You’ve probably noticed a burning smell. Or a faint wisp of smoke from your Ninja air fryer lately. That’s almost without fail a dirty heating element caked with old grease. Left unchecked, it ruins food taste and can become a fire risk. Cleaning it safely takes more than just scrubbing blindly.
TL; DR
- Unplug, cool completely, and turn the unit upside down to access the heating coil without liquids dripping into the motor.
- Use Dawn Powerwash or a soft baking soda paste applied with a nylon brush; harsh chemicals corrode the protective coating.
- Air dry for 12 to 24 hours and run a 10-minute lemon steam cycle afterward to eliminate any residual cleaner taste.
Key Point
- Don’t skip the drying step. Moisture trapped in the heating assembly can cause immediate electrical failure when you plug the unit back in.
- The upside-down trick prevents liquid cleaners from seeping into the motor housing, a $100+ repair mistake you’ll never make twice.
- A sticky heating element cooks food unevenly and shortens the life of the appliance—clean it every 15-20 uses.
- Dawn Powerwash genuinely cuts through baked-on gunk better than any homemade spray I’ve tested.
What You’ll Need
Before you start, gather these supplies. The whole process takes about 25 minutes of active work plus a long drying wait.
- A soft-bristle toothbrush or nylon brush (no metal scrubbers, ever)
- Dawn Powerwash spray or a paste made from baking soda and water
- Microfiber cloths (2)
- A small bowl for the steam method
- Lemon slices or 2 tbsp lemon juice
- Enough counter space to flip the unit safely
Skill level: Beginner, no special tools. The biggest need is patience for that 12-24 hour drying window.
How to Clean a Ninja Air Fryer Like a Pro in 6 Simple Steps covers the basket and outer body, so if you’re doing a full deep clean, tackle that first. The heating element is a separate beast.
Step 1: Power Down and Cool Off
Never touch the heating element while the unit is plugged in or still warm. Give it at least 30 minutes after the last cook.
Unplug the air fryer from the outlet. Slide the basket out and set it aside. Wait; you’ll want to check that the heating coil is cool to the touch before moving on; even a slightly warm element can turn grease into sticky cement when you apply a cleaner.
On closer inspection, naturally, pro tip: If the coil has visible black crust that seems impossible to remove, don’t panic, and the steam step later will soften a fair number of it.
Step 2: Flip It Upside Down
Flipping the air fryer upside down is the single smartest move for cleaning the heating element.
Why? Gravity works in your favor, liquid cleaners and dislodged gunk will fall away from the motor housing.
This is exactly what that first point lead to. Carefully turn the entire unit over and place it on a stable, flat surface. You might need a towel underneath to catch any drips — now the heating coil is right away in front of you, a breeze to reach with a brush.
Over the past few years, this also gives you better visibility. Who would have thought? I’ve found that the coil’s top side regularly hosts a thick layer of char that you can’t see.
When the unit is upright. Flipping it over reveals the real mess.
Nine times out of ten. If you own a Ninja air fryer oven rather than the basket style. Check the specific How to Clean Ninja Air Fryer Oven Heating Element guide before proceeding; the upside-down trick doesn’t apply there.
Step 3: Brush Off Loose Debris
Before any liquid cleaner, use a dry soft-bristle brush to knock off loose char and food particles.
This prevents smearing wet, abrasive paste around and makes the deep clean far more effective.
Gently scrub the coil and the metal guard surrounding it. You’re not trying to polish the metal yet, just remove the a breeze stuff — hold a vacuum nozzle nearby if you’ve one; it’ll capture the falling flakes so they don’t scatter everywhere.
For the average user, i used to skip this step and go straight to spraying. Substantial mistake. As it turns out, all that loose debris turns into a sticky. Sludgy paste that’s harder to wipe away. Plus, spend two minutes here, save ten later.
Is it safe to use a brush on the heating element?
Looking at this from another angle, across the board, yes. As long as the brush is nylon or soft natural bristle, and if the (depending entirely on the context) coating is compromised.
Step 4: Steam It Loose (for Medium to Heavy Gunk)
The steam method loosens burnt-on residue without scraping, but it’s not a magical fix for extreme buildup.
Fill a small bowl with 1 cup of water and a few lemon slices, return the basket to the unit, and run the air fryer at 380°F for 10 minutes.
When the cycle ends, the interior will be filled with steamy condensation. That moisture softens the baked-on grease. Making it far easier to wipe off afterward. Open the basket carefully and let the unit cool for about 5 minutes.
You don’t burn your fingers.
Honestly, I’ve gotten mixed results with this method alone. It works brilliantly for light films of oil, but for thick. Black carbon buildup (the kind that feels like flaky plastic) you’ll still need to scrub, and think of steam as a pre-treatment, not a standalone solution.
After steaming, wipe down the interior walls with a damp microfiber cloth while they’re still warm. This catches any grease that splattered upward during cooking.
Step 5: Apply Cleaner and Scrub the Coils
Now apply your degreasing agent directly to the heating element. Dawn Powerwash or a baking soda paste are the only things I’ll use on my own Ninja.
If you’re using Powerwash, spray the coil liberally, and let it sit for 3-5 minutes. The foam will break down the fat molecules…which means as far as I know, then apply it over the greasy areas with an old toothbrush.
Scrub in circular motions, focusing on the worst spots. The coil surface isn’t fragile.
You can apply some pressure as long as you’re using a soft brush, and rinse the brush constantly in warm water, and repeat until the water runs clear off the coil.
“The heating element is the heart of the air fryer. ” Stick to mild degreasers.
What if residue is still stuck after scrubbing?
Make a second application of baking soda paste, but this time leave it on for 20 minutes before scrubbing again, and the alkaline nature of baking soda gradually breaks down stubborn carbon. Patience wins here.
Once all the grease is gone. Wipe the coil thoroughly with a damp microfiber cloth to remove every trace of cleaner. Baking soda residue, in particular, will burn, and craft a white film that smokes like crazy.
Step 6: Dry Completely and Run a Burn-off
Moisture is the enemy at this stage. Allow 12 to 24 hours of air drying before plugging the unit back in.
, wait, let me rephrase, then leave the basket out and the unit upside down in a well-ventilated area. Appliance repair technicians stress that anything less than 12 hours risks an electrical short. When you switch it on.
After drying, reassemble the air fryer, and run a 10-minute cycle at 380°F with just a bowl of water and fresh lemon slices. This burn-off eliminates any lingering cleaner odor, and the first time you use it afterward. You might notice a faint “new” smell—that’s just the protective coating off-gassing and will fade after one or two cooks.
- Unplug and wait — Make sure the unit is completely cool and disconnected before touching the coil.
- Flip it upside down — Gravity protects the motor from liquid damage.
- Dry brush first — Remove loose debris before introducing any moisture.
- Steam if needed — Use the lemon water steam method to soften stubborn buildup.
- Scrub with Dawn or baking soda paste — Apply with a nylon brush and avoid metal scouring pads.
- Air dry for 12-24 hours — Never rush this or you’ll blow the electronics.
Troubleshooting Common Mistakes
Even careful cleaners run into issues. Here are the most frequent slip-ups and how to undo them.–Residual smoke on first use: This happens when cleaner isn’t fully wiped off. Run another 10-minute lemon bowl cycle. If smoke persists, unplug and inspect the coil for hidden white residue.
- Unit won’t turn on after cleaning: Moisture likely shorted a circuit. Leave it unplugged for 48 hours in a warm spot, then try again. If still dead, contact Ninja support.
- Corrosion spots on the coil: You used a metal brush or harsh oven cleaner. The coating is damaged. Stop using the unit and order a replacement part if possible—cooking with exposed rust is unsafe.
- Weird taste in food: Residual cleaning product. Rinse the basket again and run an empty 15-minute cycle at 400°F with just water.

People Also Ask
Can I clean my Ninja air fryer heating element without taking it apart?
Yes. Consider this: the heating element on most Ninja basket air fryers is accessible from underneath.
After removing the basket and inverting the unit. No disassembly required. Just follow the steps above.
How often should I clean the heating element?
Every 15–20 relies on or whenever you notice smoke or a burning smell, and if you cook fatty foods like chicken wings or bacon a lot, clean it more a lot—around every 10 cycles. The buildup accelerates fast.
Is vinegar safe for cleaning a Ninja air fryer heating element?
To summary, blocksep matters. White vinegar diluted with water (50/50) can work for light grease. But it’s not strong enough for heavy carbon.
Stick to baking soda paste or Dawn Powerwash for real cleaning power… never use undiluted vinegar as the acid can (and that implies quite a bit) dull metal finishes over time.
My air fryer still smells after cleaning. What should I do?
Within this context. Run a 15-minute cycle with ½ cup of baking soda scattered in the (and the data generally agrees) basket (no water). This absorbs lingering odors. If the smell persists. Check underneath the heating element for hidden grease, well. Actually, pockets you (a detail constantly overlooked) may have missed.
Can water damage the heating element?
100%. While small amounts of moisture during cleaning are fine if dried properly. Leaving water pooled on the coil or dripping into internal components will cause an electrical short.
Weird, right? Always dry for at least 12 hours.
What to Do Next
You’ve cleaned the heating element, now secure that freshness.
Wipe the interior lightly after every cook. While the unit is still warm. More importantly, it takes 30 seconds and stops grease from hardening.
For the basket and crisper plate. Follow the 6-step method in the general Ninja air fryer cleaning guide. If you own the oven model, the heating element cleaning approach is different. So bookmark the oven heating element guide for when that time comes.
Honestly? The single most durable way to avoid another grimy coil is to avoid cooking sprays that leave a sticky residue. Hard to say. The key here is that switch to a refillable oil mister with a high smoke point oil like avocado. And you’ll cut cleaning frequency in half.
