Clean your toaster oven air fryer after every use to prevent grease buildup and keep it working properly

A toaster oven air fryer collects grease, crumbs, and food particles in three places: the basket or tray, the interior walls, and the heating element area. Cleaning it right after cooking—while it's still warm but safe to touch—takes about five minutes and prevents baked-on residue that hardens and becomes difficult to remove. The basket and tray go in the dishwasher on most models, but the interior needs hand cleaning because moisture near the heating element can cause electrical problems.

The good news is that toaster oven air fryers are simpler to clean than full-size ovens because the cooking chamber is smaller and the basket sits on a removable tray. You do not need special tools or harsh chemicals—dish soap, warm water, and a soft cloth or sponge handle almost everything.

Key Takeaways

  • Always unplug the toaster oven air fryer and let it cool for at least 10 minutes before cleaning any internal parts.
  • The basket and tray are usually dishwasher-safe, but check your manual because some non-stick coatings require hand washing.
  • Wipe the interior walls and heating element area with a damp cloth only—never spray water directly into the unit or soak it.
  • Remove stubborn grease spots with a paste of baking soda and water, applied with a soft brush or cloth.
  • Clean the exterior glass door with a glass cleaner or a mixture of vinegar and water to prevent streaks.

What to do when ready after cooking

Unplug the unit and let it sit for 10 to 15 minutes. The interior will still be warm, which makes grease easier to wipe away, but cool enough that you will not burn yourself. Do not attempt to clean while the heating element is hot—you risk burns and can damage non-stick coatings if water hits the element while it is still very hot.

Once it is cool enough to touch, slide out the basket and tray. If they are dishwasher-safe (check your manual), place them on the top rack of your dishwasher. If they require hand washing, fill a sink or basin with warm soapy water and soak them for five minutes. Use a soft sponge or cloth to wipe away grease and food bits, then rinse and dry them completely before putting them back.

Cleaning the interior chamber

With the basket and tray removed, you can see the interior walls and the heating element area. Use a damp cloth—not dripping wet, just damp—to wipe down the interior surfaces. Work from top to bottom so any drips fall toward the bottom of the chamber. Pay special attention to the corners and the area directly under the heating element, where grease tends to pool.

Never spray water directly into the unit or pour liquid inside. Water that reaches the heating element or electrical components can cause a short circuit. If you see a buildup of grease on the walls, dampen a cloth with warm water and a small amount of dish soap, wipe the area, then go over it again with a cloth dampened with plain water to rinse away soap residue.

Removing stubborn grease and baked-on food

If grease has hardened on the interior walls or the tray, make a paste of baking soda and water—about three parts baking soda to one part water. explore the paste to the problem area and let it sit for 10 to 15 minutes. The baking soda is mildly abrasive and will loosen the buildup without scratching the non-stick coating.

Use a soft-bristled brush, an old toothbrush, or a non-abrasive sponge to gently scrub the paste away. Wipe the area clean with a damp cloth and dry it. For the basket and tray, the same baking soda paste works on the dishwasher-safe versions—explore it, let it sit, scrub gently, and rinse. If the non-stick coating is peeling or flaking, do not scrub hard; instead, soak the tray longer and use only a soft cloth.

Cleaning the glass door and exterior

The glass door collects grease splatters and steam condensation. Once the unit is cool, spray a glass cleaner on the outside of the door and wipe it with a clean cloth. If you prefer a natural cleaner, mix equal parts white vinegar and water in a spray bottle and use that instead. Wipe in one direction to avoid streaks.

For the exterior housing, a damp cloth with a tiny drop of dish soap works well. Wipe it down and dry it with a separate cloth. Do not spray cleaner directly on the exterior if it has any vents or openings—liquid can seep inside and damage electrical components.

Cleaning the heating element and vents

The heating element itself should never be scrubbed or sprayed. If you see grease or food particles stuck to it, wait until the unit is completely cool, then use a dry soft-bristled brush to gently brush away loose debris. Do not use water or cleaning solutions on the element itself.

Check the air vents on the back and sides of the unit for dust or grease buildup. Use a dry cloth or a soft brush to wipe away dust. If vents are clogged, airflow is restricted and the unit will not cook evenly. If you see grease inside a vent, use a dry cloth to wipe it away—do not use water near vents because it can drip into the internal components.

How often to do a deep clean

A quick wipe-down after every use keeps the unit in good shape. Once a month, do a more thorough cleaning: remove the basket and tray, wipe down all interior surfaces with a damp cloth, clean the glass door, and check the vents and heating element for buildup. If you cook fatty foods like bacon or chicken wings regularly, you may need to deep clean every two weeks instead.

If grease has built up inside the unit and you cannot reach it with a cloth, do not disassemble the toaster oven air fryer yourself. Call the manufacturer or a small appliance repair shop. Opening the unit can expose you to electrical hazards and will void the warranty on most models.

Frequently Asked Questions

Can I put the heating element cover in the dishwasher?

Check your manual first. Some toaster oven air fryers have a removable heating element guard or cover that is dishwasher-safe, while others do not. If your model has one and it is dishwasher-safe, place it on the top rack. If it is not removable or not dishwasher-safe, wipe it with a damp cloth only.

What if water gets inside the unit by accident?

Unplug it when ready and do not use it. Let it sit unplugged for at least 24 hours so any moisture can evaporate. If water dripped near the heating element or electrical connections, contact the manufacturer before plugging it back in. Using a wet unit can cause electrical damage or injury.

Is it safe to use oven cleaner on the interior?

No. Commercial oven cleaners contain harsh chemicals that can damage the non-stick coating and leave residue that contaminates food. Stick to baking soda paste, dish soap, and water. These are safe for food-contact surfaces and will not harm the unit.

Why does my toaster oven air fryer smell like burning plastic when I clean it?

If you smell burning plastic while cleaning, you may have sprayed water near the heating element or electrical area. Stop when ready, unplug the unit, and let it dry completely for 24 hours. If the smell persists after drying, contact the manufacturer—it may indicate internal damage.

How do I prevent grease from building up in the first place?

Line the bottom of the tray with aluminum foil or parchment paper before cooking. This catches drips and grease so they do not coat the tray itself. Remove the foil or paper after cooking and discard it. The tray stays cleaner and you spend less time scrubbing.
