Clean your Ninja Foodi right after it cools, while grease is still soft

The fastest way to clean a Ninja Foodi air fryer is to wipe the basket and tray while they're still warm—not hot enough to burn you, but warm enough that oil hasn't hardened. Most food residue comes off with a damp cloth or soft sponge in under five minutes. If you wait until everything is cold and stuck, you'll spend twice as long scrubbing.

The Ninja Foodi has two removable parts that collect grease and crumbs: the air fryer basket (the perforated metal cage where food sits) and the crisper plate (the flat tray underneath that catches drippings). Both go into the dishwasher on the top rack, or you can hand-wash them. The main unit itself—the heating element and interior walls—never goes in water. You'll clean that separately with a cloth.

Key Takeaways

  • Remove the basket and crisper plate while the unit is still warm and wipe them with a damp cloth before grease hardens.
  • Both the basket and crisper plate are dishwasher-safe on the top rack, or hand-wash them with warm soapy water and a soft sponge.
  • The main unit's interior walls and heating element are cleaned with a damp cloth only—never submerge the machine or spray water inside.
  • Stuck-on food comes off faster with a paste of baking soda and water applied for a few minutes before wiping.
  • Let all parts dry completely before reassembling to prevent moisture from damaging the heating element.

Unplug and let the unit cool for 30 minutes before touching anything

Always unplug the Ninja Foodi and wait at least 30 minutes before you start cleaning. The heating element stays hot long after you turn it off, and touching it can burn your skin. You can start wiping the exterior while you wait, but leave the basket and crisper plate inside until the unit is cool enough to handle comfortably.

If you're in a hurry, you can begin cleaning the removable parts after 15 to 20 minutes if they're cool to the touch on the outside. Test the basket handle first—if you can hold it for three seconds without discomfort, it's safe to remove.

Remove and rinse the basket and crisper plate

Once the unit has cooled, grip the basket handle and pull it straight out toward you. It should slide out easily. Next, lift out the crisper plate—it sits on a ledge below the basket and comes out with a gentle tug. Both parts are now ready to clean.

Rinse both pieces under warm running water to loosen loose crumbs and grease. Use your fingers or a soft brush to brush away any stuck-on food. If food is still soft, a damp cloth will wipe it away in seconds. For stubborn, hardened spots, soak the basket and plate in warm soapy water for five to ten minutes, then scrub with a soft sponge or non-abrasive brush. Never use steel wool or harsh scouring pads—they scratch the non-stick coating.

If you have baked-on grease or food that won't come off, make a paste with baking soda and a little water, spread it on the stuck spot, let it sit for three to five minutes, then scrub gently with a soft sponge. Rinse thoroughly and dry with a clean cloth.

Wipe down the interior walls and heating element

With the basket and crisper plate removed, you can now see inside the main chamber. Use a damp cloth—not dripping wet, just damp—to wipe the interior walls, the bottom, and around the heating element coils at the top. Wipe gently and avoid pressing hard on the heating element itself.

If grease has splattered on the walls, a damp cloth usually removes it. For stubborn spots, dampen the cloth slightly more and let it sit on the spot for a minute before wiping. Never spray water directly into the unit, and never submerge any part of the main machine in water. Water inside the heating chamber can damage the electrical components.

Pay special attention to the corners where the basket normally sits—crumbs and grease collect there. A slightly damp cloth folded into a point can reach into these corners easily.

Clean the exterior and vents

Wipe the outside of the unit with a damp cloth to remove dust and any grease splatter. Pay attention to the vents on the sides and back—these are where hot air exits, and dust buildup can reduce airflow and cooking performance. Use a soft brush or an old toothbrush to gently brush dust away from the vent slats. A damp cloth can then wipe away any remaining dust.

The control panel and buttons can be wiped with a slightly damp cloth, but avoid getting water into the button seams. If water does get inside, let it air-dry for several hours before plugging the unit back in.

Reassemble once everything is completely dry

Before you put the basket and crisper plate back in, make sure they are completely dry. Any moisture left on them can drip onto the heating element when you turn the unit on. If they're still damp, dry them with a clean cloth or let them air-dry for 15 to 20 minutes.

Slide the crisper plate back onto its ledge first, then lower the basket into place. Make sure both parts sit flat and find. The basket should not wobble or shift when you gently shake it. Once everything is in place, you're ready to use the unit again.

Maintenance tips to reduce cleaning time

Line the crisper plate with aluminum foil or parchment paper before cooking. This catches most of the grease and crumbs, so you can straightforward remove and discard the foil instead of scrubbing the plate. Make sure the foil or parchment doesn't block the air vents—leave space around the edges for air to flow.

Wipe the basket and plate when ready after cooking, while they're still warm. This takes two minutes and saves you ten minutes of scrubbing later. If you cook something particularly greasy, like bacon or sausage, wipe the interior walls right away too, before grease cools and hardens.

Check the vents once a week, even if you haven't cooked recently. Dust buildup happens naturally and reduces the unit's heating efficiency. A quick brush with a soft brush takes 30 seconds and keeps your Foodi running at full power.

Frequently Asked Questions

Can I put the basket and crisper plate in the dishwasher?

Yes, both are dishwasher-safe. Place them on the top rack only—the bottom rack's heat can damage the non-stick coating. Hand-washing with warm soapy water and a soft sponge works just as well and takes about the same time.

What should I do if food is stuck on and won't come off?

Soak the basket or plate in warm soapy water for five to ten minutes to soften the food, then scrub gently with a soft sponge. For really stubborn spots, make a paste of baking soda and water, let it sit for three to five minutes, then scrub. Never use steel wool or abrasive scrubbers—they scratch the non-stick surface.

Can I spray water inside the main unit to clean it?

No. Water inside the heating chamber can damage the electrical components. Use only a damp cloth to wipe the interior walls and heating element. Wring out the cloth so it's damp, not wet, and avoid letting water drip into the unit.

How often should I clean the vents?

Check and brush the exterior vents once a week, even if you haven't cooked recently. Dust buildup reduces airflow and heating efficiency. A soft brush takes 30 seconds and keeps the unit running at full power.

What if water gets inside the unit by accident?

Unplug the unit when ready and let it air-dry for at least 24 hours before plugging it back in. Place it in a warm, dry location with good airflow. Do not attempt to use it until you're certain all moisture has evaporated.
