How To Clean Bottom Tray Of Air Fryer | No More Grease

You open the air fryer after a week of crispy chicken wings and roasted vegetables, and there it is: the bottom tray coated with a layer of baked-on grease that looks more like industrial glue than residual oil. It’s the part nobody talks about when they rave about air fryer convenience.

The good news is that cleaning that tray doesn’t require harsh chemicals or elbow grease that leaves your arms sore. With the right technique and a few household staples, you can keep the bottom tray looking like new and prevent that burnt-grease smell from ruining your next batch of fries.

Why the Bottom Tray Gets So Grimy

The bottom tray sits directly below the basket, catching every drip of fat, marinade, and breadcrumb that falls during cooking. High heat carbonizes those drippings over time, turning them into a dark, sticky crust that smoking releases on subsequent uses.

Most people only wash the basket and assume the bottom tray stays clean because it’s not directly in contact with food. But grease splatters and aerosolized oil land on it with every batch. Experts from Good Housekeeping recommend cleaning the bottom tray after every use to prevent carbonized buildup that can affect food taste.

Skipping that routine wipe-down means the residue hardens, making later cleanings much harder. A quick post-cooking wipe while the tray is still warm (but safe to touch) cuts the workload in half.

The Best Cleaning Method Step by Step

Here’s the routine that keeps your bottom tray in top shape without damaging the non-stick coating. Gather a soft sponge, mild dish soap, and a towel before you start.

• Unplug and cool completely. Never attempt to clean any part of the air fryer while it’s still plugged in or hot. Wait until the appliance reaches room temperature.
• Remove the tray and rinse. Take the bottom tray out of the unit and rinse it under warm running water to loosen loose crumbs and surface grease.
• Hand wash with warm soapy water. Use a soft sponge and a squirt of mild dish soap. Scrub gently in circular motions, focusing on the corners where grease hides.
• Rinse and dry completely. Rinse off all soap residue, then dry the tray with a dish towel or let it air-dry upright. Moisture left on the tray can promote rust on certain metals.
• Wipe the interior chamber. With a damp cloth, wipe the inside of the air fryer base where the tray sits. Buildup there contributes to smoke.

Follow these steps after every few uses, and you’ll rarely need a deep clean. For quick touch-ups, a paper towel wipe done while the tray is still warm but not hot removes loose grease before a full wash.

Tools and Supplies You’ll Need

You don’t need a cabinet full of specialty cleaners. Most supplies are already in your kitchen. Here’s what works best for different situations.

Remember to always unplug and cool completely before handling any tools or supplies inside the unit. Safety comes first, even with a non-stick tray.

Common Mistakes to Avoid

Even seasoned cooks make errors that shorten the life of their air fryer tray. Avoid these pitfalls to keep cleaning easy and the coating intact.

1. Using abrasive scrubbers. Steel wool, scouring pads, or rough brushes scratch the non-stick surface, making future cleaning harder and potentially flaking coating into food.
2. Submerging the main base. Only the removable basket and tray are washable. Never put the main unit with the heating element in water — it can cause electrical damage and safety hazards.
3. Skipping drying before storage. A wet tray placed back into the air fryer can develop rust or harbor bacteria. Always dry completely before reassembling.
4. Letting grease build up for weeks. Carbonized grease smokes during cooking and transfers a bitter flavor to food. Cleaning after every few uses prevents this.
5. Using harsh chemical oven cleaners. Those chemicals are too strong for non-stick coatings and can leave toxic residues. Stick to mild dish soap or baking soda.

If your tray already has scratches, consider replacing it to avoid non-stick particles in your food. Many brands sell replacement trays for under $20.

Deep Cleaning for Stubborn Grease

When the regular wash isn’t enough — you see blackened patches or a gummy film that won’t budge — it’s time for a deep clean. These methods come from consumer testing and professional cleaning advice.

The soak-and-scrub method works for most cases. Fill your sink or a bowl with very hot water and add a squirt of degreasing dish soap. Submerge the bottom tray and let it soak for 10–15 minutes. The heat and soap loosen the carbonized layer, which then slides off with light scrubbing from a soft sponge.

For truly stubborn spots, make a paste of baking soda and water (roughly 3 tablespoons baking soda to 1 tablespoon water). Apply it to the residue, let it sit for five minutes, then scrub gently. The Kitchn’s side-by-side test also found that a baking soda and hydrogen peroxide paste (let it sit 15 minutes) works on burnt-on patches that soap alone can’t touch.

America’s Test Kitchen notes that many trays are labeled dishwasher-safe but hand wash is often recommended to preserve the non-stick coating. High dishwasher heat and harsh detergents can degrade the coating over time. If you do use the dishwasher, place the tray on the top rack and skip the heated dry cycle.

After any deep clean, rinse thoroughly and dry completely before reassembling. A final wipe of the interior chamber with a damp cloth ensures no loosened debris remains inside.

The Bottom Line

Keeping the bottom tray clean comes down to consistency: wipe it after every use, hand wash with mild soap and a soft sponge, and treat stubborn buildup with a short soak or baking soda paste. Avoid abrasive tools and never submerge the main unit. These habits prevent smoke, preserve non-stick coating, and keep your food tasting fresh.

If your air fryer has a removable bottom tray, check your owner’s manual for specific cleaning instructions — some models have dishwasher-safe parts, but hand washing always extends the non-stick life. For liners, a round of parchment paper sized to fit the tray will catch drips and cut cleanup time in half.
