The Simple Air Fryer Cleaning Routine That Gets Rid of Burnt Smells
If your air fryer has suddenly started smelling like burnt food even when you’re cooking something completely different, don’t ignore it. That strange smell could be coming from grease, crumbs, and old food residue hiding inside the appliance.
I learned this the annoying way. My air fryer still looked reasonably clean, so I assumed it didn’t need much attention. But after a few uses, I started noticing a burnt smell that seemed to get stronger every time I cooked.
Once I finally gave it a proper clean, the difference was obvious.
The basket looked better, the strange smell disappeared, and cooking became much more pleasant. And the best part? I didn’t need expensive cleaning products or a complicated routine.
Here’s the simple way to clean your air fryer and keep it from developing that nasty burnt smell.
Why Your Air Fryer Gets So Dirty
Air fryers circulate extremely hot air around your food, which means grease and tiny food particles can travel beyond the basket.
Over time, residue can collect around:
- The cooking basket
- The tray or crisper plate
- The inside walls
- The heating element
- Hard-to-reach corners
That buildup can eventually produce unpleasant smells, smoke, or food residue that transfers odors to your next meal.
And there’s another problem: old grease can become much harder to remove once it has been repeatedly heated.
That’s why cleaning your air fryer regularly is much easier than waiting until there’s a thick layer of baked-on residue.
How to Clean Your Air Fryer Step by Step
You don’t need a cabinet full of specialty products.
For routine cleaning, you’ll usually need:
- Warm water
- Dish soap
- Soft sponge
- Microfiber cloth
- Soft brush or old toothbrush
1. Unplug the Air Fryer and Let It Cool
Before doing anything, switch off the appliance, unplug it, and allow it to cool completely.
Don’t start cleaning while the basket or interior is still hot. Apart from the obvious burn risk, handling hot parts makes cleaning much more difficult.
2. Remove the Basket and Tray
Take out all removable cooking components.
The basket and crisper tray usually collect most of the grease, crumbs, and food residue, so give them a thorough inspection.
Check underneath the tray too. Food particles can hide in places you don’t immediately notice.
3. Soak Away Stubborn Grease
Place the removable parts in warm, soapy water.
Let them soak for several minutes if grease has hardened onto the surface.
This is much better than immediately attacking the residue with an abrasive scrubber.
Once the grease softens, use a soft sponge or brush to remove it.
Avoid steel wool and harsh abrasive tools, especially if the basket has a non-stick coating.
4. Clean the Inside of the Air Fryer
Now comes the part people often forget.
Use a slightly damp microfiber cloth or soft sponge to wipe the inside walls.
Pay particular attention to areas where grease or crumbs have accumulated.
Don’t pour water into the appliance and don’t submerge the main electrical unit.
Instead, use a small amount of moisture on the cloth and wipe carefully.
5. Don’t Forget the Heating Element
The heating element can collect grease and tiny food particles over time.
With the appliance unplugged and completely cool, inspect the area carefully.
Use a soft, slightly damp cloth to remove accessible residue.
For stubborn particles, a soft brush can help loosen them.
Don’t spray cleaning solution directly onto the heating element or electrical components.
6. Clean the Outside
The outside of your air fryer deserves attention too.
Wipe the control panel, handle, sides, and top with a slightly damp microfiber cloth.
If you’re using dish soap, use only a small amount and don’t allow liquid to enter buttons, vents, or electrical openings.
7. Rinse and Dry the Removable Parts
After washing the basket and tray, rinse them thoroughly to remove soap residue.
Then dry everything completely before putting it back together.
Don’t rush this step.
A completely dry appliance is important for safe operation and helps prevent moisture from lingering where it shouldn’t.
8. Put Everything Back Together
Once all the removable parts are clean and completely dry, reassemble the air fryer.
Before using it again, check that the basket and tray are correctly positioned according to your model’s instructions.
What If Your Air Fryer Still Smells Burnt?
If you’ve cleaned the basket but the smell remains, don’t automatically assume the appliance is broken.
Check for hidden grease or crumbs around the heating area and inside corners.
Also think about what you’ve been cooking.
Foods with a lot of fat can create more residue, while tiny food particles can burn when they’re repeatedly exposed to high temperatures.
If you notice persistent smoke, burning odors from the electrical components, sparks, damaged wiring, or unusual operation, stop using the appliance and follow the manufacturer’s troubleshooting or service instructions.
Can You Use Baking Soda?
Baking soda can be useful for stubborn grease on some removable parts.
Make a paste with a small amount of baking soda and water, apply it to the residue, and gently scrub with a soft sponge.
However, be careful with non-stick coatings. Don’t use aggressive scrubbing simply because a cleaning hack recommends it.
And never mix baking soda with other cleaning chemicals.
What About the Dishwasher?
Some air-fryer baskets and trays are dishwasher-safe, while others aren’t.
Check your specific model’s instructions before putting any component in the dishwasher.
Even when a manufacturer says a part is dishwasher-safe, hand washing may help preserve certain coatings over time.
The main air-fryer unit should never be submerged or placed in a dishwasher.
How Often Should You Clean Your Air Fryer?
You don’t necessarily need to deep-clean the entire appliance after every meal.
A simple routine works well:
After each use:
Remove crumbs and wipe obvious grease from the basket and tray.
Every few uses:
Wash the removable parts thoroughly with warm water and dish soap.
Regularly:
Inspect the interior and heating area for accumulated grease or food particles.
Whenever you notice a burnt smell:
Stop and inspect the appliance rather than simply covering the odor with another cleaning product.
Common Air Fryer Cleaning Mistakes
Using Abrasive Scrubbers
Steel wool and rough scouring pads can damage non-stick surfaces.
Spraying Cleaner Directly Inside
Liquid can reach electrical components or openings where it doesn’t belong.
Apply cleaner to a cloth instead.
Ignoring the Heating Area
Cleaning only the basket won’t help much if grease and crumbs are accumulating above it.
Putting Everything Away While Wet
Allow removable parts to dry completely before reassembling the appliance.
Cleaning Only When There’s a Problem
By the time you notice smoke or a strong burnt smell, residue may already have built up significantly.
A Simple Routine That Keeps Your Air Fryer Fresh
The easiest approach is to clean small amounts of mess before they become big ones.
After cooking, let the appliance cool completely, remove the basket, throw away crumbs, wash the removable parts, and quickly wipe the interior.
It takes a few minutes.
That small habit can save you from dealing with thick, baked-on grease later.
Final Thoughts
A strange burnt smell coming from your air fryer isn’t something you should simply accept.
Grease, crumbs, and food residue can accumulate in places that are easy to overlook, especially around the heating area.
The good news is that regular maintenance doesn’t have to be complicated.
Warm water, dish soap, a soft sponge, and a few minutes of your time are usually enough for routine cleaning.
And once you’ve cleaned your air fryer properly, there’s a good chance your next meal will taste like what you actually cooked—not like last week’s dinner.
