Every Montreal kitchen has at least one of these four cookware families: cast iron, non-stick (PTFE or ceramic), stainless steel, and enameled cast iron (Le Creuset, Staub, Lodge). Each material demands a completely different cleaning and maintenance protocol — and getting it wrong is surprisingly destructive.
Scrub a Le Creuset interior with steel wool: the enamel is permanently scratched. Run your Teflon pan through the dishwasher for three months: the PTFE layer will start flaking. Leave a bare cast iron skillet in a damp Montréal basement buanderie from November to April: you'll come back to solid rust. This guide covers all four families, with specific attention to Montreal conditions: hard water (90–150 mg/L CaCO₃), six-month winter storage, and the Quebec cooking cultures that are hardest on specific surfaces.

Cast Iron and Carbon Steel
The "No Soap" Myth
You can use a small amount of mild dish soap (Dawn, Sunlight) on cast iron. Modern dish soaps contain no lye — the only substance that actually stripped seasoning in old cast iron cookbooks. What does damage seasoning: soaking in water, dishwasher cycles, prolonged acid cooking (tomato sauce, wine reductions) in an unseasoned pan, and scrubbing with steel wool.
Daily Cast Iron Care
1. Rinse while still warm — never pour cold water on a very hot pan (thermal shock) 2. Scrub with a chainmail scrubber or coarse salt for stuck food 3. Place on the burner over medium heat for 2–3 minutes until bone-dry 4. Apply a paper-towel-thin coat of neutral oil while still warm, wiping until barely visible 5. Store in a dry location — crucial in Montreal, where basement buanderies reach 65–75 % RH during the heating season
Rust Removal — Montreal Buanderie Season
Montreal's basement buanderies are notoriously humid, particularly between November and April when cold basement air stays heavy with moisture. If you find orange rust after winter storage:
1. Scrub rust with steel wool or a coarse wire brush (you need the abrasion here — not your chainmail) 2. Wash with soap and water 3. Dry completely on the stovetop burner 4. Re-season in the oven: apply a very thin coat of flaxseed oil or canola with a paper towel until barely visible; place the pan upside down in a 230 °C (450 °F) oven on foil for one hour; let cool in the oven; repeat 3–5 cycles for a solid black patina
Montreal-Specific Cast Iron Notes
- Maple syrup glazed recipes (poulet à l'érable, salmon au sirop, crêpes): the sugar caramelizes and bonds instantly — deglaze while still hot with a tablespoon of water and a wooden spoon before washing
- Italian-Canadian ragù and long tomato braises (very common in Saint-Léonard, LaSalle, RDP kitchens): acidic tomato sauce slowly erodes unseasoned cast iron; use a well-seasoned pan with at least 5 seasoning layers, or switch to enameled cast iron for braises over 45 minutes
- Tourtière and tarte au sucre in Québécois households: cast iron gives the crispy bottom crust both recipes need; season the pan well before the pastry season (October–December)

Non-Stick Cookware (PTFE and Ceramic)
What Destroys Non-Stick Coatings
- Steel wool or abrasive sponges — even one use can score the PTFE layer permanently
- Dishwasher — the high-heat dry cycle and alkaline detergent degrade coating; with regular dishwasher use, a Teflon pan's coating starts micro-cracking within 3–6 months
- Metal utensils — metal spatulas create fine scratches that widen with use
- Preheating empty on high heat — overheating PTFE above 260 °C releases decomposition compounds harmful to pet birds; above 300 °C can affect humans
- Stacking without pan protectors — dragging surfaces across each other scores the coating
Proper Non-Stick Cleaning
1. Let the pan cool before washing — thermal shock can separate the PTFE coating from the aluminum base 2. Handwash with warm water and mild dish soap using a soft sponge 3. For baked-on residue: fill with warm water and a drop of dish soap, soak 15 minutes, then wipe gently — never scrub hard 4. Dry immediately with a soft cloth 5. Store with a paper towel or pan protector between stacked pans
When to Replace
If you can see the grey aluminum base through scratches, or if the coating is visibly flaking, replace the pan. Quebec environmental awareness tends toward caution on PFAS/Teflon; reputable brands at Canadian Tire, Home Depot, and Stokes sell well under $50 and last 3–5 years with proper handwashing.

Stainless Steel Pots and Pans
Montreal Hard Water Scale Inside Pots
Montreal tap water (90–150 mg/L CaCO₃) leaves a white, cloudy film inside stainless steel pots after boiling water for pasta or blanching vegetables. This calcium carbonate scale is harmless but unappealing.
To remove calcium scale from stainless pots: 1. Fill with water and add ½ cup white vinegar 2. Bring to a boil, then let cool 15 minutes 3. Pour out and scrub with a non-scratch sponge 4. Rinse well with cold water
Rainbow Discolouration
The blue/purple/gold discolouration inside stainless pans comes from extreme heat — very common on Montreal gas stoves running high for weeknight searing. This is chromium oxide; it is harmless and fully removable.
Apply Bar Keepers Friend cream or powder with a damp non-scratch sponge, rubbing with the grain of the metal surface (not circular motions). Rinse thoroughly. Available at Canadian Tire for approximately $6–9.
Stuck-On Burnt Food
Deglaze while still warm: add a small amount of water to the hot pan and the stuck food loosens immediately. For cold stuck-on residue: fill with water and dish soap, bring to a low boil for 5 minutes, then scrub with a non-scratch sponge and Bar Keepers Friend if needed.

Enameled Cast Iron (Le Creuset, Staub)
Le Creuset and Staub are deeply embedded in Quebec cooking culture. The France-inspired Québécois culinary tradition means enameled Dutch ovens appear in kitchens across Outremont, Westmount, TMR, Plateau, and NDG at unusually high rates. Costco (Kirkland, Laval, Brossard) rotates Le Creuset and Staub stock that sells out quickly; Zone Maison and Zone Culinaire in Plateau and Old Port carry full lines.
What Damages Enamel
- Thermal shock — placing a very hot Dutch oven on a cold surface, or adding cold liquid to a hot dry pot, can crack or craze the enamel
- High-heat empty preheating — enamel over bare flame above 260 °C without liquid can develop a network of micro-cracks
- Metal utensils on the interior — use only wooden, silicone, or nylon utensils
- Steel wool or abrasive powders (Comet) on the coloured exterior enamel — removes the vitreous layer permanently
- Repeated dishwasher cycling — allowed by some manufacturers, but dulls the exterior gloss finish over time
Daily Le Creuset / Staub Care
1. Let cool completely before washing — this is the single most important step 2. Fill with warm water and a drop of dish soap — soak 10–15 minutes for stuck food 3. Wash interior with a soft sponge — the nylon brush sold with the pot is ideal 4. Stubborn interior staining (tomato, red wine, turmeric from Moroccan/West African/South Asian braises): dissolve 1–2 teaspoons of baking soda in enough water to cover the stains and soak 8–12 hours; this lifts organic staining from the cream interior enamel without any abrasion 5. Exterior bottom blackening: Bar Keepers Friend CREAM (not powder) applied gently with a soft cloth; rub lightly, rinse thoroughly
TAL Move-Out Note
Given Le Creuset's price ($200–$400 per piece), TAL unit inventories in Montreal rental units occasionally list Le Creuset cookware as landlord-provided. Tenants who have chipped or cracked the enamel through thermal shock may face deductions. Normal interior staining from cooking (tomato, wine, spices) is not considered damage in TAL jurisprudence; physical chips and large cracks are.

Frequently Asked Questions
Q: Can I use dish soap on cast iron?
A: Yes. Modern dish soaps (Dawn, Sunlight, Ivory) contain no lye, so a small amount will not strip your pan's seasoning. The rule about "never use soap" comes from 20th-century cast iron cookbooks written when lye-based soaps were common. The keys are: wash quickly, dry immediately on a burner over heat, and apply a thin oil coat while still warm. What genuinely damages cast iron is soaking in water, running it through the dishwasher, and prolonged cooking of highly acidic foods (tomato sauce, wine) in an unseasoned pan.
Q: Why does my non-stick pan stick after a few months of dishwasher use?
A: The dishwasher's high-heat drying cycle and alkaline detergent degrade PTFE coatings faster than any other cleaning method. After repeated cycles, micro-cracks form in the coating surface that grip food. Once a non-stick pan begins sticking, the coating is compromised — replacing the pan is the right move. Handwashing in warm water with a soft sponge extends non-stick life to 3–5 years; dishwasher use shortens it to 6–18 months.
Q: How do I remove the rainbow or heat tint from the inside of my stainless steel pan?
A: The rainbow/blue/gold tint is chromium oxide from overheating — it is completely harmless and fully reversible. Apply Bar Keepers Friend cream or powder to a damp non-scratch sponge and rub with the grain of the metal surface (parallel to any faint brush lines), not in circular motions. Rinse thoroughly. Bar Keepers Friend contains oxalic acid, which dissolves chromium oxide without damaging the stainless steel. Available at Canadian Tire for $6–9.
Q: My Le Creuset interior is dark from years of tomato sauce and red wine. How do I clean it without damaging the enamel?
A: Fill the Dutch oven with 1–2 teaspoons of baking soda dissolved in water, enough to cover the stained area, and let it soak for 8–12 hours or overnight. The baking soda dissolves and lifts organic staining from the cream enamel without any abrasion. For stubborn staining, a 10-minute low simmer of the baking soda water often completes the job. Never use steel wool, abrasive powder cleaners like Comet, or Bar Keepers Friend powder on the interior enamel — these permanently scratch and weaken the glass coating.
Q: I left my cast iron in the basement buanderie all winter and it's covered in rust. Can I save it?
A: Yes — rust does not permanently ruin cast iron. Scrub the rust vigorously with steel wool or a coarse wire brush (not your usual chainmail — you need maximum abrasion). Wash with soap and water. Dry completely on the stovetop over heat. Then re-season in the oven: apply a barely-visible coat of flaxseed oil or canola with a paper towel, place the pan upside down in a 230 °C (450 °F) oven on foil for one hour, and let cool in the oven. Repeat 3–5 times to build a new base layer of seasoning. To prevent recurrence, apply an oil coat before winter storage and keep cast iron in a heated room, not a cold humid basement.
Q: Is a scratched non-stick pan dangerous to use?
A: Minor surface marks from 1–2 years of normal cooking use are not considered dangerous — PTFE is chemically inert and the microscopic particles from light surface wear are not absorbed by the body. The point to stop using a non-stick pan is when you can see the bare aluminum base beneath the coating, or when the coating is visibly peeling in flakes. At that stage, replace the pan. If you cook with pet birds in the home, replace Teflon pans more conservatively: overheated PTFE releases fumes that are toxic to birds at temperatures well below the threshold that affects humans.
