How to Clean an Air Fryer — Step-by-Step Maintenance Guide

An air fryer makes everyday cooking quicker and more convenient, but regular cleaning is essential if you want consistent results from it. Grease, crumbs and food residue can collect around the basket, tray, interior walls and heating area over time. If they are left untouched, they may create unwanted odours, smoke or uneven cooking. The good news is that air fryer cleaning is usually simple when it is done routinely. This guide explains how to clean an air fryer step by step, including the removable parts, interior, heating element and exterior, along with practical maintenance tips.

Why Regular Air Fryer Cleaning Matters

Regular cleaning helps an air fryer work efficiently and keeps yesterday's flavours from affecting today's food. Oil droplets and fine crumbs can gradually build up inside the cooking chamber, especially when foods are breaded, marinated or naturally fatty. That residue may begin to smoke at high temperatures or produce a stale smell. A clean basket also allows hot air to circulate more freely around food. Making air fryer cleaning part of your cooking routine can therefore support better texture, easier maintenance and a cleaner kitchen appliance overall.

What You Need Before Cleaning an Air Fryer

You do not need strong chemicals or specialised equipment for routine cleaning. In fact, gentle tools are usually safer for non-stick surfaces and electrical components. Keep the following items ready:

• Mild liquid dish soap

• Warm water

• A soft sponge or non-abrasive scrub pad

• A microfibre or soft cotton cloth

• A soft-bristled brush or old toothbrush for narrow areas

• Baking soda for stubborn grease, if required

• A dry towel or rack for air-drying removable parts

Avoid steel wool, metal scrubbers, sharp tools and harsh oven cleaners unless the appliance manufacturer specifically permits them.

Step-by-Step: How to Clean an Air Fryer

Step 1: Unplug the Air Fryer and Let It Cool

Always switch off and unplug the air fryer before cleaning. Let the appliance cool completely after cooking, particularly around the basket cavity and heating element. Cleaning a hot unit can cause burns and may damage surfaces if cold water is applied suddenly. Never clean the main body while it is connected to power.

Step 2: Remove the Basket, Tray and Crisper Plate

Take out all removable components, such as the frying basket, drawer, tray or crisper plate. Shake loose crumbs into a bin before washing. Separating these parts makes it easier to reach corners where oil and food particles collect. Check the user manual if you are unsure which pieces are designed to be removed.

Step 3: Soak and Wash Removable Parts

Wash removable parts with warm water, mild dish soap and a soft sponge. If grease is stuck, soak the basket and tray for around 10 to 20 minutes before gently scrubbing them. Avoid abrasive pads that may scratch non-stick coatings. Rinse thoroughly so no soap remains, then place the parts aside to dry. If your appliance has a specially coated basket, such as the Wonderchef's Greenlife 6.5L Air Fryer with its ceramic-coated basket, use only soft, non-abrasive cleaning tools to help protect the cooking surface.

Step 4: Clean Grease from the Air Fryer Interior

Once the appliance is cool, wipe the inside cooking chamber with a soft damp cloth or sponge. Pay attention to corners and the area beneath the basket where crumbs often settle. For greasy spots, use a small amount of mild soapy water on the cloth rather than pouring water directly inside. Wipe again with a clean damp cloth.

Step 5: Wipe the Heating Element Safely

Turn the unit only if the manufacturer's instructions allow easy access to the heating element. Use a dry or lightly damp soft brush or cloth to remove loose residue. Do not saturate the heating coil or electrical area. If grease is heavily baked on, clean gently in stages instead of scraping it with metal tools.

Step 6: Clean the Exterior and Control Panel

Wipe the exterior with a soft damp cloth to remove fingerprints, oil splashes and kitchen dust. For digital air fryers, take extra care around the display and controls so moisture does not enter gaps. A dry microfibre cloth can be used afterwards to remove streaks. Never immerse the main appliance body in water. This is especially relevant for digital models such as the Wonderchef's Neo Pro 4.5L Digital Air Fryer, where the control area should be wiped gently rather than sprayed directly with cleaner.

Step 7: Dry and Reassemble the Air Fryer

Allow the basket, tray and all cleaned surfaces to dry completely before putting the air fryer back together. Trapped moisture can create odours and should not be left near electrical components. Once everything is dry, replace the crisper plate and basket correctly. Store the appliance with the cooking chamber clean and free of crumbs.

How to Deep Clean Stubborn Grease and Odours

Routine washing handles most mess, but occasionally an air fryer develops baked-on grease or lingering smells. For stubborn residue on removable, washable parts, make a mild paste using baking soda and a little water. Apply it to the affected area, leave it briefly, and gently loosen the residue with a soft sponge or brush before rinsing well.

For odours, wash the basket and tray thoroughly and check hidden areas around grooves, rubber feet and corners where grease may remain. Wipe the interior again with a clean damp cloth and let the appliance air-dry with the drawer open.

Avoid filling the air fryer drawer with water and running the appliance to “steam clean” it unless that method is specifically approved by the manufacturer. Electrical appliances should not be exposed to unnecessary moisture. Also avoid highly acidic or strongly scented cleaning products that may leave a residue on food-contact surfaces.

How Often Should You Clean an Air Fryer?

A simple cleaning schedule prevents residue from becoming difficult to remove. The exact frequency depends on what you cook and how often you use the appliance. Greasy or crumb-heavy foods generally require more frequent attention than dry foods.

Common Air Fryer Cleaning Mistakes to Avoid

Even simple cleaning can cause damage if the wrong method is used. Avoid these common mistakes:

1. Cleaning while the appliance is still hot: Heat increases the risk of burns and can make sudden temperature changes harder on coated parts.

2. Immersing the main unit in water: The body contains electrical components and should only be wiped as directed.

3. Using steel wool or metal utensils: Abrasive tools can scratch baskets and damage non-stick coatings.

4. Spraying cleaner directly inside: Apply mild cleaner to a cloth or sponge instead of soaking internal electrical areas.

5. Ignoring the heating area: Grease splatter above the basket can eventually create smoke or smells if it is never checked.

6. Reassembling damp parts: Let all pieces dry fully before use or storage.

Maintenance Tips to Keep Your Air Fryer Performing Well

A few small habits can reduce the need for heavy cleaning later:

• Remove crumbs after each use once the air fryer has cooled.

• Wash greasy baskets and trays soon after cooking so residue does not harden.

• Use liners only when suitable for your model and make sure they do not block essential airflow.

• Avoid overfilling the basket, which can increase splatter and make cooking less even.

• Check the interior and heating element periodically rather than waiting for visible smoke.

• Follow the cleaning and dishwasher guidance in the manual for your specific air fryer.

When cleaning becomes part of the normal cooking routine, maintenance takes only a few minutes and the appliance stays ready for the next meal.

Frequently Asked Questions

1. Can I wash an air fryer basket in the dishwasher?

Many air fryer baskets and removable trays are dishwasher-safe, but not all of them are. The safest approach is to check the product manual or care instructions for your model. Even when dishwasher use is allowed, hand washing with mild soap and a soft sponge may help reduce unnecessary wear on coated surfaces over time.

2. How do I remove baked-on grease from an air fryer?

Soak the removable basket or tray in warm soapy water to soften baked-on grease. Then use a soft sponge or nylon brush to lift the residue gradually. For stubborn patches, a mild baking-soda paste can help. Do not use metal scrapers or aggressive abrasives, as they can damage the cooking surface.

3. Can I use baking soda to clean an air fryer?

Baking soda can be useful on stubborn grease, particularly on removable washable parts. Mix a small amount with water to create a gentle paste, apply it briefly, then wipe or scrub softly and rinse thoroughly. Avoid getting the paste inside electrical areas, vents or components that should not be exposed to water.

4. Why does my air fryer smell even after cleaning?

Lingering smells usually mean grease or food residue is still trapped somewhere, such as around basket grooves, the underside of the crisper plate or the upper cooking chamber. Clean those areas carefully and let the appliance dry with the drawer open. Strong food aromas may also take more than one cleaning cycle to disappear.

5. How often should the heating element be cleaned?

The heating area does not necessarily need a full clean after every meal, but it should be checked regularly for grease splatter and food residue. If you frequently cook fatty foods, inspect it more often. Always unplug the air fryer, let it cool completely and follow the manufacturer's instructions before cleaning around the heating element.

Conclusion

Knowing how to clean an air fryer correctly makes routine maintenance easier and helps keep the appliance pleasant to use. Focus on washing the removable basket and tray, wiping the interior after messy cooking, checking the heating area periodically and keeping moisture away from electrical parts. Gentle cleaning done regularly is usually more effective than aggressive scrubbing after grease has built up. If you use your air fryer frequently, a quick clean after each cooking session and a deeper check from time to time can keep it ready for everyday recipes.
