Tip to keep your air fryer/oven in top condition: do NOT use oil sprays with propellants, like PAM. They will accumulate on your air fryer and get burnt and nasty and generally be a lot harder to clean off than a pure oil. I use a sprayer with pure avocado oil and no propellants. Also, give it a good wipe down after every use. You’ll thank yourself later when it’s not a disgusting mess.
