Dishwasher Dos and Don’ts: What Shouldn’t Go in a Dishwasher?

Though there are multiple items you can clean in a dishwasher, some should stay far away from the spray arms. What shouldn’t go in a dishwasher? Brass, bronze, or pewter pieces become pitted and discolored from the water pressure and heat. Learn what items are not dishwasher safe to avoid permanently damaging them and your hardworking appliance.

While it’s the ultimate kitchen convenience, sometimes the dishwasher’s heat, water pressure, or detergent can do more harm than good. To avoid breakage, discoloration, or rust, this list of what shouldn’t go in a dishwasher can save you time and heartache.

When it comes to what can’t go in the dishwasher, cast iron tops the list. The detergent can actually strip away the naturally non-stick surface, leaving it at risk of rusting. Always handwash cast iron pans using only warm water and a soft, non-abrasive sponge to preserve its non-stick capabilities.

Cutting boards, utensils, and anything with wooden handles are all items that can’t go in the dishwasher. Not only will the detergent scratch the surface, but a heated drying cycle can cause warping and cracks. Handwash these items with warm water and dish soap, using baking soda to remove tough stains.

Unfortunately, aluminum and copper pots and pans are not dishwasher-safe cookware. While their cooking capabilities will remain intact, a single wash cycle can result in significant dulling and discoloration. To keep their shine and color, hand wash aluminum and copper cookware after each use. What can you put in a dishwasher? While you should still check the manufacturer’s recommendations, most stainless steel pots and pans are dishwasher-safe.

Investing in a quality kitchen knife also means investing your time in handwashing it. Dishwasher detergent can dull the blade, making cutting laborious and unsafe. Meanwhile, hot water and the drying cycle’s heat can loosen the handles. Hand wash your best knives with hot water and soap and dry them immediately to preserve their appearance and function.

What shouldn’t go in a dishwasher? Fine china and crystal can chip if movement and water pressure make them knock against other items. In addition, abrasive detergent, hot water, and heat can cause items to fade or lose their painted finish. Always handwash your china and crystal to preserve their delicate beauty.

While pressure cookers and instant pots are time-saving kitchen tools, they’re strictly hand wash only. Putting these lids in the dishwasher exposes them to food particles and debris that can get trapped in the regulator or safety valves. This can permanently alter their airtight seal, hampering their rapid cooking abilities. Always hand wash pressure cooker and instant pot components in warm, soapy water and dry them thoroughly before storing.

While there is no universal not dishwasher safe symbol, most nonstick pans would have one if there were. After repeated wash cycles, the non-stick coating can break down, causing it to flake off during cooking. To preserve your cookware and avoid ingesting these materials, always hand wash non-stick pans unless the manufacturer specifies that they’re dishwasher safe.

Though knowing what shouldn’t go in a dishwasher can prevent damage and part failures, some malfunctions just can’t be avoided. When you need a dishwasher repair service, call Authorized Appliance for prompt and reliable service!
