Aluminum pans are not dishwasher-safe. The combination of alkaline dishwasher detergent, high heat, and minerals in the water can trigger a reaction that discolours and damages the metal. Luckily, there are several methods to restore the shine of your aluminum pans. One method involves hand washing the pan with a mild dish soap. Another method involves using a white vinegar solution, lemon juice, or a cream of tartar paste. It is important to avoid using abrasive materials that may scratch the surface of the aluminum.

Hand wash aluminium pans with mild dish soap and a non-abrasive sponge
Aluminium pans are sensitive to harsh detergents, and most dishwasher detergents are alkaline in nature. This can cause the pans to become discoloured, dull, or develop white spots. Therefore, it is best to hand wash aluminium pans with mild dish soap and a non-abrasive sponge.
Firstly, fill your sink or a basin with warm water. Add a few drops of a mild dish soap and mix gently to form a soapy solution. Place your aluminium pan in the soapy water and let it soak for a few minutes. This will help loosen any stuck-on food particles or grime.
Next, use a non-abrasive sponge or a soft cloth to gently clean the pan. Avoid using excessive force or abrasive materials, such as steel wool, as these can scratch the surface of the aluminium. Use gentle circular motions to remove any stains or discolouration.
Once you have finished cleaning the pan, rinse it thoroughly with clean water to remove any soap residue. Dry the pan completely with a soft cloth to prevent water spots or streaks. Ensure that your pan is thoroughly dried before storing it away.
If your pan has accumulated tough, burnt-on grime, you may need to use a more abrasive cleaning method. You can create a paste by mixing baking soda and water and applying it to the stained areas with a soft-bristled brush. After cleaning, always rinse and dry your pan thoroughly.

Soak pans in a mixture of baking soda and water
If your aluminium pans have been damaged by the dishwasher, there are a few things you can try to restore them. Firstly, it's important to note that aluminium doesn't belong in a dishwasher that uses conventional alkaline detergents, as they will destroy the metal.
One method to try is to soak your pans in a mixture of baking soda and water. This can help to remove lingering food smells and flavours, as well as acting as a mild abrasive to clean stubborn stains and scorched oil. Here's how you can do it:
Firstly, cover the bottom of your pan with a layer of water. Then, sprinkle baking soda liberally over the water to create a thin paste. You can add more water or baking soda to get the right consistency. Let the pan sit for several hours, then rinse and wash the pan with a non-stick-safe nylon scrubbing brush. For more stubborn stains, you can try boiling a solution of 4 tablespoons of baking soda and 1/2 cup of water in the pan. Allow the pan to cool, then rinse with straight baking soda and scrub with your brush.
For really tough, years-long residue, another option is to sprinkle the pan with baking soda and add 2 tablespoons of water to make a slurry. Let this sit for 30 minutes, then scrub away the residue with a sponge or brush.
You can also try adding vinegar to the mix, as the bubbling and fizzing will help to remove food and residue. Combine 1 cup of hot water and 1/3 cup of vinegar, then add 2 tablespoons of baking soda. This solution can be left to soak for a few hours, and you can scrape the surface with a spatula before scrubbing.
Remember to always allow your pans to cool before washing them, as hot pans can warp if submerged in cold water. Thoroughly dry your pans after cleaning and, for cast iron pans, rub the surface with oil and heat in the oven at 400 degrees Fahrenheit for an hour.

Use a vinegar solution to remove stains
If your aluminum pan has been damaged by the dishwasher, it may be possible to restore its appearance. The darkening of aluminum cookware is usually not permanent and can often be reversed.
One method to remove stains from aluminum cookware is to use a vinegar solution. Combine equal parts white vinegar and water in the pan and allow it to soak for several hours or overnight. The acidity of the vinegar will help to loosen and remove the stains. After soaking, use a non-abrasive sponge or cloth to gently scrub the stained areas. Rinse the pan with warm water to remove any remaining residue and ensure that it is completely dry before storing it.
Another method to remove stains is to create a paste by mixing baking soda with a small amount of water until it forms a thick consistency. Apply this paste to the stained areas and let it sit for approximately 30 minutes. Then, use a sponge or soft brush to scrub the stains. Rinse the pan with warm water and ensure it is completely dry before storing.
Additionally, you can fill the pan with water and add 2 tablespoons of cream of tartar per quart of water. Bring the water to a boil and let it simmer for about 10 minutes. Remove the pan from the heat and allow it to cool before washing it as usual. This method is effective in removing stains and brightening the aluminum.
It is important to note that aluminum cookware should be washed by hand using mild soap and a non-abrasive sponge to prevent staining and discolouration. Harsh detergents and high heat from the dishwasher can damage the aluminum, causing it to darken and discolour.

Lemon juice can be used to remove discolouration
Firstly, it is important to note that aluminium pans should not be put in the dishwasher. The high temperatures and alkaline detergents can damage the metal.
To remove discolouration, mix two tablespoons of lemon juice with a quart of water. Boil this mixture in the aluminium pan for 10 minutes. Discard the mixture and wash the pan with mild dish soap and warm water. Use a non-abrasive scrubbing pad to remove any remaining stains.
Lemon juice can also be used to clean smaller aluminium utensils. Place the items in a pan and add lemon juice. Briefly bring this to a boil and leave the items in the hot water for a while. Wash the items with mild dish soap and water and dry them with a soft cloth.
Other natural alternatives to cleaning aluminium include using apple peels, vinegar, and cream of tartar.

Cream of tartar can be used to remove white spots
If your aluminum pans have developed white spots after being washed in the dishwasher, you can remove these spots using cream of tartar. The white spots are caused by the harsh, alkaline dishwasher detergent, which corrodes the oxide layer on the pans.
To remove the spots, mix cream of tartar with warm water to form a paste. Using a medium-coarse rag, rub the paste over the pan in a circular motion, paying extra attention to the white spots. After wiping for about 30 seconds, rinse the pan under cool water.
Alternatively, you can boil a solution of two to three tablespoons of cream of tartar in a quart of water for 5 to 10 minutes. Lightly scour the pan with a soap-filled scouring pad afterward.
You can also use lemon juice or vinegar as an alternative to cream of tartar. All three options are acids, which are effective at removing the white discoloration.
