Check Out What Items Are Not Dishwasher Safe

Why aren’t all dishes and cutlery safe to clean in the dishwasher? In some cases, the material itself doesn’t respond well to the elements inside a running dishwasher. Other items can be dulled or worn down by the cleaning process.

Keep These Out of the Dishwasher

We’ll start with the obvious; NEVER put any gadgets or electronic devices in the dishwasher! That means you, hand blender. Along with electronics though, keep these common items out of the dishwasher:

what can't go in the dishwasher


  1. Cast Iron Pans – Cast iron pans are not dishwasher safe and can rust if you wash them in the dishwasher.
  2. Wooden Cutting Boards – Wooden cutting boards can warp in the dishwasher and should be washed by hand with soap and water.
  3. Wooden Utensils – Wooden utensils can also warp in the dishwasher, often making them unusable.
  4. Aluminum Pans – Aluminum pans can discolor in the dishwasher. This happens because the dishwasher’s high temperatures cause a chemical reaction with the aluminum.
  5. Non-Stick Pans – Non-stick pans can also be damaged in the dishwasher. The high temperatures can cause the non-stick coating to break down and flake off.
  6. Knives – Knives are high on the list of what items are not dishwasher safe since they can quickly become dull when they bang around in a dishwasher.
  7. Crystal Glasses – The heat and chemicals can cause them to break, which is not only frustrating but also expensive to replace.
  8. Pottery – Pottery can break in the dishwasher if it is not rated as dishwasher safe.

If you’re not sure whether you’re working with dishwasher-safe cookware, it’s always best to err on the side of caution and wash it by hand. Be sure to check for a not dishwasher safe symbol as well as washing instructions on your dishware so you can know what items are and are not dishwasher safe.
