Precaution — Appliance and electrical safety
Clean the drawer, the plate and the element after use. Accumulated grease is what smokes, and then what burns.
How to tell, without a thermometer
- No standing fat under the basket or on the chamber floor
- No brown spatter on the element above the food
- No smoke on an empty preheat — if it smokes with nothing in it, it needs cleaning
If it has not got there: Unplug, let it cool for at least 30 minutes, and clean it. Soak a stuck drawer in warm soapy water rather than scraping it — metal on a non-stick coating creates the next problem.
Why this is the rule
Fat that drips off food does not leave the appliance. It collects under the basket, on the chamber floor, and — the part almost nobody checks — as spatter on the heating element directly above the food. One manufacturer's manual instructs the owner explicitly to inspect the heating coil for oil spatter and food debris and to clean it with a damp cloth. The same manual warns against spraying cooking oil into the chamber, because aerosolised oil on a hot element is a fire risk rather than a convenience. Cleaning after every use is what every manual read this sprint asks for, and the reason it is a safety rule rather than a housekeeping tip is that burnt-on grease on an element is the most common ignition source in this appliance class.
This outranks any cooking time on this site. Where a cooking recommendation cannot be reconciled with a rule like this one, AirfryerHQ does not publish the recommendation — not with a warning attached, not greyed out, not at all.
Evidence and confidence
- Applies to
- Specific to this type of appliance
- Why this rating
- Two manufacturers and the electrical-safety body, with one manufacturer naming the element specifically as a place to inspect — which is the part of this rule that is not obvious and the part that matters.

What this does not cover
- Recorded as a precaution rather than a requirement: no source read states that failing to clean an air fryer causes fires. The link between accumulated grease and ignition is well established in cooking appliances generally and is AirfryerHQ's reasoning here.
