Washing Winter Clothes After the Season: The Complete Guide

As spring arrives, your winter wardrobe goes into storage until next season. But if you simply shove your clothes into the wardrobe, next autumn you'll find an unpleasant surprise – yellow sweat stains, mould, moth damage, odours. Preparing them properly takes 1-2 hours, but it will save your expensive winter clothes. In this article: a complete guide to washing and preparing winter clothes by type, and how to store them the right way.

Why you must wash clothes before storing them

Many people think that if a garment "looks clean", there's no need to wash it. That's a mistake. Over the winter season, a garment builds up:

• Sweat – invisible, but after 6-8 months in storage it turns into yellowish stains
• Body oils – which attract moths and mould
• Food and drink residue – even tiny traces you can't see will become a breeding ground for mould
• Deodorant residue – which turns into yellow stains during storage
• Food smells – which can leave a lingering odour

The golden rule: all clothes must be clean and completely dry before going into storage.

Washing coats and jackets by type

Feather / down jacket

The most expensive and the most delicate. A careful wash takes time, but it's essential:

1. Check the care label – most modern down jackets are machine washable
2. Close the zips and fasten the poppers (so they don't damage the fabric)
3. 30 °C, delicate cycle
4. A dedicated down wash, or a reduced dose of enzyme laundry detergent (15 ml)
5. No fabric softener
6. 2 extra rinses
7. Low spin speed
8. Drying: in a tumble dryer with 3-4 wool dryer balls (low heat), or flat in a well-ventilated room for 2-3 days, shaking it every few hours

The critical step is drying it completely. Damp feathers go mouldy within a few days in the wardrobe.

Synthetic puffer jacket (polyester filling)

Easier than down:

1. Close the zips
2. 30-40 °C (depending on the care label)
3. Enzyme laundry detergent at the standard dose
4. No fabric softener
5. An extra rinse
6. Dry in a ventilated room for 1-2 days, or in a tumble dryer (low heat)

Wool coat

The classic everyday winter garment. For most wool coats:

1. First, spot-clean any visible stains
2. A short coat (140-150 cm) can be washed at home on the "wool" cycle at 30 °C with a wool detergent
3. A long coat should go to the dry cleaner's
4. Without dry cleaning: air it in the sun for 4-6 hours
5. Brush the wool to remove surface dirt

Ski / technical jacket (GORE-TEX, membrane)

Needs specific care. Find out more about technical clothing in our guide to washing sportswear.

1. A dedicated technical fabric cleaner (Nikwax, Granger's)
2. 30 °C, delicate cycle
3. No fabric softener (it clogs the membrane)
4. An extra rinse
5. Consider renewing the water repellency (DWR re-treatment) before storage

Leather jacket

Never put it in the washing machine. Here's what to do:

1. Remove dust with a dry brush
2. Wipe the surface with a damp cloth (without soaking it)
3. Apply a dedicated leather cream / conditioner
4. Store it somewhere ventilated, not in an airtight plastic bag

Washing jumpers

Wool jumpers

1. Wool detergent (NOT an enzyme detergent – proteases damage wool)
2. 30 °C, "wool" or "delicate" cycle
3. Low spin (max 600 rpm)
4. Dry flat (hung vertically, a jumper stretches under its own weight)
5. Ideally on a towel, repositioning it a few times

Cashmere

A premium, delicate fibre:

1. Best washed by hand in warm (not hot) water
2. A dedicated cashmere wash
3. Never pull or wring it
4. Press the water out – don't twist
5. Dry flat on a towel

Acrylic / synthetic jumper

1. 30 °C, enzyme laundry detergent
2. Standard or delicate cycle
3. Medium spin
4. Can be air-dried hanging up (lighter than wool)

Washing hats, scarves and gloves

Wool / cashmere accessories

The same rules as for jumpers – wool detergent, 30 °C, gentle cycle.

Knitted accessories

Check the yarn label. For most – 30 °C on a gentle cycle.

Leather gloves

Never in the washing machine. Wipe the surface with a damp cloth and use a dedicated leather cream. Store somewhere ventilated.

Synthetic winter gloves

30-40 °C, enzyme laundry detergent, standard cycle. You can turn them inside out so the insides dry thoroughly.

Winter boots – a separate topic

Don't wash boots in the washing machine (with rare exceptions for trainers). But before storing them:

1. Remove the insoles – wash them separately (in the machine at 30 °C)
2. Wipe the inside with a damp cloth
3. Dry the boots out with newspaper or dedicated boot shapers (to hold their shape)
4. Treat leather with shoe cream
5. Store them in their original boxes or in fabric bags – not in plastic bags

Storage rules

Even a perfectly washed garment will lose its quality if stored incorrectly. The key rules:

1. Dry completely

Allow at least 24 hours after washing before putting clothes into storage. Air thick garments thoroughly – even if they seem dry.

2. A ventilated space

A wardrobe or box needs air circulation. In an airtight plastic bag, clothes start to smell within 1-2 months.

3. Keep them out of the light

Direct sunlight gradually fades colours, even inside a wardrobe. A closed wardrobe is best.

4. Moth protection

Winter clothes (especially wool) are a moth's favourite target. Protection options:

• Lavender sachets (a natural repellent)
• Cedar shavings or cedar blocks
• Essential oils (lavender, cedar) on cotton wool balls
• Commercial moth repellents (with care – many have strong scents)
• Mothballs – effective, but they smell strongly and can be toxic in households with children

5. The right temperature and humidity

Ideally 15-22 °C with 40-50% humidity. Too damp – mould. Too dry – brittle fibres.

6. Vacuum bags – yes and no

Vacuum bags save space, but:

• They're NOT suitable for feather and down jackets (compression damages the feathers)
• They're fine for synthetic jumpers and jackets
• Wool – fine, but not for long (wool needs to "breathe")

7. Original boxes

Premium garments (cashmere, fine trousers, expensive coats) are best stored in their original boxes or in fabric – natural cotton bags.

Special cases

A garment with mould stains

Never put it into storage – the mould will keep growing and spread to neighbouring clothes. Find out more in our guide to removing mould stains.

A garment with yellow sweat stains

During storage, the stains will become much more stubborn. Remove them before storing – see our guide to sweat stains.

An expensive garment

Consider dry cleaning before storage – for a premium garment, the investment pays for itself through a longer lifespan.

Vintage and antique pieces

A category of its own. Consult an antiques specialist – the wrong washing method can reduce their value.

A spring checklist

A practical step-by-step plan:

1. Gather all your winter clothes in one place
2. Sort them by condition: to wash / to dry clean / to throw away
3. Check each item – buttons, zips, linings. Repair anything that needs it
4. Wash them or send them to the dry cleaner's following the rules above
5. Dry them completely (24+ hours)
6. Hang them up or store them in boxes
7. Add moth protection
8. Label the boxes ("Winter jumpers 2026" and so on) – it'll help you find things faster next autumn

The whole process takes one Saturday. But your winter wardrobe will last much longer, and you'll be ready for next season.

Frequently asked questions

Do I need to wash a garment I've only worn a few times?

Yes. Even a garment worn a handful of times carries sweat and body oils that mould and moths will find over 6 months of storage. Don't trust your eyes – wash it.

Can jumpers be stored on hangers?

No, especially wool and cashmere. The weight resting on the narrow point of the hanger stretches the jumper, particularly over 6 months. Store them folded in boxes or on shelves.

Coats and jackets on hangers – yes or no?

Synthetic puffers and technical jackets – yes, on a wide, sturdy hanger. Down jackets are better folded in a box, because on a hanger the feathers "slide" downwards.

How can I tell if a garment is completely dry?

Press your hand into the thickest part (the sleeves, the chest). If it feels cold or damp, it isn't dry yet. A fully dry garment feels "room temperature".

Do families with children really need mothballs?

No. Mothballs can cause respiratory problems and are toxic in larger quantities. Lavender and cedar are enough in most cases.

Summary

Storing winter clothes properly in spring is an investment that pays off for several seasons running. The key rules: wash EVERYTHING before storing it (even what "looks clean"), use the right method for the material (wool, down and synthetics each have different rules), dry everything completely (24+ hours), and store clothes in ventilated spaces with moth protection.
