Basic Cleaning and Maintenance
To keep your Cosori air fryer functioning optimally, regular cleaning is crucial. Start by unplugging the device and allowing it to cool completely. Remove the basket and accessories, and wash them with warm, soapy water. For stubborn grease or food residue, soak the parts in warm soapy water for 10-15 minutes before scrubbing gently with a non-abrasive sponge. Dry thoroughly before reassembling.
In addition, wipe the interior of the main unit with a damp cloth. Avoid using harsh chemicals or abrasive scrubbers that could damage the non-stick coating or electronic components. Regularly check the air vents and fan area to ensure there’s no dust or debris blocking airflow, which can cause overheating or uneven cooking.
Tip: For easier cleanup, consider using disposable liners, but always ensure they are compatible and used correctly to prevent fires or damage.

Replacing Accessories and Preventative Care
Using compatible accessories, like the ALJ 3PCS Air Fryer Oven Mesh Rack, can enhance your cooking experience and help with airflow and crispiness. Always ensure accessories are food-grade and dishwasher safe for easy cleaning.
Prevent issues by avoiding overfilling the basket, which can lead to uneven cooking or damage. Regularly inspect the heating element and fan for debris or residue, and clean as needed. Proper storage of accessories when not in use will prolong their lifespan.
Tip: Avoid using metal utensils that can scratch surfaces, and never operate the air fryer without proper accessories or liners in place when needed for specific recipes.
Safety Tips and Precautions
Always unplug the air fryer before cleaning or performing maintenance. Use only recommended accessories and liners to prevent fires or damage. When cleaning, avoid immersing the main unit in water—wipe with a damp cloth instead.
Ensure the power cord and plug are in good condition. Keep the device on a stable, heat-resistant surface, away from water and combustible materials. During operation, do not leave the appliance unattended.
Warning: Never place liners or accessories in the basket during preheating, as this can cause fire hazards. Always follow the manufacturer’s safety guidelines for safe use.
Extending Your Air Fryer’s Lifespan
Routine maintenance, including regular cleaning and checking for wear and tear, will extend your Cosori air fryer’s lifespan. Use the correct accessories and liners to prevent scratches and residue buildup that could impair performance.
Store the appliance in a dry, dust-free environment when not in use. Avoid abrupt temperature changes and handle the device carefully to prevent damage to internal components. Periodic inspection of the power cord and plug can also prevent electrical issues.
Tip: Follow manufacturer-recommended cleaning frequency and avoid using abrasive cleaners or metal tools that can damage surfaces.
