DIY - Wool wash

diy low- and zero-waste slow living May 12, 2021

It’s getting to that time of year when my knitted sweaters are almost being packed away, and washing them in this wool wash is a great way to clean them, and also keep them free of moths.

Growing up in Australia one of the things that I learnt was how to make a great wool wash using a few simple ingredients. Along with being a great budget alternative to shop-bought washes what I really like about it is that it is also a natural moth deterrent.

DIY wool wash

You will need:

  • 4 cups of pure soap flakes (or grate some soap if you cant find flakes)

  • 1 cup of methylated spirits (or rubbing alcohol)

  • 50ml of eucalyptus oil (or lavender. Both of these essential oils repel insects)

Step 1

Mix the methylated spirits (or rubbing alcohol) with the soap flakes.

Step 2

Add the eucalyptus oil (or lavender) and stir.

Step 3

Store the wool wash in a wide necked jar.


To clean your knits using this wool wash, use one tablespoon of mixture per garment. Dissolve in a small quantity of hot water and then pour into a basin of lukewarm wash water. Soak garment.

There’s no need to rinse (but I do, the sweaters still smell lovely and fresh). Squeeze and roll in towel to remove excess water. Dry flat and out of direct sunlight.
