Nowhere in North America is a good down jacket more essential than Montreal. Winters swing from a wet 0°C November to a brutal −25°C January cold snap, with wind chills routinely below −35°C for weeks on end. From Canada Goose parkas that walk the Plateau to Kanuk coats stitched in a Rachel Street workshop to the North Face and Arc'teryx jackets everywhere on Mount Royal, down insulation is what stands between a Montrealer and frostbite.
But every February, laundromats across the island fill with sad, wet, clumpy down jackets that owners have accidentally destroyed by throwing them in the wrong wash cycle. A $1,000 Canada Goose Expedition Parka can be permanently ruined in a single incorrect drying cycle. A Kanuk warranty can be voided by using the wrong detergent. And the "wet dog" smell that lingers for days after a bad wash is entirely preventable if you understand what down actually needs.
This guide walks through everything: pre-wash inspection, choosing a wash method (hand wash, front-loader, laundromat), the tennis-ball drying protocol that restores loft, DWR (water-repellent coating) restoration, dealing with hard-water clumping, and Montreal-specific seasonal storage between April and November.

Why Down Cleaning Is Completely Different from Regular Laundry
Down is not fabric. It is thousands of tiny bird plumules — three-dimensional clusters of interlocking filaments — that trap air. That trapped air is what insulates you. When you understand this, every rule about washing down starts to make sense.
- Regular detergent strips the natural oils that keep down filaments flexible. Stripped filaments become brittle, break, and lose their loft permanently.
- Fabric softener coats the filaments with a waxy residue that ruins their ability to trap air. Never use fabric softener on down.
- Agitator washing machines twist and tear the down clusters, causing permanent loft loss. Top-loaders with a central agitator are the single biggest destroyer of down jackets in Canada.
- Hot water melts the DWR coating on the shell fabric and dissolves the natural oils in the down itself.
- Insufficient drying leaves damp clumps at the core of each baffle. Damp down grows bacteria within 24 hours — this is the source of the infamous "wet dog" smell — and can develop mildew that permanently damages the jacket.
Every single down-care instruction in this guide traces back to one of those five principles.

Before You Wash: Read the Label, Then Inspect the Jacket
Every reputable down jacket has a care label sewn into an inside seam. It will specify one of three things:
1. Machine washable, cold, gentle cycle (most modern down jackets, including The North Face, Patagonia, Arc'teryx, Canada Goose newer models, Uniqlo, Columbia) 2. Hand wash only (Kanuk explicitly recommends hand-washing to preserve their lifetime warranty; some vintage down jackets; jackets with real fur trim not certified washable) 3. Dry clean only (leather trim, some technical shell fabrics, embellished or heavily branded pieces)
If the label says "dry clean only," take the jacket to a specialist — not a strip-mall dry cleaner. A regular dry cleaner uses perchloroethylene solvent that strips down of its natural oils and destroys loft. In Montreal, look for a dry cleaner that explicitly advertises "down cleaning" or "outdoor gear cleaning" as a specialty. Nettoyeur écologique locations that use wet-cleaning solvents (silicone-based or hydrocarbon) are safer for down than traditional perc cleaners.
Pre-wash inspection checklist:
- Check every pocket. Tissues, gum wrappers, coins, receipts, and forgotten OPUS cards all cause problems in the wash. A pen leaking in a Canada Goose pocket is a $1,500 lesson.
- Zip everything closed — main zipper, hand-warmer pockets, chest pockets, wrist tabs. Open zippers snag other garments and stretch out.
- Loosen or remove drawcords so they don't tangle around the agitator or drum.
- Turn the jacket inside out to protect the shell and expose the lining, which is often where the most sweat and body-oil residue lives.
- Detach removable fur ruffs and hoods. Real coyote fur (Canada Goose, Nobis, Mackage) must never be washed. Faux-fur trim usually has a wash instruction on the trim itself.
- Spot-treat visible stains before the full wash. See the stain section below.

Choose Your Wash Method
Method 1: Front-loading machine wash (easiest, works for 90% of down jackets)
You need: a front-loading washing machine (NEVER a top-loader with a central agitator), a down-specific detergent, and about 2 hours.
- The right detergent. Regular liquid detergent (Tide, Persil, etc.) is too aggressive and strips natural oils. Use a technical-fabric down wash: Nikwax Down Wash Direct (widely stocked at MEC on Peel Street and Décathlon in Brossard), Grangers Down Wash, or Storm Care Down Wash. Each roughly $10–$18 for a bottle that washes 5–10 jackets. Cheap alternative: unscented free-and-clear detergent (Ecos Free and Clear, Nature Clean) in half the usual dose.
- Machine settings. Cold water. Gentle or delicate cycle. Extra rinse turned ON — this is critical because Montreal's moderately hard water (90–150 mg/L CaCO₃) interacts with residual detergent to create the classic clumpy-down problem.
- Load the machine. Just the jacket. Never add towels or other garments — friction damages the shell fabric and can tear internal baffles.
- Run the cycle. When it finishes, run the rinse cycle a second time. Yes, again. Any residual detergent will cause clumping and irreversible loft loss.
- Do not wring, twist, or pick up by the collar. A wet down jacket weighs 3–5× more than dry. Lift it into the dryer with both hands supporting it like a large baby.
No front-loader at home? In Montreal, front-loading commercial machines are standard at most laundromats (Blanchisserie Le Plateau, Buanderie Net Cité, and the newer Cleanpanther-adjacent laundromats in NDG and Verdun). Bring your own down detergent — laundromats don't stock it. Cost per wash: $4–$8 including the dryer time (which will be 90 minutes minimum — see below).
Method 2: Hand wash (mandatory for Kanuk warranty jackets and any hand-wash-only label)
You need: a clean bathtub, down-wash detergent, and about 3 hours.
- Fill your bathtub with 10 cm of lukewarm water (never hot — hot water melts DWR).
- Add 1–2 tablespoons of down wash (Nikwax or equivalent). Stir to dissolve.
- Submerge the jacket. Press it down repeatedly with clean hands — do not scrub, twist, or wring. Let it soak 15–20 minutes.
- Drain the tub completely. Press excess soapy water out of the jacket by walking on it barefoot (with clean feet, on a clean tub surface) or pressing gently with your palms.
- Rinse. Fill the tub with fresh cold water. Press the jacket down repeatedly to flush detergent. Drain. Repeat this rinse three or four times until the water runs completely clear. Any residual detergent will cause clumping.
- Do not lift by the collar — the wet weight can tear the collar seam. Roll the jacket up in the tub, then carry it in your arms into the dryer.
Method 3: Do NOT use a top-loader with a central agitator
This is the single biggest cause of ruined down jackets in North American laundry rooms. The plastic post in the middle of the drum twists and tears down clusters, permanently reducing loft. If your building's laundry room only has top-loaders, take your jacket to a laundromat with a front-loader instead. It is genuinely worth the $6 trip.

The Drying Stage Is Where Down Is Won or Lost
Drying takes far longer than washing and is where most people ruin the jacket. Down that isn't fully dry within 4–6 hours starts growing bacteria at the core of every baffle. This is the "wet dog" smell.
Setup:
- Dryer setting: LOW HEAT or NO HEAT. Never medium, never high. Down's natural oils melt at temperatures above 60°C. High heat also melts the DWR coating and can scorch synthetic shell fabrics.
- Add three or four clean tennis balls to the dryer. As the drum tumbles, the tennis balls repeatedly strike the wet clumps of down, breaking them apart and restoring loft. Dedicated dryer balls (wool or plastic) work equally well; new tennis balls are the cheapest option ($3–$5 at Canadian Tire).
- Dry time: 2 to 4 hours minimum. A large parka (Canada Goose Snow Mantra, Kanuk Fitz Roy) can need 3–5 hours. A lighter puffer (Uniqlo Ultra Light Down) may only need 60–90 minutes.
- Every 30 minutes, pause the dryer. Take the jacket out. Squeeze each baffle with your hands. Feel for cold, damp clumps — these are compressed wet down. Break them up by pinching and rolling between your fingers. Return the jacket to the dryer.
- Final test. The jacket is dry only when every single baffle has bounced back to full loft and there is not one cold spot when you press the jacket to your cheek. If in doubt, run it another 30 minutes.
Do NOT air-dry a wet down jacket in a Montreal apartment during winter. Indoor RH is already 20–40% in a Quebec winter apartment, evaporation is slow, and by the time the outer shell feels dry (24–48 hours) the interior baffles have already started growing bacteria. The tumble dryer is not optional for down.
If you have no dryer — some Plateau walk-ups still don't — take the jacket to the laundromat for the dry cycle even if you hand-washed it at home. Bring five loonies. Do NOT hang a wet down jacket over a heater or radiator; the intense localized heat scorches the down and warps the baffles.

Restoring the DWR (Water-Repellent Coating)
Every technical down jacket ships with a factory DWR (durable water repellent) coating on the shell fabric. It is what makes water bead and roll off instead of soaking in. DWR gradually wears off with use, and every wash cycle strips more of it.
Signs your DWR needs restoration:
- Rain or wet snow soaks into the shell fabric instead of beading up.
- The shell fabric feels "wet" and heavy in light snow.
- The down beneath the shell gets damp during normal winter wear.
How to restore it:
1. Wash the jacket first (DWR treatment only adheres to a clean surface). 2. Apply a wash-in DWR treatment while the jacket is still slightly damp: Nikwax TX.Direct Wash-In ($16–$22 at MEC, Décathlon, Latulippe, and some Canadian Tire locations) or Grangers Performance Repel Plus. Follow the bottle directions — typically one full cycle in the washing machine with the treatment added instead of detergent. 3. Heat activates DWR. After the wash-in treatment, tumble dry on low with tennis balls for the full drying cycle. The gentle heat locks the DWR onto the shell fibres.
Alternative: spray-on DWR (Nikwax TX.Direct Spray-On) applied to the exterior of a dry jacket. Slightly less durable than wash-in but useful for touch-ups between full washes. Apply outdoors or in a well-ventilated garage — never inside a Montreal apartment.
DWR restoration is typically needed every 20–40 wash cycles or every second year of heavy use, whichever comes first.

Dealing With the "Wet Dog" Smell
If your down jacket already smells musty or "wet dog" after a wash, one of two things happened:
1. It wasn't fully dry at the end of the drying cycle, and bacteria grew inside the baffles. 2. Detergent residue was left behind and reacted with body oils and moisture over time.
The fix (works for both):
- Rewash the jacket with no detergent at all on a cold gentle cycle with the extra-rinse option turned on.
- Add half a cup of white vinegar to the fabric-softener compartment (or a Downy Ball). The mild acetic acid neutralizes bacterial odour and helps flush residual alkaline detergent.
- Dry it fully — 3+ hours with tennis balls on low heat, pausing every 30 minutes to break up clumps and check for cold spots.
- If odour persists after one rewash: repeat, this time with Nikwax Tech Wash (a rinse-free technical fabric cleaner) instead of vinegar.
Do not use bleach, Febreze, or fabric softener on down. Bleach dissolves the down. Febreze masks odour without addressing bacterial cause. Fabric softener coats the filaments with wax and permanently kills loft.

Spot-Cleaning Between Full Washes
A full wash is stressful on a down jacket. Ideally, you wash it once or twice a season. Between washes, spot-clean visible stains:
- Collar and cuff grime (body oil + street grime): Damp cloth with a drop of Nikwax Tech Wash or unscented mild soap. Blot, don't scrub. Rinse with a clean damp cloth. Air-dry in front of a fan (not a heater).
- Salt stains (from Montreal winter sidewalks): Wipe with a damp cloth. Dried salt residue can be brushed off with a soft brush. Persistent salt: dab with a 50/50 water-and-white-vinegar solution, then rinse with a clean damp cloth.
- Food and drink spills (coffee, mustard, wine): Blot immediately with a clean cloth. Do not rub — rubbing pushes stain deeper into the shell fabric and can reach the down beneath. Treat with a small amount of Dawn dish soap on a damp cloth, work in circles from outside stain edge toward centre, rinse with a clean cloth.
- Grease and oil stains (poutine, greasy takeout — this happens in Montreal): Dust with cornstarch or baby powder. Let it absorb the grease for 30 minutes. Brush off. Then treat with a drop of dish soap as above.
- Blood (nosebleed, cuts): Cold water only — hot water sets protein stains permanently. Dab with cold water and a small amount of hydrogen peroxide (3%) for stubborn spots. Rinse thoroughly.

Storing a Down Jacket for Montreal's Non-Winter Months
Montreal winter runs late October to early April. That means your down jacket is in storage for roughly six months a year. Improper storage causes more loft loss than actual winter wear.
Do:
- Store loose in a breathable cotton garment bag or hung on a wide, padded hanger in a cool, dry closet. Air circulation prevents mildew.
- Wash the jacket at end of season before storage — body oils, sweat, road salt, and food residue accelerate fabric degradation and attract insects.
- Store on a hanger with the jacket zipped closed — this preserves the front baffle shape.
- Use cedar blocks or lavender sachets as natural moth repellent. Cedar is available at Rona, Home Depot, and Renaud-Bray.
- Store in a room with 40–60% relative humidity. Basement storage in a Montreal duplex is fine if the basement is dry; check for musty smells before storing.
Don't:
- Never compress into a stuff-sack for long-term storage. Compression permanently damages loft. Stuff-sacks are for hiking transport only, not seasonal storage.
- Never store in a garment bag with mothballs (naphthalene). The odour is nearly impossible to remove from down and lingers for years.
- Never store in a hot attic. Summer attic temperatures reach 50°C in Montreal — this melts DWR and damages down.
- Never store in a plastic bag or vacuum bag long-term. Trapped moisture grows mildew that permanently damages the fabric and down.

Brand-Specific Notes
Canada Goose (any model): Modern Canada Goose jackets are machine-washable on cold gentle in a front-loader per the label. The brand explicitly disallows dry cleaning. Remove the coyote fur ruff before washing — real fur cannot be laundered. Canada Goose recommends professional laundering for the Snow Mantra (their heaviest expedition parka) due to size; most Montreal outdoor-gear specialists will service it.
Kanuk (Montreal-based, Rachel Street workshop, family-owned since 1970): Kanuk explicitly recommends hand-washing to preserve the lifetime warranty. Machine washing may void the warranty. Bring the jacket to the Kanuk Rachel Street atelier for professional laundering and inspection — they service their own jackets, including seasonal re-lofting for older coats.
The North Face, Patagonia, Arc'teryx, Columbia, Uniqlo: All manufacturer-approved for cold gentle machine wash in a front-loader with down-specific detergent. Uniqlo Ultra Light Down is the most forgiving — the smaller size and lighter fill make it easier to fully dry.
Nobis, Mackage, Moose Knuckles: Check the label carefully — many models have leather trim or real fur that requires professional cleaning. Machine washing risks warranty voidance.

When to Call a Professional
Down cleaning is a service some Montreal cleaners and laundromats offer. Consider professional cleaning when:
- The jacket is a $600+ investment and you've never washed one before.
- The label says dry-clean-only or the jacket has leather trim, real fur, or embellishments.
- Kanuk warranty jackets — the Rachel Street atelier is the definitive service point.
- The jacket is severely soiled (blood, oil, mud) beyond spot-cleaning.
- You've already had a bad-wash outcome (clumped down, wet-dog smell that won't leave) and want a professional recovery.
Expect to pay $40–$90 for down-specialist laundering of a full-length parka in Montreal. Traditional dry cleaners charging $20 to "dry clean" a down parka almost always use perc solvent that damages the down — always ask specifically about the cleaning method before dropping off an expensive jacket.
While your down jacket is in storage from May through September, this is the ideal moment to book seasonal deep cleaning for your closet, mudroom, and laundry room where winter gear lives. Our [home cleaning services](/en/services/home-cleaning) and [deep cleaning services](/en/services/deep-cleaning) can handle the entryway, closet interiors, and hallway floors that Montreal winter salt and slush trashed all season. If you're doing a full seasonal reset at the same time, our [move-in cleaning checklist](/en/blog/move-in-cleaning-checklist-montreal) works equally well as a seasonal home reset.

Frequently Asked Questions
Q: Can I wash a Canada Goose jacket in my apartment washing machine?
A: Yes, if it is a modern Canada Goose model with a "machine washable" care label and you have a front-loading machine (never a top-loader with a central agitator). Use cold water, gentle cycle, a down-specific detergent like Nikwax Down Wash Direct, turn extra rinse ON, and dry on low heat with three tennis balls for 2–4 hours. Remove the coyote fur ruff first — real fur must never go in a washing machine. The one exception is the Snow Mantra, which is oversized for most residential machines; take it to a Montreal outdoor-gear specialist.
Q: How do I fix a down jacket that came out of the dryer clumpy?
A: Clumping means either (a) the down is still damp inside the clumps, or (b) detergent residue is coating the filaments. Put the jacket back in the dryer on low heat with four tennis balls or dryer balls and dry for another 60–90 minutes, pausing every 20 minutes to manually break up the clumps by pinching and rolling each baffle. If the clumps persist after full drying, rewash the jacket on cold gentle with NO detergent and an extra rinse, then re-dry with tennis balls. Repeat until loft is restored. Severe long-standing clumping from repeated bad washes is sometimes unrecoverable.
Q: My down jacket smells like a wet dog after washing — what do I do?
A: The wet-dog smell is bacterial growth in down that never fully dried. Rewash the jacket cold gentle with NO detergent, add half a cup of white vinegar to the fabric softener compartment, run extra rinse, then dry with tennis balls on low heat for a full 3+ hours pausing every 30 minutes to break up clumps and feel for cold damp spots. The jacket is not dry until every baffle has full loft and there is no cool spot when pressed against your cheek. Persistent smell after two washes usually means the down has developed mildew and needs professional recovery.
Q: Is it worth paying for professional down jacket cleaning in Montreal?
A: For a Kanuk jacket, yes — the Rachel Street atelier services their own coats and preserves the lifetime warranty. For a $200 puffer, no — home washing in a front-loader works fine. For a Canada Goose, Nobis, or Mackage jacket with real fur trim, professional cleaning is worth the $50–$90 if you're uncertain, especially for the first wash. Avoid strip-mall dry cleaners that use perchloroethylene solvent — it strips down of its natural oils. Always ask specifically about cleaning method before dropping off an expensive jacket.
Q: How often should I wash my down jacket?
A: Once or twice per winter season for most Montrealers, plus one end-of-season wash before storage in April. Wash more often if the jacket is visibly stained, smells of body odour or smoke, or has been through a heavy sweat event (cross-country skiing on Mount Royal, hiking, an overheated Métro ride). Wash less often for lightly used jackets — every wash mildly degrades the down and the DWR coating, so unnecessary washing shortens jacket life. Between washes, spot-clean collar and cuff grime.
Q: Can I use a down jacket on a hanger to save space if my closet is small?
A: Yes — but use a wide, padded hanger to prevent shoulder-seam damage from the wet weight of a damp jacket, and store the jacket zipped closed to preserve the baffle shape. Never store a down jacket compressed in a stuff-sack for the off-season — long-term compression permanently damages loft. If closet space is tight in a Plateau or Mile-End walk-up, hang the jacket on a wall-mounted hook in the entryway during winter and move it to a breathable garment bag on the closet rod in April. Cedar blocks in the closet deter moths without leaving the persistent odour that mothballs do.
