How To Clean Ninja Air Fryer Inside | No Harsh Scrubbing

You just pulled a batch of crispy fries from your Ninja air fryer, but now there’s a grease splatter on the basket and a faint burnt smell inside. Scrubbing too hard risks scratching the non-stick coating, while skipping a deep clean lets buildup smoke during future cooks.

The good news is that cleaning the inside of a Ninja air fryer doesn’t require special chemicals or hours of elbow grease. A simple routine — unplug, cool, wipe, and wash — keeps it performing like new. Most models also let you toss the basket in the dishwasher for an easier deep clean.

First Things First: Unplug and Cool

Before you touch any part of the machine, unplug the unit and let it cool completely. The interior and heating element stay hot long after cooking ends, and a wet sponge on a hot surface can cause steam burns or electrical shorts.

Once the air fryer is cool, wipe the exterior with a warm, damp cloth or sponge. For the inside, use a non-abrasive sponge to avoid damaging the non-stick coating. Harsh scrubbing pads or steel wool are a no-go — they’ll strip the coating and leave the surface prone to sticking.

The heating element inside also needs occasional attention. After the unit is cool and unplugged, gently wipe away food splatter with a damp cloth or soft brush. A buildup there can cause smoking during future cooks.

Why Clean Air Fryers Are Easier Than You Think

One reason Ninja air fryers stay popular is their relatively simple cleanup. Unlike deep fryers, they don’t require handling large quantities of used oil — just a quick wash and wipe. Here’s why that matters:

• Easier than deep fryers: Air fryers circulate hot air rather than submerging food in oil, so grease splatter is minimal and cleanup is faster.
• Quick wipe between uses: After the unit cools, a damp paper towel wiped across the interior prevents grease and food residue from hardening.
• Test run before first use: Most manufacturers recommend washing the basket and wiping the interior and exterior before cooking in a new air fryer — it removes any factory residues.
• Clean after each use: Regular cleaning maintains performance and prevents smoke from burnt-on residue during future cooking.

Because the basket and crisper plate handle most of the mess, a daily clean takes under two minutes. The interior itself usually just needs a quick wipe.

The Right Tools and Techniques for the Interior

Keeping the inside of your Ninja air fryer clean starts with the right approach. Mild cleaning solutions — warm soapy water or a gentle degreaser — work well without harming the non-stick coating. Serious Eats recommends you unplug and cool air fryer before any cleaning, then use a non-abrasive sponge to avoid scratches.

For routine cleaning, wet a sponge with the hottest water from the tap and wipe the interior surfaces. This loosens light grease and food particles without needing soap. If you have stubborn spots, a little mild dish soap on the sponge is fine.

For burnt-on grease, a baking soda paste works wonders. Mix baking soda with a little water to form a thick paste, apply it to the affected areas, let it sit for a few minutes, then scrub gently with a non-abrasive sponge. This method is kitchen-tested and safe for non-stick surfaces.

Most Ninja air fryer baskets and crisper plates are dishwasher-safe. They take up significant space in the dishwasher, but it’s an easy way to get a deep clean without scrubbing. Hand-washing with hot soapy water and a non-abrasive sponge is just as effective if the dishwasher is full.

Step-by-Step: How to Clean Ninja Air Fryer Inside

A reliable routine keeps your air fryer in top shape. Follow these steps after each use for best results:

1. Unplug and cool completely. This is the most important step. Never clean a hot air fryer — you risk burns and damage to the machine.
2. Remove the basket and crisper plate. Wash them in the dishwasher or by hand with hot soapy water and a non-abrasive sponge. Soak if food is stuck.
3. Wipe the interior with a warm damp cloth. Use the hottest tap water for best grease removal. For stubborn spots, a little baking soda paste works.
4. Clean the heating element gently. Use a damp cloth or soft brush only after the unit is cool and unplugged. Avoid getting water into the element.
5. Dry everything completely. A damp air fryer can cause steam and poor cooking results. Let all parts air dry or towel dry before reassembling.

A quick wipe-down between uses — just a damp paper towel after the unit cools — prevents buildup and keeps the interior fresh. That daily habit makes deep cleaning less frequent and easier.

Tackling Stubborn Grease and Burnt-On Food

Sometimes a routine wipe-down isn’t enough, especially after cooking fatty meats or glazed vegetables. For heavy grease and burnt-on residue, a deeper cleaning method is needed.

Per the baking soda hydrogen peroxide paste method from The Kitchn, combine 2 tablespoons of baking soda, 2 tablespoons of hydrogen peroxide, and a couple sprays of dish soap. Apply this mixture directly to the greasy basket or interior surfaces and scrub with a non-abrasive sponge. The chemical reaction helps break down stubborn grease without harsh chemicals.

Another effective duo is vinegar and baking soda. Sprinkling baking soda inside the basket, then spraying white vinegar on top creates a fizzing reaction that lifts burnt bits and neutralizes odors. Let it sit for a few minutes before wiping clean. Both methods are kitchen-tested hacks that work well on non-stick surfaces.

Avoid vinegar on the heating element or any exposed metal parts, as acidity can cause corrosion over time. Stick to the baking soda paste for those areas.

The Bottom Line

Cleaning the inside of your Ninja air fryer boils down to three habits: always unplug and cool first, use non-abrasive tools and mild cleaners, and tackle heavy residue with a baking soda paste or a quick dishwasher cycle. A two-minute wipe after each use prevents buildup and keeps the machine running smoothly.

For a Ninja model with a removable basket, try the baking soda and hydrogen peroxide paste when grease seems stubborn — it’s a kitchen-tested method that cuts through buildup without damaging the coating, so your next batch of fries cooks evenly and smoke-free.
