How to wash a down jacket without ruining it

Knowing how to wash a down jacket keeps it warm for many winters. Over time, body oils, sweat and dirt coat the fine clusters of down, which then clump together and lose their loft, the fluffy volume that traps warm air. A careful wash restores that loft; a careless one can leave you with a flat, lumpy jacket.

The good news is that most down jackets can be washed at home in a washing machine. The key points are a gentle cycle, the right detergent, thorough rinsing and, above all, patient drying.

Check the care label first

The care label is the final word. Most down jackets can be machine washed on a gentle cycle at a low temperature, often 30 °C, but some have leather trims, fur, special coatings or delicate outer fabrics that need different treatment. If the label says dry clean only, take it to a cleaner experienced with down, since some solvents can strip the natural oils that keep down lofty.

If the jacket is very old or valuable, or has visible tears, repair small holes first or ask a specialist, because a wash can pull out more feathers.

How often should you wash a down jacket?

Less often than you might think. For most people, once or twice a season is enough, or whenever the jacket looks grimy, smells or feels flatter than usual. Frequent washing wears the fabric. Between washes, spot clean marks on the collar and cuffs with a damp cloth and a little mild soap, and air the jacket after heavy use.

When you think the down is dry, give it a few more hours.

What detergent to use on down

Use a detergent made for down or a very mild, non-biological liquid detergent in a small amount. Ordinary powders and strong detergents can strip the natural oils in down and leave residue that stops the clusters from lofting.

Avoid fabric softener, bleach and stain removers. Fabric softener in particular coats the down and the outer fabric, reducing loft and water repellency. Clean the detergent drawer beforehand so old residue does not end up in your jacket.

How to wash a down jacket in the washing machine

A front-loading machine is the best choice. Top-loaders with a central agitator can twist and tear the baffles that hold the down in place, so wash by hand or use a laundrette front-loader instead.

• Empty all pockets and close zips, poppers and hook-and-loop tabs.
• Loosen any drawcords and turn the jacket inside out if the label suggests it.
• Wash the jacket on its own, or with one other down item at most, so it can move freely.
• Add the down detergent in the amount shown on the bottle.
• Choose a gentle, delicate or wool cycle at a low temperature, usually 30 °C.
• Add an extra rinse to remove all detergent.
• Use a low to moderate spin to remove water without stressing the seams.

How to hand wash a down jacket

Fill a bathtub or large basin with lukewarm water and dissolve the detergent. Submerge the jacket, press out the air and gently squeeze the soapy water through it for a few minutes. Leave it to soak for around 30 minutes, then drain and refill with clean water. Rinse by pressing repeatedly until no suds appear, which can take several changes of water.

Never wring or twist a wet down jacket. Press water out by rolling it gently or pushing it against the side of the tub, and support its weight when lifting, since wet down is heavy and can tear the inner baffles.

How to dry a down jacket with dryer balls

Drying is the step that makes or breaks the result. Down must dry completely, otherwise it can clump, smell musty or develop mildew. The easiest method is a tumble dryer on low heat, if the care label allows it.

Add two or three clean dryer balls or tennis balls. As they bounce around, they break up clumps and help the down fluff up. New tennis balls can transfer colour, so wrap them in clean socks. Dry on a low setting, and every 20 to 30 minutes take the jacket out, feel for clumps and gently pull them apart with your fingers. A full dry often takes a few hours. High heat can damage synthetic outer fabrics and melt trims, so keep it low and be patient.

Without a dryer, lay the jacket flat on a drying rack in a warm, well-ventilated room, away from direct heat such as radiators or open flames. Turn it and break up clumps several times a day. Air drying can take a couple of days. When you think it is dry, give it a few more hours: moisture hides deep inside the down.

Restoring water repellency and storing your jacket

Many down jackets have a durable water-repellent finish on the outer fabric. If water no longer beads up, a wash-in or spray-on reproofing product for technical outerwear can restore it. Some finishes are reactivated by gentle heat in the dryer, so check the label.

Store a clean, fully dry jacket hanging loosely or in a large breathable bag. Compression sacks are fine for travel, but long-term storage in a tight bag crushes the down and reduces loft.

Frequently asked questions

Washing a down jacket at home is simple once you respect three rules: gentle washing, thorough rinsing and complete drying. Check the label, use a mild down detergent, skip the fabric softener and give the dryer and the dryer balls time to do their work. Your jacket will come out cleaner, loftier and ready for another cold season.
