How often to clean an air fryer
The parts that touch food, every time. The parts that catch fat, every time you cook something fatty. Everything else on a schedule set by what you cook rather than by the calendar — and that last part is AirfryerHQ's opinion rather than anybody's instruction, which is why it says so.
Questions this answers
- How often should I clean my air fryer?
- Do I need to clean it after every use?
- How often does the heating element need doing?
Waiting for it to look dirty is the mistake
The parts that matter are the ones you cannot see — the underside of the element, the shield, the floor of the outer pan. By the time there is something visible in the chamber there has been something on the element for a while.
Electrical Safety First identifies accumulated fat and food residue in this appliance class specifically as a fire risk, which is the reason this is a safety page as much as a housekeeping one.
The method, part by part
| Part | What is on it | How often | Dishwasher |
|---|---|---|---|
| Drawer | Greasy film | After every use | Dishwasher safe on the models we hold |
| Splatter guard | Greasy film | After every use | Dishwasher safe on the models we hold |
| Interior of the chamber | Greasy film | After every use | Not removable, so the question does not arise |
Drawer — Greasy film
The drawer and the pan under the basket
In a drawer machine the basket sits inside an outer pan that catches everything that drips. Because nothing is cooked directly in it, it looks clean when it is not, and rendered fat left in it is the single commonest cause of an air fryer that smokes.

What works
Wash the outer pan every time, not just the basket
Hot soapy water and a non-abrasive sponge, or the dishwasher where the manufacturer permits it. Tower's manual permits the pan in the dishwasher alongside the basket.
Published by RKW Ltd (Tower Housewares).Drain fat before moving the drawer
Cosori's manual warns to watch for hot oil collected in the basket and to drain it before replacing the basket, to avoid splashing. On a batch cook, emptying the pan between batches is also what stops the second batch smoking.

What not to do, and why
Pouring hot fat down a sink
It solidifies in the trap and in the drain. Let it cool and put it in the bin, or into a container.
Wiping the pan out and calling it done
A wiped pan retains a film of fat that carbonises at the next cook and smokes. This is the commonest cause of the smoke complaints in the troubleshooting catalogue, and it is a cleaning failure rather than an appliance fault.

Splatter guard — Greasy film
The splatter guard, and why it decides whether the machine smokes
Machines with the element in a hinged lid carry a removable guard between the element and the food. It is the part that catches spattering fat, and it has the most explicit published cleaning instruction of anything in this catalogue — including a deep-clean method involving boiling it.

What works
Clean it after every single use
Ninja's manual is unambiguous: clean the splatter guard after every use, and always ensure it is installed when cooking, because failing to use it results in oil building up on the heating element which can cause smoking.
Published by SharkNinja Europe Limited.Soak it overnight for baked-on grease
The published instruction. After soaking, the supplied cleaning brush is used to remove grease from the stainless steel frame and front tabs.
Published by SharkNinja Europe Limited.Deep clean by boiling it for ten minutes
Ninja publishes this specifically: put the splatter guard in a pan of water and boil it for ten minutes, then rinse with room-temperature water and allow it to dry completely. It is the only boiling instruction in any manual read for this catalogue.
Published by SharkNinja Europe Limited.
What not to do, and why
Running the appliance without it fitted
Not a cleaning shortcut but a fire and smoke issue: the manual states directly that failure to use the splatter guard results in oil buildup on the heating element, which can cause smoking.
Published by SharkNinja Europe Limited.Abrasive tools or cleaners on the guard
Prohibited for every part of this appliance by the same manual.

- Your own manual is the governing document. Where it differs from anything here, follow it — this is a synthesis of what several manufacturers publish, not an instruction for your specific machine.
- Only one appliance in this catalogue has a splatter guard. If yours has a removable shield under the element, the same reasoning applies and the specific instruction is this manufacturer's.
Interior of the chamber — Greasy film
How often an air fryer actually needs cleaning
Only one interval in this catalogue is published by a manufacturer, and it is the strictest one: clean the splatter guard after every use. The rest is a judgement based on where fat accumulates, and it is stated as a judgement.
- How often
- After every use
- Dishwasher
- Not removable, so the question does not arise
Before you touch it
Unplug the appliance at the wall and let it cool completely before cleaning any part of it. An air fryer draws 1.5-2kW and its element and chamber stay dangerously hot for a long time after the fan stops — one manual in this catalogue warns that the frying tray is still hot half an hour after use. Never immerse the main unit, the cord or the plug in water or any other liquid. Every manual read for this catalogue says so, and it is the single instruction with no exceptions anywhere in the set.
What works
Every use: the basket, the crisper plate, the pan under it, and any shield
The basket and plate because they touch food; the pan because it holds the fat; the shield because its manufacturer says so in as many words and links not doing it to oil on the element.
Published by SharkNinja Europe Limited.Every use after anything fatty, whatever else you do
Bacon, sausages, chicken thighs and lamb all leave enough rendered fat to smoke at the next cook. This is the interval that actually prevents the commonest complaint in the troubleshooting catalogue.
Published by Electrical Safety First.Weekly to monthly: the chamber, the element area and the vents
No manufacturer publishes an interval for these. This is AirfryerHQ's judgement based on how quickly a film builds up, and it is labelled as such rather than presented as an instruction.
What not to do, and why
Leaving fat in the pan between cooks because the food was not messy
Fat that has been heated once is easier to ignite the second time, and Electrical Safety First identifies accumulated fat and food residue as a fire risk in this appliance class specifically.
Published by Electrical Safety First.Waiting for it to look dirty
The parts that matter are the ones you cannot see: the underside of the element, the shield, the pan floor. By the time there is something visible in the chamber there has been something on the element for a while.
- Your own manual is the governing document. Where it differs from anything here, follow it — this is a synthesis of what several manufacturers publish, not an instruction for your specific machine.
- Only the after-every-use interval is published by a manufacturer. The weekly and monthly intervals are AirfryerHQ's judgement.
Evidence and confidence
- Applies to
- Specific to this type of appliance
- Why this rating
- One published interval and one authoritative statement about why fat accumulation matters. The weekly and monthly intervals are explicitly AirfryerHQ's judgement, and separating the two is the point — a page presenting all four in the same voice would be claiming more than it has.
