The fastest way to clean your Ninja 8-in-1

The Ninja 8-in-1 air fryer has a removable basket and crisper plate that come out easily, and both go in the dishwasher on the top rack. Wipe the interior chamber with a damp cloth while it is still warm (but unplugged and cooled for a few minutes), and you are done. Most of the mess stays on the basket and plate, so the whole job takes about five minutes if you do it right after cooking.

The heating element and heating coil sit above the chamber and do not need cleaning after every use. Food particles that fall during cooking burn off on their own at high heat, and wiping them risks damaging the element. You will see some browning and buildup there over time—that is normal and does not affect performance.

Key Takeaways

  • Remove the basket and crisper plate when ready after cooking and rinse them under warm water while they are still warm, which loosens stuck food faster than waiting.
  • Both the basket and crisper plate are dishwasher-safe on the top rack, or hand-wash them with a soft sponge to avoid scratching the nonstick coating.
  • Wipe the interior chamber with a damp cloth or soft sponge while the unit is unplugged and has cooled for a few minutes after cooking.
  • Do not scrub or spray the heating element above the chamber; food particles burn off on their own during normal cooking.
  • Clean the exterior housing with a dry cloth, and wipe the control panel with a slightly damp cloth only if needed.

Removing and rinsing the basket and crisper plate

Pull the basket straight out toward you—it slides out on rails and does not require twisting or tilting. The crisper plate sits inside the basket and lifts out separately. Rinse both under warm running water as soon as you finish cooking, while they are still warm. Warm water and a soft sponge or cloth remove stuck-on food much faster than cold water, because the heat keeps the oils and residue soft.

For stubborn spots, soak the basket and plate in warm soapy water for five to ten minutes, then scrub gently with a soft sponge. Avoid steel wool, scouring pads, or abrasive brushes, which scratch the nonstick coating and shorten its life. If food is really stuck, a plastic scraper or old credit card works well without damaging the surface.

Dishwasher versus hand-washing

Both the basket and crisper plate are dishwasher-safe and can go on the top rack. The top rack keeps them away from the heating element at the bottom of the dishwasher, which is important for nonstick cookware. If you hand-wash, use warm soapy water and a soft sponge, and dry them right away to prevent water spots.

Hand-washing is gentler on the nonstick coating over time, but the dishwasher is faster and works well if you place them correctly. Never put them on the bottom rack, and do not use the heat-dry setting—air-dry them instead or dry them by hand with a cloth.

Cleaning the interior chamber

Unplug the unit and let it cool for three to five minutes after cooking. The interior gets hot, and you want to avoid burns. Once it is cool enough to touch, wipe the inside walls and bottom with a damp cloth or soft sponge. You do not need soap for this step—warm water alone removes most residue.

If grease or food has splattered on the walls, a slightly soapy cloth works, but rinse the cloth well so you do not leave soap residue inside. Wipe until the chamber looks clean, then do a final pass with a dry cloth to remove excess moisture. Do not spray water directly into the chamber or pour water inside; a damp cloth is all you need.

What not to clean and why

The heating element and heating coil sit above the basket and do not need cleaning after every use. During cooking, any food particles that fall onto the coil burn off completely at high temperature. Trying to wipe or scrub the element risks damaging it or getting water where it should not be, which can cause electrical problems.

Over weeks and months, you will see some browning and carbon buildup on the coil—this is normal and does not affect how the air fryer works. If you want to check it, look up into the chamber with a flashlight, but do not touch it. If something large falls into the chamber during cooking, unplug the unit, let it cool, and use a long wooden spoon or plastic tool to gently push it toward the basket opening so you can remove it.

Cleaning the exterior and control panel

Wipe the outside housing with a dry cloth after each use to remove dust and splatters. If there are sticky spots or grease on the outside, use a cloth that is barely damp—not wet—and wipe gently. Dry it right away with another cloth.

The control panel and buttons can be wiped with a slightly damp cloth if they get dirty, but do not spray water on them or let water drip into the seams. Unplug the unit first, let it cool, and use a cloth that is wrung out well so it is damp but not wet. Dry the panel when ready after wiping.

Preventing buildup and keeping your air fryer in shape

The easiest way to keep your Ninja 8-in-1 clean is to wipe the basket and chamber right after cooking, while everything is still warm. Dried-on food is much harder to remove than food that is still soft. If you cook fatty foods like bacon or sausage regularly, the basket may need a soapy wash more often than if you cook leaner foods.

Check the basket and crisper plate every few months for any damage to the nonstick coating. Small scratches are normal and do not affect cooking, but if the coating is peeling or flaking, the basket may need to be replaced. Ninja sells replacement baskets and crisper plates separately, so you do not have to buy a whole new unit.

Frequently Asked Questions

Can I put the basket in the oven to clean it?

No. The basket is designed for the air fryer only and may warp or be damaged by oven heat. Stick to hand-washing or the dishwasher top rack. If you need to loosen really stuck food, soak it in warm soapy water for ten minutes instead.

What if water gets inside the heating element area?

Unplug the unit when ready and let it sit unplugged for at least an hour so any moisture can evaporate. Do not plug it back in until you are sure it is completely dry. If you are worried water got into electrical components, wait overnight before using it again.

Is it okay to use cooking spray in the Ninja 8-in-1?

Cooking spray can build up on the basket and heating coil over time, making cleaning harder. The nonstick coating is already effective, so spray is usually not needed. If you do use it, clean the basket more thoroughly afterward to prevent sticky residue from accumulating.

How often should I deep-clean the air fryer?

A quick wipe after each use is usually enough. Once a month, you can do a deeper clean by soaking the basket and crisper plate for ten minutes, then scrubbing gently and rinsing well. The interior chamber rarely needs more than a damp-cloth wipe unless something has splattered heavily.

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

Yes, a cloth dampened with white vinegar or lemon juice can help cut through grease on the interior walls. Wipe with the vinegar or juice, then wipe again with a damp cloth to rinse, and finish with a dry cloth. Do not soak the basket in vinegar, as it can damage the nonstick coating over time.
