An air fryer can accumulate oil, crumbs, and small pieces of food during regular use. If these residues remain inside the appliance, they may begin to smoke or produce unpleasant odors during later cooking cycles.
Grease and food particles can collect in the basket, tray, and other removable components. Over time, this buildup may also make cleaning more difficult and affect the taste or smell of newly prepared food.
To reduce these problems, allow the appliance to cool completely and unplug it before cleaning. Remove the basket and tray according to the manufacturer's instructions, then wash them using a suitable method. A soft sponge or cloth is generally preferable to abrasive tools that may damage nonstick surfaces.
The heating element and interior should be cleaned only as directed by the manufacturer. Avoid immersing the main electrical unit in water, spraying liquid into electrical components, or using cleaning products that are not approved for the appliance.
Pay particular attention to visible grease and crumbs, especially after preparing fatty foods or heavily breaded ingredients. Make sure removable parts are completely dry before putting them back in place.
If the air fryer begins producing persistent smoke, stop cooking and switch it off safely. Once it has cooled, inspect it for accumulated grease, burnt food, or other obvious causes. If the smoke continues despite proper cleaning, discontinue use and consult the manufacturer's troubleshooting guidance.
A clean appliance is easier to maintain and can help prevent avoidable cooking problems. Regular care is much simpler than trying to remove a thick layer of baked-on grease later.
6. Use Only Cookware and Accessories Suitable for Your Model
Some people place small baking dishes, foil, parchment paper, or other accessories inside an air fryer to make cooking more convenient. These items can be useful, but they should be used carefully.
Not every container that is safe in a conventional oven is suitable for every air fryer. The available space, temperature rating, airflow design, and manufacturer's restrictions all matter.
If you want to use a small dish for cake, vegetables, or other ingredients, check that it is explicitly suitable for the appliance and leaves enough room for hot air to circulate. A container that blocks too much of the airflow can affect cooking performance.
Parchment paper should be used only when permitted by the appliance instructions and in a way that prevents it from contacting the heating element. Never place loose parchment paper in a preheating air fryer without food weighing it down if the manufacturer warns against this practice. The fan can lift lightweight paper toward the heating element, creating a fire risk.
Aluminum foil may also be restricted or permitted only under particular conditions. Follow the model's instructions rather than assuming it is safe in every situation. Avoid covering areas that need to remain open for airflow.
Plastic containers, ordinary paper plates, and cookware without an appropriate heat rating should not be placed inside the appliance. Materials that soften, melt, or ignite at high temperatures can damage the machine or create a safety hazard.
When in doubt, use the basket and accessories supplied or recommended by the manufacturer. A little caution can prevent damage and help the appliance operate as intended.
7. Know When the Conventional Oven Is Still the Better Choice
An air fryer is convenient, but there are situations in which a conventional oven remains the more practical option.
When preparing a large family meal, a full-size oven can accommodate bigger trays, larger cuts of meat, and multiple dishes. Trying to cook the same amount in a small air fryer may require several batches, making the process less convenient.
