Aluminum (Uncoated)
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.
The Busy Family Reality
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.
