Can I hand-wash a wool sweater labelled dry-clean only?

No. The label may reflect dyes, linings, finishes or construction that are unsuitable for water. Follow the manufacturer’s instructions or consult a professional cleaner rather than testing this method on the whole garment.

What temperature should the wash and rinse water be?

Use cool water, following the garment’s care label, and keep the rinse water at roughly the same temperature as the wash. Avoid hot water and sudden temperature changes, which can contribute to felting or shrinkage.

What if my wool sweater feels smaller after washing?

Do not pull aggressively or heat the garment. While it is damp, gently smooth it toward its original measurements and dry it flat. A severely felted or shrunken sweater may not return to its former size.

Can I hang my wool sweater to dry or use a tumble dryer?

Usually no. Heavy wet knitwear can stretch on a hanger, and tumble-dryer heat may cause shrinking or felting. Unless its care label expressly permits a different method, reshape the sweater and dry it flat on a clean towel or suitable mesh rack.

Step 01 / 06

Check the care label and inspect the sweater

Read the care label before you wet the garment. Continue only if hand-washing is permitted; follow any more restrictive fibre, dye or trim instructions. If the label says dry-clean only, do not use this method. Check for loose seams, fragile embellishments and colour transfer by dabbing an inconspicuous area with a cool damp white cloth. If dye transfers noticeably or the fabric seems unstable, stop and seek specialist cleaning. Remove loose items from pockets.

2. Prepare a cool, gentle wash

Clean the basin so no bleach or other cleaner remains. Fill it with enough cool water (usually around 20°C or lower, following the garment label) to submerge the sweater. Add a small amount of detergent specifically marked safe for wool, following its dosage guidance, and mix gently. Avoid hot water, ordinary biological detergent, bleach and fabric softener unless the care label explicitly allows them.
3. Soak and wash without rubbing

Turn the sweater inside out if suitable for its construction, lower it into the prepared water and gently press until thoroughly wet. Allow a brief soak of about five minutes unless the detergent label specifies otherwise. Swish and press the fabric very gently to release everyday soil. Do not scrub, twist, stretch or vigorously agitate the knit: friction and temperature changes can cause wool to felt or shrink.
4. Rinse gently in cool water

Lift the wet sweater with both hands, supporting its weight so it does not hang and stretch. Drain the soapy water. Refill with clean cool water at approximately the same temperature, lower the sweater back in and gently press to release detergent. Repeat with fresh water as needed until the rinse runs clear and little detergent remains. Avoid twisting or wringing the garment.
5. Press out water with a towel

Support the sweater as you lift it from the basin and gently press out some water between your hands without wringing. Lay it flat on a clean dry towel, straighten the knit, then roll towel and sweater together into a loose cylinder. Press the roll to transfer moisture into the towel. Unroll carefully; use a second dry towel if the sweater is still very wet.
6. Reshape and dry completely flat

Place the sweater on a fresh dry towel or suitable mesh drying rack in a ventilated spot away from direct sun, heaters and strong heat. Smooth its body, hem, sleeves and cuffs back toward their original measurements without pulling. Leave it flat until fully dry, turning or replacing the towel when needed. Never hang a heavy wet wool sweater; only store or wear it when completely dry.
