A good knit is one of the most sustainable things in a wardrobe — provided it survives your washing machine. Wool is naturally odour-resistant, naturally crease-shedding and naturally built to last decades, yet more jumpers are lost to a hot wash and a tumble dryer than to any moth. Learning how to wash wool properly is less about effort and more about restraint: wool asks you to do far less than you think. With Bondi deep in its coastal winter and the knits out in force, this is the Tuchuzy guide to caring for them — so the pieces in your knitwear rotation are still beautiful in ten years.
Why Wool Asks for Less, Not More
Wool fibres carry a natural coating of lanolin that resists dirt and odour, which means a jumper rarely needs washing after each wear. Most of the time, airing is the answer: hang the piece somewhere ventilated overnight and it resets itself. Spot-clean small marks with a damp cloth rather than committing the whole garment to water. As a rule, a wool knit worn over a tee or fine tank needs a true wash only a handful of times each season — layering a soft base from our tops and tanks edit under your knits stretches the time between washes even further, which is better for the garment, the water bill and the planet alike.
How to Wash a Wool Jumper, Step by Step
When a knit genuinely needs washing, gentleness wins. Fill a basin with cool to lukewarm water — comfortable to your hand, never hot — and add a small amount of a dedicated wool wash. Submerge the knit, press the water through it softly, and let it sit for around ten minutes. Do not rub, twist or wring; agitation and heat are what felt and shrink wool, not water itself. Rinse in water of the same temperature until it runs clear, then press — never wring — the excess out against the side of the basin.
If you prefer the machine, use it only when the care label allows: wool or hand-wash cycle, cold water, low spin, wool detergent, and the knit turned inside out in a mesh bag. When in doubt, the basin is ten minutes of near-zero risk.
Drying and De-Pilling Without Drama
Gravity is knitwear's enemy while wet — a hung jumper becomes a longer, sadder jumper. Instead, lay the piece flat on a clean towel, roll the towel to press out moisture, then reshape the knit on a fresh dry towel away from direct sun and heaters. It will take a day or two; wool rewards patience. The tumble dryer is never the answer.
Pilling, meanwhile, is not a flaw — it is simply short fibres surfacing with friction, and it happens to beautiful knits as readily as basic ones. A cashmere comb or fabric shaver run lightly across the surface lifts pills away in minutes and returns the piece to new. Do it at the end of each season and your knitwear stays photograph-ready for years.
Cashmere, Merino and Blends
The method flexes slightly with the fibre. Cashmere is the most delicate of the lot — always cold water, always minimal handling, always flat to dry — and it rewards that care by softening with age rather than wearing out. Merino is more forgiving; many merino pieces tolerate a gentle machine cycle when the label allows, which is why the fibre turns up so often in everyday knits. Blends follow the most delicate fibre in the mix: a wool and cotton knit is washed like wool, not like cotton, and anything with a percentage of cashmere is treated as cashmere outright. Synthetic-blend knits are sturdier in the wash but tend to pill faster, so the comb earns its keep there too. And when the care label and any guide disagree, the label wins — it was written for that exact garment. The habit that matters most is the same across every fibre: wash rarely, wash cold, dry flat.
Storage, Moths and the Off-Season
Knits live folded, never on hangers — hangers leave shoulder peaks and stretch the body. When the warm months arrive, wash or air everything first, because moths are drawn to the invisible traces of wear, then store knits in breathable bags or drawers with cedar blocks or lavender. Come the first cold snap, everything emerges ready rather than wounded. This is the quiet heart of conscious dressing: care is what turns a purchase into a keeper. It is the same philosophy behind our guides to washing linen and making good pieces last — buy well once, care for it properly, wear it for years.
The Knits Worth Caring For
Care rituals only matter when the piece deserves them, and the Tuchuzy knitwear edit is chosen on exactly that basis — construction first, trend second. A soft neutral layer like the Samsøe Samsøe Sanoura Cardigan in egret is the kind of piece these habits are built for: worn constantly, washed rarely, kept forever. Ground your knits with easy pieces from our loungewear collection on slow mornings, or sharpen them over tailoring from the in-house Chosen by Tuchuzy label when the day asks for more.
We have been helping Bondi dress for coastal winters since 1995 — visit us on Hall Street and we will talk you through the knits in person. Further afield, Tuchuzy ships worldwide, including to the United States, where the seasons run opposite to ours — so someone, somewhere, is always pulling their favourite jumper back out.
Your Questions Answered
Can I machine wash a wool jumper?
Only if the care label allows it, and only on a dedicated wool or hand-wash cycle: cold water, wool detergent, low spin, ideally inside out in a mesh bag. If the label says hand wash or dry clean, believe it — a basin takes ten minutes and carries almost no risk.
Why did my jumper shrink, and can I fix it?
Heat plus agitation felts wool fibres together — usually a warm machine cycle or a tumble dryer. Mild shrinkage can sometimes be eased by soaking the knit in lukewarm water with hair conditioner and gently stretching it back to shape while damp, but true felting is permanent. Prevention is the real cure.
How often should I wash my knitwear?
Far less than you think. Air knits between wears and wash only when genuinely needed — for many pieces that is a few times a season. Wearing a fine layer underneath keeps knits fresher for longer.
How do I get rid of pilling on a jumper?
Use a cashmere comb or a fabric shaver, working lightly across the surface with the knit laid flat. Pilling is normal friction, not poor quality, and removing it takes minutes.
How should I store wool over summer?
Clean or air everything first, fold rather than hang, and store in breathable bags or drawers with cedar or lavender. Moths seek out traces of wear, so never store a knit unwashed for months.
Do I need a special detergent for wool?
Yes — regular detergents and anything with enzymes or bleach are too harsh for protein fibres and will slowly degrade the knit. A dedicated wool wash is gentle and low-sudsing, and some formulas do not even need rinsing, which makes hand washing quicker still. One small bottle lasts for seasons, because wool is washed so rarely.
