How to care for merino knitwear

Merino knitwear is loved for its softness, lightweight warmth and versatility. Whether you have a favourite merino wool jumper, cardigan or slipover, the right care can help keep it looking and feeling beautiful for longer.

How to care for merino knitwear

The good news is that caring for merino wool doesn't have to be complicated. A few simple habits — washing only when necessary, using a gentle wash, drying knitwear correctly and storing it carefully — can make a real difference.

In this guide, we'll explain how to care for merino knitwear, including how to wash merino wool, how to dry it, how to deal with bobbling and how to store your favourite pieces between seasons.

How often should you wash merino wool?

One of the benefits of merino wool is that it doesn't necessarily need washing after every wear.

Merino is naturally breathable and can help manage moisture and odour, meaning your knitwear can often be refreshed simply by airing it between wears.

If your merino jumper is clean and still feels fresh, give it some time to air rather than automatically putting it in the washing machine. Washing less frequently can help reduce unnecessary wear on the fibres and help your knitwear retain its shape and softness.

Of course, if your garment has been stained or needs a proper clean, follow the care label and wash it accordingly.

Do Avoid
Check the care label first Hot water
Wash only when necessary Washing after every wear
Use a wool-friendly detergent Bleach and harsh detergents
Choose a wool or delicate cycle Excessive agitation
Turn knitwear inside out Wringing or twisting
Dry flat where possible Hanging while wet
Reshape while damp Direct heat and radiators
Store knitwear folded Hanging knitwear for long periods

Always check the care label first

Before washing any merino wool clothing, check the care label inside the garment.

Although many modern merino garments are designed to be easy to care for, individual pieces can have different requirements depending on their construction and fibre composition.

The care label is the best guide for your particular garment.

For Country Collection knitwear, always follow the care instructions provided with your individual garment.

How to wash merino wool

Many merino wool garments can be machine washed, but they should always be washed according to their individual care label.

If machine washing is recommended:

  1. Turn your garment inside out.
  2. Choose a wool or delicate cycle.
  3. Use the temperature recommended on the care label.
  4. Use a mild detergent designed for wool or delicate fibres.
  5. Avoid overloading the washing machine.
  6. Remove the garment promptly once the cycle has finished.

Turning your jumper inside out can help reduce friction against the outer surface of the knitwear during washing.

For particularly delicate pieces, a mesh laundry bag can provide an additional layer of protection.

How to hand wash merino wool

If your garment recommends hand washing, use cool or lukewarm water rather than hot water.

Add a small amount of suitable wool detergent and gently move the garment through the water. Avoid vigorous rubbing, wringing or twisting, as these can put unnecessary stress on the fibres.

Rinse according to the detergent instructions, then gently press out excess water.

Never twist or wring a wet merino jumper.

Quick merino knitwear care tips

✔️ Wash only when needed 
✔️ Use cold water and wool detergent
✔️ Always wash inside out
✔️ Never tumble dry
✔️ Dry flat and reshape gently
✔️ Store folded, not hung
✔️ Protect from moths when storing

What detergent should you use for merino wool?

Choose a mild detergent specifically designed for wool or delicate fabrics.

Avoid harsh detergents, bleach and products that could damage or weaken delicate wool fibres. Fabric softener is also unnecessary for merino knitwear.

Using the right detergent helps preserve the natural feel of the fibres while keeping your knitwear clean and comfortable.

How to dry merino wool

Drying your merino knitwear correctly is just as important as washing it.

After washing, gently remove excess water without wringing or twisting the garment. Reshape the knitwear while it is still damp, paying particular attention to the sleeves, neckline and overall length.

Where possible, lay the garment flat to dry naturally.

Avoid hanging a wet jumper on a hanger or washing line, as the weight of the water can cause knitted garments to stretch and lose their shape. Woolmark also recommends flat drying wool knitwear where possible.

Keep your merino knitwear away from radiators and direct heat, and avoid drying it in strong direct sunlight.

Can you tumble dry merino wool?

Always check the care label before tumble drying.

Some wool garments carry a care claim that allows tumble drying on a low or wool/delicate setting, while others should be dried flat. If your garment does not specifically state that tumble drying is suitable, air drying is the safer option.

How to prevent merino wool from bobbling

Small bobbles, also known as pills, can develop on knitwear as a result of friction. Areas that experience regular rubbing — such as under the arms or around the sides of a garment — may be particularly prone to them.

Bobbling doesn't necessarily mean that your knitwear is poor quality; it is a natural result of friction and wear.

If bobbles appear, use a knitwear comb or suitable de-bobbler carefully across the surface of the garment.

Avoid pulling bobbles off by hand, as this can disturb the surrounding fibres.

To help minimise friction:

  • Wash knitwear inside out.
  • Avoid unnecessary washing.
  • Don't overload the washing machine.
  • Take care when wearing bags or accessories that rub against your jumper.

How to refresh merino knitwear between wears

You don't always need to wash your merino jumper to freshen it up.

After wearing, allow your knitwear to air before folding it away. An open window or well-ventilated room can help the garment feel fresh between wears.

You can also use a steamer carefully to remove light creases, provided the garment's care instructions allow it.

Giving your knitwear time to rest between wears can help reduce the need for frequent washing.

How to store merino wool

Correct storage is particularly important when putting knitwear away for a longer period.

Fold rather than hang

Merino jumpers and cardigans are best stored folded rather than hanging for long periods. Hanging can put pressure on the shoulders and neckline and may cause knitted garments to stretch.

Instead:

  • Fold knitwear neatly.
  • Store it on a shelf or in a drawer.
  • Avoid overcrowding.
  • Make sure garments are clean and completely dry before storing them.

How to protect merino wool from moths

Woollen garments can be vulnerable to clothes moths, particularly when they are stored for long periods.

To help protect your merino knitwear:

  • Store garments clean and completely dry.
  • Keep wardrobes and drawers clean.
  • Avoid leaving worn knitwear in storage.
  • Check stored garments regularly.
  • Consider using suitable cedar products as part of your moth-prevention routine.

If you notice signs of moth damage, deal with the problem promptly and follow appropriate garment and pest-control guidance.

Common merino wool care mistakes to avoid

A few simple mistakes can shorten the life of your knitwear.

Washing too frequently
If your jumper is clean and fresh, consider airing it rather than washing it.

Using hot water
Always follow the care label and avoid temperatures higher than recommended.

Using harsh detergent
Choose a detergent designed for wool or delicate fabrics.

Wringing or twisting
Wet knitwear is particularly vulnerable to stretching and distortion.

Hanging while wet
Dry knitwear flat where possible to help it retain its shape.

Drying on a radiator
Direct heat can damage wool fibres and affect the garment.

Pulling bobbles by hand
Use a suitable knitwear comb or de-bobbler instead.

Storing knitwear while damp or dirty
Always make sure garments are clean and completely dry before putting them away.
