Can You Put Baking Trays in the Dishwasher?

Yes, you can put most baking trays in the dishwasher. However, it’s essential to consider the type of material and any manufacturer’s instructions before doing so.

Stainless steel, aluminum, and enameled cast iron trays can generally be dishwasher-safe, but it is always recommended to follow the manufacturer’s guidelines.

Trays made of non-stick materials, such as Teflon, can lose their non-stick qualities if frequently washed in a dishwasher. It’s best to hand-wash these baking trays to ensure their longevity.

Additionally, uncoated aluminum trays can get discolored in the dishwasher due to the alkaline detergents. While this does not affect their performance, it may not be aesthetically pleasing.

In summary, it is possible to put baking trays in the dishwasher, but the material and manufacturer’s instructions should be taken into account to prevent potential damage or reduced efficacy.

If in doubt, handwashing your baking trays is always a safe alternative.

How do I know if my dishes are dishwasher safe?

Identifying if dishes are dishwasher safe can be a little complicated, as it largely depends on the material from which they are made. However, there are a few things that can help you determine this:

  1. Check for a dishwasher-safe symbol: Many products nowadays have symbols to indicate if they’re dishwasher safe. It’s commonly depicted as dishes in a box filled with water droplets or waves.
  2. Manufacturer’s instructions or labels: Some items are clearly labeled or come with instructions that specify if they’re safe to go in the dishwasher. Always check for this information.
  3. Manufacturer’s instructions or labels: Some items are clearly labeled or come with instructions that specify if they’re safe to go in the dishwasher. Always check for this information.
  4. Material of dishes:
    • Ceramic/Stoneware/Porcelain: These are mostly dishwasher safe unless they are hand-painted, antique, or have a gold/silver rim, which could be damaged in the dishwasher.
    • Glass: Most glassware is dishwasher safe, as long as it’s not hand-painted, antique, or contains lead.
    • Plastic: Check for a “dishwasher safe” label or symbol. Some plastics can warp and crack in the extreme heat of a dishwasher. Beware of BPA, a harmful chemical that can leak out of some plastics when heated.
    • Metals: Stainless steel and aluminum utensils are generally safe, but sharp knives can get dull in the dishwasher. Silver, copper, non-stick coated items, and iron pans should always be hand-washed. Non-stick coatings can peel off over time, and copper, iron, and silver can tarnish.
  5. Consider age and condition: Older dishes or those in poor condition can become damaged in the dishwasher. Hand-paintings, prints, or decorations can fade over time, and cracked dishes might break further in the dishwasher.

When in doubt, it’s always a safer bet to hand-wash your dishes to maintain their quality and appearance.

What happens if you put non dishwasher safe?

Putting non-dishwasher safe items in the dishwasher can lead to a variety of unfavorable outcomes.

Firstly, kitchenware such as wood or wooden-handled items subjected to the high temperature and moisture within a dishwasher can warp, splinter, and crack.

Even minor cracks or splintering can harbor harmful germs and bacteria that could contaminate your food. Delicate items or those with hand-painted ceramics can have their designs faded or completely washed off.

Secondly, if your dishes have a non-stick coating, the intense conditions inside a dishwasher could cause the coating to deteriorate. This not only reduces the item’s non-stick properties but could also potentially introduce harmful substances into your food the next time you use the utensil.

Furthermore, items made from certain types of plastic may not be dishwasher safe. When the heat from a dishwasher is applied, harmful chemicals such as phthalates and BPA might leach from the plastic.

Besides potential damage to your items, there’s also a risk of causing harm to the dishwasher itself. Certain items, especially those with loose parts or made from materials prone to melting or warping, could clog or damage the dishwasher’s inner mechanisms.

Making a habit of checking for manufacturer’s instructions or labels indicating an item’s compatibility with dishwashers is a key takeaway. When in doubt, opt for hand-washing to maintain the integrity of your kitchen items and ensure your dishwasher’s smooth operation.

Does glass and fork symbol mean dishwasher safe?

Yes, the symbol of a glass and fork generally indicates that a product is safe for food use. However, it is crucial to note that this symbol does not necessarily mean that the item is dishwasher safe.

Dishwasher safe symbols can vary, often depicted as dishes in a box filled with water droplets or a plate and glass inside a square.

Nonstick or coated baking sheets can lose their nonstick properties with dishwasher use, thus hand washing is often recommended. Check the manufacturer’s instructions if unsure.


Whether you can put baking trays in the dishwasher largely depends on their material. Stainless steel, enameled cast iron, and some aluminum trays are generally dishwasher-safe, however, trays with non-stick surfaces, copper or certain aluminum types are best hand-washed to maintain their non-stick properties and prevent discoloration.

Plastic or wood-based items should always be washed by hand. Always check the manufacturer’s instructions and look for dishwasher-safe labels if you’re unsure.

Ultimately, proper care and handling of your baking trays not only extends their lifespan, but also maintains their cooking performance and your food’s taste. When in doubt, it’s always a safe bet to hand-wash your trays.
