how do i clean the heating element in my gowise usa air fryer? it looks gunky.

Diagnosis

The "gunk" accumulating on the heating element of your GoWISE USA GW22956 is typically a combination of aerosolized fats, oils, and microscopic food particles. Because the 7-quart model uses a powerful convection fan to circulate hot air, grease from your food is blasted upward into the heating coil. Over time, this grease undergoes a process called polymerization, where it hardens into a sticky, brown, or black resin that is resistant to simple wiping. This buildup is more than just a cosmetic issue; it can cause the air fryer to emit a burning smell or produce smoke during high-temperature cycles. If the residue becomes thick enough, it can create "hot spots" on the element, leading to uneven cooking or, in extreme cases, causing the element to overheat and burn out prematurely. You can confirm the severity by checking if the residue is tacky to the touch or if you see small carbonized flakes peeling off the coil.

How to Fix It

To clean the heating element without damaging the protective coating or risking an electrical short, follow these precise steps:

1. Complete Power Down: Unplug the GW22956 from the wall outlet. Wait at least 45 minutes to ensure the element has cooled to room temperature. Attempting to clean a warm element can cause chemical cleaners to vaporize or burn onto the surface.
2. Positioning: Place the air fryer on a stable surface. Remove the frying basket and crisper tray entirely to provide a clear line of sight to the top of the internal chamber.
3. Dry Debris Removal: Use a soft-bristled nylon brush or a clean, dry toothbrush to gently scrub away loose crumbs or carbonized flakes. Avoid using steel wool or metal scrapers, as these will scratch the heating element and lead to rapid oxidation.
4. Degreasing Treatment: Dampen a microfiber cloth or a cotton swab with a small amount of isopropyl alcohol (70% concentration) or a mild grease-cutting dish soap diluted in water. The cloth should be damp, not dripping.
5. Targeted Scrubbing: Carefully wipe the heating element, working from the top down. Apply light pressure to lift the polymerized oil. If a spot is particularly stubborn, hold the damp cloth against the gunk for 30 seconds to soften it before wiping.
6. Rinse and Dry: Use a second cloth dampened with plain water to wipe away any remaining soap or alcohol residue. This is critical; any leftover cleaning agent will smoke the next time you turn on the machine.
7. Air Cure: Leave the basket out and let the unit air dry for 20 minutes before plugging it back in.

If That Didn't Work

• The Paste Method: Create a thick paste using baking soda and a few drops of water. Apply a small amount of the paste to the most stubborn brown spots on the element using a cotton swab. Let it sit for 15 minutes, then gently scrub with a soft brush and wipe clean with a damp cloth. This provides a mild abrasive action that breaks down carbonized grease without scratching the metal.
• Deep Steam Cleaning: If the gunk is inside the crevices of the heating assembly, fill the air fryer basket halfway with water and a squeeze of lemon juice. Run the air fryer at 400°F for 5 minutes. The resulting steam will loosen the grease on the heating element. Once finished, unplug the unit and wipe the element while it is still warm (but not hot) using a microfiber cloth.
• Professional Degreaser: For extreme buildup, use a dedicated kitchen degreaser spray on a cloth (never spray directly into the machine). Apply the degreaser to the cloth, wipe the element, and then immediately follow with a water-dampened cloth to ensure no chemical residue remains, as these cleaners can be toxic if heated.

Heads Up

• Avoid Direct Liquid Contact: Never pour water or spray cleaning liquids directly into the top of the air fryer. Liquid can seep into the fan motor or the electrical housing, causing a permanent short circuit.
• Preventative Maintenance: To reduce future buildup, avoid using aerosol cooking sprays (like Pam) directly in the basket, as these contain lecithin which creates a stickier residue on the heating element than pure olive or avocado oil.
• Post-Cooking Cool Down: After a heavy grease session (like wings), run the air fryer for 2 minutes at a low temperature with the basket empty to help "bake off" residual oils before they polymerize.
• Basket Cleanliness: Ensure your crisper tray is thoroughly degreased; leftover oil in the tray is the primary source of the smoke and gunk that eventually migrates to the heating element.
