Clean the basket and crisper plate right after cooking

The basket and crisper plate are the parts that touch your food, so they need attention first. Let the air fryer cool for at least 5 to 10 minutes after you unplug it—the basket will be very hot. Once it is cool enough to touch, slide the basket out by gripping the handle and pulling straight toward you.

Soak both pieces in hot soapy water for 5 minutes if food is stuck on. Use a soft sponge or cloth to wipe them down—avoid steel wool or abrasive scrubbers, which can scratch the nonstick coating. Pay special attention to the corners and edges of the basket where grease collects. Rinse under running water until all soap is gone, then dry with a clean towel before putting them back.

The crisper plate (the metal grate that sits inside the basket) comes out separately. Wash it the same way, making sure to clean both the top and bottom surfaces where oil and food particles hide.

Key Takeaways

  • Always unplug the air fryer and let it cool for at least 5 to 10 minutes before removing the basket and crisper plate.
  • Soak stuck-on food in hot soapy water for 5 minutes, then wipe with a soft sponge—never use steel wool or harsh scrubbers on the nonstick surface.
  • The heating element and interior walls collect grease buildup and should be wiped down with a damp cloth every few uses, not just after each meal.
  • The exterior housing and vents need only a quick wipe with a dry cloth to remove dust and prevent airflow blockage.
  • Reassemble the basket and crisper plate completely before plugging the air fryer back in, or the unit will not heat properly.

Wipe down the interior walls and heating element

While the basket is soaking, take a damp cloth and wipe the inside walls of the cooking chamber. Grease and food particles splatter during cooking and stick to these surfaces. You do not need to do this after every single use—every two or three uses is fine—but it prevents buildup that can smoke or smell bad.

Be careful around the heating element at the top. You can wipe the exterior of it gently with a damp cloth, but do not spray water directly on it or soak it. If you see heavy grease buildup on the heating element itself, let it cool completely and use a dry cloth to wipe it. Never use water on the element directly, as moisture can damage it.

If the interior has stubborn, baked-on spots, dampen a cloth with a little white vinegar and wipe those areas. The vinegar cuts through grease without harming the nonstick coating. Let it air dry after wiping.

Clean the exterior and air vents

The outside of your Ninja Foodi XL needs less attention than the inside, but it still matters. Use a dry cloth to wipe down the exterior housing, paying attention to the vents on the sides and back. Dust and grease can block these vents and reduce airflow, which makes the air fryer work harder and cook unevenly.

If the exterior is greasy, dampen the cloth slightly with water and wipe it down, then dry it when ready with a clean towel. Do not spray water directly on the unit or let moisture drip into the vents. The control panel and buttons can be wiped with a slightly damp cloth as well, but avoid getting water into the button seams.

Reassemble and store correctly

Once the basket and crisper plate are completely dry, slide the crisper plate back into the basket first—it sits flat on the bottom. Then slide the entire basket back into the air fryer until you hear or feel it click into place. This is important: if the basket is not seated properly, the heating element will not work and your food will not cook.

Before you plug the unit back in, do a quick visual check. The basket should sit level inside the chamber, and there should be no gaps between the basket and the walls. If something feels loose or off, unplug it and reseat the basket.

Store the air fryer in a cool, dry place away from water sources. If you store it in a cabinet, make sure there is at least 4 inches of clearance on all sides for air to circulate. Never store it with the basket inside if the basket is still damp.

What to do about stubborn, baked-on food

Sometimes food sticks so hard that regular washing does not budge it. Fill the basket with hot water and add a tablespoon of baking soda, then let it soak for 15 to 20 minutes. The baking soda helps loosen baked-on residue without scratching the nonstick surface.

After soaking, use a soft sponge or plastic scraper (not metal) to gently work at the stuck food. If it still will not come off, soak it again for another 10 minutes. Patience works better than force—scrubbing hard can damage the nonstick coating and make future cleanup harder.

For the crisper plate, the same baking soda soak works well. You can also use a plastic brush with soft bristles to scrub between the wires where food hides.

Prevent grease buildup and odors

The best way to keep your Ninja Foodi XL clean is to prevent heavy grease buildup in the first place. Pat foods dry before putting them in the basket—excess moisture turns to steam and grease splatters everywhere. If you are cooking something very fatty, like bacon or sausage, line the bottom of the basket with a piece of parchment paper (make sure it does not cover the air vents).

If your air fryer starts to smell bad or smoky, it is usually because grease has built up on the heating element or interior walls. Wipe those areas down more often—weekly if you use the air fryer several times a week. A quick wipe takes 2 minutes and prevents the smell from getting worse.

Never use cooking spray inside the basket. Most cooking sprays leave a sticky residue that builds up fast and is hard to remove. Instead, toss your food in a little oil before cooking, or use the air fryer's own heat to cook without added fat.

Common mistakes that damage the nonstick coating

The nonstick surface on your basket is durable, but it can be damaged by the wrong cleaning method. Steel wool, scouring pads, and abrasive cleaners will scratch it. Once scratched, the coating breaks down faster and food starts to stick. Stick to soft sponges and cloths only.

Do not soak the basket in the dishwasher or put it on the hot cycle. The high heat and harsh detergent can wear down the nonstick coating over time. Hand washing with warm soapy water is gentler and makes the coating last longer. If your basket is dishwasher-safe according to your manual, use the gentle or low-heat cycle only.

Avoid using metal utensils inside the basket while cooking or cleaning. Metal scratches the surface. Use wooden or silicone utensils instead, and clean with soft tools only.

Frequently Asked Questions

Can I put the basket in the dishwasher?

Check your user manual first—some Ninja Foodi XL baskets are labeled dishwasher-safe on the bottom. If yours is, use the gentle or low-heat cycle only. Hand washing with warm soapy water is gentler on the nonstick coating and makes it last longer, so hand washing is the better choice even if the dishwasher is an option.

How often should I deep clean the heating element?

A quick wipe with a damp cloth every two or three uses is enough for most people. If you cook fatty foods often or notice smoke or smell, wipe it weekly. A full deep clean of the heating element is rarely needed—just keep grease from building up with regular light cleaning.

What if water gets inside the air fryer?

Unplug it when ready and let it sit unplugged for at least 24 hours to dry completely. Do not plug it back in until you are sure all moisture is gone. If water got into the control panel or electrical parts, it is safer to contact Ninja customer service before using it again.

Is it normal for the basket to stick when I pull it out?

A little resistance is normal, but it should slide out smoothly. If it is sticking badly, the basket may not be seated correctly or grease has built up on the rails. Unplug the unit, let it cool, and wipe the rails inside the chamber with a dry cloth. Make sure the basket clicks all the way in when you put it back.

Can I use vinegar or lemon juice to clean the interior?

Yes, white vinegar works well on grease and stubborn spots. Dampen a cloth with vinegar and wipe the interior walls and heating element exterior. Lemon juice works similarly. Avoid vinegar on the nonstick basket itself—stick to warm soapy water for that. Vinegar is best for the chamber walls and heating element.
