A good down jacket is one of the best investments you can make for a London winter. It packs light, it traps heat brilliantly, and it copes with everything from a frosty walk across Clapham Common to a damp Northern line commute. But after a season of rain, sweat, city grime and the occasional coffee spill, even the best coat starts to look flat, smell stale and lose its warmth.
The good news is that you do not have to retire it. Learning how to wash a down jacket properly will restore its loft, freshen the fabric and extend its life by years. The bad news is that the wrong wash can leave you with a lumpy, damp, half-ruined coat. This guide walks you through everything: whether you can use your machine, how to dry the jacket, how to fix clumping, how to treat stains, how often to wash, and when it makes sense to hand the job to a specialist.
Why Down Jackets Need Proper Care
Down is the soft undercoat of ducks and geese. Each tiny cluster has thousands of fine filaments that trap air, and trapped air is what keeps you warm. When down is clean and dry, the clusters puff up (this is called loft). When they are coated in body oils, dirt or moisture, they collapse and stick together, and the jacket gets thinner and colder.
London is particularly demanding on outerwear. Traffic pollution leaves a fine film on fabric, Tube and bus journeys add sweat and odours, and our damp weather means jackets are often put away slightly moist. Over time this builds up inside the baffles (the stitched compartments that hold the filling) and the insulation starts to underperform.
Regular, correct washing does the opposite. It lifts out oils and dirt so the feathers can separate and expand again. Many people are surprised by how much warmer an old jacket feels after one proper clean.

Before You Start: Check the Label and Prepare the Jacket
A few minutes of preparation prevents most washing disasters.
Read the care label first
The care label is your starting point. It will tell you the maximum temperature, whether machine washing is allowed, and whether tumble drying is safe. Some designer or technical coats are marked “dry clean only”, and some have trims such as real fur, leather panels or special coatings that will not survive a wash. If the label says dry clean only, follow it, or ask a professional.
Empty the pockets and close everything
Check every pocket, including the hidden inner ones, for tissues, receipts and Oyster cards. Zip all zips, fasten Velcro tabs and snap buttons, and remove detachable hoods or fur trims. Open zips and loose Velcro can snag the fabric or damage the drum.
Repair small damage before washing
Look for tiny tears or loose seams. Water and agitation make holes bigger and can push feathers out through them. If you find a split, get it sorted first. Our clothing alterations and repairs team can mend seams, replace broken zips and patch small rips so the jacket goes into the wash in good shape.
Pre-treat any visible stains
Spot-treat marks around the cuffs, collar and pockets before the main wash (we cover this in detail further down). Pre-treating means you will not need to rub or scrub the jacket during washing.
How to Wash a Down Jacket in the Washing Machine
Can you machine wash a down jacket?
In most cases, yes. If the care label allows it, you can machine wash a down jacket safely, provided you use a front-loading machine, a gentle cycle, cool water and the right detergent. The one setup to avoid is a top-loader with a central agitator, which can twist, stretch and tear the baffles.
Two things matter more than anything else: the detergent and the drying. Ordinary laundry detergent and fabric softener leave residue that coats the down and stops it lofting. Always use a detergent made for down and technical outerwear.
What you will need
- A front-loading washing machine (large capacity if possible)
- A down-specific or technical wash liquid
- Two or three clean tennis balls or wool dryer balls
- A tumble dryer, or a warm room with plenty of airflow and a flat drying surface
If your machine is small (common in London flats), consider a launderette with a larger drum. A bulky coat needs room to move; if it is crammed in, the soap will not rinse out properly.
How to wash a down jacket step by step
- Wash one jacket at a time. Do not add other items. The coat needs space.
- Close all zips and fastenings, and turn the jacket inside out if the label suggests it, which protects the outer fabric.
- Add a small amount of down wash to the dispenser, following the bottle. Using too much is the most common mistake. Soap left in the filling is what causes dull, flat patches later.
- Choose a gentle or delicate cycle at 30°C or below, with a low spin speed.
- Add an extra rinse cycle. London has hard water, which can make detergent harder to rinse away, so this step is especially worthwhile in the capital.
- Take the jacket out carefully. It will look sad and sodden, but do not worry. Support the weight in your arms rather than pulling by the sleeves, as wet down is heavy and can stress the stitching.
Once the cycle finishes, press out excess water by gently squeezing. Never wring or twist the jacket.
How to Wash a Puffer Jacket by Hand
If your machine is too small or the label advises against machine washing, you can wash puffer jacket styles by hand in a bath or large basin.
- Fill the bath with lukewarm water, roughly 30°C.
- Add a small measure of down wash and swish it through.
- Lay the jacket in the water and press it down gently until fully submerged. Air will try to trap itself in the baffles, so keep pressing.
- Leave it to soak for 15 to 30 minutes, gently kneading dirty areas such as the collar and cuffs.
- Drain the bath and refill with clean lukewarm water. Rinse by pressing the jacket repeatedly until the water runs clear and no suds remain. This can take three or four rinses.
- Press the water out against the side of the bath. Do not wring.
Hand washing is slower, but it is the gentlest option, and it is a good choice for older jackets, lighter shell fabrics and anything you are nervous about. The drying steps below are exactly the same either way.
How to Dry a Down Jacket Properly
Drying is where most people go wrong, and it is the single most important stage. If a damp jacket is left to dry slowly, the down clumps, the inside can develop a musty smell and mildew can form. The aim is to dry a down jacket fully, evenly and fairly gently.
Tumble dry on low heat
The tumble dryer is the best tool for the job. Place the jacket in the dryer on a low heat setting (or “delicate”) along with the tennis balls or dryer balls. They bounce around, break up clumps and push air through the filling.
Expect the process to take two to three hours, sometimes longer for a thick coat. Stop every 30 minutes or so to take the jacket out, shake it, and manually break up any lumps with your fingers before putting it back. High heat can melt the shell fabric and damage the lining, so resist the urge to speed things up.
Air-drying if you do not have a dryer
If you cannot use a dryer, lay the jacket flat on a clean towel or a drying rack in a warm, airy room. Avoid direct radiators and strong sunlight. Turn it over and fluff it by hand every hour or so. This can take 24 to 48 hours, so start early in the week, and do not wear the jacket until it is completely dry, including the seams and cuffs. In a damp London winter, a dehumidifier or a well-ventilated airing cupboard helps a lot.
Down jacket clumping fix
If your down is still lumpy after washing, do not panic. Clumping almost always means the filling is still slightly damp or has not been broken up. Here is a reliable down jacket clumping fix:
- Run it through the dryer again on low heat with fresh dryer balls for another 30 to 60 minutes.
- Break clusters apart by hand. Gently pull each lump into smaller pieces and shake the jacket vigorously.
- Check for hidden moisture. Squeeze a baffle; if it feels cool or damp, keep drying.
- Rinse again if the lumps feel slick or soapy. This points to leftover detergent. Rewash with only water and an extra rinse, then dry as above.
Patience is the secret. Nine times out of ten, a thorough second dry restores the loft completely.
How to Wash a Ski Jacket
If you are heading to the Alps or Scotland from London this winter, you will want to wash ski jacket layers with extra care, because ski jackets combine insulation with waterproof, breathable membranes.
- Check the label. Many ski jackets have synthetic insulation rather than down, but the principles are similar.
- Use a technical wash, not standard detergent. Regular detergents can clog the membrane’s pores and reduce breathability.
- Wash on a cool, gentle cycle and rinse thoroughly.
- Dry on low heat. A short tumble can also help reactivate the water-repellent coating (often called DWR).
- Reproof if water no longer beads on the surface. A spray-on or wash-in reproofing product restores the finish.
Before a trip, it is worth cleaning your ski jacket once the season is over rather than leaving sweat and sunscreen in the fabric all summer. Perspiration salts can degrade fabrics and cause odours, and a jacket stored dirty is more likely to have trouble the following year.
How to Remove Stains from a Puffer Jacket
Stains are inevitable. Whether it is a splash of coffee, a smear of make-up on the collar or grease from a bike chain, the quicker you act the better. Here is how to remove stains from a puffer jacket without harming the shell or the filling.
- Blot, do not rub. Rubbing pushes the stain deeper and can damage the fabric.
- Use a mild cleaner. Dab a little down wash or a tiny drop of gentle liquid soap onto the mark with a clean cloth or soft toothbrush.
- Work from the outside in to avoid spreading the stain.
- Rinse with a damp cloth, removing all soap.
- Test first. Try any treatment on a hidden area (such as inside the hem) before using it on a visible one.
- Avoid bleach and harsh stain removers. They can strip colour and weaken shell fabrics.
Different stains need slightly different treatment:
- Oil and grease: sprinkle a little cornflour on the mark to absorb it, leave for 20 minutes, brush off and then spot-clean.
- Make-up and sweat marks around collars: gentle soap and a soft brush, working lightly.
- Ink and red wine: these set quickly and are best left to a specialist.
If the mark does not shift, or the jacket is expensive, pale or delicate, leave it to the experts. Our dedicated stain removal service pre-treats every mark according to the fabric and what caused it, so tell us what happened when you drop the coat off and we will choose the right approach.
How Often to Wash a Puffer
One of the most common questions we hear is how often to wash a puffer. The honest answer is: less than you think, but more than most people do.
- Light, occasional use (weekend wear, short walks): once a year, at the end of winter before storing.
- Daily commuting: once or twice per season, as sweat, pollution and body oils build up.
- Heavy outdoor use (skiing, hiking, cycling): after any particularly muddy or sweaty trip, and at least once per season.
Washing too often is not ideal either, because repeated washing and drying can gradually wear down the shell fabric and water-repellent finish. Between washes, spot-clean marks, air the jacket on a hanger on dry days, and wipe the collar and cuffs.
A simple rule: if the jacket smells, looks flat or feels noticeably less warm, it is time. Always give it a clean before long-term storage, since body oils can attract moths and mould.
Common Mistakes to Avoid
- Using normal detergent or fabric softener. Both coat the feathers and ruin the loft.
- Washing in a top-loader with an agitator. It can strain and tear the baffles.
- Using hot water or a hot dryer. Heat can damage the shell, the seams and the insulation.
- Skipping the extra rinse. Leftover soap causes clumping and dullness.
- Wearing or storing the jacket while slightly damp. This leads to odours and mildew.
- Hanging a wet jacket. The weight pulls the filling down and stretches the stitching.
- Squashing it in a compression sack for months. Store it loosely in a breathable bag to keep the down lofty.
When to Choose Professional Cleaning in London
Home washing works well for many jackets, but there are times when a professional clean is the safer, easier choice:
- The care label says dry clean only.
- The jacket has fur trim, leather panels or special finishes.
- It is an expensive, designer or heirloom piece.
- You have a stubborn stain such as ink, wine or grease.
- You do not have a large enough machine or a tumble dryer. This is very common in London flats, and a bulky wet coat is hard to dry without one.
- You simply do not have the time.

Frequently Asked Questions
Is it worth learning how to wash a down jacket yourself?
Yes, for most jackets. With a front-loading machine, a down-specific wash and a tumble dryer, you can get excellent results at home and save money. For delicate, expensive or dry-clean-only coats, a specialist is the safer option.
Can you machine wash a down jacket with other clothes?
It is best not to. A down jacket needs plenty of room and a gentle cycle, and other items can cause friction, unbalance the drum or leave lint on the shell.
How long does it take to dry a down jacket?
In a tumble dryer on low heat, allow two to three hours, sometimes more. Air-drying flat can take one to two days. It must be completely dry before you wear or store it.
Why does my puffer look flat after washing?
Usually it is still damp inside, or there is detergent left in the filling. Dry it again with dryer balls and, if it still feels slick, rewash with an extra rinse.
Can I use fabric softener on a puffer coat?
No. Fabric softener coats the feathers and reduces their ability to trap air, which makes the jacket less warm.
Do I need to wash a ski jacket differently from a down coat?
Slightly. Use a technical wash that protects the waterproof membrane, keep the heat low, and reproof the surface when water stops beading.
Final Thoughts
Knowing how to wash a down jacket turns a tired, flat coat back into the warm, lofty one you bought. Check the label, use a front-loader or a gentle hand wash, choose down-specific detergent, rinse twice, and take your time over drying. Treat stains quickly, wash only when needed, and store the jacket loosely so the down can breathe.
And when a coat is too precious, too stubborn or too bulky for your washing machine, we are happy to help. Bring your jacket to Elegance Dry Cleaners at 180 Northcote Road, London SW11 6RE, or ask about our free collection and delivery, and let us give your winter coat the care it deserves.
