Clean your Ninja air fryer after every use, while it's still warm but unplugged
The fastest way to clean a Ninja air fryer is to wipe the basket and tray while they're still warm—grease comes off easier before it hardens. Unplug the unit first, wait two to three minutes for it to cool enough to touch, then remove the basket and crisper plate (the flat tray underneath). Soak both in hot soapy water for five minutes while you wipe down the main unit with a damp cloth. Most Ninja baskets are dishwasher-safe on the top rack, but hand-washing takes the same time and lets you scrub stubborn spots when ready.
The heating element and interior walls don't need scrubbing after every use—just a quick wipe with a dry cloth to catch loose crumbs. Food particles that fall through the basket land on the crumb tray at the very bottom, which slides out from the front or side depending on your model. Empty this tray into the trash, rinse it, and slide it back. This whole process takes about five minutes and prevents buildup that can smoke or smell.
Key Takeaways
- Always unplug the air fryer and let it cool for two to three minutes before removing any parts.
- The basket and crisper plate are dishwasher-safe on the top rack, but hand-washing in hot soapy water works just as well and is faster for daily cleaning.
- Empty the crumb tray after every use to prevent grease buildup and smoke during your next cooking session.
- Wipe the interior walls and heating element with a dry cloth only—do not use water or scrub them.
- Soak stuck-on food in the basket for five to ten minutes before scrubbing to avoid damaging the nonstick coating.
Remove and soak the basket and crisper plate
Once the air fryer has cooled slightly, locate the basket handle and pull it straight out toward you. The crisper plate sits underneath the basket and usually slides out the same way, though some models require you to lift it at an angle. Place both pieces in a sink filled with hot water and a squirt of dish soap. Let them soak for five to ten minutes—this softens any stuck-on food and makes scrubbing much easier.
After soaking, use a soft sponge or cloth to wipe the basket's interior and exterior surfaces. Pay special attention to the corners and the mesh bottom, where grease tends to collect. For stubborn spots, a soft-bristled brush works better than a scouring pad, which can scratch the nonstick coating. Rinse both pieces under running water until the water runs clear, then set them on a clean towel to air-dry before reassembling.
Clean the interior walls and heating element
The inside of the air fryer chamber needs only a dry wipe after most meals. Crumbs and loose food particles fall through the basket onto the crumb tray below, so the walls stay relatively clean. Use a dry cloth or paper towel to wipe the interior surfaces, including the top where the heating element sits. Do not spray water directly into the chamber or use a wet cloth on the heating element—moisture can damage the electrical components.
If you see grease splatter on the interior walls, wait until the unit is completely cool and unplugged, then use a barely damp cloth to wipe it away. Squeeze out excess water from the cloth first so it's almost dry. For stubborn spots, dampen a cloth with a 50/50 mix of white vinegar and water, wipe the spot, and when ready dry it with a clean cloth. Never soak the interior or let water pool inside the chamber.
Empty and rinse the crumb tray
The crumb tray is the shallow pan that slides out from the bottom front or side of your air fryer—check your manual if you're not sure which direction it moves. After every use, pull it out and dump any crumbs and grease into the trash. Rinse it under warm running water and wipe it dry with a cloth. This takes thirty seconds and prevents grease from building up and smoking during your next cooking session.
If the tray has stuck-on grease, soak it in hot soapy water for a few minutes, then scrub it with a soft sponge. Most crumb trays are dishwasher-safe, but hand-washing is faster for daily cleaning. Slide the tray back into place until you hear or feel it click—it should sit flush with the bottom of the unit. A loose tray can rattle during cooking or allow grease to drip onto your countertop.
Wash the basket and crisper plate in the dishwasher or by hand
Both the basket and crisper plate can go on the top rack of your dishwasher, where water pressure is gentler than the bottom rack. Use your normal dishwasher detergent and run a regular cycle. The top rack keeps them away from the heating element at the bottom, which can warp plastic handles or damage nonstick coatings over time.
Hand-washing is just as fast and gives you more control over scrubbing. Soak the pieces in hot soapy water for five minutes, scrub with a soft sponge, rinse thoroughly, and air-dry on a clean towel. Never use steel wool, scouring powder, or abrasive scrubbers—these scratch the nonstick surface and make food stick during cooking. If you see scratches forming, the basket is still safe to use, but food may stick more easily.
Wipe down the exterior and cord
The outside of your Ninja air fryer collects dust and grease splatter over time. Once a week or whenever you notice buildup, unplug the unit and let it cool completely. Use a damp cloth to wipe the exterior surfaces, including the top, sides, and front panel. For the display screen or buttons, use a barely damp cloth and wipe gently—do not spray water directly on electronics.
The power cord can be wiped with a dry cloth to remove dust. Never submerge the cord or plug in water. If you see any cracks in the cord or damage to the plug, stop using the air fryer and contact Ninja customer service—a damaged cord is a fire hazard. Store the cord loosely coiled next to the unit rather than wrapped tightly, which can damage the insulation over time.
Deep clean the basket if food is stuck or discolored
If regular washing doesn't remove stuck-on food or brown discoloration inside the basket, soak it longer and use a gentler approach. Fill a bowl with hot water, add a tablespoon of baking soda, and place the basket inside for fifteen to thirty minutes. The baking soda helps loosen stubborn food and removes odors without scratching the nonstick coating. After soaking, scrub gently with a soft sponge and rinse thoroughly.
For brown stains that won't come off, try soaking in a 50/50 mix of white vinegar and water for ten minutes, then scrub and rinse. These stains are usually just discoloration from high heat and don't affect how the basket works, but removing them keeps it looking new. Never use bleach, oven cleaner, or harsh chemicals on any part of your air fryer—these can damage the nonstick coating and leave residue that transfers to your food.
Frequently Asked Questions
Can I put the basket in the dishwasher?
Yes, the basket and crisper plate are dishwasher-safe on the top rack. Place them with the nonstick side facing up so water can reach all surfaces. Avoid the bottom rack, where hotter water and stronger spray can damage the coating over time. Hand-washing takes about the same time and gives you more control.
What should I do if the basket has a burnt smell?
Soak the basket in hot water with baking soda for fifteen to thirty minutes to absorb odors, then scrub and rinse. If the smell persists, try soaking in a 50/50 vinegar and water mix. Run the air fryer empty at 350°F for five minutes with the door open to clear any remaining odor from the chamber itself.
Is it safe to use water inside the air fryer chamber?
No—never spray water directly into the chamber or soak the interior. Water can damage the heating element and electrical components. Use only a barely damp cloth to wipe interior walls, and always make sure the unit is unplugged and completely cool first.
How often should I clean the crumb tray?
Empty and rinse the crumb tray after every use. This prevents grease from building up and smoking during your next cooking session. It takes less than a minute and is the single most important part of keeping your air fryer in good condition.
Can I use steel wool or scouring powder on the basket?
No—steel wool and scouring powder scratch the nonstick coating and make food stick during cooking. Use a soft sponge or soft-bristled brush instead. If the coating is already scratched, the basket is still safe to use, but you may need to use a little more oil to prevent sticking.
