The safest way to clean the heating element

The heating element is the coil or strip at the top of your air fryer that reaches extremely high temperatures. You can clean it, but you must unplug the unit first and let it cool completely—this takes at least 30 minutes after the last use. Never spray water directly on the element or soak it. Instead, use a soft brush, a dry cloth, or a slightly damp cloth to wipe away loose debris and buildup.

Most buildup on the heating element is grease or food particles that have splashed upward during cooking. These burn onto the surface and can reduce heat efficiency or create smoke. The good news is that gentle, dry cleaning removes most of it without risk of damage. If you see heavy, stuck-on residue, a slightly damp (not wet) cloth works better than a dry one, but always wring out excess water first.

Do not use abrasive scrubbers, steel wool, or harsh chemicals on the element itself. These can scratch the surface or damage the protective coating. Avoid commercial oven cleaners entirely—they can corrode the metal or leave toxic residue that heats up during cooking.

Key Takeaways

  • Always unplug the air fryer and wait at least 30 minutes for the heating element to cool before touching it.
  • Use only a soft brush or slightly damp cloth to wipe the element; never spray water directly on it or soak it.
  • Grease and food particles burn onto the element during cooking and reduce efficiency, so regular gentle cleaning keeps it working well.
  • Avoid abrasive scrubbers, steel wool, and commercial cleaners, which can scratch or corrode the element.
  • If buildup is extremely heavy and won't come off with a damp cloth, the element may need professional replacement rather than aggressive scrubbing.

When to clean the heating element

You do not need to clean the heating element after every use. Instead, clean it when you notice visible buildup—usually every 10 to 20 uses, depending on how often you cook fatty foods like bacon, sausage, or breaded items. These foods splatter more and leave more residue on the element.

A sign that cleaning is overdue is smoke during cooking, even when the basket is clean and the food is not burning. Another sign is uneven browning or longer cooking times than usual. Both suggest the element is partially blocked by grease or carbon buildup and cannot transfer heat as efficiently.

Step-by-step cleaning process

Step 1: Unplug and cool. Turn off the air fryer and unplug it from the wall outlet. Do not rely on the power button alone. Wait at least 30 minutes, or until the unit is cool enough to touch the basket without discomfort.

Step 2: Remove loose debris. Use a soft-bristled brush (an old toothbrush works well) to gently brush away loose crumbs, ash, or flaked-off particles from the element. Brush downward so debris falls into the basket or onto a paper towel below, not into the air fryer's body.

Step 3: Wipe with a damp cloth. Dampen a soft cloth with water—wring it out thoroughly so it is barely wet, not dripping. Gently wipe the element surface. If the cloth touches the element, make sure your other hand is not touching any metal part of the fryer to avoid a shock hazard, even though the unit is unplugged.

Step 4: Dry completely. Use a dry cloth to wipe away any remaining moisture. Let the fryer sit open for a few minutes to air-dry before plugging it back in. This prevents any water from dripping onto electrical components.

What not to do

Do not use a pressure washer, spray bottle, or any method that forces water into the heating element or the air fryer's interior. Water inside the unit can damage the motor, thermostat, or electrical wiring and create a fire or shock hazard.

Do not use vinegar, baking soda, or commercial degreasers on the element itself. These can leave residue that burns off during cooking and affects food taste, or they can corrode the metal. Vinegar is sometimes recommended for cleaning the basket or tray, but keep it away from the heating element.

Do not scrape the element with a knife, fork, or any sharp tool. Even small scratches can weaken the metal or expose internal wiring. Do not use a wire brush or steel wool for the same reason.

When to call a professional or replace the element

If the heating element has visible cracks, holes, or areas where the metal is peeling or flaking, it needs replacement. These are signs of age or damage that cleaning cannot fix. A damaged element can malfunction, heat unevenly, or pose a safety risk.

If buildup is so heavy that a damp cloth does not remove it after gentle wiping, and you see no cracks or damage, the element may be nearing the end of its life. At this point, replacement is usually more practical than continued cleaning. Most air fryer manufacturers sell replacement heating elements, and installation typically requires removing a few screws and unplugging a connector—a task many people can do at home, though some prefer to have a technician handle it.

If the air fryer stops heating evenly or stops heating altogether after cleaning, unplug it when ready and do not use it. The element may have been damaged during cleaning, or water may have entered the electrical housing. Contact the manufacturer or a repair service before using the unit again.

Preventing heavy buildup

The less grease that splatters, the less buildup accumulates on the heating element. Pat foods dry before placing them in the basket—moisture turns to steam and carries grease upward. Avoid cooking very fatty cuts of meat directly in the basket without a tray or liner underneath to catch drippings.

Empty the basket and wipe it clean after each use. Leftover grease in the basket can smoke and splatter during the next cook, sending more residue to the element. If you use parchment paper or a silicone mat in the basket, make sure it does not cover the air vents, which would block airflow and cause uneven heating.

Frequently Asked Questions

Can I use a damp cloth on the heating element, or will it damage it?

A slightly damp cloth is safe if you wring it out thoroughly first. The element itself is designed to withstand high heat and brief contact with moisture. The danger is water dripping into the air fryer's interior electrical components, not the element surface. Always dry the element with a clean cloth afterward and let the unit air-dry before plugging it in.

Why does my air fryer smoke even after I clean the heating element?

Smoke usually comes from grease in the basket or tray, not the element. After cleaning the element, also empty and wipe the basket and any drip tray. If smoke continues, check that you are not cooking food that is too wet or fatty for the air fryer. If the element itself is cracked or damaged, it may also cause smoking—in that case, the element needs replacement.

How often should I clean the heating element?

Clean it when you see visible buildup, which is typically every 10 to 20 uses depending on what you cook. Fatty foods like bacon or sausage cause faster buildup than lean meats or vegetables. If you cook mostly dry foods, you may only need to clean it once a month or less.

Is it safe to use vinegar to clean the heating element?

No. Vinegar can leave acidic residue on the element that burns during cooking and affects food taste. It can also corrode the metal over time. Use only water and a soft cloth. Vinegar is safe for cleaning the basket or tray, but keep it away from the heating element and the air fryer's interior.

What should I do if I accidentally got water inside the air fryer while cleaning?

Unplug the unit when ready and do not use it. Leave it unplugged and open for at least 24 hours to air-dry completely. If water entered the motor housing or electrical compartment, contact the manufacturer before plugging it back in. Using a wet air fryer can cause electrical damage or a fire hazard.
