How to Keep Your COSORI Air Fryer Clean and Running Well

What COSORI air fryers are and how to care for them

COSORI air fryers are countertop appliances that circulate hot air to cook food quickly, and they need regular cleaning to work properly and last longer. The brand makes several models—basket-style, oven-style, and dual-basket versions—but they all share the same basic maintenance needs: a clean basket, a clear heating element, and a dry interior. Unlike a traditional oven, an air fryer's heating coil sits close to the food, so grease and food particles build up faster and can affect cooking performance if left unchecked.

Caring for your COSORI air fryer is straightforward because most parts come apart for washing. The basket, tray, and racks are dishwasher-safe on the top rack in most models, though hand-washing extends their life. The heating chamber itself never needs to be submerged—you clean it with a damp cloth while the unit is unplugged and cool. Understanding these differences between what can be washed and what must be wiped down prevents damage and keeps your air fryer functioning as designed.

Key Takeaways

• Empty and wipe the basket after every use, and wash it thoroughly once a week to prevent grease buildup that affects cooking.
• The heating element and interior walls need only a damp cloth wipe when cool and unplugged—never soak or spray water directly on the heating coil.
• Line your basket with parchment paper or a silicone mat to catch drips and reduce cleaning time between uses.
• Odors inside the air fryer usually come from old grease; running the unit empty at 400°F for 3 to 5 minutes after cleaning helps clear them.
• Check your specific COSORI model's manual for which parts are dishwasher-safe, as some accessories vary by model.

Cleaning the basket and tray after each use

The basket is where most food contact happens, so it collects grease and crumbs that can smoke or burn on the next use. After the air fryer cools for 5 to 10 minutes, remove the basket and tap out loose crumbs into the trash. Wipe the inside surfaces with a dry paper towel or soft cloth to remove residue while it is still warm—warm grease wipes away more easily than cold grease.

For a deeper clean, wash the basket under warm running water with a soft sponge and dish soap. Avoid steel wool or abrasive scrubbers, which can scratch the non-stick coating. Pay special attention to the corners and the underside of the basket, where grease pools. Rinse thoroughly and dry completely before putting it back in the unit. If you wash the basket in the dishwasher, place it on the top rack and use a gentle cycle; the high heat of the bottom rack can damage the coating over time.

The tray or drip pan that sits below the basket catches oil and food particles. Remove it after every use, empty any liquid into the sink, and wipe it with a paper towel. Once a week, wash it with soap and water. If grease has hardened, soak it in warm soapy water for 10 to 15 minutes before scrubbing.

Wiping down the heating element and interior walls

The heating coil sits at the top of the air fryer chamber and can accumulate grease splatter over time. Never spray water directly on it or submerge it. Instead, unplug the unit and let it cool completely. Dip a soft cloth or non-abrasive sponge in warm water, wring it out so it is barely damp, and gently wipe the coil and the interior walls. Work slowly around the heating element to avoid pushing debris into crevices.

If grease has hardened on the coil, dampen the cloth with a mixture of equal parts white vinegar and water. The acidity helps dissolve buildup without requiring scrubbing. Wipe once or twice, then follow with a cloth dampened in plain water to rinse away vinegar residue. Dry the interior with a clean cloth before plugging the unit back in. This monthly maintenance prevents smoke during cooking and keeps the air fryer smelling fresh.

Removing odors from inside the chamber

Air fryers can develop stale or burnt smells when grease oxidizes inside the chamber. After you have cleaned the basket and wiped the interior, run the unit empty at 400°F for 3 to 5 minutes with the door or basket area open if your model allows it. This heat helps evaporate residual moisture and odor-causing compounds. Let it cool, then wipe the interior one more time with a damp cloth.

If the smell persists, place a small bowl of white vinegar or baking soda inside the basket and run the unit at 350°F for 5 minutes. Both substances absorb odors naturally. Remove the bowl, let the air fryer cool, and wipe the interior again. Avoid commercial air fresheners or sprays inside the chamber, as they can leave residue on the heating element or be inhaled during cooking.

Using liners and accessories to reduce cleaning time

Parchment paper liners and silicone mats designed for air fryers catch grease and food particles before they touch the basket. Place a liner on the bottom of the basket before adding food. These liners are reusable if you wash and dry them after each use, or disposable if you prefer. They reduce the amount of scrubbing needed and protect the non-stick coating from wear.

Some COSORI models come with or support metal racks or dividers that let you cook multiple foods at once. These accessories are usually dishwasher-safe, but check your manual. If hand-washing, treat them the same way as the basket: warm soapy water, soft sponge, and thorough drying. Do not use metal utensils to scrape them, as this damages the coating.

Storing your air fryer to keep it fresh between uses

Store your COSORI air fryer in a cool, dry place away from direct sunlight and moisture. If you store it in a cabinet or closet, make sure the interior is completely dry first—any trapped moisture can cause mold or rust. Leave the basket out of the unit during storage so air can circulate inside. If you live in a humid climate, place a small packet of silica gel or uncooked rice inside the chamber to absorb moisture.

Before using the air fryer after a long storage period, wipe the interior with a damp cloth and run it empty at 350°F for 5 minutes to clear any dust or stale air. This is especially important if the unit has been stored in a garage or basement.

Troubleshooting common COSORI air fryer problems

If your COSORI air fryer is not heating evenly or cooking unevenly, the heating element may be partially blocked by grease or debris. Unplug the unit, let it cool, and inspect the coil with a flashlight. Wipe away any visible buildup with a damp cloth. Uneven cooking can also happen if you overcrowd the basket—food needs space for air to circulate. Arrange items in a single layer and avoid stacking.

If the basket is sticking or hard to remove, grease may have dried around the edges. Soak the connection points in warm soapy water for a few minutes, then gently work the basket free. Do not force it, as this can damage the locking mechanism. If the non-stick coating is peeling or flaking, stop using the basket and contact COSORI customer service for a replacement, as flaking coating should not be ingested.

Frequently Asked Questions

Can I put my COSORI air fryer basket in the dishwasher?

Most COSORI baskets are dishwasher-safe on the top rack, but check your specific model's manual because some older or specialty models may differ. Hand-washing with a soft sponge extends the life of the non-stick coating. If you use the dishwasher, avoid the bottom rack and high-heat drying cycles.

What should I do if my air fryer smells like burning plastic?

A plastic smell during the first few uses is normal and fades after 2 to 3 uses as the coating cures. Run the unit empty at 400°F for 5 to 10 minutes in a well-ventilated area. If the smell persists after several uses or returns later, unplug the unit and inspect the heating element and interior for debris or damage, then contact COSORI support.

How often should I deep clean my COSORI air fryer?

Wipe the basket and tray after every use, and wash them thoroughly once a week. Clean the heating element and interior walls with a damp cloth once a month, or more often if you cook greasy foods frequently. A full deep clean—including soaking accessories and running the empty unit—is recommended every three months.

Is it safe to use cooking spray in my COSORI air fryer?

Aerosol cooking sprays can build up on the heating element and basket over time, causing smoke and affecting performance. Use a light brush or your fingers to coat food with a small amount of oil before placing it in the basket, or use parchment paper liners to reduce sticking without spray.

What if water drips from the bottom of my air fryer during cooking?

Water or grease leaking from the bottom usually means the drip tray is full or not seated properly. Remove the basket, check that the tray is pushed all the way in and level, and empty any accumulated liquid. If leaking continues, the tray may be cracked—contact COSORI for a replacement part.
