Why your air fryer smell like plastic? What to do before cooking

A new air fryer should make cooking easier, not make your kitchen smell strange. But many first-time users notice something unexpected during the first few uses: an odour that smells like plastic, chemicals or a 'new appliance' smell.

The good news: a mild odour during the first use can be normal for many worktop cooking appliances. It may come from manufacturing residue, protective packaging, dust or materials heating for the first time. Some manufacturers and cooking guides recommend washing removable parts, drying them fully, placing the unit with proper ventilation and running an empty cycle before cooking food.

However, not every smell should be ignored. A faint new-appliance odour is different from smoke, melting, strong burning smells or odours that continue after proper cleaning.

This guide explains why your air fryer smells like plastic, what is normal, what is not, and how to reduce the odour safely without damaging the appliance.

Why does my air fryer smell like plastic?

When people say their air fryer smells like plastic, they are usually describing a 'plastic-like', chemical or new-appliance odour. That smell does not always mean something is melting. In many cases, it comes from one of the following causes.

1. New-appliance odour

A brand-new air fryer may release a light odour the first time it heats up. This can happen when internal surfaces, heating components, coatings or manufacturing residues are exposed to heat for the first time.

This type of smell is usually mild and should fade after the first few heating and cleaning cycles.

2. Packaging or protective material left behind

Small pieces of packaging can sometimes remain inside the basket, tray, drawer or around removable accessories. Stickers, plastic film, foam inserts, tape or paper labels may create a strong odour if heated.

Before first use, always remove all packaging and inspect the basket, crisper plate, tray and cooking chamber carefully.

3. Manufacturing residue or dust

Like many new kitchen appliances, an air fryer may have light residue or dust from production, shipping or storage. Washing removable parts and wiping the interior before first use helps reduce this.

Food & Wine recommends washing and drying removable pieces before first use and keeping the air fryer at least six inches away from walls for ventilation and cooling.

4. Food grease or residue from previous cooking

If the smell appears after several uses, it may not be a new-appliance smell at all. Grease, oil splatter, crumbs, marinades or stuck-on food can overheat and create unpleasant odours.

COSORI’s cleaning guidance notes that odours are often related to food or grease build-up and recommends regular cleaning of the basket, crisper plate and interior.

5. Washing-up liquid residue or cleaning product residue

Using too much washing-up liquid, not rinsing removable parts well or using harsh cleaners can leave residue behind. When heated, residue may produce a smell that seems chemical or plastic-like.

For this reason, it is best to use mild washing-up liquid, warm water and a soft sponge unless your user manual says otherwise.

6. Restricted airflow or blocked vents

Air fryers rely on strong air circulation. If the unit is too close to a wall, the vents are blocked or liners cover the airflow path, heat may build up and create odours.

Never block the heating element, vents or air circulation path with foil, baking paper, liners or oversized accessories. COSORI warns that foil should not cover vents or the heating element because restricted airflow can affect cooking and ventilation.

Is it normal if an air fryer smells like plastic?

A light odour during the first use can be normal, especially if the appliance is brand new. Some manufacturers recommend running the air fryer empty before cooking to help clear a new-appliance odour. Simply Recipes notes that this may create a slight chemical smell and recommends opening windows or using ventilation.

But the smell should not be intense, smoky or persistent.

Usually normal

It is usually less concerning when:

• the smell is mild;
• the air fryer is brand new;
• the odour appears during the first one to three heating cycles;
• there is no smoke, melting, sparking or visible damage; and
• the smell fades after washing, drying and airing out.

Stop using the air fryer if you notice this

Unplug the air fryer and let it cool if you notice:

• smoke that is not clearly from food;
• a strong burning or melting smell;
• visible warping, bubbling, discolouration or damaged parts; and
• electrical smells, sparks or unusual noises.

A smell that continues after several proper cleaning and empty heating cycles.

The exterior becomes unusually hot in areas not expected to heat.

When in doubt, stop using the appliance and contact the manufacturer’s customer support. Do not try to repair electrical or heating components yourself.

What to do before using a new air fryer

Before cooking food in a new air fryer, follow these steps.

Step 1. Remove all packaging

Take out the basket, tray, crisper plate, racks, inserts, cardboard, foam, plastic wrap, stickers and protective films.

Check around:

• the basket
• the crisper plate
• the drawer
• the heating area
• the back and side vents
• any removable accessories.

Do not assume everything was removed during unboxing. Small packaging pieces are easy to miss.

Step 2. Wash removable parts

Wash the basket, crisper plate, tray and other removable food-contact parts with warm water, mild washing-up liquid and a soft sponge.

Avoid metal utensils, steel wool, abrasive pads and harsh cleaners. Philips advises using hot water, washing-up liquid and a soft sponge for air fryer pans and baskets, and warns against metal tools or abrasive cleaning materials because they can damage non-stick coating.

Step 3. Rinse and dry completely

Rinse away all washing-up liquid. Then dry every part fully before reassembling the air fryer.

Moisture trapped in the drawer or under the tray can create steam and carry odours during heating.

Step 4. Wipe the interior

With the appliance unplugged and cool, wipe the inside with a soft damp cloth. Avoid soaking the main unit or getting water into electrical areas.

Never submerge the air fryer base in water.

Step 5. Place it in a ventilated area

Put the air fryer on a heat-resistant surface with open space around it. Food & Wine recommends keeping the appliance at least six inches away from walls for ventilation and cooling.

Open a window or turn on an extractor fan if you are doing the first empty cycle.

Step 6. Run an empty first-use cycle if your manual allows it

Many users reduce new-appliance odour by running the air fryer empty before cooking. Use the time and temperature recommended in your user manual.

If your manual does not provide a specific burn-off instruction, a conservative approach is to run a short empty cycle at a moderate cooking temperature, then let the unit cool and air out.

Do not leave the appliance unattended.

How to get rid of plastic-like smell in an air fryer

If the smell remains after the first setup, use the following safe troubleshooting steps.

1. Repeat the wash-dry-air-out process

• Remove the basket and accessories.
• Wash removable parts with warm soapy water.
• Rinse thoroughly.
• Dry completely.
• Leave the basket or drawer open for ventilation.

Sometimes the odour is simply trapped in the enclosed drawer.

2. Run another empty cycle with ventilation

• After cleaning and drying, run another empty cycle only if the user manual allows it.
• Keep the kitchen ventilated.
• Let the appliance cool between cycles.
• Do not run repeated long high-heat cycles back to back unless the manual says it is safe.

3. Check for hidden food or grease build-up

If the air fryer is not new, inspect for:

• oil residue under the crisper plate
• crumbs near the heating element
• grease on the drawer walls
• sticky residue in corners
• food stuck to racks or skewers.

Odours often return when leftover grease reheats. Clean after each use to prevent build-up.

4. Clean the heating area carefully

Only clean the heating area when the air fryer is unplugged and completely cool.

Use a soft sponge, damp cloth or soft brush if your manual allows it. Make sure the heating area is completely dry before turning on the air fryer.

• Do not scrape aggressively.
• Do not spray cleaners directly into the appliance.
• Do not use oven cleaner unless your manual specifically allows it.

5. Avoid harsh odour-removal hacks

Some online tips suggest heating vinegar, lemon juice or other acidic mixtures inside the air fryer. Be careful with this advice.

Acidic ingredients may not be suitable for every material, coating, seal or accessory. A safer default is to use warm water, mild washing-up liquid and a soft sponge. If your manual specifically allows diluted vinegar, use it only as directed and wipe/rinse/dry thoroughly afterwards.

For brand safety and appliance longevity, do not recommend boiling or steaming acids inside the basket as a universal solution.

What not to use when cleaning air fryer odours

To protect the basket, coating, seals and heating area, avoid:

• steel wool
• metal scrapers
• abrasive powders
• oven cleaner
• bleach
• strong chemical degreasers not approved by the manual
• excessive vinegar or lemon juice
• dishwasher use unless your manual says the part is dishwasher safe.

Cosori specifically warns against metal utensils and abrasive cleaning materials on non-stick-coated air fryer parts.

When cleaning, gentle and consistent is better than aggressive.

Can you cook food if the air fryer still smells like plastic?

If the odour is mild, the air fryer is new and you have already removed packaging, washed removable parts, dried everything and completed the recommended first-use cycle, the appliance may be ready to use.

However, do not cook food if:

• the smell is strong or worsening;
• you see smoke with no food inside;
• you notice melting, warping or visible damage;
• the odour smells electrical or like burning wires; or
• the smell remains after several cleaning and airing cycles.

In those cases, stop using the air fryer and contact the manufacturer.

How many uses until the plastic smell goes away?

A mild new-appliance odour often improves after the first few uses. The exact timing depends on the model, materials, cleaning, ventilation and how long the appliance was stored before use.

If the smell is still strong after several proper cleaning and empty heating cycles, it is worth contacting customer support rather than continuing to use the appliance.

A persistent smell may come from residue, trapped grease, incorrect accessories, blocked airflow or a product issue that needs inspection.

How to prevent air fryer smells in the future

Once the initial odour is gone, regular maintenance is the best prevention.

Clean after every use

Food & Wine recommends cleaning the basket or tray after each use and wiping the interior regularly to prevent grease build-up.

After cooking:

• let the air fryer cool;
• remove the basket and tray;
• wash removable parts;
• wipe splatter inside the drawer; and
• dry completely before storing.

Avoid overcrowding the basket

Overcrowding can cause uneven cooking, more grease splatter and trapped food debris. Give food enough space for air to circulate.

Use liners correctly

Baking paper or liners can help with cleanup, but they must not block airflow or touch the heating element. COSORI notes that baking paper should not touch the heating element, and foil should not cover vents or the heating element.

Never run the air fryer with loose baking paper and no food on top. It can lift up into the heating element.

Let the basket air out

After cleaning and drying, leave the drawer slightly open for a while before storing. This helps prevent trapped moisture and stale odours.

Use the right amount of oil

Too much oil can splatter, smoke and leave sticky build-up. Use only the amount needed for the recipe.

FAQs

Final takeaway

If your air fryer smells like plastic, start with the safest explanation first: it may be a temporary new-appliance odour, packaging residue or manufacturing dust. Wash removable parts, dry everything fully, keep the appliance well ventilated and follow the first-use instructions in your manual.

If the smell is strong, smoky, electrical, or does not improve after proper cleaning, stop using the appliance and contact the manufacturer. Avoid harsh cleaning hacks, especially universal vinegar or lemon steam methods, because different materials and coatings require different care.

A clean, well-ventilated air fryer should smell neutral during normal cooking – so when in doubt, clean gently, check the manual and prioritise safety over shortcuts.
