust is removed, it's important to dry the pan thoroughly and reseason it to prevent rust from forming again.

What You'll Learn

Use a mixture of coarse salt and oil
Griswold pans are made of cast iron, which is prone to rusting when left in humid or moist environments for extended periods. The good news is that rust can be cleaned off, and your pan can be restored to its original condition.
One popular method for removing rust involves using a mixture of coarse salt and oil. Salt acts as a gentle abrasive, scrubbing away the rust without damaging the pan's surface. To use this method, start by pouring a mixture of coarse salt and a neutral cooking oil, such as canola or grapeseed, onto the rust spot in a 1:1 ratio. Using a circular motion, scrub the mixture into the surface of the pan with a paper towel or soft cloth until the rust is removed. You may need to use a coarse scrubber, such as a scouring pad, steel wool, or an abrasive sponge, for more stubborn rust.
Once the rust is removed, rinse the pan with water to remove any salt residue. It is important to dry the pan immediately and thoroughly, using a towel first and then placing it on a stove over low heat to ensure it is completely dry.
After removing the rust, it is essential to re-season the pan to restore its protective layer and prevent future rust. Apply a thin layer of oil and bake the pan in the oven at 350°F (177°C) for about an hour. This process will create a non-stick surface and help maintain the pan's condition and functionality.
Using a mixture of coarse salt and oil is an effective and gentle way to remove rust from your Griswold pan, but it may require some elbow grease, especially for larger rusted areas. With some time and effort, your pan will be rust-free and performing as good as new.

Apply vinegar and water
To clean rust off a cast-iron pan using vinegar and water, you'll need to start by creating a solution of equal parts vinegar and water. Use distilled white vinegar for this purpose. Fill a container that is large enough to completely submerge your pan with this solution. A plastic bin or a large casserole dish can be used for this purpose.
If you have rust only on the interior of your pan, you can fill it with the vinegar solution rather than submerging the whole pan. You will eventually hear the solution fizzing, which means it's working. Check the pan after an hour to see if the rust has been mostly removed or has become thin enough to scrub off. If the pan needs more time, return it to the solution, but do not leave it submerged for more than 24 hours, or you could damage the pan.
Remove the pan from the solution and immediately rinse it with running water. If you see flash rust, a thin layer of rust that develops as soon as you remove the cast iron from the vinegar solution, don't worry. Make a slurry of Bar Keepers Friend and a couple of tablespoons of water in the pan and scrub any remaining rust off using a stainless steel scrubber.
After removing rust from your cast-iron skillet, you must re-season it to restore the protective layer of fat molecules that bind to the pan, creating the cast iron's non-stick surface and signature dark matte finish.

Try baking soda
Baking soda is a mild abrasive that can be used to remove rust stains from your Griswold pan without causing any damage. It is readily available in every household and is a good alternative to harsh chemicals.
Before you begin, ensure that you have a generous amount of baking soda on hand, as well as a scrubbing pad and some water. You may also want to have some vinegar handy, as this can be used in conjunction with baking soda to increase its effectiveness.
Start by applying water to the rusty areas of your Griswold pan. Sprinkle a generous amount of baking soda onto the wet spots. The baking soda should stick to the damp areas. Gently tap the pan to remove any excess.
Wet your scrubbing pad with water and gently scrub the baking soda-covered areas of the pan. Keep the scrubbing pad wet to reduce scratching on the metal surface. When most of the baking soda has dissolved, sprinkle on some more and continue scrubbing until the surface is free of rust.
If the baking soda alone does not remove all the rust, you can try adding vinegar to the mix. First, rinse the pan with water to remove any remaining baking soda. Then, spray or wet the pan with a mixture of equal parts water and vinegar. Allow the vinegar mixture to sit for a few minutes so that it can soak into the metal. Use a scouring pad to lightly scrub along the grain of the pan to remove any remaining rust.
Finally, wash the pan with soap and hot water and dry it thoroughly with a towel. You can also place the pan on low heat for a few minutes until it is completely dry. To prevent rust from forming again, rub a thin coat of oil on the inside and outside of the pan.

Season the pan
Griswold cast iron manufactures a variety of cookware that is often collectible. Here is a detailed guide on how to season a Griswold pan:
Seasoning a pan is essential to prevent rust from forming on cast iron. Seasoning creates a natural protective coating on the metal. Firstly, it is important to wear rubber gloves and eye protection while seasoning a pan, as some methods require the use of caustic chemicals.
To season a pan, start by warming it in the oven for a few minutes. Then, take it out of the oven and apply a thin, even layer of fat or oil to the surface. You can use shortening, vegetable oil, lard, bacon fat, or any cooking oil. Use a paper towel or cloth to rub the fat or oil into the surface of the pan in a circular motion, ensuring that the entire surface is coated.
Place the pan back in the oven, upside down, and bake at 350°F for an hour. Turn off the oven and let the pan cool completely inside. This process will create a natural non-stick surface on your Griswold pan.
If you want to season multiple pans or a large batch of cookware, you can use a soaking solution of 1 1/2 gallons of water mixed with one can of lye in a plastic container. Soak the items for about five days, then scrub them clean with a brass brush. After cleaning, the items should be seasoned as described above.

To use this method, attach the fine wire wheel to a drill or angle grinder. Then, gently work the wire wheel over the rusted areas of the pan until the rust is removed. It is important to be careful when using a wire wheel, as it can fling rust and carbon dust.
After removing the rust with the wire wheel, it is important to rinse the pan thoroughly and then re-season it. You can use a mixture of vinegar and water, or a lye bath, to remove any remaining rust or residue. Be sure to wear protective gear when handling lye, as it can be harmful to your skin and eyes.
Overall, using a fine wire wheel can be an efficient way to clean rust off a Griswold pan, but it is important to take the necessary precautions to ensure safety and effectiveness.
