Your Bella 4Qt Slim Air Fryer’s EverGood ceramic nonstick coating is designed for easy cleanup, but using harsh tools or chemicals can permanently damage it. This guide walks you through the safe cleaning process, explains the critical rules to follow, and highlights the common mistakes that scratch or degrade the coating so you can keep your air fryer performing like new.
Quick Answer: Always let the air fryer cool completely after use. Only the frying basket and crisping tray are safe to wash in hot, soapy water with a soft cloth or sponge. Wipe the main body with a damp cloth only, and never immerse it. Dry all parts thoroughly before storing to protect the ceramic coating.
Understanding the Cleaning Rules
Keeping your Bella air fryer clean is straightforward once you know its limits. The entire process is built around one core rule: protect the electrical components and the delicate ceramic coating on the removable parts.
Keep the Main Body Dry
The main housing contains the heating element, fan, and digital controls. It is not waterproof. Submerging this part or running it under water will cause immediate electrical damage and create a serious safety hazard. The only safe way to clean the exterior and the cavity where the basket sits is to wipe it down with a damp cloth after unplugging the unit.
Use Only Gentle Cleaners on the Coating
The EverGood ceramic coating on the frying basket and crisping tray is designed to release food with minimal effort, but it requires gentle care. Stick to hot water and mild dish soap. Abrasive scouring pads, powdered cleansers, or harsh chemicals like oven cleaner will scratch and degrade the nonstick surface, making it less effective over time. A soft sponge or cloth is all you need for most cleaning.
Secure the Crisping Tray’s Rubber Tips
Proper maintenance includes a quick check of the four rubber tips on the sides of the crisping tray. These nubs ensure the metal tray fits snugly inside the frying basket. If they come off during washing, simply slide them back onto the plastic tabs. Keeping them in place prevents the tray from rattling during use and, more importantly, stops the metal edges from scratching the basket’s ceramic coating.

Step-by-Step Cleaning Guide
Follow this routine after each use to prevent grease buildup and coating damage. Skipping steps or rushing is how most problems start.
Cool Down First
This is a critical safety step. The basket, tray, and main unit can stay dangerously hot for 30 minutes after cooking. Always unplug the air fryer and let it cool fully before handling parts for cleaning. Cleaning a hot basket with cold water can also cause thermal shock, potentially damaging the ceramic coating.
Washing the Basket and Tray
- Remove the frying basket. Grasp the handle and pull the entire drawer straight out from the main unit.
- Lift out the crisping tray. Insert a finger into the tray’s center hole and lift it up and out of the basket drawer.
- Wash both parts. In the sink, use hot water, a few drops of dish soap, and a soft sponge. For stuck-on food, let the parts soak for 5-10 minutes to loosen debris. Avoid aggressive scrubbing.
- Rinse and dry thoroughly. Rinse with clean water and towel-dry immediately. Pay close attention to drying the basket’s mesh and the tray’s surface to prevent moisture-related issues.
Wiping Down the Exterior
While the removable parts dry, clean the main body. Dampen a soft, non-abrasive cloth with water—a microfiber cloth works perfectly. Wipe down the exterior housing, the touchscreen control panel, and the interior cavity. For stubborn exterior grease, a tiny drop of dish soap on the damp cloth can help; wring the cloth out well to prevent water from dripping into the appliance. Always follow with a dry cloth to remove any remaining moisture.
Common Cleaning Mistakes to Avoid
Protecting your air fryer long-term means avoiding a few key errors. These are the main reasons nonstick coatings fail, appliances begin to smoke, or units stop working prematurely.
Avoid Abrasive Pads and Scourers
Steel wool, metal scouring pads, and rough green scrubbing sponges will scratch the ceramic coating. Once scratched, the nonstick properties are compromised, leading to more food sticking and a cycle of increasingly aggressive cleaning that causes further damage. Always use soft-sided sponges or cloths.
Never Use Harsh Chemicals
Cleaners like oven spray, bleach solutions, ammonia-based products, or other strong solvents are not safe for this appliance. They can chemically break down the ceramic coating, causing it to discolor, become sticky, or flake off. They can also damage the plastic housing and touchscreen. Mild dish soap and water are sufficient for all cleanable surfaces.
Always Dry Completely Before Storage
Never put the air fryer away while any part is damp. Moisture trapped in the basket mesh or on the tray can lead to rust or mildew. Storing the main unit while damp risks electrical corrosion or mold growth inside the housing. Always ensure all parts are clean, completely dry, and the unit is unplugged and cool before storing.
Frequently Asked Questions
Can I put the Bella air fryer basket and tray in the dishwasher?
Hand-washing in hot, soapy water is the only method specified and recommended. Dishwasher detergents can be harsh, and the high heat may compromise the ceramic coating over time. For guaranteed protection of the nonstick surface, hand-washing is the best practice.
How do I clean burnt-on grease or food that won’t come off?
For stubborn residue, let the basket and tray soak in hot, soapy water for 15-20 minutes to soften it. A soft-bristled nylon dish brush can help dislodge particles from the basket mesh without scratching. Never use metal utensils to scrape the coating. For recurring grease issues that cause smoke, see our guide on Bella Air Fryer Smoking? How to Stop Excess Smoke and Grease.
The Bella air fryer touchscreen is sticky from splatter. How do I clean it?
With the unit unplugged and cool, use a very well-wrung damp cloth to gently wipe the touchscreen. Do not spray cleaner directly on the screen, as liquid can seep into the electronics. A slightly damp cloth with a tiny bit of soap can cut through grease, followed immediately by a dry cloth. Avoid abrasive pads or paper towels that can scratch the surface.
What should I do if the main unit gets wet inside?
If water splashes into the main housing, unplug the air fryer immediately. Use a dry cloth to soak up as much moisture as possible, then let the unit air-dry thoroughly for at least 24-48 hours in a warm, dry place before attempting to use it again. Do not use a heater or hair dryer to speed up the process. If the Bella air fryer won’t turn on after getting wet, start with the checks in Bella 4Qt Slim Air Fryer Won’t Turn On? Check This First.
Why is it important to check the rubber tips on the crisping tray?
The four rubber tips prevent the metal crisping tray from scratching the ceramic coating inside the frying basket. They also ensure a secure fit, which stops the tray from vibrating or shifting during cooking. This leads to better air circulation and more even cooking results.
My Bella’s ceramic coating looks stained. Is it ruined?
Light staining from oils or spices is often cosmetic and doesn’t affect performance. You can try gently wiping the area with a paste of baking soda and water using a soft cloth, then rinsing thoroughly. As long as the surface remains smooth and food releases easily, the coating is still functional.
