Still choosing a model? Our best Ninja air fryer UK comparison covers the current range, and the parts and accessories section lists liners and racks.

Before you start

  • Switch off and unplug the air fryer.
  • Let it cool completely. The drawers, crisper plates and heating area stay hot for a while after cooking.
  • Never put the main unit in water or under a running tap.

How to clean a Ninja air fryer after each use

  1. Empty the drawer. Pour away any fat that has collected under the crisper plate.
  2. Wash the drawer and crisper plate. Use warm soapy water and a soft sponge. Many Ninja listings describe these parts as dishwasher safe, but check your manual for your exact model.
  3. Dry everything fully before putting it back.
  4. Wipe the outside with a damp cloth.

How to deep clean a Ninja air fryer

  1. Soak stubborn residue. Leave the drawer and crisper plate in warm soapy water for 10 to 15 minutes before wiping.
  2. Clean the inside of the unit. With the unit cool and unplugged, wipe the cavity with a damp, non-abrasive cloth. Be gentle around the heating element.
  3. Check the vents. Make sure nothing is blocking the air inlets and outlets.

What not to do

  • Don’t use metal scourers, abrasive pads or harsh cleaners on non-stick parts.
  • Don’t use metal utensils inside the drawer; they can scratch the coating.
  • Don’t spray aerosol cooking oil directly onto non-stick surfaces, which can leave a sticky build-up over time.

Cleaning a Ninja CRISPi glass air fryer

The CRISPi uses glass containers instead of a drawer. Let the glass cool before washing, as sudden temperature changes can stress glass, and wipe the cooking pod with a damp cloth only.

Do liners make cleaning easier?

Reusable silicone liners or parchment liners catch drips and cut down on scrubbing. Choose liners sized for your model and leave room for air to circulate. For example, there are silicone liners for the AF300UK and AF400UK and liners for the Double Stack SL300UK and SL400UK. These are third-party products, not made by Ninja.

FAQs

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

On many models, yes, but check your manual. Hand washing with a soft sponge is gentler on the coating.

Why does my Ninja air fryer smoke?

Often it’s old grease in the drawer or fat from high-fat foods. Emptying and cleaning the drawer after each use usually helps.

How often should I deep clean it?

A quick clean after every use, and a deeper clean every few weeks or whenever you notice build-up, suits most households.
