What You'll Learn
Use bleach and sunlight
Aging aluminum pans can be done in several ways, one of which is by using bleach and sunlight. This method can give your aluminum pans a cool, distressed, and aged look. Here is a step-by-step guide on how to achieve this effect:
Prepare the Aluminum Pan
Before applying any chemicals, it is essential to prepare the surface of the aluminum pan. Using fine grit sandpaper, sand the pan to roughen and distress the surface. This step will help the bleach react with the metal. You can choose to do this by hand or use an electric sander, depending on the size and extent of the project.
Apply Bleach
When working with bleach, it is important to take safety precautions. Wear protective gear, such as a mask and gloves, and ensure that you are working in a well-ventilated area to allow fumes to disperse easily. Prepare a spray bottle with regular bleach, and generously spray the aluminum pan. Make sure to cover all the areas you wish to age.
Sun Exposure
After spraying the pan with bleach, place it in direct sunlight for several hours. Sunlight plays a crucial role in this process, as it speeds up the chemical reaction between the bleach and the metal. The sun's rays will help the bleach corrode and dissolve parts of the metal, creating an aged appearance.
Rinse and Clean
Once the pan has been exposed to the sun for a sufficient amount of time, it is important to remove the bleach. Rinse the pan thoroughly with running water to ensure no bleach residue remains. If your pan has electronic parts or other elements that prevent submersion in water, use a clean, white cloth to wipe away any bleach. You can also submerge the pan in a container of water for several minutes to ensure all bleach is removed.
Final Steps
After rinsing, you may notice that your pan has taken on a darker or even blackened appearance due to the reaction with bleach. If you wish to enhance the aging effect further, you can repeat the process, wrapping the pan in aluminum foil and running it through the dishwasher with detergent and trisodium phosphate. This additional step is optional but can intensify the aged look.
Using bleach and sunlight is an effective way to age your aluminum pans and create a unique, distressed aesthetic. Always remember to prioritize safety when working with chemicals and enjoy the transformation process!

Sandpaper to distress
Sandpaper can be used to distress and age aluminum pans. This method can also be used to clean the pan if it is dirty. Firstly, you should use 80-grit sandpaper to rough up the surface of the metal. This can be done by hand or with an electric sander, depending on the size of the pan. If you are working with a large pan, it is recommended to use an electric sander to save time and energy.
After sanding, you can spray the pan with bleach and leave it in the sun for several hours to achieve an aged look. Alternatively, you can soak the pan in cold water and an oxygen-based cleaner to create aging and patterns. If you wish to stop at the sanding stage, you can simply wash and rinse the pan thoroughly to remove any residue.
If you are using sandpaper to clean your pan, it is recommended to use wet sanding paper, the kind used in auto body shops. Place the pan in the sink and run a small stream of water with a drop of liquid dish detergent. Start rubbing with the wet sandpaper to clean off any burned-on mess.
For restoration projects, it is recommended to use automotive wet/dry sandpaper in 400, 600, 800, 1000, 1500, and 2000 grit sizes. In cases of heavy oxidation, 320 grit may be used but exercise caution as it is more aggressive than the finer grades. For the first few grades of sandpaper, you can dry sand and rinse and dry the pan between grades. For the finer grades, switch to wet sanding under a trickle of running water to prevent the sandpaper from gumming up.

Dishwasher with detergent
It is not recommended to put aluminium pans in the dishwasher as it can ruin the finish of the pans. The combination of the caustic dishwasher detergent, the high heat, and the minerals in the water can trigger a reaction that darkens the metal. This reaction can also cause white powdery spots to form on the pan. This effect is amplified with every cycle through the dishwasher.
If you want to age your aluminium pans with a dishwasher, you can try the following method:
- Wrap the aluminium pans in foil.
- Place the pans on the dishwasher rack.
- Add powdered dish detergent and trisodium phosphate to the dispenser.
- Run the dishwasher on a cycle with the dry setting turned on.
- Once the cycle is complete, carefully remove the pans from the dishwasher.
- Unwrap the foil from the pans.
- Repeat the process as needed to increase the aged look.
Alternatively, you can try the following method without using a dishwasher:
- Roughen the surface of the aluminium pans with sandpaper.
- Spray the pans with bleach.
- Wear protective gloves and a mask, and perform this step in a well-ventilated area.
- Place the pans in direct sunlight for a few hours.
- Rinse the bleach off the pans with water.
- Soak the pans in a container of water for a few minutes to remove any remaining bleach.
- Dry the pans with a clean cloth.

Soak in oxygen-based cleaner
Soaking in an oxygen-based cleaner is one of several methods to age aluminum and give it a distressed look. This process involves submerging the aluminum object in a solution of oxygen-based cleaner and water, which causes oxidation and a colour change in the metal.
To begin, choose an oxygen-based cleaner such as Oxi-Clean, Clorox OxyAction, All Oxi-Active, or Shout Oxy Powder. You can also make your own cleaner by mixing equal parts sodium percarbonate (dry, powdered hydrogen peroxide) and sodium carbonate (washing soda or soda ash). Next, find a container that is large enough to completely submerge your aluminum object. Place a few tablespoons of the oxygen-based cleaner in the container and add water. Swirl the mixture to ensure the powder is dissolved and add more cleaner if needed—you should see oxygen bubbles forming in the water.
Now, place your aluminum object in the container and ensure it is fully submerged. If your container is large, place a weight on top of the aluminum to keep it from floating. Allow the aluminum to soak for at least 24 hours. A deeper colour change can be achieved by soaking for up to two days.
Once you are happy with the colour, remove the aluminum from the solution. Use a razor blade or plastic card to remove any crusts of oxygen-based cleaner that may have formed on the surface. Finally, rinse the aluminum with a mixture of distilled white vinegar and water. For every cup of water, mix in one tablespoon of vinegar.
