The Science Behind Aluminum Reactivity
Aluminum is a reactive metal, which means it can undergo oxidation when exposed to certain substances or environments. This is a crucial factor to consider when washing aluminum items in a dishwasher:
Oxidation Process: When aluminum is exposed to oxygen, a layer of aluminum oxide forms on its surface. This layer protects the underlying metal from further corrosion.
Dishwashing Environment: Dishwashers often use high temperatures, detergents, and sometimes acidic dishwashing solutions that can accelerate the oxidation process on aluminum.
Common Types of Aluminum Kitchen Items
Before discussing the effects of dishwashing on aluminum, it’s important to consider what type of aluminum you might have in your kitchen:
Aluminum Foil: Frequently used for wrapping food or lining dishes, its thin structure makes it particularly vulnerable to damage and discoloration.
Aluminum Bakeware: Pans and trays made from thicker aluminum can withstand more wear and tear, but they are not immune to the effects of dishwasher detergents and high heat.
Anodized Aluminum: This type involves an electrochemical process that enhances durability and resistance to corrosion and discoloration. It typically fares better in dishwashers than standard aluminum.
The Impact of Dishwashing on Aluminum Items
So what actually happens when you place aluminum items in the dishwasher? The outcome can vary significantly based on the type of aluminum, the dishwasher settings, and the detergents used.
Potential Consequences of Dishwashing Aluminum
Discoloration: One of the most immediate effects of dishwashing aluminum items, especially uncoated aluminum, is discoloration. This can manifest as dullness or a darkened surface, obscuring the shiny finish typically associated with aluminum cookware.
Pitting and Corrosion: Dishwashing detergents can be abrasive, leading to surface pitting or other forms of corrosion. This is particularly true for bare aluminum, which lacks the protective layer that anodized surfaces possess.
Warping: High dishwasher temperatures can cause thin aluminum items to warp. This is more common in lightweight trays and foil, which may not hold their shape under heat.
Blemishes: Certain detergents may react chemically with aluminum, leading to unsightly blemishes or stains on the surface.
Dishwasher Settings Matter
The impact of the dishwasher on aluminum can also heavily depend on its settings:
High-Temperature Wash: Using a high-temperature wash can exacerbate the adverse effects on aluminum. Avoiding high heat is essential if you must wash aluminum items.
Drying Cycle: The drying cycle has the potential to increase the risk of warping or discoloration. Opting for air-drying instead of heated drying can mitigate some of these risks.
Best Practices for Washing Aluminum Cookware
To preserve your aluminum items and extend their life, consider these best practices:
Handwashing as an Alternative
Handwashing is often the safest way to clean aluminum cookware:
- Use a gentle dish soap and warm water.
- Employ a soft sponge or cloth to avoid scratching the surface.
Using the Right Detergent
If you must use a dishwasher, select a mild detergent that specifically states it’s safe for aluminum. Avoid detergents with strong acidic properties or bleach, which can heighten the potential for damage.
Storage Tips for Aluminum Cookware
Proper storage can also help you maintain aluminum cookware:
- Avoid Scratching: Stack aluminum pans with protective layers such as cloth or paper towels to avoid scratching.
- Dry Thoroughly: Ensure that aluminum items are completely dry before storing to prevent moisture-related corrosion.
Rehabilitation: What to Do If Aluminum Has Discolored or Pitted
If you’ve already washed aluminum in the dishwasher and found discoloration or pitting, don’t worry! There are techniques to restore your aluminum’s appearance:
Polishing Aluminum
Using commercial aluminum polish or a DIY solution can help restore the shine:
- Mix equal parts of vinegar and baking soda to create a paste. Apply this to the affected areas with a soft cloth and rub gently.
- Rinse thoroughly and dry immediately.
