Clean your air fryer after every single use, even if the basket looks spotless. That means washing the basket and tray with warm soapy water once the unit has cooled, plus a deeper clean of the heating element area about once a week if you cook daily. How often should you clean an air fryer in practice depends on how much you use it and what you cook, but the post-cooking wipe is the baseline that stops grease from ever building up.
If you use your air fryer daily, a quick wash after every meal is non-negotiable. Leftover oil and food particles bake onto the basket during the next cook, turning a two minute rinse into a twenty minute scrub.
If you only air fry a few times a month, you can still clean after each use, but the deep cleaning schedule stretches out. The key is matching your routine to how fast grease actually accumulates in your machine.
What You Cook Changes the Cleaning Schedule
Fatty foods like bacon, chicken thighs, and marinated meats splatter oil onto the basket and the heating element. After those cooks, you may need to wipe the interior right away, not just wash the basket.
Dry foods like frozen fries, roasted vegetables, and breaded items leave mostly crumbs and light residue. Those still need a basket wash, but the deep clean can wait a little longer.
Signs Your Air Fryer Needs Cleaning Right Now
Smoke drifting out during cooking is the most obvious warning sign. It usually means oil and food residue on the heating element are burning off at high temperature.
A stale or oily smell, food that sticks more than usual, and visible grease in the basket all point the same way. When you notice any of these, clean the air fryer before your next cook, not after.
Quick Cleaning vs Deep Cleaning: Two Different Schedules
A quick clean is the basket and tray wash you do after each use. A deep clean is the weekly or biweekly job that includes wiping the heating element, checking the crumb tray, and cleaning the exterior.
Some models also have a small filter that collects grease and odors. Check your manual for how often that filter needs attention, since it is easy to forget and hard to notice when it is clogged. A clogged filter can also make the air fryer louder and less efficient.
What Happens If You Skip Cleaning Too Long
Old grease does more than look unappealing. It smokes during cooking, gives food a stale flavor, and restricts airflow, which makes your food cook unevenly.
In extreme cases, heavy grease buildup near the heating element is a fire risk. Cleaning regularly also protects the nonstick coating, since baked-on residue gets harder to remove the longer it sits. A few minutes of prevention saves you from a much longer scrubbing session later.
How to Build a Cleaning Routine That Sticks
- Wash the basket and tray with warm soapy water after every use once the unit has cooled.
- Do a weekly deep clean of the heating element and interior if you cook daily.
- Clean right after cooking fatty or heavily marinated foods, not later.
- Use parchment liners to reduce residue, but never cover the whole basket and block airflow.
- Treat smoke or a strong smell as a signal to clean sooner, not as normal behavior.
If your air fryer is older and the buildup has become impossible to remove, you may be weighing whether to keep cleaning it or replace it. The air fryer guides on this site can help you compare your options before you make that call.

Frequently Asked Questions
Can you put an air fryer basket in the dishwasher?
Most baskets and trays are dishwasher safe, but check your manual first. The nonstick coating can wear down faster in a dishwasher, so hand washing with warm soapy water is gentler and usually enough for daily cleaning. If you do use the dishwasher, place the basket on the top rack.
How do you clean a burnt air fryer basket?
Fill the basket with warm water and a few drops of dish soap, then let it soak for 15 to 20 minutes. Scrub with a soft sponge or nylon brush afterward. Avoid steel wool and abrasive pads, which scratch the nonstick coating and make future cleaning harder.
Do you need to clean the heating element in an air fryer?
Yes, but less often than the basket. Wipe the heating element and the surrounding interior gently with a damp cloth every few weeks, depending on how much you cook. Make sure the air fryer is unplugged and completely cool before you touch that area.
Is it safe to use an air fryer with old grease buildup?
It is not a good idea. Old grease can smoke, give food a stale taste, and reduce airflow, which makes cooking less even. In extreme cases, built-up grease near the heating element is a fire risk, so clean it as soon as you notice smoke or a strong oily smell.
The short answer is that a quick clean after every use and a deeper clean once a week keeps most air fryers safe and working well. Stick to that routine and your air fryer will cook more evenly, smell fresher, and last longer.
