How to Clean an Air Fryer in 6 Simple Steps

If you’ve ever wondered how to clean an air fryer properly, you’re probably staring at a basket with a tacky layer of grease that no amount of quick rinsing fixes. Maybe your Ninja or Cosori has started puffing out a faint smoke smell when it preheats, or your fries don’t come out as crisp as they did on day one. That buildup isn’t just ugly. It’s the reason your air fryer is slowly cooking worse.

The good news: cleaning an air fryer the right way takes about 15 minutes, needs nothing fancier than dish soap and baking soda, and follows a simple 6-step method. Here’s exactly how to do it.

Why Your Air Fryer Smells Like Burnt Grease

An air fryer is basically a small, powerful convection oven. A fan blasts hot air around your food, and that same fan throws tiny droplets of grease onto everything inside the unit: the walls, the fan cover, and the heating element on top.

Over time, that grease bakes into a brown, varnish-like film. When you preheat, old grease hits its smoke point and you get that acrid smell. Worse, the film insulates the heating element, so the unit takes longer to get hot and food comes out less crisp. Both Ninja and Cosori manuals warn that this kind of buildup causes smoking. This isn’t cosmetic maintenance. It’s what keeps the machine cooking the way it did out of the box.

What You Need to Clean an Air Fryer

Grab these before you start:

• Mild dish soap (Dawn or similar)
• A non-abrasive sponge or Scrub Daddy
• A soft-bristle brush or an old toothbrush for corners
• Baking soda
• Microfiber cloths or paper towels
• A wooden skewer or cotton swabs for tight spots around the element
• Half a lemon (optional, for the steam trick later)

What NOT to grab: oven cleaner, bleach, metal scrubbers, and anything abrasive. Oven cleaner strips the non-stick coating and leaves toxic residue that heats up with your next batch of wings. Steel wool scores the coating and can void your warranty.

How to Clean an Air Fryer: The 6-Step Method

Step 1: Unplug and Let It Cool Down

Always unplug first, then give the unit at least 30 minutes to cool completely. Washing a hot basket under cold water causes thermal shock, which can warp the non-stick coating or the metal underneath. If the basket is still warm to the touch, wait longer. Patience here saves you from flaking coating later.

Step 2: Wash the Basket and Drawer

Pull out the basket and drawer (or tray, depending on your model) and wash them in warm, soapy water with your non-abrasive sponge. For greasy buildup, let the parts soak for 10 minutes before scrubbing. Use the soft brush on the perforations and corners where crumbs collect.

Some baskets, including many from Ninja and Cosori, are labeled top-rack dishwasher safe. The dishwasher will clean them, but the harsh detergent wears down non-stick coatings faster. Hand washing takes five minutes and adds months to the coating’s life. Your call, but the gentler route pays off.

Step 3: Tackle Stuck-On Grease With a Baking Soda Paste

For that tacky brown film that survives the sponge, mix baking soda with a little water into a thick paste. Spread it over the greasy spots, wait 20 minutes, then scrub gently with the soft brush. The mild abrasion lifts carbonized grease without scratching the coating. For most buildup, the baking soda paste plus patience gets the job done.

Step 4: Wipe Down the Interior

Dampen a microfiber cloth with warm, soapy water, wring it out well, and wipe the cooking chamber walls and base. You’re wiping, not flooding. No liquid should pool anywhere near the electronics.

Use the toothbrush or wooden skewer for the seams and the vent slots where crumbs hide. Crumbs left in the basket don’t just burn on the next cook, they also attract kitchen pests. If flies are circling your kitchen, here’s how to get rid of fruit flies before they settle in.

Step 5: Clean the Heating Element (The Step Everyone Skips)

This is the part that separates a quick wipe from a real cleaning. Unplug confirmed, flip the unit upside down on a towel, and look at the heating element and fan area on the underside of the top.

Take a barely-damp cloth or sponge and gently wipe the element and the fan cover. For the tight ring around the element, wrap a cotton swab in a damp cloth and work it around slowly. Never spray cleaner directly at the element, and never submerge this part in water. If the buildup is thick, press a baking-soda-paste cloth against it for a few minutes first, then wipe.

Step 6: Wipe the Exterior and Reassemble

Wipe the outside of the unit with a damp cloth and dry everything immediately. Make sure the basket, drawer, and interior are bone dry before you slide them back in. Reassemble, then run the empty air fryer at 400°F for about 5 minutes. This burns off any faint soap residue and confirms everything heats evenly.

The Lemon Steam Trick for Lingering Smells

If your air fryer still smells like last month’s salmon after a full clean, try this. Put a few lemon slices in the drawer with about an inch of water and run it at 350°F for 3 minutes. The steam loosens odor-causing residue and the citrus neutralizes the smell. Wipe everything down once it cools, the same way you’d deodorize your coffee grinder.

4 Mistakes That Ruin an Air Fryer

1. Submerging the main unit. The motor, fan, and electronics live in the base. One dunk in the sink and the air fryer is done. Removable parts get water. The base only gets a damp cloth.

2. Using oven cleaner or bleach. These are far too aggressive for non-stick coatings and leave residues that are toxic when heated. If a product says “oven cleaner,” keep it away from your air fryer.

3. Attacking grease with metal scrubbers. Wire brushes and scouring pads carve grooves into the coating. Food sticks to the grooves, you scrub harder, and the cycle continues until the coating flakes into your food.

4. Skipping the heating element. The basket looks clean, the exterior shines, but the element is still varnished with grease. That hidden buildup is what causes smoke and weak heating. Step 5 takes two minutes. Don’t skip it.

One more note on smells: a clean air fryer won’t fix odors coming from your sink drain. If the funk is coming from below the counter, here’s how to clean a garbage disposal so the whole kitchen smells right again.

How Often Should You Clean Your Air Fryer?

A simple routine keeps the deep cleans rare:

• After every use: Empty crumbs, wipe the basket and drawer with a soapy sponge.
• Weekly: Wash the removable parts thoroughly, wipe the interior, check the element area.
• Monthly: Do the full 6-step method above, including the heating element.

Appliances only stay low-maintenance if you keep a routine. Daily wiping is what makes the weekly wash easy, and the weekly wash is what keeps the monthly deep clean from becoming a rescue mission.

Frequently Asked Questions

Can I put my air fryer basket in the dishwasher?

Many baskets from Ninja, Cosori, and Philips are labeled top-rack dishwasher safe, so it won’t damage the machine. But dishwasher detergent is harsher than hand soap and wears down the non-stick coating faster. Hand washing takes only a few minutes and is gentler.

Can I use oven cleaner in an air fryer?

No. Oven cleaner is far too aggressive for non-stick coatings and leaves behind residue that becomes toxic when heated. Stick with dish soap and a baking soda paste for stubborn spots.

Why does my air fryer smoke when it preheats?

Almost always, it’s baked-on grease. Old oil on the heating element or interior walls hits its smoke point as the unit heats up. Do the full 6-step clean above, paying special attention to Step 5 (the heating element).

Do I need special air fryer cleaning products?

No. Dish soap, baking soda, a soft sponge, and microfiber cloths handle everything. Save your money for parchment liners, which make future cleanups easier.

Conclusion

Learning how to clean an air fryer comes down to a simple habit: wipe the basket after every use, wash the parts weekly, and give the whole unit, heating element included, a proper deep clean once a month. The whole process takes about 15 minutes and only needs dish soap, baking soda, and a soft cloth.

Your reward is an air fryer that heats fast, smells like nothing, and keeps turning out crisp food instead of soggy, smoke-flavored disappointments. Fifteen minutes of maintenance beats replacing a $100 machine every couple of years.
