When I first started baking at home, I thought I had found the perfect shortcut: instead of scrubbing trays by hand, why not just toss them in the dishwasher? After all, that’s what the machine is for, right? The first time I did it, I pulled out my tray and it looked… different. The shine was gone, a few spots looked cloudy, and the surface felt rougher. That’s when I realised the answer to whether bakery trays can go in the dishwasher isn’t a simple yes or no.
Let’s dig into this, because it’s a question almost every baker has asked at some point.
The Short Answer
Yes, baking trays can go in the dishwasher in Australian kitchens, but should they? Not always. It depends on the material, the coating, and how much you care about the tray's long-term condition.
Some trays survive dishwashers just fine. Others end up discoloured, warped, or with their non-stick coating peeling. That’s why it’s worth breaking things down by tray type.
Aluminium Baking Trays
Most professional sheet pans are made from aluminium. They’re lightweight, conduct heat well, and they’re affordable. The downside? Aluminium and dishwashers don’t get along.
The harsh detergent and high-temperature water in dishwashers can cause aluminium trays to oxidise. You’ll notice a dull grey film or even chalky residue after a few washes. It doesn’t necessarily make the tray unsafe, but it ruins the look and can affect how food cooks.
I learned this lesson with my first half-sheet tray. After two dishwasher cycles, it looked 20 years old. From then on, I’ve always washed aluminium trays by hand with warm water and mild soap.
Stainless Steel Baking Trays
Stainless steel is tougher. These trays can usually handle dishwashers better than aluminium. They don’t oxidise, and they’re more resistant to harsh detergents.
That said, stainless trays can still discolour or develop “rainbow stains” after repeated dishwasher cycles. It doesn’t ruin them, but if you want them to look shiny and new, you might prefer to hand-wash.
Non-Stick Coated Trays
Here’s where things get tricky. Non-stick trays are convenient because food slides right off. But the coatings are delicate. Dishwashers expose them to strong detergents and very hot water, both of which shorten the life of the coating.
Manufacturers often say non-stick trays are “dishwasher safe,” but most experienced bakers will tell you to wash them by hand. Once that coating starts peeling, the tray is basically useless.
Enamel and Ceramic-Coated bakery Trays
These trays usually hold up better in dishwashers. The enamel or ceramic coating protects the metal underneath, so it resists staining and rust. Still, harsh detergents can sometimes cause tiny cracks in the surface over time.
I’ve had a white enamel roasting tray for years that I occasionally run through the dishwasher. It’s still intact, but it doesn’t look as bright as it did when it was new.
Glass Baking Dishes
Technically, not trays, but many people use glass for baking. Glass is completely dishwasher safe. It doesn’t rust, warp, or absorb detergent. The only risk is that handling heavy glass can bump around in the dishwasher and chip if it hits something.
The Risks of Using a Dishwasher
Even if a baking tray is labelled dishwasher safe, here are the risks you run:
-
Discolouration: Aluminium goes dull, stainless steel gets rainbow stains.
-
Warping: Thin trays can bend under the heat and water pressure.
-
Peeling coatings: Non-stick surfaces degrade faster.
-
Residue buildup: Sometimes detergent leaves a film that’s hard to scrub off.
And honestly, baking trays usually don’t need heavy cleaning. Most of the time, a soak in warm water and a scrub with a sponge does the job.
Tips If You Do Use the Dishwasher
If you absolutely want to use the dishwasher, here are a few ways to minimise damage:
-
Check the label. If the manufacturer says “hand wash only,” don’t risk it.
-
Use the top rack. It keeps trays farther from the heating element.
-
Skip heated dry. Let the tray air dry to avoid warping.
-
Don’t crowd. Make sure the tray isn’t jammed in tightly against other items.
-
Limit frequency. Even if dishwasher safe, don’t make it a daily habit.
My Routine Now
After years of trial and error, here’s what I do:
-
Aluminium trays? Always by hand. Warm water, a little soap, and if something’s really stuck, a baking soda paste.
-
Stainless trays? Dishwasher occasionally, hand-wash most of the time.
-
Non-stick trays? Always by hand, I want the coating to last.
-
Glass dishes? Straight into the dishwasher, no worries.
It adds a few minutes of work, but my trays last longer and still look good.
Why Good Trays Deserve Good Care
Baking trays aren’t expensive compared to some kitchen tools, but they’re worth looking after. A warped or scratched tray doesn’t just look bad; it affects how evenly food bakes. Cookies spread differently, pastries brown unevenly, and breads can stick.
That’s why I always tell new bakers: treat your trays well from the start. Don’t put them through the dishwasher every time, don’t use metal scouring pads, and don’t crank up the oven heat beyond what the tray can handle. A little care means years of reliable use.
Why I Recommend HomeMyGarden for Baking Trays
If you’re shopping for trays and wondering which ones actually last, HomeMyGarden is a good place to start. Their trays are practical, durable, and they come in the sizes bakers actually use , from half sheets for home ovens to full sheets for bigger batches.
What I like most is the quality balance. They’re sturdy enough for daily baking but still light enough to handle easily. And because the materials are well chosen, you don’t have to second-guess whether they’ll survive a wash.
Final Thoughts
So, can bakery trays go in the dishwasher? Yes, but with caution. Stainless steel and enamel trays usually survive fine, glass dishes are safe, but aluminium and non-stick trays are better off washed by hand.
The real question is: do you want your trays to last? If the answer is yes, spend the extra couple of minutes hand-washing. It’ll keep them looking good, cooking evenly, and serving you well for years.
And if you’re looking to upgrade, check out HomeMyGarden. Their baking trays give you the right balance of size, durability, and ease of use , the kind of trays worth taking care of properly.
At the end of the day, the dishwasher might save you a little time, but good trays are an investment. Treat them right, and they’ll reward you with better bakes every single time.
