Answer: To wash cashmere safely, read the label, treat stains gently, hand‑wash in lukewarm water with a mild detergent, avoid wringing, dry flat, and store properly.

Cashmere feels like a cloud, but the wrong wash can ruin that softness. Follow these seven steps for a fool‑proof clean that keeps your designer pieces looking fresh.

Step 1: Read the Care Label

Start by checking the garment’s care label. The label tells you whether the piece is hand‑wash‑only, machine‑safe, or dry‑clean‑only. Ignoring it can lead to shrinkage or loss of shape.

Most cashmere sweaters recommend hand washing with a low‑pH, wool‑friendly detergent.

At CSD (Consigned Sealed Delivered) we authenticate every cashmere item before it reaches you, so you can trust the label is accurate. If you’re unsure, treat the piece as hand‑wash‑only.

Step 2: Pre‑Treat Stains Gently

Spot‑treat any visible stains before the full wash. Use a cotton swab dipped in a tiny amount of baby shampoo or a wool‑specific detergent. Gently dab the stain , don’t rub.

Rubbing creates friction that can felt the fibers, a risk highlighted by multiple experts. Let the solution sit for 15‑30 minutes, then rinse with cool water.

After pre‑treatment, place the sweater on a clean white towel to absorb excess liquid before the soak.

Step 3: Hand Wash Your Cashmere

Fill a clean basin with lukewarm water (below 30 °C/86 °F). Add a capful of baby shampoo or a wool‑safe detergent and stir gently.

Submerge the sweater and let it soak for 10‑15 minutes. Swirl lightly with your hands , avoid any rubbing or wringing. Minimal agitation protects the fine fibers.

Rinse in fresh lukewarm water until no soap remains. Press the water out by laying the sweater flat on a dry white towel and rolling the towel gently around it.

Step 4: Machine Wash on a Delicate Cycle (if label allows)

If the label explicitly permits machine washing, select a wool or delicate cycle with cold water. Add the same low‑pH detergent you used for hand washing.

Place the sweater inside a mesh laundry bag to guard against agitation. Run only the spin portion , most machines let you stop after the rinse.

When the cycle ends, remove the garment immediately to avoid prolonged moisture exposure.

Step 5: Dry Your Cashmere Flat to Maintain Shape

Never hang a wet cashmere sweater; the weight of the water will stretch the shoulders permanently.

Lay the garment on a clean, dry white towel, reshaping it to its original dimensions. If you have a drying rack, use it , the increased air flow speeds drying without crushing the fibers.

Turn the sweater over halfway through the drying period to ensure even airflow. Allow 24‑48 hours to dry fully at room temperature.

Step 6: Remove Pilling and Refresh Between Washes

Cashmere naturally pills over time. Use a cashmere comb or a fabric shaver to lift loose pills without pulling the yarn.

Between washes, give the garment a quick air‑out by laying it flat for a few hours in a well‑ventilated room. This refreshes the fibers and reduces odor.

For stubborn pills, a gentle brush in the direction of the knit works best , avoid harsh scraping that can damage the surface.

Step 7: Store Cashmere Properly

When the season ends, store cashmere folded, not hung. Place acid‑free tissue paper between folds to keep the shape.

Store in a breathable cotton bag with cedar balls or lavender sachets to deter moths. If you discover moths, freeze the item for 48 hours before re‑washing.

At CSD we keep each consigned piece in climate‑controlled storage, wrapped in cotton and protected with natural repellents, so your purchase arrives ready to wear.

How often should I wash my cashmere sweater?

Most experts suggest washing after seven to ten wears, or when the garment shows visible stains or odor.

Will baby shampoo damage cashmere?

How do I prevent my cashmere from shrinking?

Avoid hot water, harsh detergents, and any rubbing or wringing; always reshape and flat‑dry the garment.
