How to wash jumpers without pilling, shrinking or stretching

Quick answer: wash jumpers in cool water, inside out, squeeze gently without rubbing, press water out with a towel instead of wringing, then dry flat. Shrinking usually comes from hot water and rough handling; stretching from hanging it while heavy with water; pilling from friction with other items.

Why jumpers get damaged

Problem	Usual cause
Shrinking	Hot water, rough rubbing, hot tumble drying
Stretching	Hanging on a hanger while soaking wet
Pilling	Friction with jeans and zips; washing with rough items

Hand-washing a jumper

1. Turn it inside out.
2. Dissolve detergent in a basin of cool water before adding the jumper.
3. Soak 5–10 minutes, gently squeezing the collar and underarms. Don’t scrub or twist.
4. Rinse 2–3 times in cool water at the same temperature.
5. Press out water: roll it in a dry towel and press gently.

Machine washing (if the label allows)

• Put it inside out in a mesh bag.
• Choose the Wool or delicate programme, cool water and a low spin.
• Wash separately from jeans, items with metal zips and towels.

Drying

• Dry flat on a mesh rack or a dry towel, easing it back into shape.
• Keep it away from harsh sun and direct heat.
• Turn it over so it dries evenly; fold only when fully dry.

Already pilled?

Use a fabric shaver or de-pilling comb on the jumper laid flat. Next time, wash it inside out and separately to cut friction.

Choosing a detergent for jumpers

• Liquid, easy to dissolve and rinse, in a moderate dose.
• Wool and cashmere: follow the label; many brands recommend a dedicated wool detergent.
• Everyday acrylic or cotton knits: a gentle liquid 2-in-1 is enough. URA has a gentle formula for everyday hand washing, keeping clothes soft, with less pilling and better shape. For a small hand-wash basin, use less than the dose on the pouch.
