The range hood is the hardest-working — and most neglected — appliance in a Montreal kitchen. Every time you sauté onions, fry plantains, or simmer a Sunday sauce, the hood traps airborne grease droplets, moisture, and cooking vapour before they can coat your ceiling and upper walls. Over months of neglect, that trapped grease polymerizes into a sticky, amber-coloured layer that ordinary dish soap will not easily remove. In a city with some of Canada's most diverse cooking cultures and some of its oldest kitchen stock, keeping your range hood clean is not optional — it is a fire-prevention measure.
This guide covers every Montreal scenario: homes with traditional under-cabinet or canopy range hoods, apartments with over-the-range microwaves that double as ventilation, and the thousands of pre-war triplexes in Plateau, Rosemont, NDG, and HoMa that were built before range hoods existed at all.

Does Your Montreal Kitchen Even Have a Range Hood?
Montreal's distinctive housing stock creates three very different kitchen ventilation situations.
Pre-war triplexes (1890s–1950s): The kitchens in most NDG, Plateau, Villeray, and Hochelaga triplexes were designed around wood or coal stoves with a metal stovepipe going directly through the wall. When gas stoves replaced solid-fuel ranges in the 1940s–1960s, most of these kitchens were never retrofitted with ventilation hoods. Cooking grease vapour rises straight to the ceiling, coats the upper walls, and stains the underside of overhead cabinets. If your ceiling near the stove has a yellow-to-brown tinge, or if the undersides of your upper cabinets feel tacky to the touch, this is your situation — and a dedicated section near the end of this guide addresses it.
Post-war rental buildings (1960s–1990s): Most Côte-des-Neiges, Ahuntsic, and Saint-Laurent apartment buildings installed recirculating exhaust fans — no external duct, just a fan unit with a charcoal filter that cleans and returns air to the kitchen. These are the compact flat fan units mounted directly above the stove with an integrated light, extremely common in 1970s–1990s rental stock.
Modern condos (2000s–present): Griffintown, Plateau Mile-End, and new South Shore builds almost always have a ducted range hood that vents through the exterior wall or through the building's shared exhaust shaft.

Types of Range Hood Filters
Knowing your filter type determines your cleaning approach.
Mesh and baffle grease filters (ducted hoods and most under-cabinet hoods): Made of layered aluminum mesh or stainless steel baffle plates, these catch grease droplets mechanically. They are fully washable and must be cleaned on a regular schedule. Clean them monthly if you cook every day; every six to eight weeks for more moderate cooking.
Charcoal and carbon filters (recirculating hoods only): These absorb odours and lighter cooking vapours, but they cannot be washed. Once saturated — typically every three to six months — they must be replaced. Check your hood's model number; Canadian Tire, Home Depot, and Rona stock common replacement sizes for $15–30.
Combined filter systems: Some recirculating models have both a metal mesh pre-filter (washable) and a charcoal layer behind it. The mesh gets cleaned on a regular schedule; the charcoal layer gets replaced.

Step-by-Step Cleaning Protocol
What You'll Need
- Dish soap (Dawn or Palmolive — use the standard degreasing formulas)
- Baking soda
- White vinegar (IGA, Maxi, or Dollarama, available in 4 L bottles)
- Microfibre cloths
- Non-scratch nylon scrub brush or sponge (never steel wool on aluminum)
- Rubber gloves
- A large bin, plugged sink, or bathtub for soaking
- Optional: Simple Green Cleaner/Degreaser (Canadian Tire, approximately $12 for 2 L) or Zep Heavy-Duty Degreaser (Home Depot, approximately $15 for 1 L)
Step 1 — Turn Off and Unplug
Always turn the range hood off and, if possible, unplug it or flip its dedicated circuit breaker before cleaning. This is essential before wiping fan blades or the interior chamber near any electrical components.
Step 2 — Wipe the Exterior Surface
Wipe the outside of the hood with a damp microfibre cloth and a few drops of dish soap. For stainless steel hoods: dry immediately after wiping and buff with a clean dry cloth following the steel grain direction — always parallel strokes, never circular. Montreal's hard water (90–150 mg/L calcium) leaves white mineral spots on stainless steel if water is allowed to evaporate naturally; buffing dry immediately prevents this.
Step 3 — Remove the Grease Filter
Most mesh and baffle filters slide out or unlock by pressing a tab on one side. They are held by two clips or a rail system. Remove them over folded newspaper to catch grease drips — they may drip if they have not been cleaned in several months.
Step 4 — Soak and Scrub the Filter
For light to moderate grease buildup: Fill your sink or a basin with the hottest water your tap provides, add two to three tablespoons of dish soap, and submerge the filter. Soak for ten to twenty minutes. Scrub with a nylon brush and rinse thoroughly.
For heavy polymerized grease buildup: Place the filter in your sink. Sprinkle three to four tablespoons of baking soda directly over the greasy surfaces. Slowly pour a full kettle of just-boiled water over the filter. The alkaline baking soda combined with boiling heat breaks down polymerized fats effectively. Let it sit for five to ten minutes, scrub with a nylon brush, rinse, and repeat if needed.
Dishwasher method: Many aluminum mesh filters are dishwasher-safe. Run them on the hottest cycle with a full pod or powdered detergent (not liquid gel, which can leave residue). Confirm dishwasher compatibility in your hood's manual — some cheaper aluminum filters warp under dishwasher heat.
Step 5 — Clean the Interior Chamber and Fan Blades
With the filter removed, wipe the interior walls and ceiling of the hood with a cloth dampened with diluted dish soap or Simple Green (diluted 1:10 with water). For stubborn grease on interior surfaces, apply a paste of baking soda mixed with a few drops of dish soap, leave it for five minutes, then scrub and wipe clean. On models where the fan blades are accessible (common in recirculating hoods), carefully wipe each blade — they accumulate grease on their undersides. Never spray liquid directly into the fan motor housing.
Step 6 — Reassemble and Check the Charcoal Filter
Reinstall the clean mesh filter. While the hood is disassembled, check the charcoal filter if your model has one — if it has been more than four months since the last replacement, swap it now. Replacement charcoal filters run $15–30 at Canadian Tire, Home Depot, or from the range hood manufacturer.

Montreal Hard Water and Stainless Steel Hoods
Montreal tap water delivers 90–150 mg/L of calcium carbonate — moderately hard by national standards. When water evaporates off a stainless steel range hood, it leaves a white calcium film that dish soap cannot remove, because soap dissolves grease, not mineral scale. For calcium deposits: dampen a microfibre cloth with undiluted white vinegar and press it against the affected area for three to five minutes. The acetic acid dissolves calcium carbonate. Rinse with a clean damp cloth, then buff the surface completely dry following the steel grain direction. Finish by applying a very thin film of mineral oil (available at Jean Coutu or Pharmaprix for approximately $6) with a dry cloth — this conditions the steel and creates a light barrier against future water spots and fingerprints.

Grease Fire Prevention: The Montreal Context
Clogged, grease-saturated range hood filters are one of the leading causes of residential kitchen fires. When a filter becomes saturated with polymerized grease, a momentary flare-up at the stove — a high-heat oil splatter, a brief pan fire — can ignite the filter directly. In pre-war triplexes without any range hood, cooking grease accumulates on the ceiling and the underside of upper cabinets, creating an even more dangerous surface if a flame reaches that level. Montreal's dense pre-war housing stock in the Plateau, Rosemont, NDG, and HoMa makes this a genuine local risk. Regular filter cleaning is one of the most effective fire-prevention steps available to Montreal renters and homeowners. If you have experienced a kitchen fire or a major smoke event, see our full [Kitchen Grease Fire Cleanup Guide](/en/blog/how-to-clean-up-after-kitchen-grease-fire-montreal-apartment) for the post-event protocol.

TAL and DCC: Who Is Responsible for Range Hood Maintenance?
Tenants (TAL context): Filter cleaning, light bulb replacement, and routine wiping of the hood's exterior and interior surfaces are tenant responsibilities — these fall under the obligation to maintain the dwelling in clean condition. If the fan motor stops working or the hood unit needs replacing due to normal wear, that is a landlord obligation under Article 1854 of the Quebec Civil Code (maintaining the dwelling in habitable condition). Document any appliance failure in a written notice to your landlord and keep a copy.
Condo owners (DCC context): The range hood unit inside your unit is your responsibility to maintain and clean. If your hood vents into the building's shared exhaust shaft, any duct cleaning or modification inside that shaft requires board approval and typically a licensed contractor — never block or modify a shared building exhaust connection without DCC approval.

The Pre-War Triplex: No Range Hood Protocol
If your Montreal kitchen has no range hood at all — common in pre-war triplexes in Plateau, HoMa, Villeray, and NDG — here is how to manage cooking grease and odours:
1. Cook with windows open whenever possible. Even without a fan, cross-ventilation removes a large proportion of cooking vapour before it can settle on surfaces. 2. Use a splatter screen over frying pans to reduce airborne grease droplets at the source. 3. Clean ceiling and upper wall surfaces quarterly, or monthly if you cook daily with high-heat oils. See our [Kitchen Deep-Clean Guide](/en/blog/how-to-deep-clean-a-kitchen-montreal) and [Walls and Baseboards Guide](/en/blog/how-to-clean-walls-baseboards-montreal) for polymerized grease removal protocols on plaster and painted surfaces. 4. Consider a portable countertop air purifier with HEPA plus activated carbon filter for your kitchen (Levoit, Coway, or Dyson models are available at Costco, Best Buy, or Amazon CA for $80–250). 5. Ask your landlord about an over-the-range recirculating microwave — most models cost under $350 at Rona or Home Depot and require no external ducting. If the kitchen currently has no ventilation device at all, the landlord may have an obligation to provide basic exhaust under Quebec building code.

Frequently Asked Questions
Q: Can I put my range hood filter in the dishwasher?
A: Most aluminum mesh and stainless steel baffle filters are dishwasher-safe — run them on the hottest cycle with a full pod or powdered detergent (avoid liquid gel, which can leave residue on porous aluminum). Confirm dishwasher compatibility in your range hood's manual, as some cheaper aluminum filters warp at dishwasher temperatures. Never put charcoal or carbon filters in the dishwasher — they absorb water and break down; charcoal filters must be replaced, not washed.
Q: How often should I clean my range hood filter in Montreal?
A: The right interval depends on how and what you cook. Daily cooking with high-heat oils — frying plantains, making a roux, preparing a Sunday tomato sauce — warrants monthly filter cleaning. Light or occasional cooking (a few times per week, mostly boiling or low-heat methods) allows six to eight weeks between cleanings. The best guide is a quick visual check: if you see a dark amber or brown coating on the mesh, or if the filter feels sticky through a gloved finger, it is time to clean. For recirculating hoods with charcoal filters, replace the charcoal every three to six months regardless of how the mesh looks.
Q: My range hood grease filter is completely black with polymerized grease — can it be saved?
A: Yes, in most cases. The baking soda plus boiling water method is the most effective non-toxic approach for polymerized fat. Place the filter in your sink, sprinkle three to four tablespoons of baking soda over the surface, slowly pour a full kettle of boiling water over it, and let it soak for ten to fifteen minutes. The alkaline heat breaks down polymerized fat at the molecular level. Scrub with a nylon brush, rinse, and repeat as needed. For truly carbonized buildup (black, hard residue that does not lift with baking soda), apply Zep Heavy-Duty Degreaser (Home Depot, approximately $15 per litre), leave five to ten minutes, scrub with a nylon brush, and rinse thoroughly. If the filter metal is bent, corroded, or structurally compromised after cleaning, replace it — a damaged filter is a fire hazard. Replacement mesh filters cost $20–45 at Canadian Tire, Home Depot, or from the hood manufacturer.
Q: Who is responsible for range hood maintenance — tenant or landlord in Quebec?
A: Under Article 1854 of the Quebec Civil Code, the landlord must maintain the dwelling and its appliances in habitable, working condition. In practice: filter cleaning, bulb replacement, and light wiping of the hood surfaces are the tenant's responsibility as part of routine dwelling maintenance. If the fan motor fails, the damper breaks, or the hood unit needs replacing due to normal wear, that is the landlord's responsibility. Document any malfunction in a written notice to the landlord (email is acceptable) and keep a copy for your records. For condos, the DCC syndicate's responsibility is limited to the shared exhaust shaft infrastructure; the range hood unit inside your unit is your responsibility as owner or per the terms of your lease.
Q: My stainless steel range hood has white calcium spots that won't come off with dish soap. What should I do?
A: Those are calcium carbonate deposits from Montreal's hard water (90–150 mg/L). Dish soap removes grease but not mineral scale. You need a mild acid: dampen a microfibre cloth with undiluted white vinegar (IGA, Maxi, or Dollarama, approximately $3–5 per 4 L) and press it firmly against the spots for three to five minutes. The acetic acid dissolves calcium carbonate. Wipe with a clean damp cloth, then buff the surface completely dry with a fresh microfibre cloth following the steel grain direction (parallel strokes, never circular). Finish by applying a very thin film of mineral oil (Jean Coutu, approximately $6) with a dry cloth — this conditions the steel surface and creates a light protective barrier against future water spots and fingerprints.
Q: My pre-war Montreal apartment has no range hood and my landlord refuses to install one. What are my rights?
A: The absence of a range hood is not automatically a violation of Quebec's residential housing standards, but it depends on whether ventilation is adequate overall. If cooking fumes are causing excessive humidity, mold growth, or structural damage to the unit's ceilings and walls, this creates an argument that the dwelling is not in habitable condition under Article 1910 of the Civil Code. Your first step is to raise the issue formally in writing to the landlord. If the landlord refuses and conditions are genuinely problematic, you can file a request with the Tribunal administratif du logement (TAL) asking that ventilation improvements be ordered, or requesting a proportional rent reduction. In practice, many pre-war triplex kitchens operate legally without range hoods — using a splatter screen, keeping windows open, and running a portable air purifier are the practical interim measures most TAL inspectors would expect to see in place before entertaining a formal complaint.
