How to Clean Cosori Pro II 5.8Qt Air Fryer (Non-Stick Basket Care)

The short answer: To clean your Cosori Pro II 5.8Qt air fryer, first unplug and let it cool completely. Then hand wash the non-stick basket and crisper plate in warm soapy water with a soft sponge. For stuck-on food, soak the basket in hot water and dish soap for 10-15 minutes. Wipe the interior with a damp cloth, and never use abrasive cleaners or metal utensils. The basket is dishwasher safe, but hand washing is gentler on the non-stick coating.

Why Proper Cleaning Matters

The Cosori Pro II is a popular air fryer known for its large 5.8Qt capacity and easy-to-use controls. But like any kitchen appliance, it needs regular cleaning to keep it working well and to keep your food tasting great. A clean air fryer also reduces the risk of smoke and odors during cooking. The non-stick basket is designed to release food easily, but it can wear down if you don’t care for it properly. Here’s how to keep it in top shape.

Step-by-Step Cleaning Routine

1. Unplug and cool down. Always unplug the air fryer and wait for it to cool completely before cleaning. This prevents burns and avoids damaging the coating with thermal shock.

2. Remove and wash the basket and crisper plate. Take out the basket and the crisper plate (the removable tray inside). Both are non-stick. Wash them in warm, soapy water using a soft sponge or cloth. Avoid steel wool or abrasive pads that can scratch the surface. If there is stubborn grease, let them soak for 10-15 minutes in hot water with a drop of dish soap.

3. Clean the interior. Wipe the inside of the air fryer with a damp cloth or sponge. Do not submerge the main unit in water. For any residue on the heating coil or fan, use a soft brush to gently dislodge crumbs. You can also wipe with a dry paper towel.

4. Dry and reassemble. Dry all parts completely before putting them back. Moisture can cause rust or affect the non-stick surface.

Dealing with Stuck-On Food and Grease

Sometimes food gets baked on, especially if you cook sticky marinades or cheese. Instead of scrubbing harshly, try these tricks:

• Baking soda paste: Mix 3 parts baking soda with 1 part water to form a paste. Apply to stubborn spots, let sit for 10 minutes, then wipe off with a soft sponge.
• White vinegar solution: Spray a mixture of equal parts white vinegar and water on greasy residue. Let it sit briefly, then wipe clean. This helps break down grease without damaging the non-stick coating.
• Soak in hot water: Fill the basket with hot water and a squirt of dish soap, and let it sit for 15-20 minutes. The grease will loosen, making it easy to wipe away.

Avoid using metal utensils to scrape off food. Instead, use a silicone spatula or a soft brush.

Daily Maintenance and Long-Term Care

To make cleaning easier, follow these habits:

• Wipe after each use: Once the basket is cool, give it a quick wipe with a paper towel to remove oil and crumbs. This prevents buildup.
• Use parchment paper or a liner: You can place a perforated parchment liner at the bottom of the basket to catch drips. Make sure it doesn’t block airflow.
• Don’t overcrowd: Overloading the basket can cause food to stick and make cleaning harder.
• Check the coil: Once a month, inspect the heating coil and fan for any food particles. Use a soft brush to gently clean them.

Dishwasher Safety: Yes, But With Caution

The Cosori Pro II basket and crisper plate are officially dishwasher safe. If you prefer the convenience, you can place them on the top rack of your dishwasher. However, repeated dishwasher cycles can slowly wear down the non-stick coating over time. For this reason, many users choose to hand wash to extend the life of the basket. Whichever method you use, make sure they are fully dry before storing.

What Fits in the 5.8Qt Basket

The 5.8Qt capacity is one of the main reasons buyers choose the Pro II. In practice, that volume translates to roughly 3 to 4 pounds of chicken wings, a whole small chicken of around 3 to 4 pounds, or enough fries for a family of four. The basket is square with rounded corners, which gives it more usable floor area than a round basket of the same quoted capacity. That shape matters for flat items: two or three salmon fillets, four burger patties, or a small pizza can sit side by side without overlapping.

For cleaning, the practical takeaway is that larger loads mean more oil and crumb contact across the entire basket floor, not just the center. If you regularly cook full batches of wings or breaded items, plan on a full soak rather than a quick rinse. Single servings of toast or a handful of vegetables usually need nothing more than a warm soapy wash and a wipe.

Keep in mind that the crisper plate sits slightly above the basket floor. Grease and small crumbs collect in the gap beneath it. Many owners report that this hidden layer is the most common source of lingering smells, so lift the plate out every time rather than washing the basket as a single unit.

Common Mistakes That Damage the Coating

Most non-stick failures on this model trace back to a handful of avoidable habits. Watch for these:

• Cutting food in the basket: Slicing chicken or pizza directly on the non-stick surface leaves permanent score marks. Move food to a board first.
• Stacking wet parts: Putting the basket and crisper plate away while still damp traps moisture and can lead to odor or surface spotting.
• Using aerosol cooking spray: Many spray oils contain lecithin and other additives that bake into a sticky brown film which is very hard to remove. Brush or wipe on a thin layer of regular oil instead.
• Cleaning the coil with a wet cloth: Water near the heating element and fan is a safety risk. Use a dry soft brush, and only wipe the surrounding housing with a barely damp cloth.
• Ignoring the outer housing: Grease film builds up on the exterior and around the vents. A quick wipe with a damp cloth keeps the appliance from looking tired and prevents sticky residue from transferring to your hands.
• Scraping with knives or forks: Even light pressure with metal edges removes the coating in flakes. Silicone, wood, or plastic tools only.

If the coating has already begun to flake or peel, replacement baskets are available from the manufacturer and from third-party sellers. A peeling basket is a food safety concern, not just a cosmetic one, so replace it rather than continuing to cook on a damaged surface.

When to Replace the Basket or the Air Fryer

Non-stick coatings do not last forever, even with careful hand washing. Consider replacement or an upgrade when you notice any of the following:

• Visible flaking or peeling: Bits of coating in your food are a clear sign the basket is past its useful life.
• Persistent sticking despite proper cleaning and oiling: Once the release surface is gone, everyday cooking becomes frustrating and cleanup takes far longer.
• Lingering odors after a deep clean: If the smell of fish, garlic, or burnt grease survives soaking and a lemon deodorizing run, residue has likely worked into areas you cannot reach.
• Uneven cooking or weak airflow: This usually points to a fan or heating issue in the main unit rather than the basket. If the basket is fine but results are inconsistent, the appliance itself may be nearing the end of its service life.
• Rust spots on the crisper plate: Small rust points often spread and can affect the taste of food.

A replacement basket is the budget-friendly route if the main unit still heats and circulates air well. Replacing the whole appliance makes more sense if you are also unhappy with capacity, noise, or cooking performance.

Frequently Asked Questions

Can I use abrasive cleaners on the basket?

No. Avoid harsh scouring pads, steel wool, or abrasive cleaners. They will scratch the non-stick finish, making it easier for food to stick and shortening its lifespan.

How do I remove the smell of fish or garlic from the air fryer?

After cleaning, wipe the interior with a mixture of lemon juice and water, or place a bowl of water with a few lemon slices inside and run the air fryer at 300°F for 5 minutes. This deodorizes naturally.

Is it safe to clean the air fryer while it’s still warm?

No, always wait for it to cool completely. Sudden temperature changes can warp the metal or damage the non-stick coating, and you risk burning yourself.

Remember, proper care ensures your Cosori Pro II stays in great condition for years. Happy cooking!
