An Expert Guide: How to Wash Woolen Jumpers

Woolen jumpers are classic wardrobe staples, loved for their warmth, comfort, and durability. 

To keep your woolen jumpers looking like you just bought them, it’s important that you wash them in specific ways. 

In this expert guide, you’ll learn the step-by-step process of washing a woolen sweater, so that you can preserve its quality and extend its lifespan.

Step 1: Check for precautions

Before you start the washing process, take a moment to carefully read the care label attached to your woolen jumper. 

Pay close attention to any temperature limits, recommended washing methods, or additional precautions mentioned.

Step 2: Pre-treat stains

To remove stubborn stains, we recommend that you pre-treat them before washing. Gently blot the affected area with a clean, damp cloth or sponge. Avoid rubbing vigorously, as this may cause the stain to spread or damage the fabric.

Step 3: Choose the right washing method

Hand washing:

  1. Fill a clean sink or tub with lukewarm water. Avoid using hot water, as it can cause wool to shrink or lose its shape.
  2. Add a mild wool detergent specifically made for delicate fabrics. Avoid using regular laundry detergents, as they often contain harsh chemicals that cause damage woolen fibres.
  3. Gently submerge the woolen jumper in the water, making sure that it’s fully immersed. Gently swirl it around, allowing the detergent to penetrate the fibres.
  4. Let the sweater soak for 10-15 minutes, then drain the soapy water.
  5. Refill the basin with clean lukewarm water and rinse the sweater, gently squeezing out the excess water without wringing or twisting.
  6. Repeat the rinsing process until no detergent residue remains.
  7. Carefully lift it from the water and gently press it against the side of the basin or sink to remove excess water.

Machine washing

While hand washing is recommended for woolen jumpers, some modern washing machines now have specialised wool or delicate cycles that can be used with caution. If choosing this method, follow these steps:

  • Place the woolen jumper inside a mesh laundry bag designed for delicate items. This will help protect it from excessive agitation and friction.
  • Use a mild wool detergent, following the dosage instructions provided.
  • Select the wool or delicate cycle on your washing machine, ensuring that the water temperature is set to cool or lukewarm.
  • Start the cycle and allow the machine to complete the wash.

Step 4: Drying techniques

To maintain the shape and quality of your woolen jumper:

  • Lay a clean, dry towel on a flat surface and place the sweater on top of it.
  • Gently reshape the sweater to its original dimensions, smoothing out any wrinkles or creases.
  • Allow the sweater to air dry naturally, avoiding direct sunlight or heat sources that may cause shrinkage or damage.
  • Flip the sweater occasionally for even drying. 

Step 5: Finishing touches 

Once your jumper is dry, there are a few additional steps to help keep your jumper looking pristine:

  • Use a soft, bristle brush or a garment comb to gently remove any remaining lint or fuzz from the surface of the sweater. Brush in one direction to avoid damaging the fibers.
  • To relax any minor wrinkles and restore the garment's shape, lightly steam the sweater using a handheld steamer.
  • Avoid hanging your woollen jumpers for extended periods, as this can cause the fabric to stretch.

Protection from moth damage

Unfortunately, Spring and Summer are the seasons when moths start to wreak havoc on woolens, leaving unsightly holes and ruining them. 

  1. Moth-Proof Storage Bags: Invest in high-quality moth-proof storage bags specifically designed to protect woollens, while allowing the natural fibres to breathe. These bags are made from materials that prevent moths from accessing and destroying your precious garments. 

  2. Avoid Plastic Bags: Refrain from using plastic bags for long-term storage, as they can trap moisture and promote the growth of mould. Wool fibres need to breathe, and plastic restricts airflow, which can lead to musty odours and potential damage.

  3. Cedar or Lavender: Consider placing natural moth deterrents, such as cedar balls or lavender sachets, inside the storage bags or containers. These aromatic options act as natural repellents, helping to keep moths at bay.


Additional tips:

  • Avoid using bleach, fabric softeners, or harsh chemicals when washing woolen sweaters, as they can cause damage and discoloration.
  • If in doubt about the appropriate washing method, it is generally safer to hand wash your woolen sweater to maintain its integrity.
  • Consider using specially formulated wool wash or wool conditioner to add an extra layer of softness and protect the fibers.
  • It is recommended to wash woolen sweaters sparingly, as excessive washing can cause them to lose their shape and quality. Instead, opt for spot cleaning or airing them out to refresh between washes.

When you know how it’s done, caring for your wool jumpers doesn't have to be hard, or take long. 

By following these simple steps, you can confidently wash your garment, ensuring it remains clean, soft, and long-lasting. 

Remember to always read and follow the care instructions provided by the manufacturer and treat your woolen sweaters with the gentle care they deserve.

With proper maintenance, your sweaters will continue to be cherished wardrobe staples for years to come.
