How to Wash Wool
Wool will felt and shrink the moment heat, friction, and moisture combine — understanding why tells you exactly what to do instead.
Hand washing cashmere is one of those tasks that sounds fussier than it actually is. Once you have the method down — the right basin, the right detergent, and the discipline to dry flat — it becomes a quick, low-stress routine. We see a lot of cashmere come through our facility in Maple Ridge that has been damaged not by accident but by a rushed rinse, the wrong soap, or hanging it wet. This guide covers every step so you can avoid the same outcomes.
Run your eye over the garment before you put it near water. If the care label says dry clean only, that label is there for a reason, and the safest move is to honour it. If the sweater is heavily structured, beaded, or already misshapen, professional cleaning will achieve better results than anything you can do at home.
For standard knit cashmere with a hand-wash or gentle-machine-wash label, proceed with confidence.
Use a clean sink, basin, or large bucket. Fill it with enough cool to lukewarm water to allow the sweater to move freely. Add a small measure of cashmere-safe detergent — check the product label for dosage, because a little genuinely goes a long way — and swirl it in before adding the garment. Adding detergent after the sweater is already in the water makes it harder to distribute evenly.
Submerge the sweater fully and use slow, gentle up-and-down pressing motions. There is no need to agitate vigorously; the goal is to allow the water and detergent to penetrate the fibres and carry away dirt and oils. A short soak of two to four minutes is usually enough. Do not rub one section of fabric against another, and do not twist or wring at any point during this stage.
This is the step people most often rush, and it matters more than most realise. Drain the basin and refill with clean water at the same temperature. Press the sweater gently to push soapy water through the fibres. Drain and refill again. Repeat until the water coming through the garment is entirely clear and free of suds. Soap residue left in cashmere fibres dries stiff and makes the next wash harder.
Lift the sweater from the basin with both hands supporting its weight. Give it a gentle squeeze — not a twist — to release most of the rinse water. Place it on a thick, clean towel, smooth it out roughly to shape, and roll the towel and sweater together. Press along the roll firmly. This towel method pulls a significant amount of moisture out of the fibres without any mechanical stress.
Unroll, transfer the sweater to a fresh dry surface — a mesh rack or a clean dry towel — and take a moment to reshape it. Pull the body to the correct length and width, smooth the sleeves, and set the neckline. Leave it to air dry completely before folding or storing. Avoid direct sunlight, which can fade colour, and never hang the sweater while it is wet.
If the sweater has a set-in stain you could not pretreat successfully, persistent odour, or noticeable distortion from a previous wash, our team can assess it properly. We handle hand-knit and designer cashmere regularly, and knowing when to step back from the basin is as important as knowing how to use it.

Silk is washable at home if you test for colour bleed first and use a gentle no-rinse detergent — skip either step and the results can be irreversible.
Linen is more forgiving than its reputation suggests, but hot water and overdrying will turn a crisp summer favourite into a wrinkled, shrunken shadow of itself.
