Can Metal Go In The Dishwasher

In this era of modern convenience, the dishwasher has become an indispensable appliance in many households. It saves time and effort, making the dreaded task of dishwashing a breeze. However, as we load our trusty dishwashers with dirty dishes, a common question arises: Can metal go in the dishwasher? In this comprehensive guide, we will explore this query in detail, providing you with valuable insights and recommendations.

The Dishwasher Dilemma

Before we delve into the intricacies of placing metal items in the dishwasher, let’s first understand the dishwasher’s basic operation. Dishwashers employ a combination of hot water, detergent, and powerful jets to clean and sanitize your dishes. The internal environment can be harsh, with high water temperatures and strong water pressure. It’s this environment that raises concerns about the compatibility of metal items.

Stainless Steel: A Stalwart in the Dishwasher

When it comes to metal, stainless steel is your best bet for dishwasher compatibility. This resilient alloy is widely used in kitchen appliances and cookware for good reason. Stainless steel exhibits remarkable resistance to corrosion, making it suitable for exposure to hot water and detergents. Most stainless steel cookware, utensils, and flatware can safely endure the dishwasher’s cleaning process without adverse effects.

Stainless Steel Utensils:

Stainless steel utensils, such as forks, knives, and spoons, are dishwasher-safe. However, some precautions are advisable to maintain their longevity:

  • Separation: Ensure that stainless steel utensils do not come into direct contact with other metals in the dishwasher. This prevents the possibility of galvanic corrosion.
  • Avoid Harsh Detergents: Opt for mild dishwasher detergents to protect the finish of your stainless steel utensils.
  • Load Carefully: Arrange your utensils in a way that allows water to flow freely around them, ensuring thorough cleaning.

Other Metal Items: Proceed with Caution

While stainless steel is dishwasher-friendly, not all metal items share the same resilience. Here’s a breakdown of other common metal items you may encounter in your kitchen and whether they can safely go in the dishwasher.

Aluminum Cookware:

Aluminum pots and pans can be washed in the dishwasher, but prolonged exposure may cause discoloration. Handwashing is often recommended for extended durability.

Cast Iron Cookware:

Cast iron cookware should never be placed in the dishwasher. The high heat and moisture can strip away the seasoning and promote rust formation. Handwashing with minimal soap and proper seasoning is the preferred method for cleaning and maintaining cast iron.

Copper Cookware:

Copper pots and pans are a beautiful addition to any kitchen, but they are not dishwasher-friendly. The dishwasher’s harsh environment can tarnish the copper’s luster. Handwashing with a gentle cleanser is the way to go for copper cookware.

Non-Stick Cookware:

Most non-stick pans have a coating that can deteriorate in the dishwasher. Handwashing with a soft sponge and mild detergent is recommended to extend their lifespan.


Sterling silver and silver-plated flatware should not be placed in the dishwasher. The high water temperatures and harsh detergents can tarnish the silver. Handwashing with a silver-specific cleanser is the best way to preserve their shine.

Final Verdict

In conclusion, the question of whether metal can go in the dishwasher depends on the type of metal. Stainless steel utensils are generally safe for dishwasher use, provided you follow a few precautions. However, for other metal items like aluminum, cast iron, copper, non-stick cookware, and silverware, it is advisable to steer clear of the dishwasher and opt for gentle handwashing methods to ensure their longevity and performance.

Remember that proper care and maintenance of your kitchenware not only extend their lifespan but also enhance your overall cooking and dining experience. So, the next time you load your dishwasher, take a moment to consider the materials you’re putting in and treat them with the care they deserve.
