Every July in Montreal, apartments across Plateau, Griffintown, and Côte-des-Neiges fill with the smell of frites, chicken thighs, and halloumi cooked without turning on the oven. The air fryer has become the go-to summer appliance for apartment dwellers who want fried food without raising indoor temperatures by 5°C. But all that cooking comes at a cost: the basket, tray, and interior walls accumulate a layer of polymerized fat that standard dish soap cannot cut — and in a DCC condo building, ignoring it risks triggering the building's photoelectric smoke detectors at your next cooking session.
This guide covers every air fryer type common in Montreal apartments, the right protocol for each, and the baking soda paste technique that dissolves baked-on grease from diverse cooking cultures — South Asian ghee, Haitian coconut oil, Québécois butter and lard, Middle Eastern za'atar and spice oils — all of which polymerize into hard lacquer coatings at the 180–220°C operating temperatures of modern air fryers.
Why Air Fryer Grease Is Harder to Remove Than Oven Grease
A conventional oven spreads heat slowly over a large cavity. An air fryer concentrates intense circulating heat in a compact space, driving cooking temperatures up faster and baking any fat splatter onto surfaces at higher effective temperatures. Ghee, butter, and coconut oil start to polymerize (cross-link into a hard resin) at around 180°C — exactly the temperature most air fryer recipes call for. After 2–3 cooking sessions without cleaning, the basket develops a sticky amber-coloured film. After 5–6 sessions, that film hardens into a dark brown lacquer that smokes at the start of the next cook cycle.
In a Montreal apartment building with photoelectric smoke detectors — far more common in post-2000 condo buildings (DCC syndicates typically specify them for their sensitivity to slow smouldering fires) than in older triplexes with ionization detectors — this smouldering grease at the start of a cook is enough to trigger a building-wide alarm. Regular cleaning is not optional in DCC buildings.
Know Your Air Fryer Type
The three types of air fryers in Montreal kitchens each require different cleaning access:
Basket-style drawer (Philips, Cosori, Gourmia — the most common type): The food basket slides out of the main unit on a pull-out drawer. The basket has a non-stick coating. The drawer has a separate drip pan underneath. Both components are usually dishwasher-safe, but hand-washing extends non-stick life significantly.
Tray/toaster-style (Ninja Foodi, Instant Vortex): The unit opens like a toaster oven. Removable racks and a crumb tray sit inside. The interior walls are exposed and need direct cleaning. More cleaning access than basket-style; more surfaces to clean.
Rotisserie drum (Ninja Foodi Max, Cosori XL rotisserie): A rotating spit and drum cage sit inside the unit. Fat drips down to a bottom drip tray. The rotisserie spit and drum require disassembly before cleaning.
What You'll Need
- Dish soap (Dawn or Palmolive, from IGA/Maxi/Metro — ~$3)
- Baking soda (Maxi/IGA/Costco — ~$3/kg)
- White vinegar (IGA/Maxi/Metro — ~$2.50/L)
- Soft non-scratch sponge (Canadian Tire or Dollarama — ~$2)
- Soft-bristle brush (bottle brush or pastry brush — Canadian Tire/Dollarama ~$3)
- Microfibre cloths (Canadian Tire/Dollarama — ~$5)
- Toothpick or wooden skewer (for heating element debris)
Do NOT use: steel wool, abrasive scrubbing pads (Scotch-Brite heavy-duty), or any metallic scraper. These permanently damage non-stick coatings in 1–3 uses.
Step-by-Step Cleaning Protocol
After every use (5 minutes)
1. Unplug the air fryer and let it cool completely — minimum 30 minutes. Never immerse a still-warm appliance in water; thermal shock can warp non-stick coatings. 2. Remove the basket (or rack/tray on tray-style units). 3. Wipe the interior walls with a damp microfibre cloth while the residual warmth is still present — grease wipes off more easily when slightly warm (not hot). Do not use water directly on the heating element. 4. Wash the basket and drip pan in warm soapy water. A soft sponge removes fresh grease in 1–2 minutes. Rinse well and air dry completely before reassembling.
Weekly deep clean (15–20 minutes)
1. Remove all removable parts (basket, pan, tray, rotisserie accessories if applicable). 2. Soak removable parts in hot water with 2 tablespoons of dish soap for 10 minutes to loosen accumulated oil. 3. Scrub with a soft-bristle brush — work the brush around the basket mesh holes where grease accumulates. 4. Rinse and set aside to dry. 5. Wipe the interior cavity with a damp cloth — top, sides, bottom. 6. For the door/drawer face, use a damp microfibre cloth and dry immediately.
The Baked-On Grease Protocol (Baking Soda Paste)
When the basket or interior walls have developed a hard brown coating that soap and water won't lift, baking soda paste is the solution:
1. Mix 3 tablespoons of baking soda with just enough water to form a thick paste (peanut butter consistency). 2. Apply the paste directly to the affected area and let it sit for 15–20 minutes. 3. Scrub gently with a soft brush. The mild abrasive action of baking soda combined with its alkaline pH breaks down the polymerized fat layer. 4. Rinse thoroughly. Repeat if needed for very stubborn buildup.
For Montreal's diverse cooking cultures, this protocol handles ghee residue, coconut oil buildup, and lard from Québécois tourtière. A second round rarely needs to exceed 10 minutes.
Cleaning the Heating Element
The heating element sits at the top of the air fryer cavity in basket-style units (above where the basket sits when inserted). It is the most important — and most fragile — component to keep clean.
Never submerge the main unit in water. Never spray water directly onto the heating coil.
After the unit has cooled completely, use a damp microfibre cloth (wrung out so it does not drip) to wipe the heating element coil gently. For debris stuck in the coil (a common result of cooking breaded items like panko chicken), a dry toothpick removes it without damaging the coil.
Montreal hard water (90–150 mg/L CaCO₃) leaves white mineral scale on the heating coil over time if steam from food enters the cavity. A cloth dampened with diluted white vinegar (1:2 vinegar to water) removes calcium scale from the coil — apply, wait 2 minutes, wipe dry with a clean microfibre cloth. Ensure the coil is completely dry before the next use.
Protecting the Non-Stick Coating
Non-stick coating damage is the most common air fryer problem in Montreal shared triplex kitchens where multiple people use the same appliance. Scratched non-stick means the coating releases particles into food and loses its effectiveness.
Rules to protect non-stick: - Always use silicone tongs or wooden utensils inside the basket. - Never cut food while it's still in the basket. - Use only soft sponges — never the abrasive (green) side of a standard Scotch-Brite. - If using cooking spray, use a pump oil sprayer rather than aerosol cans — aerosol lecithin builds up as a sticky residue on non-stick that accelerates coating degradation. - Dishwasher use: while most baskets are labelled dishwasher-safe, the high heat and harsh detergents in dishwashers degrade non-stick faster than hand-washing. Hand-wash with warm soapy water for maximum coating life.
How Often to Clean
| Frequency | What to do | |---|---| | After every use | Quick wipe of interior, wash basket | | Weekly | Full soak and scrub of all removable parts | | Monthly | Baking soda paste for any baked-on buildup; heating element vinegar wipe | | When you notice smoke | Immediate deep clean before next use — do not cook through smoke |
In summer (July–August in Montreal), when air fryers often run daily for apartment cooking, weekly deep cleans are essential to prevent smoke and grease buildup.

Frequently Asked Questions
Q: How do you get burnt grease off an air fryer basket?
A: Baking soda paste is the most effective home remedy for burnt polymerized grease. Mix 3 tablespoons of baking soda with enough water to form a thick paste, apply to the burnt area, and let it sit for 15–20 minutes. Scrub gently with a soft brush. For very stubborn buildup (common with ghee or coconut oil cooked repeatedly at 200°C), a second application after the first rinse usually finishes the job. Never use steel wool — it destroys non-stick coatings permanently.
Q: Can you put an air fryer basket in the dishwasher?
A: Most air fryer baskets are labelled dishwasher-safe, and occasional dishwasher use won't cause immediate damage. However, dishwasher high-heat drying cycles and harsh alkaline detergents degrade non-stick coatings faster than hand-washing. In Montreal, where dishwasher detergents combined with hard water 90–150 mg/L leave calcium residue, hand-washing in warm soapy water with a soft sponge significantly extends basket life. Reserve the dishwasher for occasional heavy cleanups, not daily use.
Q: How do you clean an air fryer heating element?
A: Never submerge the main unit in water and never spray water directly on the coil. Once the unit has fully cooled, wipe the heating element with a damp (not dripping) microfibre cloth. Remove debris from between the coil loops with a dry toothpick. For hard water calcium scale (white mineral deposits) from Montreal tap water, dampen a cloth with diluted white vinegar (1:2 vinegar-to-water), wipe the coil, wait 2 minutes, then dry completely with a clean cloth before the next use.
Q: How often should you clean an air fryer in Montreal?
A: Wipe the interior and wash the basket after every use (5 minutes), do a full soak-and-scrub weekly (15 minutes), and use baking soda paste on any baked-on buildup monthly. In Montreal July–August when air fryers run daily for no-oven summer cooking, a weekly deep clean prevents smoke from triggering building smoke detectors — a real concern in DCC condo buildings with sensitive photoelectric detectors.
Q: Why does my air fryer smoke every time I use it?
A: Smoke during cooking almost always means baked-on grease on the basket, drip pan, or heating element is burning off. Once polymerized fat ignites at the start of a cook cycle, the smoke continues until that residue is removed. In Montreal condo buildings with photoelectric smoke detectors, this can trigger a building alarm. Clean the basket and wipe the interior walls thoroughly, then run the air fryer empty at 180°C for 3 minutes to burn off any residue before your next food cook — with the window open.
Q: Can you use parchment paper in an air fryer to make cleaning easier?
A: Perforated parchment liners (sold at Canadian Tire and on Amazon for ~$8–12/pack) dramatically reduce cleaning time by catching most of the drips before they reach the basket. They must be perforated to maintain airflow — solid parchment paper blocks the circulation that makes air frying work and is a fire risk if it comes in contact with the heating element. Never place parchment in an empty preheating air fryer; the paper can fly up and contact the heating element. Add the parchment after food is placed in the basket, not before.
