Keeping your aluminum utensils looking clean and shiny doesn’t have to be difficult! By following these simple steps for cleaning discolored aluminum, you can ensure that your kitchenware remains beautiful for years to come

So What Causes Aluminum Discoloration in the First Place? 

Aluminum is an extremely resilient material, but in a humid atmosphere or in contact with seawater or freshwater, it tarnishes to a degree that depends on the medium. 

This phenomenon is known as “blackening” and is not a type of corrosion but merely an alteration of the visual properties of the film of natural oxide.

Fortunately, Cleaning Discolored Aluminum Is An Easy Task!

To do this, boil a solution of two to three tablespoons of cream of tartar, lemon juice, or vinegar per quart of water in the utensil for 5 to 10 minutes. 

Next, lightly scour with a soap-filled scouring pad. If necessary, repeat this process until all discoloration has been removed and your utensils shine like new again!

Another great way you can help prevent aluminum discoloration in the future is by using protective food-grade oil such as mineral oil or vegetable oil when cleaning these items, as they will help protect them from corrosion and keep them looking shiny and new. 

It’s also important to remember not to use abrasive cleaning agents like steel wool or harsh chemicals like bleach which can damage the surface of your aluminum items.

Remember that prevention is key – always use protective food-grade oils when cleaning these items and never use abrasive cleaning agents or harsh chemicals that could damage the surface over time. 

How To Keep Your Aluminum Shiny and New?

How Do You Clean Discolored Aluminum

Aluminum is an incredibly versatile and resilient metal, making it a popular choice for many items used in everyday life. From cookware to furniture, aluminum can be found in many places. But with constant exposure to heat, moisture, and wear and tear, aluminum can easily become dull or cloudy. 

Thankfully, there are easy ways to keep your aluminum shiny and new! Let’s consider how you can bring the shine back to your favorite aluminum items.

Polishing Your Aluminum

If your aluminum has become dull or cloudy over time, don’t worry- it happens! To get the shine back in your aluminum items, you’ll need some mild dishwashing detergent and an abrasive sponge. 

First, squeeze one or two drops of mild dishwashing detergent into a cup of water. Then apply the soapy water to an abrasive sponge and scrub the aluminum vigorously. Make sure not to apply too much pressure as this could damage the aluminum surface. 

Anodised aluminum requires a gentler touch- if you have anodised aluminum products, use a softer cleaning solution, as harsher ones can react with the metal.

Protecting Your Aluminum

To keep your aluminum looking nice after it’s all polished up again, you can use a sealant or wax on its surface. Sealants act as a protective barrier that keeps dirt and dust away from your item while preventing discoloration from UV rays or other elements like water or sunlight exposure. 

Waxes will also do the trick- they protect against scratches while providing lasting shine for your item! Additionally, anodising is another great way to protect your item from scratches or fading colours. 

Anodizing involves passing electrical currents through the piece of metal, which helps form a protective layer over it- perfect for keeping those shiny metals gleaming for years!

It’s easier than ever to keep your favorite pieces of aluminum looking their best! So go ahead – get out there and make those metals sparkle!


Cleaning discolored aluminum is no easy feat, but expert advice and a few materials can make it feel like a breeze. The key to avoiding the chore of deep cleaning discolored metal lies in preventing rust from appearing in the first place. 

Regularly inspecting and polishing metal outdoors, particularly in high-humidity environments, is an excellent way to ensure metal stays clean, sleek, and polished for longer periods of time. 

Moreover, it’s important to store items made out of aluminum away from wet surfaces to prevent build-up or contamination over time. 

Careful cleaning practices – such as using mild soaps or abrasive cleaners without allowing chemicals to sit on the metal – plus a watchful eye can have aluminum looking better than ever before!
