How to Store Cashmere

Prevent moths, avoid damage, and keep every piece in perfect condition.

Most cashmere damage happens not during wear, but during storage. A sweater can be washed correctly and handled gently, then still be ruined by months in the wrong environment.

This guide covers the full storage system: prep before storage, folding vs hanging, moth prevention, container choice, in-season rotation, and recovery steps if damage appears.

Why Storage Is Where Most Cashmere Gets Damaged

Cashmere is a protein fiber. It performs well in normal wear, but storage introduces specific risks that are easy to miss.

The Three Threats to Stored Cashmere

• Physical distortion from hanging
• Moth damage from larvae feeding on keratin
• Humidity and compression that flatten loft and encourage mildew

Physical distortion is caused by gravity pulling on knit loops over time. Moth damage is biological and often discovered late. Humidity and over-compression reduce softness and shape recovery.

Before You Store: Always Wash First

Always wash cashmere before long-term storage, even if it looks clean.

Moths are attracted to organic residue: body oils, skin cells, perspiration, and food traces. A "clean-looking" sweater can still be highly attractive to larvae over a six-month storage period.

Pre-Storage Preparation Checklist

1. Wash with a cashmere-safe method and detergent.
2. Rinse thoroughly.
3. Dry fully, flat, and completely.
4. Air at room temperature for a few additional hours.
5. Inspect for holes, weak spots, and signs of infestation.

Why This Step Is Non-Negotiable

• Organic residue feeds moth larvae
• Invisible soiling is enough to trigger infestation
• Seasonal storage duration allows full moth lifecycle development

Folding vs Hanging: Not a Grey Area

Cashmere should be folded for storage. Never hung.

Knits are loop-based and elastic. Long-term hanging creates shoulder points, sleeve elongation, and body drop from continuous gravity load.

How to Fold Cashmere Correctly

1. Lay garment flat and smooth gently.
2. Fold sleeves across the back.
3. Fold lengthwise to reduce width.
4. Fold from hem upward in halves or thirds.
5. Place fold side down in stack.
6. Keep stack height moderate (around 3 to 4 pieces max).

Understanding Clothes Moths

Adult clothes moths do not eat the garment. Larvae do.

Larvae feed on keratin in cashmere and wool, especially in warm, dark, undisturbed storage with organic residue present.

Conditions Moths Need

• Warmth
• Darkness
• Low disturbance
• Food source (soiled fibers)

Moth prevention works by removing these conditions as much as possible.

Moth Prevention: What Works and What Does Not

Best Storage Containers for Cashmere

Airtight zip storage bags

Best for long-term storage. Seal well, but avoid extreme vacuum compression that crushes fiber loft.

Breathable cotton/linen bags

Useful for short-term and easy access. Better airflow, but less protection than sealed storage.

Lidded storage boxes

Excellent for folded stacks. Add fresh cedar/lavender. Acid-free boxes are best for premium pieces.

Drawers and shelves

Good for in-season storage only, when garments are handled regularly.

Avoid These

• Standard non-archival cardboard for long-term storage
• Generic plastic bags that trap moisture
• Any long-term hanging setup
• Storage near radiators, heated floors, or direct sun

Between-Season Storage: Step-by-Step

1. Inspect every piece in bright light.
2. Wash all worn pieces before storage.
3. Dry fully flat and air out.
4. Fold carefully without hard compression.
5. Add fresh cedar/lavender to container.
6. Place pieces loosely and avoid overfilling.
7. Seal and label with storage date.
8. Store cool, dry, dark, and stable.

Seasonal Storage Checklist

• All pieces washed and fully dry
• Repellents fresh and fragrant
• Pieces folded, never hung
• Containers sealed and labeled
• Storage environment cool, dry, dark

In-Season Storage: Between Wears

During active wear months:

• Rest each piece at least 24 hours between wears
• Air each piece for 1 to 2 hours after use
• Fold between wears rather than hanging
• Treat spills and stains quickly

These habits reduce pilling, preserve shape, and lower moth risk.

What to Do If You Find Moth Damage

Act quickly to stop spread.

1. Remove all items from the affected area.
2. Bag exposed items and freeze at -18C for at least 72 hours.
3. Vacuum and clean shelves, corners, and seams thoroughly.
4. Wash or professionally clean all exposed garments.
5. Re-store with fresh repellents and monitoring.

Small holes may be repairable by specialist invisible menders, but prevention remains the primary defense.
