The fastest way to remove grease buildup

Grease collects in your air fryer basket, tray, and heating chamber because hot air circulates around food but cannot carry away all the oil that drips. The fastest removal method is to wipe the basket and tray with a damp cloth or paper towel while the unit is still warm (but unplugged and cool enough to touch), because grease stays soft and lifts easily before it hardens.

For stubborn buildup that has already dried, soak the removable parts in hot soapy water for 10 to 15 minutes, then scrub with a soft brush or non-abrasive sponge. Most air fryer baskets and trays are dishwasher-safe — check your manual — which saves time if you run a load anyway. Never use steel wool or harsh scouring pads, as these scratch the non-stick coating and create places where grease and food particles collect.

Key Takeaways

  • Wipe the basket and tray with a damp cloth when ready after cooking while grease is still warm and soft, before it hardens and sticks.
  • Soak stubborn dried grease in hot soapy water for 10 to 15 minutes, then scrub gently with a soft brush or non-abrasive sponge.
  • Most air fryer baskets and trays are dishwasher-safe, but verify in your manual before placing them in the machine.
  • Avoid steel wool and harsh scrubbers that damage the non-stick surface and create rough spots where grease accumulates.
  • Clean the heating chamber and exterior vents with a dry cloth or soft brush to prevent grease from building up inside the unit.

Cleaning the basket and tray after each use

The basket and tray are where most visible grease collects, and cleaning them right after cooking takes less than two minutes. Unplug the air fryer and let it cool for three to five minutes until the exterior is safe to touch. Remove the basket and tray, then wipe both sides of each piece with a damp cloth or damp paper towel to lift the warm grease.

If grease has already dried and stuck, fill your sink with hot water and a squirt of dish soap, then place the basket and tray in the water. Let them soak for 10 to 15 minutes so the grease softens. Use a soft sponge or soft-bristled brush to scrub away the grease, paying attention to the corners and mesh where particles hide. Rinse under running water and dry with a cloth or let them air-dry before putting them back in the unit.

Dishwasher cleaning for basket and tray

Most modern air fryer baskets and trays are dishwasher-safe on the top rack, which means you can run them through a regular cycle without damage. Check your air fryer manual first, because some older models or specialty coatings are not dishwasher-safe. If your manual says yes, place the basket and tray on the top rack of your dishwasher, run a normal hot-water cycle, and they come out grease-free without hand scrubbing.

Dishwasher cleaning works best if you rinse off loose food and grease first with a damp cloth, because heavy buildup can leave residue even after a full cycle. If you notice grease spots after the cycle finishes, the basket or tray may have a damaged non-stick coating — in that case, hand-wash instead and consider replacement if the damage spreads.

Cleaning the heating chamber and vents

Grease can travel beyond the basket and tray into the heating chamber and air vents, where it reduces airflow and can create smoke or burnt smells. To clean these areas, unplug the unit and let it cool completely. Use a dry cloth or soft-bristled brush to wipe the interior walls and the heating element area, brushing away any grease or food particles you can reach.

For the exterior vents and air intake, use a dry cloth or a soft brush to clear dust and grease buildup. Do not use water inside the heating chamber or near electrical components. If grease has built up heavily inside the unit, you may need to tilt the air fryer slightly and use a small brush or old toothbrush to reach corners. Never insert anything into the heating element itself.

Preventing heavy grease buildup

The best way to reduce grease cleaning is to prevent heavy buildup in the first place. Pat food dry with a paper towel before placing it in the basket, because excess surface moisture turns to steam and carries more oil into the air. Use a light coating of oil or cooking spray rather than heavy oil, and avoid foods that release large amounts of fat, like fatty cuts of meat or very oily prepared foods.

Line the tray (not the basket, which needs airflow) with aluminum foil or parchment paper designed for air fryers to catch dripping grease. This catches most of the oil before it touches the tray, and you can straightforward throw away the foil or paper after cooking. Replace the liner every few uses or when it becomes heavily soiled. This method cuts cleaning time dramatically and keeps grease from baking onto the tray surface.

What to avoid when cleaning

Never use steel wool, scouring pads, or abrasive cleaners on the basket or tray, because these scratch the non-stick coating. Once the coating is damaged, grease sticks more easily and becomes harder to clean. Do not soak the entire air fryer unit or submerge it in water — only the removable basket and tray should contact water. Never use harsh chemical cleaners or oven cleaner inside the unit, as these can damage the heating element and leave toxic residue.

Avoid spraying water directly into the heating chamber or electrical components. If you need to clean the interior, use a dry cloth or brush only. Do not attempt to clean the heating element itself — it is designed to shed grease naturally as it heats, and scrubbing it can damage the element or create a fire hazard.

How often to deep clean your air fryer

A quick wipe after each use keeps your air fryer in good working order, but a deeper cleaning every two to four weeks prevents grease from hardening inside the unit. During a deep clean, remove the basket and tray and soak them in hot soapy water for 15 to 20 minutes, then scrub thoroughly with a soft brush. Wipe the interior walls and heating chamber with a damp cloth, then dry everything completely before reassembling.

If you notice smoke, a burnt smell, or slower cooking performance, grease buildup is likely the cause and a deep clean is overdue. After cleaning, run the air fryer empty at 400°F for five minutes to dry any moisture inside before cooking food again. This prevents rust and ensures the heating element works at full power.

Frequently Asked Questions

Can I use vinegar or baking soda to clean my air fryer?

Yes. Mix baking soda with a little water to form a paste and scrub the basket or tray, then rinse thoroughly. White vinegar can be sprayed on grease stains and wiped away with a cloth. Both are safe for non-stick surfaces and leave no chemical residue. Avoid vinegar inside the heating chamber or near electrical parts — use it only on removable parts.

Is it safe to put the air fryer basket in the dishwasher?

Most modern baskets are dishwasher-safe on the top rack, but check your manual first because some models are not. If your manual says yes, place it on the top rack and run a normal cycle. If you are unsure, hand-wash instead to avoid damaging the non-stick coating.

Why does my air fryer smell burnt after cleaning?

Burnt smell after cleaning usually means water or cleaning residue is still inside the heating chamber. Make sure the basket and tray are completely dry before putting them back in, and run the unit empty at 400°F for five minutes to evaporate any remaining moisture. If the smell persists, grease may be burning on the heating element — do a deep clean of the interior.

Can I use cooking spray to prevent grease buildup?

Cooking spray can leave residue that builds up over time, especially if you use it every day. Pat food dry and use a light brush of oil instead, or line the tray with parchment paper to catch dripping grease. If you do use spray, clean the basket more often to prevent sticky buildup.

What should I do if grease has hardened inside the heating chamber?

Let the unit cool completely, then use a dry cloth or soft brush to gently scrape away dried grease from the interior walls. Do not use water or liquid cleaners inside the chamber. If grease is stuck to the heating element itself, run the unit empty at 400°F for 10 minutes to soften it, then brush gently. If buildup is severe, contact the manufacturer for guidance.
