Burnt grease on an air fryer basket can look permanent, but most buildup comes off with heat, dish soap, soaking, and gentle scrubbing. In a U.S. kitchen, the safest method is to use the cleaning steps in your air fryer manual first, then loosen the grease with a warm baking soda paste if the coating allows it.
Do not use oven cleaner, bleach, steel wool, or a metal scraper. These can damage the nonstick coating and leave the basket unsafe to use.
Quick answer
- Unplug the air fryer and let the basket cool.
- Remove loose crumbs with a soft brush or paper towel.
- Soak the basket in hot—not boiling—water with dish soap for 20 to 30 minutes.
- Apply a paste made from baking soda and a little dish soap.
- Scrub with a soft sponge or nylon brush.
- Rinse well, inspect the coating, and dry the basket fully.
- Repeat once if needed. Replace the basket if the coating is peeling, badly scratched, or exposing metal.

Why burnt grease sticks to an air fryer basket
Burnt grease becomes hard because heat changes the oils left behind by food. As the oil dries and cooks onto the surface, it forms a sticky layer that bonds to the basket. Repeated cooking can create several layers of residue.
Air fryer baskets also have small holes, ridges, and corners. These areas catch oil and food particles. A light wipe may remove fresh grease, but it often cannot reach older buildup.
Many air fryer baskets use a nonstick coating. The exact coating varies by brand and model. A coating may resist food at first, but harsh tools, high heat, and abrasive cleaners can wear it down.
The goal is to soften the grease before scrubbing. Scrubbing harder is usually less helpful than soaking longer.
What you need before cleaning
Gather these items:
- Dish soap that cuts grease
- Hot tap water
- Baking soda
- A soft sponge or microfiber cloth
- A nylon dish brush or soft toothbrush
- A wooden or plastic utensil for gentle lifting
- Clean towels
- Rubber gloves, if your skin is sensitive
Check your owner’s manual before you begin. Look for instructions about:
- Dishwasher use
- Soaking the basket
- Safe cleaning products
- Nonstick surfaces
- Removable parts
- Warranty limits
Some brands allow the basket and crisper plate to go in the dishwasher. Others recommend hand washing to protect the finish. Even when a part is labeled dishwasher-safe, repeated hot cycles may cause cosmetic wear over time.
Never put the air fryer base, power cord, or heating unit in water.

The safest method for removing burnt grease
This method works well for most removable air fryer baskets and crisper plates. Stop if you see the coating lifting, bubbling, or flaking.
1. Unplug and cool the air fryer
Unplug the appliance and wait until every part is cool enough to handle. Remove the basket and tray from the air fryer base.
Do not clean a hot basket with cold water. A sudden temperature change may warp some parts, and hot grease can cause burns.
2. Remove loose food debris
Shake the basket over a trash can or scrape out loose crumbs with a paper towel. Use a soft brush for food trapped in the holes.
Avoid using a knife, fork, or metal spatula. A sharp edge can scratch the cooking surface.
3. Soak the basket in hot, soapy water
fill a sink or large basin with hot tap water. Add a small amount of grease-cutting dish soap. Place the basket and tray in the water only if the manufacturer permits soaking.
Let the parts soak for 20 to 30 minutes. For thick buildup, extend the soak to about 60 minutes. Keep the water hot by replacing it if it becomes cool.
Do not use boiling water. It is not needed for this task and may damage some plastic handles, seals, or coatings.
4. Make a gentle cleaning paste
Mix:
- 2 tablespoons of baking soda
- 1 teaspoon of dish soap
- Enough water to make a thick paste
Spread the paste over the burnt grease. Leave it on for 10 to 15 minutes.
Baking soda provides mild cleaning power. It is not a magic solvent, so it may not remove every mark at once. Its main benefit is helping lift softened residue without requiring a harsh scouring product.
5. Scrub with a soft tool
Use a soft sponge, nylon brush, or soft toothbrush. Work in small circles and pay extra attention to:
- Basket corners
- Handle joints
- Crisper plate holes
- Raised ridges
- Areas beneath the rim
Use light pressure. If the grease does not move, add more warm, soapy water and let the part soak again. More force can damage the coating.
A wooden or plastic utensil may help lift a thick edge of residue. Keep the utensil flat and do not pry under the coating.
6. Rinse until no cleaner remains
Rinse the basket and tray under warm running water. Check the holes and seams for trapped baking soda or food residue.
Leftover soap can affect food flavor. Residue in the basket holes may also smoke during the next cooking cycle.
7. Dry and inspect the basket
Dry the parts with a clean towel. Then let them air-dry fully before putting them back in the air fryer.
Inspect the surface under bright light. A dark stain may be permanent discoloration rather than removable grease. If the surface is smooth, intact, and free of sticky residue, it may still be usable.
Replace the part if you see:
- Peeling or flaking coating
- Deep scratches
- Blisters or bubbles
- Exposed base metal
- Rust
- A loose or damaged handle
- Grease that keeps smoking after thorough cleaning

What to do when the grease will not come off
If one cleaning cycle fails, identify the type of residue before choosing a stronger approach.
| What you see | Likely cause | Best next step |
|---|---|---|
| Soft, sticky film | Fresh or partly cooked grease | Repeat a warm soapy soak |
| Hard brown crust | Burnt oil and food residue | Use baking soda paste and a nylon brush |
| Black stains with a smooth surface | Discoloration or carbonized residue | Do not keep scraping; inspect the coating |
| Grease in small holes | Oil trapped during cooking | Soak, then use a soft toothbrush |
| Peeling or bubbling finish | Damaged coating | Replace the basket or tray |
| Rust-colored spots | Exposed metal or corrosion | Stop using the part until the manual or manufacturer gives a clear remedy |
Try a second soak
For stubborn grease, repeat the hot-water soak rather than using a harsher chemical. A second 30-minute soak often loosens residue that the first treatment softened but did not remove.
Use a soft toothbrush for the holes
A soft toothbrush can reach the small openings in a crisper plate. Brush from both sides while the part is wet and soapy.
Do not push a stiff brush hard into the holes. This can bend the plate or scrape the finish around the openings.
Use a manufacturer-approved degreaser
Only use a commercial degreaser if the air fryer manual or basket manufacturer says it is safe for the surface. Follow the product label, rinse thoroughly, and keep the cleaner away from the appliance’s electrical base.
Many strong degreasers are made for stainless steel, ovens, or grills. That does not mean they are safe for a coated air fryer basket.
Consider replacement
A replacement basket or crisper plate may be the safest and most practical choice when buildup is bonded to a damaged coating. Contact the manufacturer with the model number. Do not assume that a basket from a different model will fit correctly.

Clean the air fryer base and heating area safely
The removable basket is not the only part that collects grease. Grease can splatter onto the drawer, heating coil, and upper interior.
To clean the base:
- Unplug the air fryer.
- Let it cool completely.
- Turn it upside down only if the manual permits this.
- Wipe the interior with a damp microfiber cloth.
- Use a soft, slightly damp toothbrush around the heating element.
- Wipe away cleaner with a clean damp cloth.
- Dry the area before plugging the appliance in.
Do not spray cleaner directly into the air fryer. Spray or apply it to a cloth instead, and use only a product approved for the surface.
Never immerse the base or allow water to run into the fan, controls, vents, or electrical parts.
If grease on the heating coil smokes during use, unplug the appliance and let it cool. Clean the area again. If smoke continues, contact the manufacturer before using the air fryer.

Cleaning methods to avoid
Several popular cleaning tricks can damage an air fryer basket or create a safety problem.
Do not use steel wool or metal scouring pads
Metal fibers can scratch a nonstick surface. The scratches may trap food and make future cleaning harder.
Do not use oven cleaner unless the manual allows it
Oven cleaner is often very caustic. It may damage nonstick coatings, aluminum, paint, seals, or plastic handles. It can also leave chemical residue if the part is not rinsed correctly.
Do not use bleach
Bleach is not needed to remove burnt grease. It can damage surfaces and create harmful fumes if mixed with other cleaners.
Never mix bleach with vinegar, ammonia, or any other cleaner.
Do not scrape with a knife
A knife may remove a small patch of grease, but it can also cut through the coating. Use a plastic scraper or wooden utensil instead.
Do not run the basket through a cleaning cycle with detergent inside the appliance
An air fryer is not a self-cleaning oven. Do not fill the drawer with water and run the appliance unless the manufacturer specifically designed that model for the process.
Do not heat an empty basket to burn off grease
Heating grease can create smoke and may increase the risk of a kitchen fire. It can also make the residue harder to remove.

How to prevent burnt grease from coming back
Regular cleaning is easier than removing a thick carbon layer. Use these habits:
- Wipe the basket after each use.
- Wash the basket while residue is still warm, but not hot.
- Remove crumbs from the drawer and heating area.
- Do not overfill the basket.
- Use only the amount of oil needed for the recipe.
- Avoid aerosol cooking sprays if the manual warns against them.
- Use parchment made for air fryers only when it is weighed down by food.
- Do not place loose parchment in the basket during preheating.
- Check the basket for peeling or scratches.
- Follow the manual’s temperature and cleaning instructions.
A light film of oil is easier to remove than oil that has been heated again and again. Cleaning after each use also reduces smoke and unwanted odors.
The U.S. Department of Agriculture recommends cleaning food-contact surfaces after use as part of basic food safety practice. Air fryer cleaning also protects the appliance from smoke caused by old grease. See the USDA food safety cleaning guidance.

When should you replace an air fryer basket?
Replace the basket when the cooking surface is no longer intact. A small stain is usually different from physical damage.
A smooth dark mark may be baked-on discoloration. It is more concerning when the area feels sticky, flakes off, bubbles, or exposes metal.
Also replace the basket if:
- Food repeatedly sticks despite proper cleaning
- Rust appears on the cooking surface
- The basket is bent and no longer slides in correctly
- The handle is loose
- The crisper plate does not sit securely
- The coating leaves flakes on food
Do not sand, repaint, or coat the basket at home. These fixes can introduce unsafe materials into food and may interfere with airflow.
If you are unsure, check the owner’s manual or ask the manufacturer for a replacement part. Have the model number and part name ready.

- Start with a hot, soapy soak for 20 to 30 minutes.
- Use baking soda and dish soap for a gentle paste.
- Scrub with a soft sponge or nylon brush.
- Avoid steel wool, knives, bleach, and unapproved oven cleaner.
- Never immerse the air fryer base.
- Smooth stains may be cosmetic; peeling or scratched coating means replacement.
- Clean the basket after each use to prevent grease from hardening.
Frequently asked questions
Can I use vinegar to clean burnt grease from an air fryer basket?
You can use diluted vinegar for some odors or mineral deposits, but it is not the best tool for thick burnt grease. Do not mix vinegar with bleach or other cleaners. For grease, warm water, dish soap, and a mild baking soda paste are usually more suitable.
Can I put a burnt air fryer basket in the dishwasher?
Only if the owner’s manual says the basket is dishwasher-safe. Remove loose grease first, and place the part so it does not rub against sharp items. Hand washing may help preserve the finish even when dishwasher use is allowed.
How do I remove grease from the holes in the basket?
Soak the basket in hot, soapy water, then use a soft toothbrush to brush through the holes from both sides. Rinse well and check that no food or cleaner remains trapped inside.
Why does my air fryer still smoke after I clean the basket?
Smoke may come from grease on the heating element, upper interior, or drawer rather than the basket. Unplug the appliance, let it cool, and wipe the interior with a damp cloth. If smoke continues after cleaning, stop using the appliance and contact the manufacturer.
Is a black air fryer basket ruined?
Not always. A smooth black or brown stain may be permanent discoloration. The basket is more likely damaged if the coating peels, bubbles, flakes, feels rough, or exposes metal. When in doubt, replace the affected part.
Conclusion
The safest way to remove stuck-on burnt grease from an air fryer basket is to soften it first. Use hot tap water, grease-cutting dish soap, a short soak, and a mild baking soda paste. Work with a soft sponge or nylon brush instead of forcing the residue off.
If the coating is scratched, peeling, bubbling, or rusty, cleaning will not restore it. Replace the basket or crisper plate, and always follow the instructions for your specific air fryer model.
