01
Read the label before filling the sink
Wool jumpers are not all made or finished the same way. A label that permits machine washing gives different instructions from one that says hand wash or dry clean only. Check the temperature and drying symbols as well as the washing method. Woolmark puts the garment’s care instructions first, and so should you. If the label is missing, ask the maker or a cleaner familiar with knitwear rather than treating a general internet tip as permission to wash an unfamiliar garment.

02
Choose a wash only when it needs one
After wearing, let the jumper air and check for marks or odour before putting it into a routine wash. Wool does not need washing simply because a T-shirt would. A spill does need attention, but the right treatment depends on the stain and garment. Avoid experimenting with bleach, strong household cleaners or a stain-removal method intended for cotton. Keep a simple note of the care instructions for favourite pieces so you are not trying to decode a faded label when something gets spilled. (Woolmark — Caring for wool)

AT A GLANCE
Read the instruction, then choose the action
The care label on your garment takes priority over this general guide.
| Label or situation | What to do | Avoid |
|---|---|---|
| Machine wash permitted | Use the specified wool programme and wool detergent | An ordinary mixed wash |
| Hand wash | Use the permitted temperature and gentle handling | Scrubbing and wringing |
| Dry clean only | Use an appropriate professional cleaner | Assuming all wool can be washed at home |
| Wet knitwear | Support, reshape gently and dry flat | Hanging by the shoulders |
| Tumble dry not permitted | Air-dry flat in the shade | A quick warm dryer finish |
04
If machine washing is allowed
Use the wool setting specified by the garment and machine instructions, with a suitable wool detergent. Woolmark advises turning the jumper inside out or using a laundry bag. Keep the load appropriate to the machine’s wool programme rather than adding the jumper to a full ordinary wash. A quick everyday cycle is not automatically gentle enough. If the machine lacks a wool setting, check the garment and machine guidance before selecting an alternative. The important combination is permitted temperature and gentle handling, not speed.

05
If the label calls for hand washing
Use clean water at the permitted temperature and a wool detergent in the amount directed on its packaging. Handle the jumper gently; avoid vigorous rubbing, twisting or wringing. Rinse as instructed, then lift it with support beneath the wet fabric. Woolmark’s hand-washing guidance is a useful reference, but the garment label still takes priority. Prepare the drying space first so you are not carrying a dripping, heavy jumper by the shoulders while looking for somewhere to put it. (Woolmark — How to wash wool)
06
Drying is part of keeping the fit
Lay the jumper flat on a clean, pale, lint-free towel or a suitable mesh drying rack. Gently arrange it into its natural shape, with sleeves supported. Keep it away from direct heat and strong sun, and change a saturated towel if needed. Hanging a wet jumper can stretch it under its own weight. Woolmark allows tumble drying for garments specifically labelled for it; otherwise, flat drying is the useful default. Let the jumper dry fully before folding it away. (Woolmark — How to dry wool)
07
Deal with bobbles gently
Pilling means the small balls of tangled fibre that appear where fabric rubs. It can happen on good knitwear too, so it is not a complete quality verdict by itself. Woolmark recommends reducing abrasion and avoiding fabric softener. If removing pills, use a tool suitable for that particular knit and follow its instructions, testing gently in a discreet area. Do not pull at them with your fingers or attack a fine knit with an exposed blade. A damaged stitch is harder to fix than a few bobbles. (Woolmark — What is pilling?)
08
Fold it clean and dry
Before putting wool away for a season, clean it according to its label and make sure it is completely dry. Fold knitwear rather than stretching it over a hanger, and store it somewhere clean and dry. Check stored garments from time to time rather than assuming a closed drawer solves everything. If a jumper has already shrunk badly, do not count on a home remedy to restore its original fit. Ask a knowledgeable cleaner or repairer what is realistic before spending money on another treatment. (Woolmark — How to store wool clothes)
