That oxidation will most especially present on the pan if the pan has been sitting for an extended period. Foods that are acidic or that have been washed in the dishwasher can also cause oxidation.

Putting your aluminum in the dishwasher is one of the things that will promote oxidation. Dishwashers can cause aluminum objects to rub against each other, accelerating the oxidation process and resulting in black and gray marks.

Also, anodized aluminum cookware or cookware clad in a non-reactive material, such as stainless steel or a nonstick coating, does not leach into or react with foods.

However, natural products such as lemon juice, vinegar, or cream of tartar remove discoloration quickly and effectively without harming the metal.

This process gives eggs their black color because the vessel’s top layer oxidizes during the heating process, leading to the development of black on the surface. Also, cooking food in aluminum pots increases the amount of aluminum absorbed into the food, leading to illness.

Before cooking, mix five cups of water and five tablespoons of white vinegar in the pan. While the vinegar solution in a pan is heating, the water will gradually darken to a deep, rich color. Once the black residue has been removed, pour the solution down the drain and repeat the procedure until the vinegar-water solution is clear.

Not to mention that the force of the jets can cause your pan to collide with another dishware, scratching or nicking the surface.

How to clean

  • Scrub the pan using a coarse-finish sponge or scrubber, using warm water and mild dish soap. Avoid using a metal utensil on it, as this can also damage the surface. But don’t worry if you’ve already run your pan through the dishwasher cycle—the darkening isn’t usually permanent.
  • Many commercial cleaners can be used to clean aluminum. Still, you can also make natural cleaners that are inexpensive, environmentally friendly, and effective using ingredients in your kitchen.
  • Clean the inside of an aluminum pot by filling it halfway with water. To each quart of water, add two tablespoons of cream of tartar and half a cup of vinegar. Allow the water to boil for 10 minutes, and then remove it from the heat. Next, drain the cleaner, let the cookware cool to the touch, and remove it from the heat. Wash as usual using soap and hot water.
  • Clean stubborn stains by using a steel wool pad. Lemon juice is an exceptional substitute for vinegar. Place any discolored aluminum utensils in boiling water for 10 minutes to remove the discoloration. Now that the water has been removed from the pot, they will be as clean as possible.
  • To clean aluminum, add apple peels to a pot of water and boil them for a few minutes. Next, pour enough liquid into a pot to cover the peels and bring to a boil. Slowly simmer, keeping the heat low, for 20 to 30 minutes. The acid in the apple is also responsible for giving your kitchen a pleasant scent.
