A step-by-step guide to washing baby cashmere and wool by hand, drying knitwear safely, and storing ponchos and blankets so they stay soft for the next child.

Quick answer

Wash baby cashmere and wool by hand in cool water with a pH-neutral wool detergent, then press the water out and dry the piece flat on a towel. Store clean, completely dry knitwear folded in a breathable cotton bag, never on a hanger.

Why baby knitwear needs a different wash routine

Wool and cashmere fibers have tiny scales that open in hot water and rub against each other in a machine drum, which is how a baby sweater turns into a doll-sized piece. A hand wash in cool water keeps those scales flat, so the garment holds its shape and softness. Because babies wear these pieces against the skin and often mouth their sleeves, you also want a detergent free of enzymes, bleach, and optical brighteners that can irritate delicate skin. A pH-neutral wool wash is the safest default; ordinary laundry detergent is too alkaline for protein fibers.

How to hand wash baby wool and cashmere

Fill a basin with cool water, add a capful of wool detergent, and submerge the garment without rubbing. Let it soak for five to ten minutes, then gently squeeze the suds through the fibers. Rinse in clean cool water until it runs clear. Never wring, twist, or hold a wet knit by the shoulders; support the whole piece with both hands when you lift it. If a stain needs attention, dab it with a little detergent before soaking rather than scrubbing afterward.

Drying without stretching or felting

Lay a clean towel on a flat surface, place the garment on top, and roll the towel up to press out excess water. Then unroll and reshape the piece on a dry towel or mesh drying rack. Keep it away from radiators, direct sun, and tumble dryers, because heat and agitation cause wool to felt and cashmere to pill. A baby poncho or blanket can take a full day to dry; turn it once after a few hours so the underside gets air.

Storing baby wool clothes between wears and seasons

Store only clean knitwear, because invisible milk or food residue attracts moths. Fold each piece rather than hanging it, since a hanger stretches shoulder seams and distorts a poncho’s neckline. Use a breathable cotton storage bag or a cotton pillowcase, and add a cedar block or lavender sachet if moths are a problem in your area. Keep the bag in a dry, dark cupboard; damp basements and hot attics both damage wool fibers over months. Before putting a piece away for the season, check that it is completely dry, then air it for an hour and refold it along different lines to avoid permanent creases.

Your step-by-step baby knitwear care routine

Check the label and spot-test: Read the care label before any water touches the garment. If it says dry clean only, follow that. For washable pieces, test a hidden hem with a drop of wool detergent and cool water. Checkpoint: if the color transfers to a white cloth, stop and take it to a professional cleaner.
Pre-treat stains without rubbing: Dab milk, food, or spit-up with a small amount of wool detergent and cool water using a clean cloth. Let it sit for five minutes. Never scrub, because friction felts the fibers. Mistake to avoid: using hot water on a protein stain, which sets it permanently.
Hand wash in cool water: Fill a basin with cool water and wool detergent. Submerge the piece and gently squeeze suds through it for a few minutes. Do not twist or wring. Checkpoint: the water should stay clear of heavy dye release; if it darkens quickly, rinse sooner.
Rinse and press out water: Rinse in clean cool water until no suds remain. Lift the garment with both hands, then lay it on a towel and roll the towel to press out water. Mistake to avoid: lifting a wet poncho by one corner, which stretches the neckline.
Dry flat and reshape: Place the piece on a dry towel or mesh rack away from heat and sun. Reshape the neckline, cuffs, and rolled edges while damp. Checkpoint: if the piece still feels cool and damp after a day, turn it over and let it air longer before storing.
Store folded in a breathable bag: Once fully dry, fold the garment and place it in a cotton bag or pillowcase with a cedar block. Store in a dry cupboard, not a damp basement or hot attic. Next step: refold along different lines every few months to prevent permanent creases.

How this applies to Bobine Paris ponchos

Poncho en laine et cachemire Bleu 4-6 ans: Poncho in merino wool and cashmere, blue, size 4-6 years, with a round neck and rolled-edge finish. The wool-cashmere blend responds well to the hand-wash method above, and the rolled edges should be reshaped flat while drying so they do not curl.
Poncho en laine et cachemire Perle pailleté 4-6 ans: Poncho in wool and cashmere with sequins, pearl color, size 4-6 years, with an easy pull-on style. Sequins can snag on other knitwear in storage, so keep this piece in its own cotton bag and avoid wringing near the embellishment.
