An air fryer that is not cleaned properly does two things: it starts smoking from built-up grease residue, and it slowly loses cooking performance as leftover oil affects airflow and heat distribution. The good news is that cleaning one properly takes a few minutes, not a deep-cleaning session, regardless of whether your basket is glass, ceramic or non-stick.
Unplug and let it cool completely before cleaning, for both safety and to avoid thermal shock to a glass bowl. Wash with warm water and standard dish soap , using a soft sponge for coated surfaces or a slightly more abrasive sponge for uncoated glass or stainless steel if residue is stuck on. Wipe the interior heating chamber and base with a damp (not wet) cloth, since this part should not be submerged in water. This is where glass has a genuine, practical advantage. Most glass air fryer bowls, including EDT’s LUMA, are also dishwasher safe per the manufacturer, which removes hand-washing from the routine entirely for that component. Full details on LUMA’s specific bowl construction and care are in the LUMA air fryer guide . A burning smell during use almost always comes from leftover oil or food particles from a previous session, heating up again rather than a defect in the appliance. If this happens:
Because there is no coating to protect, you can use a slightly more abrasive sponge or a baking-soda paste on stuck-on residue without worrying about scratching away a protective layer, since the glass itself is the cooking surface.
