Why Does My Air Fryer Smell?
Air fryers cook food by circulating hot air around it, which is fantastic for crisping and browning without all the oil. However, this same process can cause smells to build up if the appliance isn’t cleaned properly or if certain foods leave strong residues. Smells can be grouped into a few common categories:
- The new plastic or chemical smell from manufacturing
- Food odour buildup from grease, oils, and spills
- Smoke or burning smells caused by overheating or grease on the heating element
- Strong food smells from fish, garlic, or spices
Understanding what type of smell you’re dealing with is the first step towards fixing it.

The New Air Fryer Plastic Smell
Almost every new air fryer lets off a faint plastic or chemical smell during its first few uses. This is completely normal and not hazardous. The odour comes from residual protective coatings, oils, and manufacturing residues burning off as the appliance heats for the first time.
Why It Happens
During production, manufacturers often coat parts with protective oils or coatings to prevent corrosion and damage. When the air fryer is first turned on, these coatings burn away, releasing a noticeable smell. The plastic casing of the unit can also emit a faint scent when heated initially.
How to Get Rid of It
You’ll want to do a proper burn-off cycle before cooking food to clear out these smells:
- Place the air fryer on a bench with good airflow — open a window or turn on your kitchen fan.
- Run the air fryer empty at 204°C (400°F) for 20 minutes. This high heat helps burn off residues.
- Let the air fryer cool completely.
- Wash the basket and tray thoroughly with warm, soapy water.
- Repeat the empty run and wash cycle if the smell persists (usually 2-3 times is enough).
Bonus tip: Some people add a tablespoon of distilled white vinegar to a small oven-safe dish and run it inside the air fryer during the burn-off cycle. Vinegar’s natural acidity helps neutralise chemical smells effectively.
When to Worry
If the smell is strong, acrid, or causes irritation after several burn-off cycles, double-check your model for any recalls or contact the retailer. But for most brands bought from Kmart, Big W, or Harvey Norman, a few burn-off runs will do the trick.

Food Odour Buildup: The Most Common Smell Problem
After regular use, your air fryer can start to smell like old oil, stale food, or a general mustiness. This is caused by grease, oil, crumbs, and food particles that build up not only in the basket or tray but also on the heating element, fan, and interior walls.
Why It Happens
- Hot oil splatters and drips onto the heating element and fan.
- Food particles get trapped in nooks and crannies.
- Stale grease heats repeatedly, releasing unpleasant odours.
- Moisture trapped inside can cause musty smells.
How to Fix It
Keeping a clean air fryer is key. Here’s your go-to cleaning routine:
- Clean after every use:
- Deep clean weekly:
- Vinegar steam clean:
- Baking soda soak:

Smoke and Burning Smells: What’s Going On?
If your air fryer starts smoking or smells like something’s burning during cooking, it’s usually because grease has built up on the heating element or drip tray.
Common Causes
- Fatty foods like bacon, sausages, or chicken thighs drip grease.
- Grease accumulates on the heating element.
- The drip tray fills with oil, and if it’s dry, grease can burn.
- Cooking at too high a temperature can cause food or grease to burn quickly.
How to Stop It
- Add water to the drip tray: Pour a few tablespoons of water into the drip tray before cooking fatty foods. The water catches grease drips, preventing them from burning and smoking.
- Clean the heating element regularly: Use a soft brush or cloth to wipe grease from the heating element weekly.
- Lower cooking temperature: When cooking fatty foods prone to splatter, reduce the temperature by 10–20°C.
- Avoid overcrowding: Give food pieces space for air circulation to reduce smoke.
Pro Tip:
If you notice smoke when cooking something new, stop the air fryer immediately, allow it to cool, and check for leftover grease or old food bits.

Fishy or Strong Food Smells: How to Remove Lingering Odours
Certain foods leave stronger smells than others — fish, garlic, onions, and highly spiced dishes are prime culprits. These odours can cling to your air fryer and transfer to other meals if not properly cleaned.
How to Combat Strong Food Odours
- Lemon steam treatment:
- Immediate cleaning: Wash the basket and tray right after cooking strong-smelling foods to prevent smells from settling.
- Baking soda paste: Make a paste with baking soda and water, apply it to the basket, let it sit for 15 minutes, then scrub and rinse.
- Activated charcoal or coffee grounds: Place a small bowl with activated charcoal or fresh coffee grounds in the air fryer overnight to absorb odours (do not turn on the unit during this).

Prevention Is Easier Than Cure
The best way to keep your air fryer smelling fresh is to prevent odours from building up in the first place. Here are some simple prevention tips:
- Wash the basket and tray after every use: It only takes a couple of minutes and stops grease and food residues accumulating.
- Wipe out the interior weekly: Use a damp cloth to clean the inside walls and heating element area.
- Use parchment paper liners or silicone mats: These help catch spills and reduce cleaning time, especially with messy or sticky foods.
- Add water to the drip tray when cooking fatty foods: This prevents grease from burning.
- Ensure proper ventilation: Never push your air fryer flush against a wall. Leave at least 10cm of space behind to allow air flow through the vents.
- Cook strong-smelling foods separately: If possible, designate a particular air fryer basket for fish or spiced dishes to avoid cross-contamination.
- Regularly check and clean the heating element: It’s often forgotten but crucial to prevent smells and smoking.
Remember: a clean air fryer does not smell. If yours does, it’s a sure sign it needs attention.

Common Mistakes to Avoid
Even experienced air fryer users sometimes slip up, causing odour problems:
- Ignoring the heating element: Not cleaning the element lets grease build up, causing smoke and smells.
- Cooking multiple strong-smelling foods without cleaning: This leads to odour transfer and unpleasant food flavours.
- Overcrowding the basket: This reduces air circulation and can cause food to burn or smoke.
- Not ventilating the kitchen during the burn-off: Burning off the new plastic smell in a closed room traps odours.
- Using harsh chemical cleaners: These can leave residue and affect food taste; always use mild soap and natural cleaning agents like vinegar or baking soda.
- Leaving the air fryer dirty for days: This lets grease and food residues harden and smell worse.
Avoid these to keep your air fryer fresh and your meals tasting great.

Pro Tips for Odour-Free Air Frying
- Burn off new units outside of cooking times: Run the empty air fryer early on a weekend day with open windows.
- Use lemon or vinegar steam treatments weekly: This keeps smells at bay and freshens the interior.
- Invest in silicone mats made for air fryers: They’re dishwasher safe and reduce cleaning hassles.
- Rotate your air fryer’s cleaning routine: Focus on the basket, heating element, fan, and drip tray on different days.
- Store your air fryer basket separately: Let the basket air out overnight if possible.
- Don’t use aerosol sprays near your air fryer: These can settle inside and cause smells when heated.
- Check your cooking oil quality: Rancid oil causes bad smells; always use fresh oils suitable for high heat like avocado or light olive oil.
