Knitwear does the heavy lifting in a Sydney winter wardrobe. Wool jumpers, cashmere pullovers and merino layers are worn again and again through the cooler months — and they are also the pieces most likely to end up bobbly, misshapen or accidentally shrunk. Almost every one of those problems comes down to a handful of small habits at wash and dry time, which is what this guide to wool jumper care in Sydney covers.
Understanding how knit fibres behave makes it simple. Wool is a natural protein fibre covered in microscopic scales. Heat, agitation and sudden temperature changes make those scales lock together — that is felting and shrinking. Treat wool gently, however, and it stays soft and true to size for years — good wool jumper care in a Sydney winter is mostly restraint.
Pilling is the little balls of fibre that gather where a jumper rubs against itself, a bag strap or a coat. It is not a sign of poor quality — even good wool and cashmere pill, especially when new. To reduce it: turn jumpers inside out before washing, wash knitwear separately from rough fabrics like denim and towels, and avoid overloading the machine. When pills appear, do not pick at them; glide a fabric comb gently across the surface instead.

Shrinking almost always comes from heat plus agitation. The classic disaster is a warm wash followed by a tumble dryer — the jumper emerges felted and rigid, and once wool has felted the change is permanent. So the single most protective rule is: keep wool away from the tumble dryer entirely. Air drying is not just gentler; for knitwear it is essential.
Hanging a wet jumper is the fastest way to stretch it — gravity drags waterlogged fibres down until shoulders sag. Instead, lay the jumper on a clean towel, reshape it gently while damp, roll the towel to press out water, then dry flat on a fresh towel or mesh rack. Keep it out of direct sun and away from heaters. In a damp Sydney winter, airflow matters — a fan nearby prevents the musty smell of slow indoor drying.
Here is the best-kept secret: wash knitwear far less often than you think. Wool is naturally antibacterial and resists odour, so a jumper worn over a shirt can go many wears between washes — and every wash, however gentle, stresses the fibres. Between washes, air pieces overnight and spot-clean small marks. When cashmere or a structured knit does need a proper clean, our dry cleaning service handles delicate fibres safely, and knits ride along with any laundry pickup.
No — heat and tumbling felt the fibres permanently. Always dry knitwear flat, away from heaters and direct sun.
Most cashmere is safest professionally cleaned — the fibre is delicate and easily felted. Check the label, and when in doubt send it in.
Use a fabric comb or de-pilling tool with light strokes. Never pick pills off by hand — that pulls and weakens the knit.
Less than you think — wool resists odour naturally. Air between wears and wash only when genuinely needed; it extends the life of the garment.
