Pull out the basket after a few weeks of regular use and you’ll probably notice a dark, sticky film clinging to the bottom and sides, sometimes almost like a light varnish. That’s not leftover food, it’s oil that’s been baked on repeatedly by the hot air circulating inside, layer after layer, until it turns tacky and dark.
Most air fryer baskets have a non-stick coating, which means the usual scrub-hard approach can do more harm than good here. This guide covers a quick everyday method, and a deeper approach for grease that’s had time to really set in.
At a Glance: Which Method Do You Need?
- Light grease after regular use? A quick soak and wipe handles it. Head to Method 1.
- Sticky, baked-on buildup that’s been there a while? A baking soda soak works through it. Head to Method 2.
Not sure which one you need? Start with Method 1, it only takes a few minutes and covers most everyday cleanups.

Method 1: Quick Soak and Wipe (For Everyday Grease)
This is the routine to get into after every use. It takes just a few minutes and keeps grease from ever getting the chance to bake on properly.
What You’ll Need
- Warm water
- Dish soap
- A soft sponge or non-abrasive cloth
- A soft-bristle brush, for corners and the mesh holes
- A towel for drying
Don’t have a soft sponge that’s safe for non stick surfaces? This non stick safe scrub sponge works well here.
How to do it:
Step One: Let the basket cool completely before cleaning, at least 30 minutes. Running water over a hot basket can warp or crack the coating, so don’t rush this part.
Step Two: Remove the basket and crisper plate, then pour out any pooled oil before you start.
Step Three: Fill the sink or a basin with warm water and a few drops of dish soap, then let the parts soak for about 10 minutes.
Step Four: Wipe down with a soft sponge, using a soft-bristle brush to get into corners and the perforated holes where crumbs tend to collect.
Step Five: Rinse thoroughly until the surface no longer feels tacky, then dry completely with a towel before putting everything back.
Method 2: Baking Soda Soak (For Baked-On Buildup)
Use this when grease has clearly been sitting for a while and a quick soap-and-water wash isn’t cutting through it. The extra time and mild abrasion of baking soda lift residue that’s already hardened, without needing anything rough on the coating.
What You’ll Need
- Baking soda
- Warm water
- Dish soap
- A soft sponge or non-abrasive cloth
- A towel for drying
If your basket has stubborn, dark residue in the corners, a soft bristle brush like this helps work the paste into those tight spots without needing anything abrasive.
How to do it:
Step One: Let the basket cool completely, then remove it along with the crisper plate.
Step Two: Mix baking soda with a small amount of water to form a thick paste, roughly 3 parts baking soda to 1 part water.
Step Three: Spread the paste over the greasy areas, focusing on the spots that feel sticky or look darkest.
Step Four: Let it sit for 15 to 20 minutes. This gives the baking soda time to soften the baked-on residue.
Step Five: Wipe away the paste with a soft sponge, using a little more pressure on stubborn spots, still no scrubbing pads or anything abrasive.
Step Six: Rinse thoroughly under warm water, then dry completely with a towel before reassembling.
If the Basket Is Clean but Your Air Fryer Still Smokes
Sometimes the basket isn’t the problem. Grease can collect inside the main unit, especially around the heating element, and that residue burns every time you cook. With the unit unplugged and fully cooled, wipe the interior with a barely damp cloth, and never pour water directly into the base or spray anything near the fan or heating element. If the smoke smells electrical or you notice sparking, stop using the unit and contact the manufacturer.
A Quick Habit That Helps a Lot
A quick rinse right after the basket cools, rather than leaving it until your next cook, is what actually keeps buildup from forming in the first place. Most of the grease people struggle with isn’t from one bad cook, it’s weeks of oil that never got wiped away in time.
Whichever method you use, the pattern stays the same, soak, wipe gently, then dry completely. Stay consistent with cleaning after each use, and you’ll rarely need the deeper method at all.
