Air fryer parts (baskets, trays, racks) labeled as safe to wash in a dishwasher without warping or breaking. While convenient, dishwasher detergent is abrasive and significantly accelerates the degradation of nonstick coatings. 'Dishwasher-safe' means the part survives the dishwasher, not that the coating is unaffected.

Reality Check
What brands claim
What it actually means
When you are shopping for an air fryer with a family to feed and a kitchen to clean afterward, "dishwasher-safe" ranks high on the feature wish list. And manufacturers know it - you will see the term prominently on nearly every air fryer sold today. But there is a gap between what dishwasher-safe means technically and what most parents assume it means.
We looked into what actually happens to air fryer components in the dishwasher, and the answer matters for both convenience and the longevity of your investment.
When a manufacturer labels an air fryer basket or tray as dishwasher-safe, they are stating that the part will not:
That is the full extent of the claim. Dishwasher-safe does not mean:
This distinction is not a technicality. It is the difference between a nonstick basket that lasts 3-5 years with hand-washing and one that may show significant coating degradation in 1-2 years with regular dishwasher use.
Dishwasher detergent is fundamentally different from hand dish soap. It is designed to clean aggressively at high temperatures without manual scrubbing. This requires much stronger chemical formulations:
Dishwasher detergent is highly alkaline (high pH), typically pH 10-12. This alkalinity is what dissolves baked-on food and grease without scrubbing. But alkaline chemicals also attack nonstick coatings, gradually breaking down the polymer bonds that create the nonstick surface.
PTFE (Teflon) coatings are relatively resistant to alkaline degradation but are not immune. Over many cycles, the coating becomes thinner and less effective. The nonstick surface gradually roughens at a microscopic level, and food starts sticking in patches.
Ceramic nonstick coatings (sol-gel silica) are more vulnerable to alkaline degradation than PTFE. The silica-based coating can be stripped more quickly by high-pH detergents. Families who choose ceramic nonstick for material safety reasons should be especially careful about dishwasher use, as degrading the coating faster means replacing the basket sooner.
Many dishwasher detergents contain mild abrasives or bleaching agents that help remove stuck-on food. These can create micro-scratches on nonstick surfaces that are invisible to the naked eye but progressively reduce nonstick performance.
The heated drying cycle in a dishwasher subjects components to sustained heat that can cause thermal stress on coatings, particularly at the edges where the coating bonds to the base metal. Over time, this can lead to coating flaking or peeling starting at the edges.
High-pressure water jets in the dishwasher can accelerate coating wear, particularly at edges and corners where the coating is already thinnest.
Stainless steel baskets, racks, and trays are genuinely dishwasher-safe with no coating concerns. There is no nonstick layer to degrade. Stainless steel handles the alkaline detergent, high temperatures, and water pressure without any negative effects. Some discoloration may occur but does not affect performance or safety.
Verdict: Use the dishwasher freely. This is the one material where dishwasher-safe truly means worry-free.
PTFE coatings tolerate dishwasher cleaning better than ceramic coatings but still degrade faster than with hand-washing. The alkaline detergent gradually thins the coating over many cycles. You may notice food starting to stick after 50-100 dishwasher cycles (compared to several hundred hand-wash cycles for a quality PTFE coating).
Verdict: Occasional dishwasher use is fine. But if you want the coating to last, hand-washing is significantly better. If you dishwasher-clean the parts regularly, expect to replace the basket sooner.
Ceramic nonstick coatings are the most vulnerable to dishwasher damage. The sol-gel silica coating degrades faster in alkaline environments than PTFE. Families who chose ceramic nonstick specifically to avoid PFAS may find themselves replacing baskets more frequently if they rely on the dishwasher.
Verdict: Hand-wash whenever possible. If you must use the dishwasher, choose a gentle cycle with a mild detergent. Expect reduced coating lifespan.
Uncoated aluminum can discolor in the dishwasher due to the alkaline detergent reacting with the aluminum oxide surface layer. This discoloration is cosmetic and not a safety concern, but it is permanent. Some aluminum parts may develop a dull, chalky appearance after repeated dishwasher cycles.
Verdict: Safe but may discolor. Hand-washing preserves appearance.
We understand the tension here. You just cooked dinner for the family, the kids need baths, and the last thing you want to do is stand at the sink hand-washing air fryer parts. The dishwasher exists for exactly this reason.
Here is our practical guidance:
If easy cleanup is your top priority and you are willing to replace the basket when the coating wears out - use the dishwasher. A nonstick basket that lasts 1-2 years instead of 3-5 years is still providing value if it saves you time every day.
If maximizing coating lifespan matters (because you have an expensive air fryer or want to minimize waste) - hand-wash. It takes 3-5 minutes with warm soapy water and a soft sponge.
The compromise approach: Hand-wash most of the time and use the dishwasher when you truly need the convenience. Even reducing dishwasher use to once or twice a week instead of daily extends coating life significantly.
If you chose stainless steel - use the dishwasher every time. There is no coating to worry about.
When you do hand-wash, a few practices help both cleaning effectiveness and coating preservation:
Dishwasher use accelerates nonstick coating degradation, potentially leading to earlier exposure of the base metal (usually aluminum) to food. Degraded PTFE coatings may release more microparticles during cooking. Ceramic nonstick coatings that thin prematurely lose their intended barrier function. Stainless steel components have no health concerns from dishwasher use.
There is no FDA or CPSC regulation specifically defining "dishwasher-safe" for air fryer components. The claim is a manufacturer designation based on internal testing. The FDA regulates food contact materials including nonstick coatings, but does not address how cleaning methods affect those materials over time. NSF/ANSI 51 covers food equipment materials but primarily applies to commercial equipment.
Dishwasher use is physically safe for labeled parts. The concern is accelerated coating degradation leading to earlier base metal exposure. Once the nonstick coating is significantly worn, the underlying metal (typically aluminum) contacts food directly, which may increase aluminum leaching into acidic foods. Replace coated parts when the coating shows visible wear rather than continuing to use them with degraded coatings.

Check the product manual for specific dishwasher instructions. After several dishwasher cycles, run your finger across the nonstick surface - if it feels rougher than when new, the coating is showing wear. Compare the nonstick performance by cooking the same food with minimal oil - increased sticking indicates coating degradation.

Dishwasher cleaning uses high-pH alkaline detergent, high-temperature water (130-160F), high-pressure water jets, and a heated drying cycle to clean without manual scrubbing. This combination is effective at removing baked-on grease and food but is chemically and mechanically more aggressive than hand-washing with mild dish soap. The alkaline chemistry gradually attacks the polymer bonds in nonstick coatings, and the abrasive components create micro-scratches that accumulate over time.

Every product scored on safety, efficacy & value - so you know which air fryer to trust around dishwasher-safe components.
It will not ruin it in the sense of breaking or warping it (if labeled dishwasher-safe). But dishwasher detergent will degrade the nonstick coating faster than hand-washing. Over time, you will notice food starting to stick in areas where the coating has thinned. This happens gradually - not from one or two cycles, but from regular dishwasher use over months.
This varies by coating quality and dishwasher frequency, but as a general guide: regular dishwasher use (3-5 times per week) may reduce coating effective life to 1-2 years, compared to 3-5 years with hand-washing. Higher-quality coatings from premium brands tend to withstand dishwasher cleaning longer.
For coating longevity, yes. Hand-washing with warm water, mild dish soap, and a soft sponge is significantly gentler on nonstick coatings than dishwasher detergent. If you soak the basket in soapy water right after cooking, cleaning takes 3-5 minutes. The exception is stainless steel - it performs identically whether hand-washed or machine-washed.
[Ceramic nonstick](/learn/technology/ceramic-nonstick-technology) coatings are the most vulnerable to alkaline dishwasher detergent. If you have been dishwashing the basket regularly, that has likely accelerated the coating degradation. For ceramic coated parts, hand-washing is strongly recommended to preserve coating performance.
If the manufacturer says top rack only, follow that guidance. The bottom rack is closer to the heating element and water jets are more direct, which increases both heat exposure and mechanical stress on the coating. If the manufacturer says fully dishwasher-safe without restriction, either rack is fine structurally.
Yes. Stainless steel has no nonstick coating to degrade. It handles alkaline detergent, high temperatures, and water pressure without any performance or safety impact. Some cosmetic discoloration may occur but does not affect cooking or safety. Stainless steel is the one material where dishwasher-safe means genuinely worry-free.
A sol-gel silica-based nonstick coating applied to air fryer baskets and cookware as an alternative to traditional PTFE (Teflon). Generally PFAS-free. Common trade names include Thermolon (GreenPan) and Ilag (Swiss). Less durable than PTFE, typically lasting 1 to 3 years, but safe at higher temperatures and free from fluoropolymer concerns.
Traditional polytetrafluoroethylene (Teflon-type) nonstick coating used on air fryer baskets and cookware. The most durable nonstick option with a 3 to 5 year lifespan. Safe below 500F but can release toxic fumes above that temperature. PTFE is itself a PFAS compound, and manufacturing may involve PFOA or GenX processing aids.
Regardless of how you clean your air fryer parts, nonstick coatings eventually wear out. Replace coated baskets and trays when:
Coating degradation is not inherently dangerous in most cases - ingested coating fragments pass through the digestive system. But a degraded coating means the base metal (typically aluminum) is now exposed to food acids, oils, and heat, which can cause aluminum leaching. Replacing worn coated parts maintains both nonstick performance and material safety.
