Cashmere and wool garments can last decades with the right care — or wear out in two seasons with the wrong one. The single most important rule: wash them less than you think you should. Both fibres are naturally self-cleaning, antimicrobial, and odour-resistant. Most cashmere and wool pieces need washing once or twice a season at most. Beyond that, you damage the fibre.
This guide covers the practical methods for keeping your Pianizzo knitwear in condition: how often to wash, how to wash, how to store, and how to handle the small problems (pilling, snags, moths) that come with natural fibres.
Most premium cashmere and wool pieces should be washed only when visibly soiled or when they no longer feel fresh after airing. As a baseline:
Between washes, hang the piece in a well-ventilated space for 24 hours. This restores the fibre's natural loft and removes most surface odours. Steaming on low setting refreshes the fabric without water exposure.
Modern washing machines with a wool or hand-wash cycle can be used carefully. Always place the garment in a mesh wash bag to reduce friction. Use cool water (max 30°C), low spin speed, and wool detergent. Lay flat to dry — never tumble dry.
Wool is more forgiving than cashmere but follows similar principles. Hand wash in cool water with wool detergent. Machine wash on wool/hand-wash cycle in a mesh bag if needed. The critical rule: never expose wool to heat — not in water, not in drying, not in pressing. Heat causes the fibre's surface scales to lock together (felting), which is irreversible.
Pilling — the small balls of fibre that form on the surface — is normal in the first few wears of any wool or cashmere garment. It's not a defect; it's the loose fibres separating from the yarn. After the initial period, pilling decreases significantly.
To remove pills:
Always lay the garment flat and work in one direction. Do not pull pills off by hand — you'll pull connected fibres and create snags.
Most wool and cashmere damage happens in storage, not in wearing. Two rules:
For off-season storage:
Clothes moths are the primary enemy of stored wool and cashmere. They lay eggs in natural fibres; the larvae eat the fabric, creating holes. Prevention is the only realistic defence.
A small snag is not the end of a sweater. Use a darning needle to pull the snag back through to the inside of the garment — never cut it. For small holes (less than 1cm), a darning service or a careful at-home repair with matching yarn can restore the piece invisibly. Most premium menswear retailers offer repair services for their own products; check before assuming a piece is beyond saving.
Yes, with caution. Use a mesh wash bag, wool/hand-wash cycle, cool water (max 30°C), wool detergent, and low spin. Always lay flat to dry. Hand washing is gentler but properly executed machine washing is acceptable for most pieces.
Act immediately. Blot (don't rub) with a clean cloth. For oil-based stains, sprinkle talcum powder or cornstarch to absorb the oil before washing. For protein stains (blood, dairy), use cool water only — heat sets these stains permanently. For wine or coffee, dab with cool water and wool detergent. If the stain doesn't lift in initial treatment, take it to a specialist dry cleaner experienced with wool and cashmere.
Yes, partially. Wash in cool water with wool detergent, then lay flat on a dry towel and reshape to the original dimensions. Press gently from the centre outward to compress slightly. Air dry. This won't fully reverse heavy stretching, but it will restore moderate distortion.
With proper care, 10–20 years. The fibres themselves are exceptionally durable; what wears out is poorly executed seams and badly handled fabric. A well-constructed Pianizzo cashmere piece, washed only when needed and stored properly, should outlast multiple wardrobe cycles.
Frequent dry cleaning is bad — the chemicals strip natural oils and shorten fibre life. Occasional dry cleaning (once or twice a year, for emergency stain removal) is fine. For routine cleaning, hand or machine wash with wool detergent is better than dry cleaning.
Initial pilling is normal in the first 5–10 wears and washes. It's the result of loose fibres separating from the yarn — not a defect. Use a cashmere comb to remove pills after the first few wears, and pilling will decrease dramatically. Persistent heavy pilling beyond the first season may indicate lower-quality fibre.
The Pianizzo knitwear collection is built in Italian 100% cashmere and premium merino wool, constructed for longevity. Follow the care methods above and your pieces should age into the wardrobe rather than out of it.
