How to Keep Your Ninja Air Fryer Clean and Working Well

Start with the basket and tray after every use

The basket and crisper tray are the parts that touch your food, so they need cleaning right after cooking. Let them cool for a few minutes, then remove them from the unit. Most Ninja air fryer baskets and trays are dishwasher-safe — check your manual to confirm, since some older models have a non-stick coating that hand-washing protects better.

If you hand-wash, use warm soapy water and a soft sponge or cloth. Avoid steel wool or abrasive scrubbers, which scratch the non-stick surface and shorten the basket's life. For stuck-on food, soak the basket in warm water for 10 to 15 minutes before scrubbing. Dry everything completely before putting it back in the unit — water left inside can drip onto the heating element and cause rust or electrical issues.

Key Takeaways

• Clean the basket and tray after every use by hand-washing with a soft sponge or running them through the dishwasher, depending on your model.
• Wipe the interior chamber with a damp cloth weekly to remove grease buildup and prevent smoke and odors during cooking.
• Never submerge the main unit or heating element in water — they contain electrical parts that will be damaged.
• Store your air fryer in a dry place and keep the cord wrapped loosely to avoid kinks that can damage the wire over time.

Wipe the interior chamber weekly

The inside of your air fryer collects grease and food particles that fall from the basket during cooking. This buildup can smoke, smell, and eventually affect how evenly your food cooks. Once a week, unplug the unit and let it cool completely. Use a damp cloth or soft sponge to wipe the interior walls, floor, and the underside of the lid.

Pay special attention to the heating element at the top — grease that pools there burns and creates smoke. Wipe gently around it without pressing hard or using anything abrasive. If you see stubborn grease, dampen the cloth with a little warm water and a drop of dish soap, then wipe again. Never spray water directly into the unit or use a hose, which can force moisture into electrical components.

Never submerge the main housing or heating element

The main unit — the part with the cord and controls — contains the heating element and electrical wiring. Water inside these parts causes rust, short circuits, and permanent damage. The basket and tray are designed to be removed and washed separately, but the housing itself should only be wiped on the outside with a damp cloth.

If liquid spills inside the unit during cooking, unplug it immediately and let it dry for at least 24 hours before using it again. Do not try to speed up drying by opening vents or using heat. If water has been inside for more than a few hours, the unit may need professional inspection before you use it, because moisture can cause electrical hazards.

Clean the exterior and cord regularly

Wipe the outside of your Ninja air fryer with a soft, dry cloth after it cools. If there is grease splatter on the exterior, use a slightly damp cloth with a tiny bit of dish soap, then dry it immediately. Never use harsh chemicals, bleach, or abrasive cleaners on the housing, as they can damage the finish and the plastic components.

Check the power cord once a month for cracks, fraying, or damage. If you see any, stop using the unit and contact Ninja customer service — a damaged cord is a fire and shock hazard. When storing the air fryer, wrap the cord loosely around the base or use a velcro strap. Tight coiling or kinking can damage the wire inside the cord over time and create a safety risk.

Store your air fryer in a dry place

Keep your Ninja air fryer in a cabinet, pantry, or countertop spot that stays dry and away from direct sunlight. Moisture in the air — from a dishwasher, sink, or humid climate — can corrode the heating element and electrical contacts over time. If you live in a very humid area, store the unit with a small packet of silica gel or uncooked rice nearby to absorb excess moisture.

Make sure the basket and tray are completely dry before you put them back in the unit for storage. Any water left inside can pool and cause rust on the metal parts. If you are storing the air fryer for more than a month, wipe the interior one more time before putting it away, and check it again before using it.

Address common problems before they spread

If your air fryer starts smoking during cooking, unplug it and let it cool. The most common cause is grease buildup on the heating element or interior walls. Clean the interior thoroughly with a damp cloth, then dry it completely before using the unit again. Smoke can also mean you are cooking food with too much oil — pat your ingredients dry before cooking to reduce splattering.

If you notice rust spots on the basket or tray, soak the affected area in white vinegar for 15 to 20 minutes, then scrub gently with a soft sponge and rinse well. Dry immediately. Small rust spots can be stopped early this way, but if rust covers a large area or the basket has holes, the basket needs to be replaced. Contact Ninja to order a replacement basket for your specific model.

Organize your storage to protect the unit

Store the basket and tray in a clean, dry drawer or cabinet near your air fryer so you can grab them quickly when you cook. Keep them away from sharp objects that could puncture the non-stick coating. If you stack other items on top of the basket, use a cloth or paper towel as a barrier to prevent scratches.

Keep the instruction manual and any warranty paperwork in a folder near the unit. You will need the model number if you ever contact Ninja about replacement parts or repairs. Store any extra accessories — like a rack insert or baking pan — in the same spot so everything stays together and nothing gets lost.

Frequently Asked Questions

Can I put my Ninja air fryer basket in the dishwasher?

Most Ninja air fryer baskets are dishwasher-safe, but check your manual first — some older models or specialty baskets should be hand-washed to protect the non-stick coating. If your manual says it is dishwasher-safe, place the basket on the top rack and use a gentle cycle. Hand-washing with a soft sponge will always extend the basket's life.

What should I do if water gets inside the main unit?

Unplug the air fryer immediately and do not use it. Let it sit unplugged in a warm, dry place for at least 24 hours. If water was inside for more than a few hours, contact Ninja customer service before plugging it back in, because moisture can create electrical hazards. Never try to dry the inside with heat or by opening vents.

Why is my air fryer smoking during cooking?

Smoke usually comes from grease buildup on the heating element or interior walls. Unplug the unit, let it cool, and wipe the inside thoroughly with a damp cloth. Dry completely before using again. You can also reduce smoke by patting your food dry before cooking and using less oil — excess oil splatters and burns on the heating element.

How often should I deep-clean the interior?

Wipe the interior with a damp cloth weekly to remove grease and food particles. Once a month, do a more thorough cleaning by removing the basket and tray and wiping all interior surfaces, including the heating element area and the lid. This prevents smoke, odors, and uneven cooking.

Is it safe to store my air fryer in a cabinet?

Yes, as long as the cabinet is dry and has good air circulation. Make sure the basket and tray are completely dry before storing them inside the unit. Avoid storing the air fryer in damp places like under a sink or in a bathroom, where humidity can corrode the heating element and electrical parts over time.
