How to Clean Grease in Air Fryer Air Duct Gaps: 2 Low-Cost Tricks Without Damaging the Machine

Have you also struggled with cleaning your air fryer?

Last weekend, I roasted a whole tray of Orleans chicken wings and fries with my air fryer at home. After eating, I wiped the fryer basket and the inner wall of the cavity clean, only to catch sight of yellowish oil stains in the air duct gaps. I scraped at them with my nails for ages and only got a little hardened grease off, plus there was a stale oil smell left from the last time I roasted pork belly, which instantly killed my mood to use it next time. I previously went through 97,574 real user reviews of air fryers, and found that 21% of negative reviews are related to difficulty cleaning. Most people can only reach and wipe the fryer basket, while the accumulated oil in the air duct and around the heating tube is completely out of reach. Over time, it not only causes flavor transfer, but also easily breeds bacteria. Does that sound exactly like you?

Why is cleaning so difficult? — Figure out the reason in 2 minutes

Actually, the core reason is very easy to understand: air fryers heat food through hot air circulation. The oil splatters and food crumbs produced during roasting are carried everywhere by the high-speed circulating hot air. Apart from falling into the fryer basket, a large part of them will drift into the air duct gaps and stick to the heating tube and the corners of the inner cavity. This is the same as eating hot pot in front of a running standing fan: after a short while, the gaps between the fan blades are full of oil spots. The oil hidden in the gaps cannot be wiped in daily cleaning, it accumulates a little every time you use the fryer, and over time it turns into hard old grease that you can barely scrape off. Two real user feedbacks I saw before are very representative: one said “I only remembered to clean the air duct after 3 months of use, the grease I scraped out was already black, I scrubbed for more than half an hour and there was still residue”, the other said “The oil splashed on the heating tube when I roasted pork belly last time was not wiped clean, every time I turn on the fryer after that there is a burnt smell, I don’t dare to scrub hard for fear of damaging the heating tube, so I can only make do with it”. I believe many of you have the same trouble.

Practical guide to solving cleaning difficulties

Tip 1: Hot steam dissolution method, get rid of deep air duct grease in 15 minutes

How to do it: Wait 5 minutes after using the air fryer, when it cools down to a non-scalding temperature, pour half a small bowl of warm water into the fryer basket, add 2 spoons of edible baking soda + 1 spoon of regular dish soap. Turn on the fryer at 180℃, run for 5 minutes then cut off the power, let it stew for 10 minutes before opening the lid. Then take an unused old toothbrush, wrap two layers of kitchen paper around it, reach into the air duct gaps and around the heating tube and wipe around. The softened grease will be stuck off directly, and the oil on the corners of the inner cavity can be wiped off with a damp cloth easily. Why it works: The hot air will carry the steam of dish soap and baking soda to circulate throughout the entire inner cavity and air duct. The hot steam can soften the hard grease, and baking soda itself has strong degreasing power. No hard scraping is needed, and it will not scratch the coating, the cost is only a few cents. Note: Do not open the lid and pour cold water right after use, sudden temperature change can easily damage the inner cavity coating. Also do not scrub hard with steel wool, as scratches will make oil accumulation easier later on.

Tip 2: Daily light maintenance, reduces oil accumulation probability by 80%

How to do it: ① Every time you roast oily food (such as pork belly, chicken wings, sausages), line the fryer basket with parchment paper or an oil separation rack first. Do not use inferior thin parchment paper that breaks easily, as oil leakage will cause more trouble; ② Do not cover the storage lid right after use, run it empty at 100℃ for 3 minutes to dry the remaining small oil droplets and moisture in the air duct, so it will not get moldy and smelly when closed up; ③ Every time you wash the fryer basket, wipe the inner wall of the cavity with a damp cloth by the way, do not wait until the oil accumulates thickly to deal with it. Why it works: It reduces the amount of oil droplets drifting into the air duct from the source. Spending 3 minutes on it every time can save you 1 hour of deep cleaning later.

How to avoid cleaning difficulties when purchasing an air fryer?

Design details worth paying attention to

1. Prioritize seamless inner cavity: Whether it is food-grade stainless steel or non-stick coated, prioritize inner cavities with no splicing seams. Seamed areas are very easy to trap food crumbs and grease, which you can not even wipe, and are a heavy disaster area for hidden dirt.
2. Prioritize design with removable and washable air duct cover: This design is really worth spending dozens of extra bucks on. You can unscrew the screws to take off the air duct cover and rinse it directly, no need to scrape the gaps, cleaning efficiency is increased by 10 times.
3. Choose hidden/sunken heating tube: It is much easier to wipe than the fully exposed type. Oily food will not splatter all over the heating tube when roasting, and it is not easy to be damaged during wiping.

Pitfall avoidance list

• Do not believe the宣传 of “fully automatic self-cleaning, no need to wipe at all”: Current self-cleaning functions basically use high temperature steaming/roasting to soften grease, you still have to wipe it yourself after softening. Truly wipe-free products are not popularized yet, do not pay the IQ tax.
• Do not believe the saying of “air duct never accumulates oil”: As long as it adopts hot air circulation structure, it will definitely carry oil droplets into the air duct, it is impossible to have zero oil accumulation, it is only a difference of how much. Claims of never accumulating oil are exaggerated advertising.

Summary

Actually, cleaning an air fryer is really not that troublesome. You don’t need to buy expensive special cleaners, the hot steam dissolution method can solve the hard-to-wipe air duct grease problem, and doing a good job of daily light maintenance can reduce most oil accumulation problems. When purchasing, choose models with seamless inner cavity and removable air duct, which can save you a lot of cleaning work later.
