Wool is a natural fibre that we love to cuddle up with on cold winter nights! You can’t go wrong with a wool blanket, a woolly jumper or a much-loved woollen hat.

But how do you wash wool without messing it up? Find a complete guide to washing wool below!

Follow the tips and steps below to clean your woollen items.


Tips to Consider When Washing Wool

Here are a handful of tips you should think about when cleaning any kind of woollen item:

  • Don’t use fabric softener.
  • Choose a gentle washing cycle.
  • Either choose a low spin speed on the washing machine, or skip the spin cycle altogether.
  • Don’t dry wool in direct sunlight.
  • Try to remove all your jewellery before starting the cleaning process. Rings and bracelets have a tendency to catch and snag wool.
  • Test your chosen laundry detergent out first by applying a small amount to a hidden seam.
  • Choose a product that has the Woolmark certification, meaning it is safe to use on wool.
  • You should air dry wool as this is safer than other drying methods.
  • Wash wool items inside out.
  • Don’t wring the water out of your woollen items. It’s better to roll your wet items up in a towel and press the moisture out of them.
  • Check the care label on your woollen item(s) to see how it should be cared for.
  • Don’t scrub your wool, however tempting it may be! This could potentially damage the delicate material.

How to Dry Wool

It’s usually better for your wool if you air dry it naturally. This’ll stop any potential shrinking from happening, and should help to keep your item in better shape for longer.

To dry wool simply:

  1. Gently pull the item, particularly if it’s a jumper, into its original shape.
  2. Pop some neutral-coloured towels down on a flat surface.
  3. Lay your wool on top of the towel. Make sure it’s flat out and not crinkled up. Avoid hanging wet wool up because it can stretch out of shape easily.
  4. You can roll the wool up inside the towel to extract moisture from it.
  5. Unroll the towel.
  6. Leave the wool to dry flat out on the towel.
  7. Try not to leave the item to sit in direct sunlight.
  8. When the item is dry, store it. If you’re going to hang an item up, use soft hangers with padding.

It is possible to dry some items made from wool in a tumble dryer, but as mentioned above, it’s usually better to air dry woollen products.

If you’re going to use a dryer, make sure you check the care label on your woollen item first.

Once you’ve done this you can dry the item, but make sure you use a very low heat setting/wool setting, only run very short cycles, and pull your woollen item(s) out of the dryer before it’s completely dry. You can then dry the items naturally for the last few minutes.

If ever you’re in doubt about drying your woollen items in a dryer, just don’t do it. Instead, stick to a more natural method!

Can You Machine Wash 100% Wool?

It is possible to wash items that are made from 100% wool in a washing machine as long as the care label states it is safe to do so.

If the care label states that you should ‘Hand wash’ or ‘Dry clean only’ an item, then this is how you need to take care of the item in question. Not adhering to the advice on the tag might result in you damaging the woollen item.


What Happens If You Wash Wool That Is ‘Dry Clean Only’?

If you forget to check the care label, or you ignore the advice on the tag, and you go ahead and clean your woollen item in the washer, your item might come out of the wash looking a tad worse for wear!

It’s likely that your wool might’ve shrunk, particularly if you used hot water, and you might see some felting reaction happening between the wool’s fibres.

It may not be the end of the world for the item in question, and you may be able to undo some of the damage. But ideally you don’t want to put your wool in this situation in the first place.

It’s always best to check an item’s care label before you wash it. And you should definitely make a point of doing this when you’re handling delicate materials, like wool, which are usually expensive!

And remember, if ever you see ‘Dry clean only’ you really need to stick to this advice!

What Happens If You Wash Wool in the Washing Machine?

If you wash wool in a washing machine correctly (with a gentle cycle, cold water and wool-friendly detergent), your woollen item should leave the appliance in a good, clean condition.

If you wash your wool in a washing machine on the wrong cycle, in water that’s too hot and with an unsuitable detergent, you’re probably going to be facing a mountain of woolly problems.

It’s very likely that your woollen item will have shrunk, and it may even be a little snagged if it’s been agitated too much.
