How to clean, pack and store woolens, shawls, suits and winter wear correctly — so they come out next season exactly as they went in. With specific advice for India’s long hot storage period and Kolkata’s monsoon humidity.
Why you must clean before storing
This is the single most important rule of winter clothes storage and the one most often ignored. Every garment worn this winter — even one worn just once for a few hours — carries residue that will cause permanent damage during the storage months.
What is on an unwashed garment: sweat and skin oil absorbed into the fibres, food residue from meals, perfume and deodorant residue, atmospheric dust, and body heat condensation. None of this is visible to the naked eye after the garment has dried. But all of it is present.
What happens during storage: In the dark, in warmth, over 7–8 months, these residues do three things. They oxidise — causing yellowing and browning that becomes permanent. They attract clothes moths and carpet beetles, which feed on the protein residue, not the clean fabric. And they weaken the fibre structure of wool, causing it to become brittle in the areas of heaviest contamination.
The rule is absolute: Dry clean woollen suits, blazers, shawls, pashmina and structured knitwear before storing. Wash cotton and synthetic winter wear before storing. No exceptions. A garment that looks clean is not necessarily clean at the fibre level.
Fabric by fabric — how to store each
Different fabrics have different storage requirements. The common thread is clean first, breathable wrapping, and darkness.
Never fold a tailored garment. The canvas and interlining compress permanently under sustained pressure. Hang on a wide padded wooden hanger. Store in a breathable cotton garment bag — never a sealed plastic dry cleaning bag. Allow space around it.
Fold, never hang. The weight of a hanging pashmina stretches the fibres over months. Fold with acid-free tissue between layers. Wrap in undyed muslin. Store flat in a drawer or box. Handle with clean hands — skin oil transfers to pashmina easily.
Never hang knitwear. The weight of a hanging wool sweater permanently stretches the shoulder seams over a 7-month storage period. Fold flat and stack. Fine Merino and lambswool — dry clean. Coarser knitwear — hand or machine wash on wool cycle before storing.
Dry clean only — no exceptions. Wrap in undyed cotton muslin. Never plastic. Store flat. Refold along different lines each year to prevent permanent crease marks. Full silk saree storage guidance at our silk saree guide.
Ensure completely dry before storing. A damp blanket stored in a bag will develop mould within weeks in Kolkata’s heat. Roll loosely or fold with airflow. Store in a breathable bag or muslin-lined box with cedar blocks.
Synthetic and mixed-fibre jackets can usually be machine washed. Check care label. Structured jackets with shoulder padding — dry clean and hang. Unstructured puffer or fleece jackets — wash and fold or loosely roll.
The storage method — step by step
Once cleaned, the method of storage determines what condition the garment will be in when you bring it out next season.
Moth protection — the real threat to stored wool
Clothes moths (Tineola bisselliella) and carpet beetles cause more permanent damage to stored winter clothes in India than any other single factor. Understanding how they work makes protection straightforward.
What they eat: Not the clean fabric itself — the protein residue on uncleaned garments. Sweat, food residue and skin oil on wool are what attract insects to a stored garment. A completely clean garment is significantly less vulnerable.
What they damage: The larvae — not the adult moth — eat the fabric. They create small, irregular holes, often in areas of heaviest sweat residue (underarms, collar, cuffs). By the time you see the adult moth flying around, the damage is already done and months old.
What works:
Cedar blocks — replace annually as the oils evaporate. Dried neem leaves — replace each season. Lavender sachets — mild but effective, pleasant smell. All should be placed near but not touching fine fabrics — direct contact can leave oil marks on pashmina and fine wool.
What does not work as expected:
Naphthalene mothballs — effective but the chemical vapour damages wool fibres over time, leaves a persistent smell that is very difficult to remove, and is toxic. Do not use against fine wool or pashmina. Sealed plastic bags — the absence of air does not deter moths; eggs laid before sealing will hatch regardless. And plastic traps moisture, creating secondary mould damage.
Kolkata’s year-round warm temperatures — rarely below 15°C even in winter — mean clothes moths are active almost all year. Monthly inspection of stored winter wear during the storage period is advisable in Kolkata, not just once in the middle of summer. If moth damage is found, dry clean the affected garment immediately and dry clean all nearby stored wool as a precaution before returning to storage.
Storing winter clothes in Kolkata’s climate
Kolkata’s climate presents a specific and severe challenge for winter clothes storage that is unlike most other Indian cities. The storage period is long — typically February or March through October or November — and passes through three distinct climate phases, each of which threatens stored garments differently.
The monsoon is the critical period. Wool is hygroscopic — it absorbs atmospheric moisture readily. A wool sweater stored in a room with 85% humidity absorbs that moisture, creating a micro-environment within the storage bag that encourages mould. In severe cases, mould on wool can cause permanent fibre damage within a single monsoon season.
Practical steps for Kolkata storage: Use silica gel desiccant packets in the storage location — not just inside bags, but in the wardrobe or storage room itself. Replace them monthly during June–September. Consider a small dehumidifier in the storage room if it is prone to monsoon dampness. Inspect stored garments in July — the midpoint of the monsoon — to catch any mould early.
On return from storage: When bringing winter clothes out in October or November, air every garment in shade for a full day before wearing. The storage room may have absorbed monsoon humidity even if the garments appear dry. Airing removes any residual mustiness and allows the fabric to equilibrate to the lower post-monsoon humidity before being pressed and worn.
Returning to wear — what to do in October
How you bring winter clothes out of storage is as important as how you stored them. Garments that have been stored for 7–8 months need attention before they are worn.
Air before wearing: Hang or lay every garment in a well-ventilated, shaded location for at least 24 hours before wearing. Do not bring out of storage directly to the wardrobe. The fabric needs to breathe after months in a sealed environment.
Inspect carefully: Check every garment for moth damage (small irregular holes, often at collar or underarms), mould spots (grey or white surface marks, often with a musty smell), yellowing from sweat oxidation, or any staining that was missed before storage. Address any issue before wearing.
Dry clean before wearing if: The garment was stored for more than 6 months. The storage conditions were humid or uncertain. There is any odour, even faint. There are marks that were not visible when the garment was stored. The garment will be worn to an important occasion directly.
Book a dry clean and press: For winter occasion wear — wool suits, pashmina shawls, structured jackets — the best return-to-season action is a professional dry clean and press. The garment comes out of storage refreshed, any storage odour removed, pressed and ready to wear.

Common questions
Questions about
winter storage.
Dry clean or wash all winter clothes before storing. Wrap woollens in cotton muslin or breathable garment bags, not plastic. Place cedar blocks or dried neem nearby to deter moths. Store cool, dark and dry. In Kolkata, use silica gel desiccant during the monsoon.
Clean the garment first — moths are attracted to food residue and sweat, not clean wool. Store with cedar blocks, dried neem or lavender sachets nearby but not touching the fabric. Never use naphthalene mothballs against fine wool. Inspect every 3 months.
Yes — woollen suits, blazers, shawls, pashmina and structured knitwear must be dry cleaned before storage. Even garments that appear clean carry sweat and skin oil that attract moths and cause yellowing over months.
No. Plastic traps moisture, creating conditions for mould on wool protein fibres. Use cotton garment bags or muslin wrapping. If using a sealed box, include silica gel desiccant — especially important in Kolkata during the monsoon months.
Winter clothes stored correctly can last years without damage. The critical factors: clean before storing, breathable wrapping, moth deterrents, cool dark storage, and inspection every 3 months. In Kolkata, the 7–8 month storage period through summer and monsoon requires humidity control with silica gel.
October or November — once temperatures drop consistently below 25°C. Air every garment in shade for 24 hours before wearing. Inspect for moth damage, mould or yellowing. Dry clean and press if stored for 6 months or more.
