How to Wash a Cashmere Jumper

Luxurious, soft, and incredibly warm, cashmere jumpers are frequently wardrobe favourites, especially when it's cold outside.

However, the delicate nature of cashmere fibres need specific care to maintain their softness, shape and longevity.

In this article, we’ll guide you through the essential steps of how to wash a cashmere jumper by hand and share best practices for cashmere jumper care.

Why Wash Cashmere by Hand?

Cashmere is made from the fine fibres of the soft undercoat of cashmere goats. These fibres are both softer and lighter than wool, yet can be a great deal more insulating.

Due to these fine fibres, machine washing, even on a gentle cycle, can  result in shrinking, stretching, or pilling. Hand washing is gentler and helps preserve the integrity of the fibre, making your cashmere jumper last longer.

Your Step-by-Step Guide to Hand Washing a Cashmere Jumper


  1. Preparation

  • Make sure that your sink is clean and free from any residue that might transfer to your jumper.
  • Fill the sink with lukewarm water; hot water can shrink cashmere, while cold water may not effectively clean it.
  1. Use a mild detergent

Regular detergents can be too harsh and damage cashmere fibres. While you can purchase expensive shampoos designed for delicates or cashmere, we have found that Johnson's Baby Shampoo works a treat.

Make sure to mix the shampoo completely in the water before submerging your jumper in order to avoid its direct contact with the concentrated soap.

  1. Wash Gently

  • Submerge your jumper and gently swish the soapy water through the fabric.
  • Avoid rubbing or twisting, as this can reshape the delicate fibres.
  • Let your clothing soak for up to 30 minutes.
  1. Rinse Thoroughly

  • Drain the soap water and gently rinse your jumper under mild running water.
  • Continue rinsing until the water runs clear and there are no soap bubbles left.
  1. Dry Well

  • When drying, make sure not to wring out the cashmere - twisting can distort its shape. 
  • Instead, lay the jumper flat on a clean, dry towel. Roll the towel and jumper together to press out excess water.
  • Next, place your jumper flatly on a drying rack or another clean towel, away from direct heat or sunlight.

Cashmere jumper care: Protect your cashmere jumper from moth damage 

To protect your cashmere from destructive moth holes, it’s critical to store it in the right way. Firstly, make sure your cashmere jumper is clean before you store it away. Moths are drawn towards sweat, body oils and food particles. 

Use protective storage

Cashmere protection pouches are designed to prevent moth damage. The breathability of the pouches helps the cashmere fibres to breath. This prevents moisture build up, which attracts moths and leads to mildew. Storing your cashmere in protective pouches will also keep your favourite clothes safe from dust accumulation. 

Apply natural moth repellents 

From cedar balls to lavender sachets, you can repel moths from your wardrobe with natural products, and without using harsh chemicals. The added benefit of these solutions is that they leave your clothes smelling fresh too.

Washing and caring for your cashmere jumper doesn’t have to be difficult. By following these steps and tips, you can make sure that your favourite jumpers stay as luxurious as when you bought them. With the right care, your cashmere can remain a treasured part of your wardrobe for years to come.
