You've probably seen it online: crumpled aluminum foil tossed into a dishwasher cycle with claims it can make your silverware sparkle like new. But does this viral hack actually work—or is it just internet hype? In this article, we dive into the science behind using aluminum foil in dishwasher, explore how effective it really is on different types of dishes, and explain the pros, cons, and safety tips you should know before trying it yourself.
What Is the Aluminum Foil Dishwasher Hack?
The Viral Origin on TikTok
The aluminum foil dishwasher hack gained widespread attention after Australian influencer Carolina McCauley shared a video on TikTok demonstrating the technique. In her video, she crumples a sheet of aluminum foil into a ball, places it in the dishwasher's utensil basket alongside tarnished silverware, and runs a normal cycle. The result: sparkling, like-new utensils.
Why It’s Gaining Attention
This hack has captivated many due to its simplicity, low cost, and the visibly impressive results it delivers. Users are drawn to the idea of reviving dull silverware without the need for specialized cleaners or manual polishing. The method's virality on social media platforms has further fueled its popularity.
How Does It Work?
The Science Behind the Hack
The effectiveness of this hack lies in a chemical reaction between the aluminum foil and the dishwasher detergent, particularly those containing baking soda. When combined with hot water, this reaction facilitates an ion exchange process that helps remove tarnish (silver sulfide) from silverware, restoring its shine.
Role of Hot Water and Steam
Hot water and steam play a crucial role by accelerating the chemical reaction. The heat enhances the interaction between the aluminum foil and the detergent, making the tarnish removal process more efficient during the dishwasher cycle.
Step-by-Step: How to Use Aluminum Foil in Dishwasher

-
A small sheet of aluminum foil
-
Your usual dishwasher detergent
Preparation
Crumple the aluminum foil into a loose ball, approximately the size of a ping-pong ball.
Placement
Place the foil ball in the cutlery basket or utensil tray of your dishwasher. Ensure it is not wrapped around any utensils; the foil should be free-floating to allow proper interaction during the wash cycle.

Does It Really Work? Honest Reviews and Results
Effectiveness on Silverware
Many users report that placing a small ball of aluminum foil in the dishwasher helps remove light tarnish and dullness from silverware. It’s not a deep-cleaning method, but it does give forks, spoons, and knives a noticeably shinier appearance after just one wash. The foil reacts with detergent and helps reduce oxidized residue, especially on stainless steel and silver-plated cutlery.
Does It Clean Glasses or Dishes?
When it comes to cloudy glasses or plates, the aluminum foil trick doesn't show the same results. Since the hack relies on a mild chemical reaction that targets tarnish (typically on metal), it has little to no effect on hard water stains or foggy glassware.
How It Compares to Other Cleaning Methods
Foil vs. Vinegar and Baking Soda
When comparing aluminum foil to natural methods like vinegar and baking soda, it’s clear that each has its strengths. Vinegar and baking soda are more effective for removing general buildup, mineral deposits, and cloudy film on glasses and plates.
Meanwhile, aluminum foil is more targeted, primarily benefiting metal utensils by improving shine.
Foil: Best for silverware shine.
Vinegar & Baking Soda: Better for deep-cleaning and tackling hard water stains.
Pros and Cons of Each
Aluminum Foil

Safe when used properly.
-
Limited effect—only works on metal utensils.
Vinegar & Baking Soda
-
Versatile: Can clean a wide range of dishes and surfaces.
-
Great for descaling and removing grime.
-
May take more time and prep work.

Can’t restore tarnish on silverware as effectively.
FAQs About Aluminum Foil in the Dishwasher
Is it dishwasher safe to use aluminum foil?
Yes, using a small crumpled ball of aluminum foil in the dishwasher is generally safe. It should be placed in the cutlery basket or top rack, away from direct contact with heating elements.
Will it damage my utensils or dishwasher?
Not if used correctly. It’s best used with stainless steel or silver-plated utensils. Avoid using foil with non-stick, aluminum, or gold-plated items, as it may cause discoloration or minor surface reactions.
How often should I do this hack?
Most people find it useful to repeat the process once every few weeks, especially when silverware starts to look dull or spotted.
Can I use this with aluminum utensils?
No. Aluminum utensils can oxidize, turning dark or developing stains if exposed to foil or certain detergents in the dishwasher.
Conclusion
Putting aluminum foil in the dishwasher may sound odd, but it’s a surprisingly effective way to restore shine to dull silverware—especially when used properly and sparingly. While it won't help with cloudy glasses or deep cleaning dishes, it’s a quick, low-cost method to bring life back to your cutlery. As long as you avoid using it with aluminum utensils and place it correctly in the dishwasher, there’s little risk. If you’re looking for a simple kitchen hack to brighten your next load, this one’s worth a try.
