How to Care for Wool Jumpers So They Last for Years

Wool is naturally odour-resistant and needs washing far less than you think. Most damage comes from over-washing and moths.

Written by Leah Okafor

A good wool jumper can last for decades. Many do not, because they are shrunk in a hot wash, stretched on a hanger, or eaten by moths in a drawer.

Caring for wool properly is mostly about doing less.

Wash less

Wool fibres resist odours and stains better than cotton or synthetics. Often, airing a jumper overnight by an open window is enough. Spot-clean small marks with a damp cloth.

When you do wash it

  • Use a wool or delicates programme, or hand wash in cool water
  • Use a detergent made for wool โ€” ordinary detergents and enzymes can damage fibres
  • Do not wring; press water out gently or roll it in a towel
  • Dry flat, away from direct heat, reshaping it while damp
  • Never tumble dry unless the label says it is safe

Store it properly

Fold knitwear rather than hanging it, which stretches the shoulders. Store clean โ€” moths are attracted to body oils and food traces. Cedar blocks or lavender bags can deter them, and sealed bags or boxes protect items during summer.

Deal with bobbling

Pilling is caused by friction and is normal, especially under the arms. A fabric shaver or wool comb removes bobbles quickly. It is a sign of wear, not poor quality.

Fixing small holes

Small holes are easy to darn with matching yarn, and visible mending with contrasting colours has become popular. Fixing a hole early stops it unravelling further.
