How to Store Clothes Long-Term
Always wash before storing. Body oils and sweat that are invisible on a fresh garment cause permanent yellowing over months. Clean in, clean out.
The most common seasonal storage mistakes are skipping a pre-wash and forgetting that moths only eat protein fibres — not cotton or synthetics. This guide covers what to do before storing, how to protect natural fibres from moths, what containers to use, and the fold vs hang question.
Before You Store Anything
Wash or dry clean everything before storing
This is the most commonly skipped step and the most important. Invisible body oils, sweat residue, and food particles that are undetectable on a garment fresh from wearing will oxidize over months and cause permanent yellow staining. What goes in clean comes out clean. What goes in with any residue often comes out damaged.
Ensure everything is completely dry
Any moisture trapped in storage — even from recent washing — creates mould and mildew. Garments should be worn, stored, or hung for at least 24–48 hours after washing before being folded into boxes or vacuum bags. This is particularly important in humid climates.
Repair before storing
Loose buttons, open seams, and small holes always get worse in storage. A small repair now takes minutes; finding it months later when you want to wear the item means more work, or a garment you no longer want to fix. Check everything before packing.
Moth Risk — Which Fabrics Are at Risk
Moths only eat protein fibres. Cotton, linen, and synthetics are safe — wool, cashmere, and silk are targets.
Wool
Primary target — moths specifically seek keratin (wool protein). Cashmere, merino, lambswool all at risk.
Cashmere
Highest risk — fine cashmere fibres are a preferred target. Store sealed with cedar.
Silk
Target — silk fibroin is a protein. At risk, especially raw or unprocessed silk.
Feather down and fur
At risk — protein materials. Seal and use cedar or cold storage.
Cotton and linen
Not a target — plant-based cellulose fibres contain no keratin. Safe without moth prevention.
Polyester and synthetics
Not a target — synthetic petroleum-based fibres. No moth risk.
Moth Prevention Methods
Cedar (blocks and hangers)
Effective and safeCedar wood contains natural oils that repel clothes moths. Cedar blocks, sachets, and hangers are safe for all fabrics including delicates. Effectiveness decreases as the oils evaporate — sand the cedar surface lightly with sandpaper every 6 months to refresh the scent. Cedar does not kill eggs already in fabric — it prevents moths from laying in the first place.
Lavender sachets
Mild repellent onlyLavender repels adult moths mildly but is less effective than cedar. Safe for all fabrics. Replace or refresh dried lavender annually as the scent fades. Best used as a supplement alongside cedar rather than as a standalone solution.
Mothballs (naphthalene or paradichlorobenzene)
Effective but not recommendedMothballs kill moths and larvae but release toxic vapour (naphthalene or paradichlorobenzene) that is harmful to humans and pets. The smell permeates fabrics and is very difficult to remove — many garments stored with mothballs need airing for weeks and sometimes the smell never fully leaves. The fabric also absorbs the chemicals. Avoid unless in a completely sealed, unventilated space with no human or pet access.
Sealed storage
Most reliableClothes moths cannot eat what they cannot reach. Clean garments stored in sealed plastic containers, vacuum storage bags, or sealed zipper bags are fully protected without any repellents. This is the most reliable method and the best option for valuable or irreplaceable items (cashmere, vintage, silk).
Cold storage
Kills eggs and larvaeMoths and their eggs die at temperatures below -8°C held for 72 hours or longer. If you suspect a moth presence in a garment, placing it in a sealed plastic bag and freezing for a week kills all stages of the lifecycle. Defrost slowly (bring to room temperature still sealed) to prevent condensation on the garment.
Storage Container Guide
Vacuum storage bags
Best for: Bulky items: duvets, winter coats, thick knitwear
Not suitable for delicates, silk, cashmere, or structured garments. Compression can permanently crease and distort fine or structured fabric. The airtight seal provides excellent moth and moisture protection for appropriate items.
Acid-free tissue and archival boxes
Best for: Luxury items, vintage garments, wedding dresses, silk, cashmere
Acid-free tissue prevents yellowing of natural fibres during long-term storage (ordinary tissue and cardboard are mildly acidic and cause yellowing over years). Fold tissue between each layer. Store in a cool, dark, dry location.
Breathable cotton or linen storage bags
Best for: Suits, structured garments, leather, items needing airflow
Allows airflow — prevents mildew from trapped moisture. Does not provide moth-proof protection on its own. Pair with cedar inserts inside the bag.
Plastic bins with lids
Best for: Casual off-season clothes, jeans, cotton knitwear
Good moisture and moth barrier when sealed. Avoid for items that need to breathe (leather) or are prone to compression creasing (structured garments). Label clearly.
Hanging garment bags
Best for: Suits, coats, formal dresses — items that must keep their shape
Fabric garment bags breathe; plastic ones trap moisture. For long-term storage, fabric garment bags with cedar inserts are better. Do not over-stuff a single bag.
Fold vs Hang — Quick Reference
T-shirts, cotton tops
Hanging stretches the shoulder and neckline over time.
Knitwear (wool, cashmere, cotton jumpers)
The weight of the garment stretches knit fabric if hung. Fold and stack.
Jeans and trousers
Folding avoids hanger crease across the thigh. Hang only if space allows and the crease is acceptable.
Dress shirts and blouses
Hanging prevents front placket wrinkling. Use a padded hanger for delicate fabrics.
Suits and blazers
Structured garments must be hung on shaped suit hangers to retain their form.
Silk and delicate dresses
Hang if the fabric holds its shape. Use a padded hanger — wire hangers create shoulder dents.
Coats and heavy outerwear
Hang on a sturdy hanger. Heavy coats stored folded develop permanent creases.
FAQ
How do you store clothes long-term without damage?
Always wash or dry clean garments before storing — invisible body oils and sweat oxidize during storage and cause permanent yellowing. Ensure everything is completely dry before packing. Store protein-fibre garments (wool, cashmere, silk) in sealed containers with cedar to protect against moths. Use acid-free tissue for luxury items. Keep storage cool, dark, and dry — heat, light, and humidity all accelerate fabric degradation.
Do moths eat all types of fabric?
No — clothes moths specifically target protein-based natural fibres: wool, cashmere, silk, feather down, and fur. They cannot digest plant-based cellulose (cotton, linen) or synthetic petroleum-based fibres (polyester, nylon, acrylic). If you have a moth problem, only your natural protein-fibre garments are at risk. Store them sealed with cedar or in airtight containers. Cotton and synthetics need no moth protection.
Are cedar balls better than mothballs?
Cedar is the better choice for almost all home use. Cedar wood oils repel adult moths safely without releasing toxic fumes, are safe for all fabrics and pets, and have no lingering smell that permeates garments. Mothballs (naphthalene or paradichlorobenzene) are more effective at killing larvae already present, but the vapour is toxic, the smell is very difficult to remove from fabric, and the chemicals absorb into the fabric. Cedar repels moths from laying in the first place; mothballs are a last resort for severe infestations.
Should you use vacuum storage bags for clothes?
Vacuum bags are excellent for bulky, low-value items: duvets, winter coats, thick jumpers. The compression and airtight seal protect against moths and moisture. However, vacuum bags are not suitable for delicates, silk, cashmere, or structured garments — compression causes permanent creasing and distorts fine fibres and garment shape. For anything valuable or delicate, use acid-free tissue in an archival box or a breathable fabric storage bag with cedar instead.
