What Not to Put in the Dishwasher: Pans, Mugs, and Metals Explained

What metal cannot go in the dishwasher

Dishwashers have revolutionized kitchen cleanup, offering convenience and efficiency for everyday tasks. However, not all kitchen items should be tossed into the dishwasher.

While many common dishes are dishwasher safe, there are specific materials and types of cookware that can get damaged under high heat, detergent, or water pressure.

If you’re unsure whether an item is safe to wash in the dishwasher, read on to find out what to avoid putting in this handy appliance—and how to protect your cookware.

1. What Happens If You Put Non-Dishwasher Safe Pans in the Dishwasher?

If you put a non-dishwasher safe pan, like cast iron or non-stick cookware, in the dishwasher, you risk damaging the surface and reducing the pan’s lifespan.

The high heat and harsh dishwasher detergents can strip away the seasoning on cast iron, causing it to rust.

For non-stick pans, the coating may start to chip, making the pan less effective and potentially unsafe for cooking.

Copper pots and pans are also prone to discoloration and pitting if placed in the dishwasher, so it’s always best to hand wash these items to preserve their quality.

Pro Tip: To make cleaning cast iron easier without damaging it, consider using a cast iron cleaner specifically designed for delicate cookware.

2. What Metals Cannot Go in the Dishwasher?

Certain metals, like aluminum, cast iron, and copper, should not go in the dishwasher.

The detergent and high water pressure can cause aluminum to discolor and lose its shine.

Cast iron, on the other hand, needs the natural oils to stay intact for seasoning, which the dishwasher will strip away.

Copper items are also vulnerable to pitting and tarnishing when exposed to dishwasher detergent and high heat. Always hand wash these metals with gentle soap and a soft cloth.

3. What Shouldn’t You Put in the Dishwasher?

Aside from metal cookware, there are several other items that should not be placed in the dishwasher. These include:

  • Wooden items: Wooden spoons, cutting boards, and utensils can crack, warp, or swell due to the high heat and humidity inside the dishwasher.
  • Crystal and delicate glassware: Fine crystal and hand-painted mugs may lose their clarity or get etched by the detergent.
  • Knives: Dishwashers can dull the edges of sharp knives, and the high heat may even damage the handles.

4. Which Mugs Are Not Dishwasher Safe?

Not all mugs are dishwasher safe. Mugs with metallic rims or intricate designs, such as antique or hand-painted mugs, should always be hand washed to avoid fading or cracking.

Insulated mugs, like travel mugs, are also better washed by hand.

The high temperature and water pressure can damage the seals and insulation, affecting their ability to keep beverages hot or cold.

5. Why Are Some Pans Not Dishwasher Safe?

Certain pans are not dishwasher safe because of the materials they’re made from or the coatings they have.

Non-stick pans, for example, can lose their coating and effectiveness when exposed to high heat and harsh detergents.

Similarly, cast iron pans need to retain their natural oils to prevent rusting, which dishwashers can strip away.

Always follow the manufacturer’s care instructions to ensure your cookware lasts longer and performs better.

Conclusion: Careful What You Clean in Your Dishwasher

Understanding what should and shouldn’t go in the dishwasher is key to keeping your kitchenware in top condition.

By carefully choosing which items to wash by hand, you’ll preserve the quality of your cookware and avoid costly replacements. For cookware that is dishwasher safe, be sure to check labels and use the correct cleaning method for each material.
