How to Clean an Air Fryer Oven: Step-by-Step

An air fryer oven is a versatile countertop appliance that combines air frying, baking, roasting, and dehydrating. Over time, grease and food particles accumulate inside the cooking chamber and on the heating element, which can cause smoke, unpleasant odors, and reduced performance. Regular cleaning keeps it hygienic, prevents lingering smells, and extends the life of the appliance. This guide covers everything from daily wipe-downs to deep cleaning, with safety tips and solutions for stubborn grime.

What You’ll Need

Soft sponge or non-abrasive cloth
Mild dish soap
Warm water
Baking soda (for tough grease)
White vinegar (optional, for odors)
Soft-bristled brush or old toothbrush
Cotton swabs or pipe cleaners
Clean, dry towel

Step-by-Step

Unplug and cool down. Always disconnect the air fryer oven from the power outlet and wait until it is completely cool to the touch. Cleaning a hot appliance is dangerous and can cause burns or damage.
Remove all removable parts. Take out the basket, tray, rack, and any other detachable accessories. Check your manual for specific parts—most are dishwasher-safe, but hand washing is gentler and preserves the non-stick coating.
Wash removable parts. Fill your sink with warm water and a few drops of mild dish soap. Submerge the parts and scrub gently with a soft sponge. For baked-on food, let them soak for 10–15 minutes before scrubbing. Rinse thoroughly and set aside to dry.
Wipe the interior. Dip a soft cloth or sponge in warm soapy water, wring it out well, and wipe the inside of the cooking chamber. Pay attention to the bottom and corners where crumbs and grease collect. Do not use harsh scrubbers or abrasive cleaners—they can scratch the non-stick surface.
Clean the heating element and fan. With a soft-bristled brush or a dry cloth, gently brush off any loose debris from the heating coil and the fan guard. Do not use water directly on these parts; moisture can damage the electrical components. For stuck-on grease, use a cotton swab dipped in a little vinegar or soapy water, then wipe with a dry cloth.
Wipe the exterior. Clean the outside of the appliance with a damp cloth and mild soap. Avoid getting water into the vents or control panel. Dry with a clean towel to prevent streaks.
Dry and reassemble. Ensure all parts are completely dry before putting them back. Moisture can cause rust or electrical issues. Place the removable parts back into the air fryer oven.
Run a quick dry cycle. If you notice any lingering odors, plug in the appliance and run it empty at 180°C (350°F) for 3–5 minutes. This burns off any remaining residue and leaves the interior fresh.

Common Mistakes

Cleaning while hot: Always wait for the appliance to cool completely. Hot surfaces can cause burns, and sudden temperature changes may warp parts.
Submerging the main unit: Never immerse the base or any part with electrical components in water. This is a fire and shock hazard.
Using abrasive cleaners: Steel wool, scouring pads, and harsh chemical cleaners can scratch the non-stick coating and damage the interior.
Skipping the heating element: Grease on the heating element is a common cause of smoke. Ignore it and you’ll get unpleasant fumes during cooking.
Putting parts in the dishwasher if not marked safe: Some baskets have a non-stick coating that can degrade in the dishwasher. Always check the manual.

Tips

Clean the air fryer oven after every 3–5 uses, or immediately after a greasy meal like bacon or chicken wings.
Line the bottom tray with aluminum foil or parchment paper to catch drips and make cleanup faster. Never cover the basket entirely—airflow is essential.
Use a silicone brush to apply a paste of baking soda and water on stubborn grease spots. Let it sit for 15 minutes, then scrub gently.
Wipe the interior with a dry cloth after each use to remove loose crumbs before they bake on.
Check the crumb tray (if your model has one) and empty it regularly—it can become a fire hazard if overloaded.

Troubleshooting

Smoke coming from the air fryer oven: This usually means there is grease or food residue on the heating element. Unplug, cool, and clean the element with a brush. If smoke persists, check for any food stuck in the fan area.
Unpleasant odor after cleaning: Run a dry cycle at 180°C for 5 minutes. If the smell remains, wipe the interior with a cloth dipped in white vinegar and let it air dry.
Stubborn, baked-on grease: Make a paste of baking soda and water, apply to the affected area, and let it sit for 15–20 minutes. Scrub with a soft brush, then wipe clean.
Non-stick coating peeling: This can happen from abrasive cleaning or dishwasher use. If the coating is flaking, stop using the basket and contact the manufacturer for a replacement—flakes can mix with food.
Water in the control panel: If moisture gets into the display or buttons, unplug immediately and let it dry completely for 24 hours before using again.

Frequently Asked Questions

Can I put the air fryer basket in the dishwasher?

It depends on the model. Many baskets are dishwasher-safe, but the non-stick coating can wear off faster. Check your manual—if it doesn’t say dishwasher-safe, hand wash with warm soapy water.

How often should I clean my air fryer oven?

For regular use, clean the removable parts and interior every 3–5 uses. If you cook greasy foods, clean it after each use to prevent smoke and buildup.

Can I use oven cleaner on my air fryer oven?

No. Oven cleaners are too harsh and can damage the non-stick coating and leave toxic residues. Stick to mild dish soap, baking soda, and vinegar.

Why does my air fryer oven smell like burnt plastic?

A burnt plastic smell on first use is normal as the protective oils burn off. If it persists, it may be from food residue or a manufacturing defect. Wipe the interior and run a dry cycle; if the smell continues, contact the manufacturer.

Can I clean the heating element with water?

No, avoid water on the heating element or fan. Use a dry brush or a cloth with a tiny bit of vinegar on a cotton swab, then dry immediately.

What if my air fryer oven has a permanent stain inside?

Stains from grease or food can be stubborn. Make a baking soda paste, apply it, let it sit for 20 minutes, then scrub gently. If the stain remains, it’s cosmetic and won’t affect performance.
