No more stressing over greasy trays or racks! By the end of this post, you’ll be able to tackle grease with confidence and ensure your air fryer oven stays in top shape for every meal. Let’s dive in!

Understanding the Cause of Baked-On Grease in Your Air Fryer Oven
Before we dive into cleaning methods, let’s first understand why baked-on grease even happens in the first place. It’s easy to assume that the grease in your air fryer oven just appears out of nowhere, but it actually builds up over time from cooking oils, food particles, and even some of the naturally occurring fats in meat. When you cook, these substances get splattered or drip onto the walls and surfaces of your air fryer oven, where the heat quickly turns them into stubborn residue.
Why does grease stick?
Air fryers work by circulating hot air to cook your food, and that hot air can cause oils and fats to splatter and stick to the surface of your oven. Think of it like cooking bacon in a pan—the grease pops and splatters everywhere! In your air fryer oven, those tiny droplets of oil can land on the heating element, racks, trays, and interior walls, where they quickly harden into greasy spots. Over time, this buildup makes cleaning a whole lot harder.
Another reason why grease sticks so well is the consistent high temperatures. Most air fryer ovens operate at temperatures ranging from 300°F to 400°F (150°C to 200°C). This intense heat causes the oils to evaporate quickly, leaving behind sticky, baked-on residues. If you’re using your air fryer oven frequently, it’s not unusual for these greasy spots to get caked on, especially in corners or along the heating element.
The problem with ignoring it
Ignoring the grease buildup or neglecting regular cleaning may seem like an easy way to save time, but it can actually cause more problems down the road. For one, the grease can transfer to your food, affecting its flavor and quality.
It can also lead to unpleasant odors every time you cook, as old grease burns and gives off a smoky smell. Not to mention, it can cause uneven cooking, as grease can obstruct the flow of hot air within the oven, making it harder for your air fryer to perform optimally.
By regularly cleaning your air fryer oven, you’ll not only keep your meals tasting fresh but also extend the life of the appliance. Plus, cleaning out the grease regularly helps ensure that your air fryer is running smoothly and safely.
Effective Methods for Removing Stubborn Grease from the Interior
Now that we know why grease builds up in the first place, let’s talk about how to actually remove it. There are a variety of methods for tackling stubborn baked-on grease from your air fryer oven’s interior. Whether you’re dealing with grease on the racks, trays, or walls of the oven itself, these tried-and-true methods will help you get the job done.
Using Baking Soda and Vinegar: A Powerful Combo
If there’s one natural cleaning duo you need to know about, it’s baking soda and vinegar. These two household items are incredibly effective at cutting through grease, lifting stains, and deodorizing. Here’s how you can use them to clean your air fryer oven:
Step 1: Remove Racks and Trays Start by taking out all the removable parts from your air fryer oven, including racks, trays, and crumb trays. These are the easiest components to clean and should be tackled first. Set them aside for now.
Step 2: Create a Cleaning Paste In a small bowl, mix about 3 tablespoons of baking soda with water to create a thick paste. This paste will work wonders on the baked-on grease, as the abrasiveness of the baking soda helps lift the residue without damaging the oven’s surfaces.
Step 3: Apply the Paste to the Interior Using a soft cloth or a sponge, apply the baking soda paste to the greasy areas inside your air fryer oven. Pay extra attention to spots that are especially built-up or hard to reach. Let it sit for about 10 to 15 minutes to allow the paste to break down the grease.
Step 4: Scrub and Rinse After letting the paste sit, gently scrub the surfaces with a non-abrasive sponge. Be patient and give the paste time to work its magic on stubborn spots. Once you’ve scrubbed the grease off, wipe down the interior with a damp cloth to remove the baking soda residue.
Step 5: Vinegar Rinse To get rid of any remaining grease and baking soda paste, spritz some white vinegar onto a cloth or sponge and wipe down the interior. The vinegar will react with any leftover baking soda and help dissolve any remaining greasy residue. It also helps deodorize the oven, leaving it smelling fresh.
Step 6: Clean the Removable Parts While the paste is working on the interior, you can soak the racks and trays in a mixture of warm water and vinegar. This will help loosen any grease and make it easier to scrub off. After soaking for 15-20 minutes, use a soft brush or sponge to scrub away the grease. Dry everything thoroughly before putting it back into the oven.
Using Commercial Oven Cleaners
If the natural methods aren’t quite cutting it for you, don’t worry! There are plenty of commercial cleaners on the market that are specifically designed for tough grease removal. When using a commercial oven cleaner, make sure to follow the manufacturer’s instructions carefully. Here’s how to do it:
Step 1: Choose a Safe Cleaner Look for an oven cleaner that’s safe for use on air fryer ovens. Be sure it’s non-toxic, as you’ll want to avoid any harsh chemicals that might contaminate your food. Products with citrus-based cleaners or degreasers are usually a safe bet.
Step 2: Apply the Cleaner Spray the cleaner on the grease spots inside the air fryer oven. Allow it to sit for the recommended time—usually around 10 to 15 minutes—so that the cleaner can break down the grease.
Step 3: Scrub and Wipe After the cleaner has had time to sit, use a soft sponge or microfiber cloth to scrub the greasy areas. Be careful not to damage any non-stick surfaces or delicate components in the oven.
Step 4: Wipe Down the Oven Once you’ve removed all the grease, wipe down the interior thoroughly with a damp cloth to remove any remaining cleaning product. Always make sure to follow up with a clean water rinse to avoid any chemical residue.
Using a Degreasing Solution
For a more targeted approach to grease, consider using a degreasing solution that’s designed to break down fats. These are particularly effective at cutting through stubborn, stuck-on grease in hard-to-reach places, like the heating element or vents.
Step 1: Apply the Degreaser Spray the degreaser directly on the affected areas. Be sure to follow the instructions carefully, as different products have different recommendations for how long to leave them on. Usually, a 10-15 minute soak is sufficient.
Step 2: Scrub Away Use a soft brush or sponge to scrub away the grease. Make sure to focus on areas with heavy buildup, but don’t be too rough on the surfaces to avoid damaging them.
Step 3: Wipe Clean Once the grease is gone, wipe the oven clean with a damp cloth. Repeat as necessary, especially for areas with stubborn grease buildup.
Preventing Future Baked-On Grease and Easy Maintenance Tips
While cleaning baked-on grease is definitely a task, there are several ways to prevent the problem from happening again in the future. By implementing these easy maintenance tips and tricks, you can keep your air fryer oven clean with minimal effort.
1. Use Parchment Paper or Silicone Liners
A simple but highly effective method to reduce grease buildup is by using parchment paper or silicone liners when cooking. These liners catch food drips and grease, preventing them from splattering onto the walls of the oven. They’re easy to remove and can be discarded or washed after each use, saving you time on cleaning. Just be sure to use liners that are rated for high temperatures and designed for use in air fryers.
2. Avoid Excess Oil
Although the air fryer is known for cooking with little to no oil, some recipes may call for a little extra oil to get that crispy finish. However, it’s important not to overdo it. Excessive oil can drip onto the oven surfaces and contribute to grease buildup. If you’re using oil, consider using an oil sprayer to distribute it evenly and avoid oversaturating your food.
3. Clean After Each Use
While it may seem like extra effort, wiping down the interior of your air fryer oven after each use can make a huge difference. After every cooking session, simply wait for the oven to cool, then use a damp cloth to wipe down the racks, trays, and interior surfaces. If you do this regularly, the buildup won’t get out of hand, and you won’t have to deal with serious grease issues later on.
4. Use a Grill Brush for Hard-to-Reach Areas
If grease tends to accumulate around the heating element or vents, a grill brush can help. These brushes are designed to clean grills and other appliances with tough grease, and their long, bristle design makes them perfect for cleaning hard-to-reach spots. Gently use a brush to dislodge any grease or food residue from these tricky areas.
5. Keep the Exterior Clean Too
Don’t forget about the exterior of your air fryer oven! While it’s the interior that usually gets all the attention, the exterior can accumulate grease and grime as well. Wipe down the outside with a soft cloth and mild dish soap after every use to keep your appliance looking brand new.
I hope this guide has helped you get a better understanding of how to clean baked-on grease from your air fryer oven. By following these simple steps and maintenance tips, your air fryer oven will stay clean, fresh, and working at its best for a long time!
