The kitchen is the hardest room to deep clean in any Montreal home. It is also the room where regular weekly cleaning falls furthest behind. Every time you cook, micro-droplets of fat and water vapour coat the nearest surfaces. Over weeks those droplets polymerize — they cross-link into a sticky film that ordinary dish soap on a sponge cannot dissolve. By the time you notice the build-up, you are dealing with a chemical compound that is genuinely difficult to remove without the right approach.
This guide covers every surface in the kitchen in the right order, with the right chemistry for each material. It also addresses the specific challenges of Montreal kitchens: older triplex units without range hoods, condos with DCC ventilation restrictions, and heritage wood cabinetry that is damaged by the wrong cleaning product.

Before You Start: Gather Your Supplies
A thorough kitchen deep clean takes 3–5 hours for an average Montreal apartment. Interrupted cleaning — stopping halfway because you ran out of a product — leaves surfaces in worse shape than when you started. Gather everything before you begin:
- Enzyme-based degreaser for baked-on and polymerized grease (sold at IGA, PA, or Jean Coutu)
- General-purpose spray degreaser for cabinet doors and range hoods
- Baking soda and white vinegar for the sink, drain, and odour control
- Microfibre cloths — 6–8 clean ones; paper towels leave lint on glass and dark surfaces
- Stiff dish brush and an old toothbrush for grout, burner grates, and faucet bases
- pH-neutral wood cleaner (Murphy Oil Soap or equivalent) for wood cabinets — never use vinegar on wood
- Granite or stone spray if you have sealed stone counters; vinegar etches granite and marble permanently
- Vacuum for dust behind the refrigerator
- Flat mop for the floor, always last

Step 1: Cabinets — Inside Before Outside
Empty every cabinet and wipe the interior with a damp microfibre cloth wrung out tightly. Use warm water with a drop of dish soap on the shelves. Dry thoroughly before returning items — trapped moisture causes mould inside enclosed cabinets over Montreal's humid summers.
For exterior doors and handles, use the cleaner appropriate to your cabinet material:
- Painted MDF or thermofoil (common in 1980s–2000s condos): warm water plus mild dish soap only. Solvent-based degreasers lift the paint or the thermofoil wrap
- Real wood veneer or solid wood (common in older triplexes and Victorian-era homes): pH-neutral wood cleaner only. Vinegar, lemon juice, bleach, and most multi-surface sprays contain acids or alcohols that dry out the finish and grey the wood over time
- Stainless steel cabinet doors (higher-end condos): commercial stainless steel cleaner applied with the grain of the metal
For grease-heavy cabinet exteriors — particularly above the stove — spray an enzyme-based degreaser, wait 5 minutes for the enzymes to work, then wipe with a microfibre cloth. Do not scrub; the enzyme needs dwell time to break the polymer chains.

Step 2: Oven
Standard ovens: Apply a commercial oven cleaner or a thick baking soda and water paste. Leave it for 4–6 hours or overnight. Wipe clean with a damp cloth, then wipe again with a cloth dampened with diluted white vinegar to neutralize any alkaline residue.
Self-cleaning ovens: Self-cleaning cycles reach 480–540°C and produce smoke. In buildings with shared ventilation systems — particularly older Montreal triplexes and apartment towers — running the self-cleaning cycle without open windows can trigger building fire alarms. Check with building management before using this function. Manual cleaning is safer and more predictable.
Gas range pilot lights: If your oven has a continuously burning pilot light — older gas ranges from the 1970s–1980s, still common in some NDG and Plateau triplexes — extinguish it before applying any liquid cleaner. Relight only after all surfaces are completely dry.

Step 3: Refrigerator
Remove all food and all removable shelves and drawers. Wash shelves and drawers in the sink with warm soapy water — but not very hot water; the thermal shock can crack glass shelves. Let them return to room temperature before reinserting.
Wipe the interior walls with a solution of 1 tablespoon of baking soda per 1 litre of water. This cleans without leaving a chemical taste or smell in the refrigerator.
The coils: Pull the refrigerator forward and vacuum the condenser coils at the back or underneath. Dust-caked coils force the motor to work harder. In older Montreal apartments where refrigerators sit close to the wall, coil cleaning is commonly skipped for years. A clean coil set reduces electricity use by 10–15% and extends the appliance life.
Clean the door gasket (the rubber seal) with a toothbrush and diluted dish soap. Mould in dirty gaskets is invisible in the folds and actively cross-contaminates food.
---
Step 4: Stovetop and Range Hood
Electric coil burners: Remove the coil burners (they unplug) and the drip pans. Soak drip pans in hot soapy water for 30 minutes. Wipe the coil elements themselves with a damp cloth only — they cannot be submerged.
Glass-ceramic flat-top ranges (common in post-2000 condos): Use a ceramic cooktop scraper at a shallow 30-degree angle for baked-on residue. Abrasive scrubbies permanently scratch the glass surface.
Gas burner grates: Soak in hot soapy water for 20 minutes. For heavy carbonized residue, a paste of baking soda and dish soap left for an hour loosens debris without requiring metal scrapers.
Range hood grease filters: Soak aluminium filters in hot water with a squeeze of dish soap and a quarter cup of baking soda for 20 minutes — the grease dissolves out. Rinse and air-dry before reinstalling.
Triplex kitchens without range hoods: This is the defining challenge of Montreal triplex kitchen cleaning. Without mechanical extraction, cooking fat accumulates directly on every nearby surface — cabinets, ceiling, walls, and the light fixture above the stove. These surfaces require the enzyme-based degreaser protocol (spray, dwell 5 minutes, wipe) rather than standard multi-surface spray. Enzyme degreasers break down polymerized fat at a molecular level; other cleaners simply move it around.

Step 5: Sink, Faucet, and Backsplash
Stainless steel sink: Wet the sink, coat with baking soda, and scrub with a soft sponge. For hard water mineral deposits around the drain, lay a vinegar-soaked cloth over the deposit for 30 minutes, then scrub.
Faucet base and aerator: Scrub the deposit ring around the base with a toothbrush and diluted dish soap. Unscrew the aerator at the tip of the faucet and soak it in a small container of white vinegar overnight to dissolve mineral scale.
Ceramic tile backsplash: Spray with a general-purpose cleaner and wipe. For grout lines, use a stiff toothbrush with baking soda paste or a commercial grout cleaner. Montreal's moderately hard water (90–150 mg/L calcium carbonate) deposits white calcium scale in grout, especially near the sink.
Natural stone backsplash (granite, marble, travertine — increasingly common in Plateau, Outremont, Westmount, and Côte-des-Neiges renovations from the 2000s onward): never use vinegar, lemon juice, or bleach on natural stone. Acids etch the polished finish permanently. Use a pH-neutral stone cleaner only.

Step 6: Countertops
| Countertop type | Right cleaner | What to avoid | |---|---|---| | Laminate (most common in older units) | Mild dish soap + water | Bleach (whitens seams), abrasives (scratch surface) | | Granite / quartz | pH-neutral stone spray | Vinegar, lemon, bleach (etches sealant or resin binders) | | Butcher block / wood | Food-safe mineral oil after cleaning | Soaking with water (warps wood) | | Stainless steel | Stainless spray, applied with the grain | Bleach (pits the metal), steel wool (scratches) |
---
Step 7: Floor
Sweep or vacuum first — always before mopping. Mopping an unswept floor moves crumbs into the mop water and smears them across the surface.
Ceramic tile with grout (common in pre-1980s triplexes and bungalows): a diluted white vinegar solution (1 part vinegar, 4 parts water) removes mineral deposits from grout lines on ceramic tile. Do not use vinegar on natural stone tile.
Vinyl or LVP flooring (common in post-2010 renovations): damp mop with a pH-neutral floor cleaner. LVP can be damaged by standing water — wring the mop thoroughly.
Hardwood or engineered hardwood: a barely-damp microfibre flat mop with a hardwood-specific cleaner (Bona or equivalent). Never soak a wood floor. Many Montreal old-stock hardwood floors are oil-finished rather than polyurethane-coated — these require oil-finish-specific cleaners and should never be steam-mopped.

DIY vs. Professional Deep Clean: When to Call a Pro
Most monthly kitchen maintenance is manageable as DIY work. A full deep clean — oven interior, refrigerator coils, inside all cabinets, range hood filter, and tile grout — takes 3–5 hours of focused effort. A professional team has commercial-grade enzyme degreasers, correct PPE for oven chemicals, and practiced technique that cuts the time roughly in half.
Situations where professional is worth it: - Move-out: Quebec [TAL inspections](/en/blog/how-to-choose-move-out-cleaner-montreal) evaluate kitchens closely for grease and mineral deposits; a professional team knows exactly what inspectors check for - Post-renovation: drywall compound dust reaches inside kitchen cabinets and requires HEPA vacuum plus wipe protocol before storing food - Move-in to a new rental: the previous tenant's build-up is your problem — see our [move-in cleaning checklist](/en/blog/move-in-cleaning-checklist-montreal) for what to inspect before you unpack - Heavy cooking households: kitchens that produce high-oil cuisine (South Asian, Caribbean, West African, Mediterranean) build polymerized grease faster than a single DIY session can fully address
2026 professional kitchen cleaning costs in Montreal:

Frequently Asked Questions
Q: How long does it take to deep clean a kitchen in Montreal?
A: For an average 2–3 bedroom apartment or condo kitchen, plan 3–5 hours to do it properly: oven (1 hour), refrigerator (45 minutes), all cabinets inside and out (1 hour), countertops, sink, and backsplash (45 minutes), and floor (30 minutes). A professional cleaning team of two people completes the same deep clean in 1.5–2.5 hours.
Q: What is the difference between a regular clean and a deep clean of a kitchen?
A: Regular cleaning maintains visible surfaces: wiping counters, washing dishes, sweeping. Deep cleaning removes accumulated build-up that regular cleaning misses — baked-on oven residue, polymerized grease on cabinet fronts, mould in refrigerator door gaskets, mineral scale in tile grout, and dust on condenser coils. Deep cleaning reaches inside cabinets, behind and under appliances, and into the oven interior. Most households benefit from a full kitchen deep clean two to four times per year.
Q: How do I clean a kitchen in a Montreal triplex without a range hood?
A: Without a range hood, cooking vapours deposit fat on all surfaces within one to two metres of the stove — including the ceiling, upper cabinets, and light fixtures — and that fat polymerizes into a hard film. Standard multi-surface sprays do not dissolve it. Use an enzyme-based degreaser: spray the surface, wait five minutes for the enzymes to break down the polymer chains, then wipe with a microfibre cloth. Prevent future build-up by covering pots when frying and opening a window during cooking.
Q: Can I deep clean my kitchen without strong chemicals?
A: Yes. Baking soda and dish soap paste handles most oven residue and stainless steel. White vinegar dissolves mineral scale on ceramic tile and stainless sinks. Enzyme-based degreasers sold as natural formulas at IGA or Jean Coutu are highly effective on grease without the fumes of chemical degreasers. The main exception is a heavily soiled oven, where a commercial alkaline cleaner is more effective than baking soda. Use it with windows open.
Q: How often should I deep clean my kitchen in Montreal?
A: Cooking 3–5 times per week, a full kitchen deep clean every three months is practical. The oven interior and range hood filter need it most. In summer, open windows let cottonwood pollen and airborne dust settle on greasy surfaces faster than usual — a wipe-down of cabinet fronts after pollen season in May–June prevents it from bonding into a harder layer.
Q: When should I hire a professional to deep clean my kitchen instead of doing it myself?
A: The main cases: move-out (TAL inspections hold you to a high standard); post-renovation (drywall dust requires HEPA vacuuming inside cabinets before storing food); multi-year grease build-up (requires multiple enzyme-degreaser sessions and significant time); and high-frequency, high-fat cooking households. Our [deep cleaning service](/en/services/deep-cleaning) covers all of these — book a [move-in/out cleaning](/en/services/move-in-out-cleaning) for end-of-lease situations.
