How to Care for Wool and Knitwear Blazers: The Complete Guide

Follow these six steps to keep your Wool & Knitwear Blazers in top condition all year round.

1. Washing Wool & Knitwear Blazers

Wool is a natural fibre that doesn't need frequent washing. Over-washing is one of the fastest ways to ruin it.

  • Spot clean first. For minor marks, use a damp cloth and a small amount of mild detergent. Blot — never rub.
  • Hand wash when needed. Use cold water and a wool-specific detergent. Gently squeeze — never wring or twist.
  • Machine wash with caution. If the care label allows it, use a delicate or wool cycle with cold water and a mesh laundry bag.
  • Never use hot water. Heat causes wool fibres to shrink and felt — permanently.

2. Preventing and Removing Pilling

Pilling is caused by friction and is completely normal, especially on finer knits. Here's how to manage it:

  • Use a fabric shaver. Gently run it over the surface to remove pills without damaging the fabric.
  • Wash inside out. This reduces surface friction during washing.
  • Avoid wearing a backpack over knitwear. The straps cause heavy friction on the shoulders.
  • Store folded, not hung. Hanging knitwear causes it to stretch and pill at the shoulders.

3. Drying Wool Correctly

  • Never tumble dry. The heat and agitation will shrink and felt your garment.
  • Lay flat to dry. Reshape the garment while damp and lay it on a clean towel away from direct sunlight.
  • Allow full drying time before storing. Damp wool stored in a wardrobe can develop mildew and odour.

4. Dry Cleaning Suits and Blazers

Wool suits and structured blazers are best left to the professionals. Caring for Wool & Knitwear Blazers means knowing when not to DIY.

  • Dry clean sparingly — once or twice a season is enough. Over-dry-cleaning strips natural oils from the wool.
  • Steam between cleans. A handheld garment steamer removes wrinkles and refreshes the fabric without the harshness of dry cleaning.
  • Air your suit after wearing. Hang it on a wide, shaped hanger and let it breathe for at least 24 hours before returning it to the wardrobe.

5. Storage Tips for Wool & Knitwear Blazers

  • Use cedar balls or blocks in your wardrobe to repel moths naturally — moths love wool.
  • Store knitwear folded in a drawer or on a shelf, never on a hanger.
  • Use breathable garment bags for suits and blazers — avoid plastic, which traps moisture.
  • Clean before storing for the season. Moths are attracted to body oils and food residue left in fabric.

6. Quick Fixes

  • Shrunk your jumper? Soak it in lukewarm water with a tablespoon of hair conditioner for 30 minutes. Then gently stretch it back to shape while damp.
  • Snag in your knitwear? Use a blunt needle to carefully push the pulled thread back through to the inside of the garment. Never cut it.
