1. Why Cleaning Your Air Fryer Matters More Than You Think

Most air fryer owners use their machine for months before giving it a proper clean. They wipe the basket, maybe run it through the dishwasher once, and call it done. What they do not see is the grease accumulating on the heating element, the fan blades collecting airborne grease particles, and the interior walls of the cooking chamber building up a fatty residue that becomes progressively harder to remove.

This hidden grease buildup has three significant consequences that most users do not connect to cleaning:

Smoke and burning smells. When grease on the heating element reaches its smoke point, it produces visible smoke and acrid smells that transfer to your food. The first sign of inadequate cleaning is usually smoke during cooking, even when you are cooking clean items like vegetables.

Reduced cooking efficiency. Grease is an insulator. When it coats the heating element and the interior surfaces of the cooking chamber, the element must work harder to reach and maintain temperature. This raises energy consumption, extends cooking times, and creates hot spots that produce uneven results.

Off flavours in food. The layer of old grease and residue from previous cooks will impart subtle off flavours to your new meals. This is the most insidious problem — most users do not realise their food tastes stale or off-flavoured because they have never used the air fryer when it was genuinely clean.

The solution is not complicated, but it does require understanding that the air fryer has distinct zones that need different cleaning approaches. The basket is dishwasher-safe. The heating element requires dry-brush cleaning only. The fan area needs compressed air or a dry brush. The main housing requires a damp, not wet, cloth.

This guide is the comprehensive reference for keeping your air fryer clean, efficient, and free of contamination.

2. Understanding What Each Part Can and Cannot Handle

Before cleaning, you need to understand which parts of your air fryer can handle water and which absolutely cannot.

Dishwasher-Safe Parts

These parts can be submerged, run through a dishwasher, or scrubbed with liquid cleaners:

Cooking basket — the removable basket that holds food
Crisper plate/tray — the perforated plate that sits inside the basket
Any accessories — racks, Muffin trays, pizza stones (unless specified otherwise)

Hand-Wash Only (Warm Soapy Water)

These parts can be hand-washed but not dishwasher-cleaned:

Basket handle and latch mechanism — the click-together mechanism on the front of some baskets. Dishwasher detergents can degrade the plastic latch over time.
Rack with non-detachable handles — if the rack has plastic or silicone handles, wash by hand

Damp Cloth Only

Never submerge these areas, use only a barely damp cloth:

Heating element area — the coil or metal plate at the top of the cooking chamber
Interior walls of the cooking chamber — the metal walls of the main unit
Fan housing interior — visible through the vents

Never Wet

These areas must remain dry:

Main unit body — the outer housing with the control panel
Fan motor — located behind the rear vent panel
Control panel and display — any electrical components
Electrical connections — where the basket contacts the main unit

Understanding these zones prevents the most common cleaning mistakes that damage air fryers or create safety hazards.

3. Complete Deep Clean Procedure

Follow this procedure for a complete deep clean. Perform every 2-4 weeks depending on usage.

Before You Begin: Safety First

Unplug the air fryer completely
Allow the unit to cool for at least 30 minutes — never clean a hot air fryer
Remove the basket and all removable accessories
Set up your cleaning station: sink or large bowl, warm water, dish soap, a nylon brush, and a dry towel

Step 1: Basket and Crisper Plate (15 minutes)

Disassembly: Remove the crisper plate from the basket. Some baskets have the crisper plate as a separate piece, others have a wire rack that lifts out.

Pre-soak: Fill your sink or a large bowl with hot water and 2 tablespoons of dish soap. Submerge the basket and crisper plate and let them soak for 10 minutes. This loosens grease and food residue before scrubbing.

Scrub: Use a nylon scrub brush (not metal, which damages non-stick coatings) to clean all surfaces. Pay particular attention to:

The underside of the crisper plate (where grease drips through the perforations)
The basket corners and edges (where residue accumulates)
The handle mechanism (clean around, not inside, the latch)

Rinse: Rinse thoroughly with hot water to remove all soap residue. Soap residue, if left, will smoke during the next cooking cycle.

Dry: Place basket and plate on a clean towel to air dry, or dry immediately with a microfibre cloth. Do not reassemble while damp.

Dishwasher option: Both the basket and crisper plate are dishwasher-safe. Dishwasher cleaning is acceptable but hand washing produces better results for the heating element area because the dishwasher does not clean the cooking-chamber-side surfaces.

Step 2: Interior Cooking Chamber (10 minutes)

Inspection: With the basket removed, look inside the cooking chamber. You are looking for grease buildup on the walls, residue around the heating element area, and any debris in the bottom of the chamber.

Dry brushing: Use a dry stiff nylon brush to gently remove loose grease and debris from the interior walls of the cooking chamber. Work from top to bottom. Pay attention to the area around the heating element.

Damp cloth wipe: Dampen a soft cloth with warm water (barely damp — you should not be able to wring water from it). Wipe the interior walls and the floor of the cooking chamber. Use a second pass with a dry cloth immediately after to remove moisture.

Important: Never use liquid cleaners, sprays, or submerge anything in this area. The interior of the main unit contains electrical components that must not get wet.

Step 3: Heating Element Cleaning (5 minutes)

Safety check: Ensure the unit is completely cool and unplugged.

Dry brush only: Use a dry stiff nylon brush to gently clean the heating element. The goal is to remove accumulated grease from the surface of the element — not to scrub it aggressively, but to reduce the buildup that causes smoking.

For coil-style elements: brush along the coils in a single direction to avoid bending them. For flat surface elements: brush in gentle strokes parallel to the surface.

Stubborn residue: If grease is stubborn and will not brush off, dampen a cloth with a small amount of white vinegar, apply to the residue, let it sit for 2-3 minutes, then brush clean. Do not use abrasive scouring pads on the heating element.

Step 4: Fan Area Cleaning (5 minutes)

Locate the fan: On most air fryers, the fan is accessible either through the cooking chamber (looking up from below) or through a rear vent panel. On Ninja models, the fan is behind the front grille area.

Dry brush or compressed air: Use a can of compressed air (available at any electronics store) to blow dust and debris from the fan blades. Hold the can upright and use short bursts. Alternatively, use a dry soft brush to carefully wipe each blade.

Do not: Use wet cloths, liquid cleaners, or submerge the main unit. Keep all cleaning to the dry brush or compressed air approach.

Step 5: Exterior Cleaning (5 minutes)

Main body: Wipe the outer housing with a soft cloth dampened with warm water. Clean the control panel with a dry microfibre cloth — never use wet cloths on electrical controls.

Basket area: Wipe the channel where the basket slides into the housing. This channel accumulates food debris and grease that can prevent the basket from seating properly, causing error codes.

Vent areas: Use a dry brush to clean the rear and side vent grilles. Blocked vents are a primary cause of overheating.

4. Heating Element and Fan Cleaning

Why the Heating Element Is the Most Critical Area

Grease on the heating element is the primary cause of smoking during cooking. The element operates at 400°F or higher, and when grease reaches this temperature, it carbonises, smokes, and produces a burnt smell that contaminates your food. Over time, heavy grease buildup forces the element to work harder to reach temperature, reducing efficiency and shortening the element's lifespan.

Tools for Heating Element Cleaning

Nylon brush (recommended): A stiff nylon brush removes grease without damaging the element surface. Available at kitchen supply stores or online.

Dry lint-free cloth: For wiping loose debris after brushing.

White vinegar (for stubborn residue): Apply sparingly to a cloth, not directly. Vinegar dissolves grease acids effectively.

Compressed air: Useful for blowing debris from fan areas before it accumulates.

What Not to Use on a Heating Element

Metal brushes or scouring pads
Abrasive cleaners or baking soda paste directly on the element
Liquid cleaners or water
Anything that could bend or damage the element coils

5. Removing Stubborn Grease and Odours

Stubborn Grease on Basket

If the basket has heavy grease buildup that soap and brushing cannot remove:

Make a paste of baking soda and water
Apply the paste to the affected areas
Let it sit for 20 minutes
Scrub with nylon brush
Rinse thoroughly

Note: Do not use this method on the heating element.

Smoke and Burning Smell

If your air fryer smokes during cooking even with a recently cleaned basket:

Allow the unit to cool completely
Perform a deep clean of the heating element area
Check the fan area for grease accumulation
Run the empty unit at 400°F for 5 minutes to burn off any remaining residue

If smoking persists after deep cleaning, the heating element may be damaged or the fan may not be operating correctly.

Persistent Food Odours

To neutralise odours from previous cooks:

Lemon method:

Cut a lemon in half
Air fry the lemon halves at 400°F for 5-6 minutes
The citric acid vapourises and neutralises cooking odours

Baking soda method:

Place 2 tablespoons of baking soda in the basket
Air fry at 350°F for 10 minutes
The baking soda absorbs and neutralises acidic odours

Vinegar method:

Soak a cloth in white vinegar
Place the cloth in the basket
Air fry at 350°F for 10 minutes
Vinegar is a degreaser and deodoriser

New Air Fryer Burn-Off

A brand-new air fryer will produce smoke and a plastic/rubber smell for the first 2-3 uses as manufacturing oils and residues burn off the heating element. This is normal and temporary. To accelerate the burn-off:

Run the empty air fryer at 400°F for 5 minutes
Allow to cool for 10 minutes
Repeat 2-3 times

The unit will smoke and smell during this process. Ensure good ventilation during burn-off.

6. Maintenance Schedule

After Every 3-4 Uses: Light Clean

Remove basket and wipe or rinse

7. Cleaning Troubleshooting

Problem	Likely Cause	Solution
Smoke during cooking	Grease on heating element	Perform full deep clean, especially heating element
Persistent smell after cleaning	Residual grease in fan area	Clean fan area with compressed air or dry brush
Bubbles or peeling on basket coating	Non-stick coating failure	Replace basket
Sticky residue on basket	Soap buildup from dishwasher or inadequate rinsing	Scrub with baking soda paste, rinse thoroughly
White residue on basket	Hard water deposits or dishwasher detergent buildup	Soak in white vinegar for 15 minutes, rinse
Streaking or residue on interior	Cleaner residue not wiped dry	Wipe interior with damp cloth, then dry cloth
Error code E4 (basket not detected)	Debris blocking basket channel	Clean basket channel with dry brush or cloth
Rust-coloured spots on stainless parts	Minor surface corrosion (normal)	Scrub gently, dry immediately; not a safety concern
Discolouration on heating element	Normal oxidation from heat use	Do not attempt to remove — not a safety concern

8. Replacing Worn Parts

When to Replace the Basket

The non-stick coating on air fryer baskets degrades over time. Replace when:

You see significant scratching or chipping in the coating
Food sticks persistently even when properly oiled
The coating is peeling or flaking

Replacement baskets for major brands (Ninja, Cosori, Instant Pot) are available on Amazon and through manufacturer websites. Always buy manufacturer-recommended replacement parts for your specific model.

When to Replace Non-Stick Accessories

Silicone molds and accessories that show surface deterioration, permanent staining, or warping should be replaced. While worn silicone is not a safety hazard, it becomes increasingly difficult to clean and may affect cooking performance.

When to Replace the Entire Unit

Replace the air fryer if:

The heating element shows visible corrosion or breakage
The unit sparks, smokes when not cooking, or shows electrical damage
The fan is not operating (audible during use)
The non-stick coating is significantly degraded and you cook frequently

9. Frequently Asked Questions

How often should you deep clean an air fryer?

A light clean (wiping the basket and exterior) should happen after every 3-4 uses. A deep clean (full disassembly and cleaning of all components) should happen every 2-4 weeks depending on usage frequency. For daily use, a deep clean every 2 weeks is recommended. If you notice smoke, burning smells, or reduced performance, a deep clean is overdue.

Can you submerge the air fryer basket in water?

The basket and crisper plate are dishwasher-safe and can be submerged or run through a dishwasher cycle. The main unit (the housing with the heating element and fan) should never be submerged in water or placed in a dishwasher. Wipe the heating element area with a damp cloth only, never wet enough to drip water into the electronics.

What is the best way to clean the heating element in an air fryer?

Clean the heating element only after the unit has completely cooled. Use a dry stiff nylon brush (not metal) to gently remove grease buildup from the coils or surface. A slightly damp cloth can be used if the cloth is barely damp — no dripping water. For stubborn grease, dampen the cloth with a small amount of white vinegar.

Why does my air fryer smoke during cooking?

Smoke from an air fryer is almost always caused by grease accumulation on the heating element or in the cooking chamber. When grease heats to smoking point, it produces smoke and unpleasant smells. The first sign of inadequate cleaning is usually smoke during cooking, even when you are cooking clean items like vegetables. Persistent smoking indicates a need for deep cleaning. New air fryers also produce smoke for the first 2-3 uses as manufacturing residues burn off — this is normal and temporary.

Can you use baking soda to clean an air fryer?

Baking soda paste (mixing baking soda with a small amount of water) is excellent for cleaning the basket and crisper plate, especially for stubborn grease. Apply the paste, let it sit for 15-20 minutes, scrub with a soft nylon brush, and rinse thoroughly. Do not use baking soda on the heating element area — the abrasive paste can damage the element surface.

How do you clean grease out of an air fryer fan?

To clean the fan, unplug the unit and access the fan through the cooking chamber or from the rear vent panel (depending on model). Use a can of compressed air to blow dust and loose debris from the fan blades, or use a soft dry brush to carefully wipe each blade. Never submerge the main unit or use liquid cleaners near the fan motor.

Is the non-stick coating on air fryer baskets safe?

Most modern air fryer baskets use PTFE (polytetrafluoroethylene) non-stick coatings that are considered safe for normal use when not scratched or overheated. PFOA (a related compound of concern) has been largely eliminated from cookware coatings since 2013. Ceramic non-stick coatings (used by Ninja) are also considered safe and are more scratch-resistant than PTFE.

How do you remove bad smells from an air fryer?

To remove persistent odours, bake a solution of 2 tablespoons baking soda + ½ cup water in the basket at 350°F for 10 minutes. Alternatively, air fry a cut lemon at 400°F for 5-6 minutes. Both methods neutralise cooking odours. For new air fryers, 2-3 empty cooking cycles at 400°F for 5 minutes each burns off manufacturing residues.
