Dishwashers are wonderful appliances that securely clean almost all types of dishes, pots, and pans.
On the other hand, some pans can’t be cleaned in the dishwasher, and if they are, they run the risk of being discolored and stained.
Aluminum pans can suffer from some serious damage if placed in a dishwasher. There are two main reasons behind this— the intense heat the dishwasher uses to clean dishes and the corrosive dishwater detergent used by the dishwasher. The surface of an aluminum pan is too delicate and usually can’t withstand the combination of these two factors within the dishwasher.
As a result of the regulation in a number of states, some dishwashing businesses have been given the instruction to discontinue the utilization of phosphates within their formulation.
The capacity of phosphates added to dishwashing detergents to preserve metal surfaces is a significant advantage of this ingredient’s inclusion.
The manufacturing procedure of dishwashing soaps that does not include the use of phosphates leads in a faster yellowing of metal plates.
When cleaning most aluminum cookware, it is best to do it by hand to reduce the likelihood of the material losing its original color and texture.

Types of Aluminum Cookware
Cookware made of aluminum has been available for some time now. Since its beginning, it has undergone a process of significant development and advancement.
More than half of all the cookware that is purchased is made of aluminum, making it one of the most widely used materials for making cookware.
In terms of conductivity, cookware made of aluminum is a close second to copper. It is highly recommended that you read the label before making a purchase of cookware of this kind.
On the market, you can find many different varieties of cookware made of aluminum, including pressed, cast, and anodized varieties.
The most cost-effective option is cookware made of pressed aluminum. Its thin construction and screw-in handle are two of its most appealing features. This material is used to manufacture the vast majority of kitchenware made of aluminum.
However, the handles become dislodged or completely fall off of these utensils in a very short amount of time, so their lifespan is limited.
Cookware made of pressed aluminum deteriorates very quickly and is likely to sustain damage straight away if it is left in a dishwasher for an extended period of time.
Aluminum casting is a time-consuming and expensive process, but the finished product is well worth the investment. The finished product is more substantial than cookware made with pressed aluminum.
As an added layer of defense, the bottom of a cast aluminum pan has a greater thickness than the sides.
Because cast aluminum is more porous than pressed aluminum, cast aluminum pans offer better heat retention than pressed aluminum pans.
Cookware that is made of anodized or hard-anodized aluminum is of the highest quality. This is the kind that everyone ought to be selecting as their option.
This particular variety of cookware made from aluminum is scratch-resistant and does not cause food to adhere to it. Anodized aluminum cookware has a surface that is much more durable than steel.
Although this type of cookware typically has a higher price tag than others, the investment is well worth it.
Cookware made of anodized aluminum is comparable in quality to that made of stainless steel, cast iron, and copper, all of which are considered to be of the highest quality. The anodized aluminum pans have a distinct gray finish, which makes them easy to identify.
However, the gray finishing on the pans is easily damaged in the dishwasher due to its high level of abrasion resistance.
Cookware made of cast aluminum, such as pots and pans, is heavier and more substantial than cookware made of pressed aluminum. However, cast aluminum cookware typically has a delicate finish, which renders it completely unsuitable for use in dishwashers.
Dishwashers and Aluminum Cookware
Adding stainless steel cookware or aluminum pans in the dishwasher puts you on a path to disaster, especially if the item isn’t pretreated to be washed in a dishwasher.
Any aluminum pot, baking sheet or roasting pan that has been anodized can often become pitted or can corrode due to the harsh detergent properties.
The alkalinity of the detergent can cause white spotting on the surface of the aluminum cookware.
If the cookware has been darkened after being in the dishwasher, then the best way to bring it back to its normal state is by using natural astringents and cleaners.
Dishwasher Safe Symbol
You should be able to find symbols on your cookware and dishes that indicate they can withstand any kind of heat or cleaning solution. These symbols will be easy to spot.
You can tell whether or not a pot, pan, or utensil made of aluminum is safe to put in the dishwasher by looking for symbols that are imprinted on the rim or base of the item.
You are now able to wash your cookware in light of this information. In light of the fact that not all symbols are acknowledged or accepted on a global scale, it is recommended that you wash any items of cookware by hand if you are still unsure about whether or not they should be put in the dishwasher.
A sign depicting a shower with angled lines indicates that the pot or pan can only be placed on the top rack of the dishwasher in order for it to be cleaned by the dishwasher.
When looking for dishes or cookware, look for a symbol that depicts a plate in the rack with water drops slanting over the top in the shape of a small rectangle. This signifies that the dish can easily withstand the high heat of a standard dishwasher.
Before you put your cookware in the dishwasher, be sure to recall these warning signs and keep them in mind.
Advice on Putting Aluminum Pans in the Dishwasher
Make sure you read the directions that are provided by the manufacturer on the box of a pan before you put it in the dishwasher. This will let you know whether or not the pan can be cleaned in a dishwasher.
Always be sure to follow the instructions given by the manufacturer, since doing so will help you save money in addition to safeguarding the other items in the dishwasher.
Because it takes time for the surface to break down and for tarnish to build on it, the damage that has been done to aluminum pans may not be particularly noticeable right away.
This indicates that you may, if you so want, run the aluminum pan through the dishwasher once before deciding whether or not it is safe to use. Having said that, it is strongly recommended that this not be done.
It’s best to err on the side of caution and avoid washing any kind of aluminum cookware in the dishwasher, including pans.
The dishwasher will very certainly cause damage to the aluminum utensils, no matter what sort of metal they are.
Even if you don’t mind if your flimsy aluminum pans get damaged, you shouldn’t put them in the dishwasher because as they move around during the cycle, they can cause damage to the items and dishes that are in close proximity to them.
On the other hand, pots, pans, and cookware made of stainless steel may be cleaned in the dishwasher; however, before doing so, it is important to read the instructions provided by the manufacturer.
If you’re not going to put the pots and pans in the dishwasher right away, at least give them a quick rinse.
The Environment of the Dishwasher
Dishwashers are capable of heating water to temperatures higher than 140 degrees. For the dishes to be effectively cleaned, the environment that is created inside of a dishwasher is absolutely necessary.
It is essential for there to be heat inside the dishwasher in order for the detergent to melt and for any grease or grime that has adhered to the dirty dishes to be removed.
The dishwashing detergent also includes some very harsh chemicals, which are included to help the detergent do a better job of cleaning the dishes.
Aluminum pans are left with hazy stains that are very difficult to remove after being washed in the dishwasher with hot water and a harsh dishwashing detergent because of the combination of the two factors.
Proper Cleaning of Aluminum Pans
Cookware made of aluminum, such as pots and pans, can undergo a reaction and darken when washed in a dishwasher due to the high mineral content of the hot water, the harmful chemicals of the detergent, or the high heat from the dish dryer. These factors can all contribute to the reaction.
Aluminum pots, pans, or other items of cookware that can’t go in the dishwasher need to be hand washed in the kitchen sink using a gentle dish detergent and warm water instead.
When working with aluminum pans, you should avoid using any kind of abrasive pad or hard scraper because doing so can scratch the surface of the pans.
These pads or scrapes, unless they have been approved by the manufacturer, have the potential to scrape or scratch the metal as well as the non-stick coatings.
After being washed, the pots and pans need to have a thorough final rinse.
If your aluminum pans are unfortunate enough to meet an unfortunate end and become tarnished, you can remove the discoloration by using natural elements such as lemon juice, vinegar, or tartar cream. This will allow you to achieve speedy and excellent results without causing any damage to the metal.
When it comes to removing tarnish from aluminum cookware, acidic substances such as lemons are an excellent choice. After having been cleaned in the dishwasher, your damaged aluminum pan can be cleaned in the following manner:
- Water should be used to start the process. To nearly reach the maximum capacity of the aluminum pot or pan, fill it with water. Just make sure that there is just enough room left over so that the water does not boil over onto the stovetop, which would result in a significant amount of mess.
- Add three tablespoons of lemon juice, white vinegar, or cream of tartar for every quarter cup of water that you are working with. After allowing the solution to boil for around ten minutes, remove it from the heat source and then strain it.
- Consider using a pad made of steel wool that has been dipped in warm water. Now make use of it to remove any mineral layers from the surface of the pot or pan that have lifted as a result of the boiling procedure. It is important to thoroughly rinse the aluminum pan or pot in order to remove any trace of soap that may still be there.
- Take a dry towel and wipe the inside and outside of the pan to ensure that it does not retain any moisture.
You can also apply the metal polishing paste to the area of the aluminum pan that has become oxidized. Not only will it remove any oxidation that may have formed on the surface of the aluminum pan, but it will also make the surface of the pan shine.
Simply apply some to the area that has become oxidized, and then wait for it to work its wonders.
Problem Stains on Aluminum Pans
If the pans have food or grease that has burned on them, you will need to scrape out as much of the food as you can using a spoon or a spatula.
For those food items that are exceptionally challenging to remove, a wooden spoon is an excellent tool to have on hand.
After you have finished scraping, you should fill the pan with hot water and leave it in that state for approximately one hour.
Bringing the cleaning process to a close, wash the pan using some warm soapy water and a sponge.
After that is done, wipe the pan down with a fresh cloth so that it does not become stained over time.
Additional Tips when cleaning aluminum pans:
- If you want to wash your aluminum pots and pans in the dishwasher without leaving any stains, you may want to consider switching up the dishwashing detergent that you use. You might opt for one that does not include bleach and is kind to the environment. You may get your hands on such detergents at any supermarket that sells healthy foods or organic produce. You should consider using a detergent that is rich in enzymes as one of your options.
- Cleaning cookware made of aluminum by hand in the sink is the most effective approach to remove any stains that may have formed on the surface of the metal. Make sure that the dishwashing liquid you use has a pH that is neutral. The vast majority of dishwashing detergents are alkaline, which may cause aluminum pans to become more discolored.
- Check to check if your anodized aluminum pan has any traces of gold or copper and see if you can find any. If it looks like copper or gold, then you shouldn’t wash it in the dishwasher since there is a good risk that the coating will be lost. This means that it won’t be safe for use in the dishwasher.
- Even while salt may be used as a mild abrasive to clean in place of a piece of wool, we strongly recommend that you exercise extreme caution when doing so. Only specific things may be utilized, and cookware made of aluminum should never be used with salt since it can create major pitting in the surface of the metal. Steer clear of any suggestions that encourage you to clean your aluminum pan by scrubbing it with salt.
- Aluminum cookware is not only inexpensive but also an excellent heat conductor; nonetheless, it has the potential to get discolored if it is subjected to certain chemicals, minerals, or environmental conditions. It’s possible that putting aluminum pans in the dishwasher can ruin them, so try to avoid doing that. When combined, the extreme heat of the dishwasher and the mineral content of the water may cause metal cookware to become discolored.
The Bottom Line
If you put aluminum pans in the dishwasher, there is a possibility that they will be damaged in some way. This is the bottom line.
Anodized aluminum cookware can be quite pricey, and you don’t want to have to keep shelling out significant sums of money to replace your anodized aluminum pan.
As a result, you need to exercise caution before putting it in the dishwasher. Second, if you have any pressed or cast aluminum pans, placing them in the dishwasher with your other dishes and utensils could result in damage to those items.
If you are concerned about the condition of your aluminum cookware, the best course of action is to keep it out of the dishwasher when you clean it.
Why does the dishwasher discolor aluminum pans?
Aluminum pans, much like cast-iron cookware, should under no circumstances be put in the dishwasher. According to Jennie Varney, brand manager for Molly Maid, “the combination of alkaline dishwasher detergent, high heat, and minerals in your water can trigger a reaction that darkens the metal.” [Citation needed] “The reaction can darken the metal,”
How do you restore aluminum discolored in a dishwasher?
Cookware made of aluminum may undergo a reaction and darken as a result of being washed in a dishwasher due to the presence of minerals in the water, chemicals in the detergent, or high heat from the dryer. Natural products such as lemon juice, vinegar, or cream of tartar can be used to remove discoloration quickly and effectively without causing any damage to the metal.
What causes aluminum to corrode in a dishwasher?
Aluminum, in contrast to many other metals, is amphoteric, which means that it can be dissolved in both strong bases and strong acids. The pH of most dishwashing detergents is probably somewhere around 11 or 12, and they are mostly alkaline. Together with the heat, it might be enough to corrode the aluminum. Strong acids, but not alkalis, are able to dissolve the vast majority of the other common metals.
How do you fix an aluminum pan that has been washed in the dishwasher?
In a spray bottle, combine white vinegar and water in the same proportions. Applying the solution to the aluminum in a spray form. It only takes a few minutes to soak, and then you can scrub it with steel wool. While you are scrubbing, feel free to add more of the vinegar solution as you see fit.
Is oxidized aluminum cookware safe?
Although the majority of cookware made of aluminum is safe to use because it has been oxidized (a process that prevents the aluminum from leaching into your food), aluminum in its pure form presents a different set of challenges. Because it has not been oxidized, there is a significant possibility that it will leach, particularly when it is subjected to extremely high temperatures.
